Abstract

The present study deals with the computation of compositional pattern diversity in Kalsa watershed, Kumaun Himalaya. Compositional pattern diversity, which is a measure of complexity of the landscape, has been measured as mosaic diversity using affinity analysis. A total of four forest types were classified using satellite remote sensing data which include temperate broadleaf forest, temperate conifer forest, pine forest and degraded forest. The results of affinity analysis showed maximum value (6.53) of mosaic diversity for temperate conifer forest followed by the temperate broadleaf forest (6.49), degraded forest (5.72) and pine forest (5.58). Pooled data from all the forest types when was taken for stratawise analysis showed maximum value (4.63) for herb layer followed by the shrub layer (3.51) and tree layer (2.50). High values (<3) of mosaic diversity indicated the presence of many underlying ecological gradients controlling the vegetation and high sensitivity of shrub and herb layer towards landscape complexity.

Abstract

Wheat (Triticum aestivum L.) is one of the most important rabi (winter ) crops being grown with association of boundary plantations of poplar. Growth environment of wheat may be modified and differ from that of pure agricultural system due to shading, competition for nutrients as well as moisture when grown with association of poplar. The aim of this study was to determine the effect of poplar (Populus deltoides M.) boundary plantations on growth and yield of wheat (Triticum aestivum L.) under irrigated condition. The adverse effect of poplar trees on wheat growth increased with advancement in tree age. No significant adverse effect was noticed on wheat grain yield when grown with association of 3 year old boundary plantations of poplar. Whereas, decline of 15.5% was recorded up to a distance of 3 m from the tree base due to 4 year old plantation. Among growth parameters, plant population of wheat suffered heavily up to a distance of 9m. However, relative proportion of effective tillers, dry matter production, 1000 grain weight, straw yield and leaf area index increased significantly between 3-9m distance from tree line, depending upon the age of plantation. Thus, it is inferred that the age of trees was found one of the important factors which influenced both growth and yield of wheat grown adjacent to the tree line.

Abstract

Poplar plantations, grown in association with wheat, are getting popularized with the farmers in India. Poplar is a deciduous tree and its leaf fall occurs before wheat sowing. Its leaves are buried in field during field preparations. Therefore, a pot study was conducted for two years to study the changes in growth parameters and yield of wheat due to presence of Poplar leaf litter (no litter; 10 g pot^-1 and 15 g pot^-1). Further, two levels of fertilizers (M_n , no fertilizer and M₁, application of full recommended dose of fertilizer, @ 120, 60 and 40 kg ha^-1 N,P,K, respectively) were kept to see the influence of mulch on the performance of wheat in combination with nutrients. Leaf litter used as a source of mulch during first and second year were from the 3 and 4 year old plantation, respectively. Growth and yield response of wheat to fertilizer were significantly superior than those of without fertilizer. Grain yield increased significantly when 15 g pot^-l of 3 year old Poplar leaves were incorporated into soil. On the other hand, straw yield increased significantly when low dose (l0g pot^-l) of 3 year old Poplar leaf was used. Better growth and higher grain yield were recorded when leaf litter was incorporated in combination with fertilizer and as well as with the higher doses of leaves. Results of pot experiment revealed that better growth and higher grain yield can be obtained by incorporating the Poplar leaf in combination with chemical fertilizers.

Abstract

Poplar with high productivity in 6-12 years rotation is being preferred, particularly as boundary plantations, in various agroforestry systems in northern part of India. A quantitative approach is an important step in the quest for a better understanding of the complex mechanisms of tree-crop interaction, which should offer scientific basis for designing more productive and sustainable agroforestry systems. This paper reports on the quantitative estimations of various interactions occurring at the tree line/crop interface of Poplar and wheat grown on irrigated alluvial soil in Western U.P. No significant adverse effect was noticed on wheat crop when grown with association of 3 year old boundary plantation of Poplar. However, a significant decline of 15.5 per cent was recorded only up to a distance of 3 m from the tree base due to 4 year old plantation. Water use of the system increased upto 6 m from the tree line which caused moisture stress to the wheat crop. At the same time boundary plantation of Poplar had favourable effect on the micro-climate which improved the status of soil moisture between 6-9 m distance and increased the water use efficiency. Competition for natural resources was reduced between weeds and wheat due to reduction in weed population and biomass in the system. Litter production averaged 1103 kg ha^-1 in 3 and 4 year old plantation and this returned 12,2.5,8,21.3 and 8.6 kg ha^-1 ofN, P, K, Ca and Mg to the soil. Addition of leaflitter near the tree line tended to change the physico-chemical properties of the soil.

