Abstract

In agroforestry practices generally tree has more pronounced effect on crop growth and yield with increase in its canopy cover. But in the present investigations results indicated that there was no significant (P<0.05) effect of trees on crop. The survival, growth, biomass production and leaf nutrient content of Paulownia were significantly higher as compared with poplar under the agroforestry situation. Similarly, nitrogen (3.02 %) and protein (18.8 %) contents in tree leaves were also highest with the Paulownia clone-GP. Although, the size of the leaves and canopy of Paulownia is larger than the poplars even then influence on yield and yield attributing characters was lesser as the highest yield was recorded under Paulownia only. It is evident from the results that Paulownia and Poplar clones do not have any significant effect on almost all the growth and yield parameters of wheat and maize crops grown in association with trees. The grain yield for wheat crop has a very little difference but maize does not have the difference under the different clones. It indicates the best compatibility of the crops with Paulownia and poplar. it is inferred that over all Paulownia clone-GP out performed all the clones of Paulownia fortunei and Populus deltoides. Thus, the tree has great potential under agroforestry situations in similar agro-climatic conditions of India.

Abstract

A study was conducted to investigate the influence of 25 year old Syzygium cumini shelterbelt grown on north-south direction in single row on the growth and yield of Sorghum vulgare cultivated for fodder on western side of the belt. The results of the study show that mean green fodder yield, plant density and crop height were numerically lowest by 56.72 percent, 73.48 percent and 36.54 percent, respectively upto 5 m from tree belt as compared to the farthest plots located at 20.5 m distance in the open (control). Numerically higher values from these crop parameters were noted at later distances upto 8 m and beyond this uniform pattern'of growth and yield of S. vulgare was found. Therefore, it can be generalized that the impact oftree belt on Sorghum crop can be experienced upto 5 m, there is little impact upto 8 m distance and almost no impact beyond 8 m. The economic losses in green fodder yield in the affected area (220 m²) works out to 198.55 kg per 55 m tree line (one sided) are well compensated by the sale of timber harvested time to time by the farmer.

Abstract

In Northern India, use of Eucalyptus as windbreak/shelterbelt is well accepted but questions concerning the economic impact on crop production system requires through investigations. In this study, the influence of Eucalyptus trees on agriculture crop viz., Sorghum vulgare in terms of plant density, crop height and fodder yield were found negative in the vicinity of tree. Gross income from Eucalyptus trees for 100 m tree line estimated to Rs. 2144 for 61.35 trees in east-west and Rs. 2399.87 for 74.68 trees in north-south tree line. It was concluded that growing Eucalyptus on field boundaries under irrigated condition had very little impact on associated Sorghum crop and the crop losses due to tree line are well compensated by the income received out of sale of trees.

Abstract

Agroforestry studies using Dalbergia sissoo were conducted to assess the crop productivity under semi-arid conditions. Growth performance of D. sissoo trees intercropped with wheat and paddy showed mean height and gbh as 10.36 m and 53.45 cm, total timber 1.2554 m³ small timber 7.0899 m³ and fuel wood 77.45 q. The gross income from trees calculated as Rs. 24,056.00 for 33 trees pcr 55 m tree line. Crop yields and other crop parameters of wheat especially under tree canopy upto 4 m from tree line declined significantly. In case of paddy such influence was found upto 8m from tree row. The total affected area in the entire plot worked out to 220 m² in wheat crop and 440 m² in paddy crop showing a nct loss of 21.23 kg (Rs. 53.00) and 101.20 kg (Rs. 559.00), respectively. The losses to agriculture crops are wen compensated by the gross income Rs.2005/-per year obtained through sale of trees. The conclusions drawn from the studies indicate that D. sissoo trees though effect negatively the agriculture production in the vicinity of tree canopy but it proved viable proposition for practicing as a agroforestry tree species under irrigated conditions. The spacing between trees, pruning and manipulation of crown structure are crucial for minimising the tree losses and increasing the productivity per unit area.

Abstract

Thee paper presents the results on high density plantation of poplars and their avaliability for pulp and paper manufacture as a short rotation crop. The reaults of the study at the age of two years indicated that total air, dried bole-biomass was higher (i.e. 24.4 t/ha) In case of Populus × euramericana '72/58' as compared to Populus deltoldes 'G-3' (17.5 t/ha). At the age ot three years, P. deltoldes 'G-3' had taken the lead and contributed the highest total bole air dried biomass i.e. 52.6 t/ha aa compared to 37.8 t/ha by P. × euramericana '72/58'. At the age of three years for both P. deltoldes '0-3' and P. × euramericana '72/58' the total air dried above ground biomass (bole end branches) was of the order of 55.5 and 45.5 t/ha, reapectlvely. The evaluation of pulping and papermaking qualities on pilot acale, using the woody material of P. × euramericana '72/58' Ind P. deltoldes '0-3' indlclted that a 50 : 50 mixture of 2 Ind 3 years ega wood with bark is suitable for producing wrapping paper from both the species. The laboratory experlments showed that the same mixture with bark is also suitable for producing writing and printing papers.

Abstract

High temperatures generated by forest fires have a profound effect on seeds particularly those lying on the forest floor or buried in top layer of the soil. The seeds of different species are known to vary in their tolerance to high temperatures depending on their individual characters chiefly the type of seed coat. While soft seeds are consumed by the fire' the seeds of some species having hard seed coats actually need fairly high temperatures to break the dormacy and to induce germination. Such variations in heat tolerance behaviour of seeds account for the pattern of vegetational succession following burning of an area. Heat tolerance behaviour of seeds of forest as well as agricultural crops has been studied by many workers abroad but no such work appears to have been done in India. The results of a pilot laboratory trial on the seeds of Leucaena leucocephala are discussed in this paper. It has been found that dry heat treatment of 75°-80°C for 5 minutes actually increased the germination whereas temperature range of 125°-130°C for 5 minutes proved lethal for these seeds.

Abstract

Increasing attention is being paid to raising large leale plentations of Eucalyptus spp under Agro-Forestry throughout India to meet the demand for fore firewood, small timber, poles, beams, pape, pulp etc. A shift in the cropping pattern from agriculture to farm forestry has been experienced in the States of Uttar Pradesh, Punjab and Haryana. Eucalyptus has been planted by the formers on field bunds, along field boundaries, in roilS along water channels and in compact blocks in agriculture fields with variable spacings. The present paper presents the results in respect of economic reasibility or Eucalyptus raised with or without agrlculture on fields bunds and in blocks at varying spacings viz. 2.5 m×2.5 m, 3.0 m×1.5 m, 4.0 m×2.0 m and 6.0 m × 1.0 m on farm lands. Cultivation of Eucalyptus at wider spacing in combination with agriculture crops at 8 years rotation ensures high economic returns.

Abstract

An experiment having 15 treatments comprising of twelve provenance of chir pine (Pinus roxburghii) and one provenance each of P. caribaea. P. potula and P. kesiya was laid out in a rondomized block design with three replications and 36 plants per plot at the Forest Research Institute, Dehra Dun (India) during 1974, to select suitable provenances/species for afforestation under the sub-Himalayan conditions. The results of the study at the end of three years growth show that P. patula, P. caribaea and P. kesiya gave significantly better height increment than the different provenances of chir pine. lhe Dalhausie, Kulu, Nahan, Durkoti-Chamba and Bilaspur provenances of chir pine gave better diameter increment than P. caribaea, but these provenances of chir pine were inferior in diameter increment to P. patula and P. kesiya, there, however, being no significant difference in diameter increment between P. patula, P. kesiya and the Saraj provenance of chir pine. Different provenances of the indigenous chir pine gave significantly better survival per cent than the three exotic pines under trial. Based on the overall performance in terms of height and diameter growth and survival per cent, P. patula was adjudged as the best species followed by the Saraj, Debra Dun and Bilaspur provenances of chir pine.

Abstract

The paper presents the results of spacing trials on Pinus caribaea var. bahomensis. The growth data at 8-9 years of age indicate that P. coribaea does possess a potential of high yields and where tree size is not of mach importance as in the case of pulpwood, it should be planted dense i.e. at a spacing of 2 m². However, from the observation of the plots indicate unhealthy (lanky trees) under closer spacings. It is, therefore, likely that in the years to come the growth in plots with closer spacing may fa1l whereas under wider spacing the crop may continue to be healthier. It is probable that the best spacing might lie between 2 m² and 2.5 m². This could only be concluded after the experiment progresses for some more years.