Abstract

Field study was carried out to assess the leaf litter production and quantity of nutrients returned to the soil through litter fall of Populus deltoides (boundary plantation) based agroforestry system under irrigated condition. Litter fall was restricted upto a distance of 9m from the tree line and total amount of 913.8 and 1291.8 kg ha^-1 was estimated with 3 and 4 year old plantation, respectively. Maximum amount of leaf fall (46-57%) was collected from 0-3 m distance and reduced with increase in distance from tree line .. On an average, 557.4, 367.6 and 177.5 kg ha^-1 leaflitter was collected between 0-3, 3-6 and 6-9m distance, respectively. Considerable amount of nutrients was recycled to the soil through leaf fall. The return of nutrients through leaf litter into the soil decreased in the order ofCa > N > Mg> K > P. It was estimated that highest calcium of 18.3-24.3 kg ha.1 , followed by nitrogen of 11.2-12.5 kg ha^-l, magnesium of 7.8-10.0 kg ha^-1 , potassium of 6.9-8.9 kg ha^-1 , and phosphorus of 2.45-2.59 kg ha^-1, was added/returned to the soil during winter leaf fall of Populus deltoides.

Abstract

Studies regarding the floristic diversity and phytogeographical affinities of Jhalawar district tree flora reveal that out of 182 upper storey cover species recorded in the area, 31 species were planted (cultivated) for various economic uses, while 151 species were found naturalized in the the area, 29 of the naturalized species, were also planted for edible fruits or as avenue trees or for timber in different parts of the district. 27 species were found growing near streams, rivers or in low lying areas, while 88 species were recorded in deciduous forests&hills tracts. On the contrary 37 upper storey cover species were observed in open, dry, gravelly and in other xeric conditions e.g. scrubby vegetations. 89 tree species were microphanerophytes, (Mi) 69 species demarcated as mesophanerophytes (Ms) and only 24 remaining species were reported to be megaphanerophytes (Mg) (large sized trees). Phenological studies about tree-flora indicated that flowering of 30 species initiated in rainy season, 70 species bloom in summer, 8 species flower round the year, while maximum, 74 species are laden with flowers in winter season, possibly due to photoperiodic temperature, humidity and light intensity requirements of these species. Possible reasons and plausible assumptions about the habit, habitat and physiognomy diversities have also been described. Exceptional presence of some species e.g. Adansonia digitata, (Tropical Africa), Prosopis cineraria (Arid zone species), Adina cordifolia and Mangifera indica (Subtropical forests), add new dimensions to the floristic diversity of the area as well as this may be due to the phytogeographical location of the locality which represents 1 : 1 ratio between eastern and western elements.

Appendicitis a well known intestinal disease now a days is caused by appendicular infection and inflammation. In modern allopathic system there is no perfect treatment of this disease except appendectomy. However, this disease is completely cured by the Bhil tribals of Jhalawar district (South-East Rajasthan), by the local application of plant paste of Ocimum americanum L. (Lamiaceae) on patient's abdomen. No further abdominal surgery of the patient is required in this particular mode of treatment. It is expected that after further researches this plant might prove a great source of safe, cheap and effective drug for the cure of appendicitis and will be a great asset for the welfare of human society.

Abstract

Objective: To design and develop cost effective solar panel and autoclave for steam sterilization of medical equipment and disposal of hospital waste using solar energy. Methods/Analysis: An attempt has been made to design and develop an autoclave to sterilize the medical instruments by generating the steam in a vessel using the environment friendly solar energy. For this purpose, the solar parabolic trough for generating steam and a vessel which can be used as an autoclave for steam sterilization by subjecting the equipment and tools and medical waste to steam at 1210 C for 15 minutes have been designed using low cost material. Findings: The vessel reached the maximum temperature of 1320 C and pressure 15 PSI for more than 15 minutes. The desired outcome of temperature and pressure required for sterilization was achieved with 3 litre aluminium pressure vessel after making modifications in its safety valve. The combined cost of all the materials used in fabrication of parabolic trough and its trolley and modification of the vessel for conducting all the experiments is Rs.30,000/- approximately. The design can be further improved by identifying the optimum size of the vessel and modifying the safety valve. Novelty/Improvement: An ordinary pressure cooker has been converted into an autoclave and the solar parabolic trough developed is also of low cost. The whole set up designed is of very low cost and can be effectively used in remote areas.

Abstract

Soil degradation induced by erosion represents a major threat to food production and ecosystem service globally, and in India more than 80 Mha have been impacted. In the light of the serious threat, there is a pressing need for a systematic nationwide assessment of land degradation due to erosion. We discuss the potential for using caesium-137 and lead-210 tracers to address this need and the next steps to realizing nationwide implementation.

Abstract

Spare parts management is integral to successful and cost-effective maintenance practice in integrated steel plants. As the maintenance philosophy is gradually transformed into reliability based maintenance, the reliability and predictability of parts’ life gains higher significance. Reliability of reclamation by proactive techniques for spare parts is viewed in this context, along with the importance of maintenance cost reduction. This paper deals with the focus areas of cost reduction in spare parts management in maintenance of steel plants with particular reference to reclamation and reconditioning practices. Field experience at Tata Steel proves the gains achieved in downtime and replacement costs. These are explained on the basis of actual work done at various plant locations.