An experiment based on 24 treatments comprising of 9 provenances of Pinus caribaea, 6 provenances of P. patula, 2 provenances of P. kesiya, 3 provenances of P. roxburghii and one each of P. gregii P. pseudotrobus, P.leiophylla and P. glabra was laid out in 1974 at the Forest Research Institute, in a randomized block desigrn with three replications to select suitable species/provenances of pines for afforestation under Dehra Dun conditions. The results of the study at the end of three years growth indicate that P. gregii of Mexico origin is the most suited species. The other species/provenances which have given encouring results are P. petula of Newzealand and Malawi orgins, P. caribaea of Nicargua - Alamicamba, and Guatemala-Deten region and P. kesiya of Thailand. The indigenous chir pine (P. roxburghii) of Debra Dun origin was better (or almost as good in overall performance) than certain provenances of P. caribaea, P. patula, P. kesiya and P. glabra. Intensive provenance trials and selection are indicated in the case of P. gregii, P. caribaea, P. kesiya and P. roxburghii.

Abstract

An experiment to find out the stage at which the pine seedlings should be pricked out from the germination boxes to the polythene bags for raising the nursery stock of Pinus caribaea, P. patula and P. elliottii, was conducted in the research nursery of the Forest Research Institute, Dehra Dun (India) during 1976-77. Five treatments comprising of direct sowing in polythene bags (T₁ ), pricking of seedlings into polythene bags immediately after start of germination (T₂), pricking after the seed coat falls from the cotyledons (T₃), pricking after the formation of terminal bud (T₄) and pricking when the terminal bud opens and starts growing (T₅ ), were tried in a randomized block design with five replications and 20 plants per plot. The results of the study show that the seedlings pricked after fall of seed coat gave significantly better height and diameter growth than the seedlings pricked at the other stages, there being no significant difference in between the seedlings pricked just after germination (T₂) and those pricked after fall of seed coat (T₃) for diameter growth in case of P.patula and P. elliottii and height growth in case of P. elliotii. The different stages of pricking had no significant effect on survival of the seedlings.Based on the overall performance of the seedlings, it is recommended that the young pine seedlings should be pricked from germination boxes into polythene bags just after the seed coat fall from the cotyledons, after germination.

The results of the study show that though bigger bags of sizes 12 × 20 cm and 12 × 25 cm gave somewhat better seedling growth, even the smaller bags of sizes 6 × 10 Cm 6 × 15 Cm and 6 × 20 Cm gave seedlings stock of comparable quality and that there was no significant advantage in using bags of bigger sizes. Keeping in view the results of the study, the cost and the convenience in carriage and handling etc. of the bags of different sizes, the smaller bags of size 6 × 15 cm and 6 × 20 cm are recommended for propagation of pine seedlings instead of bigger bags of 15 × 25 cm being used at present.

Abstract

Eight depths of sowing (viz., 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 cm) for three species of pines (viz, Pinus patula, p. caribaea and P. ellioltii) were tried in a randomised block design with four replications in the research nursery of the Forest Research Institute, Dehra Dun (India) to find out the optimum depth of sowing for 'propagation of the pines under Dehra Dun conditions. The results show that 0.5 and 1.0 cm deep sowings gave the highest emergence energy and germination value in case of P. patula and P. caribaea, while in the case or P. elliottii, 1.5 and 2.0 cm deep sowings proved better. 1.0 cm deep sowings gave significantly higher number of seedlings for P. patula as compared to the other depths tried. For P. caribaea also, 1.0 cm deep sowings gave the highest number of seedlings but there was no significant difference between the sowings done at 0.5, 1.0 and 1.5 cm. depths. In case of P. elliottii, 2.0 and 1.5 cm deep sowings gave higher number of seedlings. Based on the overall performance and development of the seedlings In-respect of commencement or germination, total germination germination value, biomass of the seedlings, number of seedlings obtained and survival percent etc., it was concluded that in case of P. patula and P. caribaea. the seed should not be sown deeper than 1.0 cm while for P. elliottii, the sowings should be between 1.5 to 2.0 cm deep.

Abstract

A nursery study on Pinus roxburghii, P. caribaea, and P. oocarpa was conducted in the research nursery of the Forest Research Institute, Dehra Dun (India) to find the effect of seed grading (by size) on germination and growth of pine seedlings. The results show that medium sized seed gave significantly higher mean total germination percent and plant percent as compared to the large or small sized seeds. Moreover, medium sized seed gave higher mean daily germination, peak value (of germination), germiuation value, total biomass, height growth and ischolar_main/shoot ratio of the seedlings as compared to the other two grades. Small sized seed gave significantly higher germination percent and germination value as compared to the large sized seed but the seedlings raised from large, sized seed had higher total biomass than the seedlings raised from the small seed. Seedlings of Pinus roxburghii had the highest Root/Shoot ratio and total biomass, followed by P. oocarpa and P. caribaea.

Abstract

As prolongation of the time of germination exposes the valuable seeds of Pinus caribaea & P. patula to several risks, trials were undertaken to use a number of cheap and easily available agents for hastening germination. HCI, HCIO₄, cowdung, boiling water and combinations of different durations of soaking and concentrations of H₂O₂, thiourea sol., KNO₃ sol. and water were tried. Lower strengths of H₂O₂ when used for shorter durations proved effective in both of the cases, albeit for P. patula soaking in water for 18 hrs at ambient temperature was best in increasing overall germination. Higher strengths of H₂O₂ and higher soaking periods proved inhibitive in case of P. patula; 0.25% to 0.5% thiourea sol. and 0.5% to 1% KNO₃ sol. inhibited germination of P. caribaea seed whereas cowdung and boiling water brought down the germination % of the both. Hydrochloric acids proved ineffective except in case of P. caribaea, but there too, it was inferior to H₂O₂ (3 to 6%) when used for 6 to 18 hrs.

Abstract

Wetlands near urban centres are under great environmental pressure due to residential, industrial and commercial developments. In south of Chennai, we have the Perungudi dumpsite in the Pallikaranai Marsh which is a low lying area and closes to the sea level. It is poorly drained and consists of an extensive area of marshy land permanently wet and seasonally inundated. This dumpsite does not have proper lining to prevent leachate migration into underlying and surrounding groundwater environment. There is no importance given for measurement of potential impacts of leachate generation from dumpsite on groundwater quality. Hence, the present works is taken to study the impact on groundwater quality around the Perungudi dumpsite. The study determines the major physico-chemical quality of groundwater and besides it compares COD for the pre-monsoon and post monsoon periods in the water samples in six observation wells in the same location both in dug wells and tube wells. The pH indicates alkaline nature in all the water samples and the EC content in post monsoon period reduces due to the rains which dilutes the water. In the present study, the total dissolved solids in all the water samples were high and exceeded the desired limit of the CPHEEO, 1999. In the case of Hardness, the values are higher during the premonsoon period and exceed the maximum permissible limit. COD in the water samples are higher in pre monsoon and lower in the post monsoon period. Pallikaranai is the only surviving wetland ecosystem of the Chennai city which is a curious watch for environmentalists and stakeholders. This study emphasizes the need to protect the dwindling common property resource.

Abstract

,i>Trichoderma species have long been recognized as agents for the control of plant disease and for their ability to increase plant growth and development. Morphologically characterized thirty rhizospheric isolates of Trichoderma (T. harzianum and T. virens) from different locations of Uttarakhand were evaluated under glass house condition for their plant growth promoting potential on paddy crop. Maximum ischolar_main and shoot growth promotion was achieved with isolate PB 15 (80.3%) and PB 8 (38.5%), respectively in paddy. Maximum length of flag leaf was recorded with isolates PB 23 (43.5 cm) and PB 16 (41.6 cm) while maximum width exhibited by isolates PB 23 (2.1 cm) and PB 8 (1.9cm). Maximum fresh and dry weight was recorded with isolates PB 18 (10.2g) and PB 23 (2.0393g), respectively.

Abstract

The separation of the regional gravity anomaly by any of the existing techniques has one common drawback, i.e. the Bouguer gravity values over the anomalous zone enter into the computations. In order to overcome this, a new scheme, based on the finite element approximation, is suggested to compute the regional anomaly. The uniqueness of this approach is that except a few discrete gravity values coinciding with the nodes of the element superimposing the map space, often very large, no other gravity data are invoked to compute the regional anomaly. As a case study, regional - residual anomaly separation has been carried out for the north west Ganga Basin. This area is chosen as it is tectonically very active, and based on the regional and residual gravity anomalies, we can unfold the imprints of various tectonic episodes along the lndo - Eurosian plate boundary. While the regional gravity anomaly shows possible association with deep-seated faults along the rivers Yarnuna and Chambal, the seismicity appears to be correlated with the residual gravity anomaly around Delhi.

Abstract

The present study evaluated bamboo (Dendrocalamus strictus) based resource conservation in the Yamuna ravines at Central Soil and Water Conservation Research and Training Institute, Research Centre, Agra, Uttar Pradesh, India. Ravine lands are highly degraded dry lands and 3.97 m ha area is affected by ravines in India. One ravine micro watershed of 2.8 ha area was planted with two rows of bamboo in staggered manner as vegetative barrier for the analysis of hydrological and economic aspect of bamboo plantation. Hydrological results showed that runoff has been reduced from 9.6% to 1.8% and soil loss from 4.2 to 0.6 t/ha/year in the last 4 years. Based on bamboo growth performance, average value of culm height and culm collar diameter have been recorded as 3.80 m and 22.50 mm, the value of average crown size and number of culms per clump being 3.93 m and 18 numbers respectively. Further, the soils under bamboo plants improved in terms of decreased pH and enhanced soil organic carbon. The economic analysis suggested a cash outflow of Rs 48,000 ha^-1 from 7th year onwards to the stakeholders in the region, in addition to the benefits accrued to society at large in terms of value of nutrient (Rs 2125-5555 ha^-1) saved through soil conservation. This study recommends bamboo plantation for productive and protective utilization of such degraded lands. It also suggests that the high cost of establishment for individual stakeholders can be met through subsidies and banks' financial inclusion programme in developing countries such as India. Further, public funding can also be routed through appropriate budgetary provisions in development plans of corporate entities involved in the rural development in the country.

Abstract

Assessment of quality and freshness of broodlac produced by the Indian lac insect Kerria lacca (Kerr) is an important parameter in its pricing. The present study provides an assessment of broodlac quality with 25, 50, 75 and 100% of lac encrustation harvested from summer (baisakhi), rainy (katki) on palas, winter (aghani) on ber, and summer season (jethwi) on kusum. The curve fitting model based on the rate of weight reduction can be used for prediction of freshness. Among the four lac crops, maximum rate of reduction was observed with summer kusmi (jethwi) and rangeeni (baisakhi) crops, and a good quality of broodlac was observed with katki crop on palas. Crawler emergence, stages of yellow spots and number of days for actual crawler emergence varied in different seasons. The present study differentiates the embryonic development into six stages with yellow spots through microscopic images. This reveals that the stage 1 coincides with earlier defined stage 2 and 3, and stage 2, 3, 4 and 5 are of stages 4, 5, 6 and 7 and 8, respectively.

Abstract

Field and laboratory experiments were carried out at the Assam Agricultural University, Jorhat during October, 2018 to April, 2019 to study the host plant preference of local lac insect Kerria chinensis on eight native plants of Assam viz., Flemingia semialata, F. strobilifera, Indigofera teysmannii, Ficus religiosa, Zizyphus mauritiana, Litchi chinensis, Hibiscus rosa-sinensis and Cajanus cajan. Results indicated that the maximum productivity of broodlac (0.31± 0.01kg) and longest lifecycle duration (171.92± 2.08 days) was recorded in F. semialata. Study on morphological parameters revealed that the girth of the bark of the plants possesses significant negative correlation with the settlement density of crawlers as well as production of lac. However, trichome density of the bark was found to possess positive but non-significant correlation with the settlement density of crawlers as well as production of lac.
