Abstract

A field experiment was conducted in mound plantations of Dalbergia sissoo and Eucalyptus camaldulensis on water logged-sodic site. Experimental site was poor in soil nutrients (N, P and K), experiencing waterlogging for the period of 100 to 150 days in a year. Experiment consisted five treatments viz. (1) control, (2) 50 g urea, (3) 50 g each of urea and single super phosphate, (4) 50 g each of urea, single super phosphate and muriate of potash and (5) 5 g each of urea, single usper phosphate, muriate of potash and 10 g of zinc suilphate per plant in Randomized Block Design with three replications. Species did not respond for application of single super phosphate. Application of urea and muriate of potash in Dalbergia sissoo resulted for insignificant higher survival and heigbht of plants. Eucalyptus camaldulensis showed significantly higher height from one year to three years of fertilizer application but level of resonse declined with the increase of plant age. Effect of fertilizer application for increasing volume index was, however, increasing.

Abstract

A field experiment was conducted at Uppardaha village in Allahabad District of Uttar Pradesh , India to compare response of organic and fertilizer source of nutrients to Terminalia arjuna , planted on mound in waterlogged sodic soil. Four treatments applied with and without 10.0 g plant. , BHC were (i) Control , (ii) 2.0 kg plant^-1 farm yard manure , (iii) 50 g plant^-1 each of NPK through urea , single superphosphate and muriate of potash and (iv) farm yard manure plus NPK as treatment 2&3 , respectively. Experiment was conducted following Randomised Block Design in triplicate , Comparison of plant height recorded twice in a year uuder different treatments showed that farmyard manure had no response up to six months , started to maximize height after one year and resulted for significantly higher height after two years. Nutrients applied through urea , single super phosphate and muriate of potash resulted promising effect in the initial stage of growth but slowed down afterwards. After two and half years of treatment , maximum biomass was recorded in farmyard manure treated plants , which was followed by plants receiving farmyard manure plus fertilizers and fertilizers alone. Plants treated with farmyard manure showed maximum and control showed the minimum CBH and survival in plants. Application of BHC , though , increased survival and height of plants but difference in BHC treated and untreated plant was insignificant.

Abstract

The nature and properties of the soils supporting Cryptomeria japonica in Darjeelling Himalayan Region were studied. The soils are acidic and contain high organic matter. The growth parameters are inversely related to the p^H and organic matter of the soils while height of plants and basal area of tbe species are positively correlated with C.E.C., exch. Ca⁺²,Mg⁺², K⁺ and available phosphorus. Total nitrogen contents of the soils are correlated positively with G.B.H. and basal area but negatively with the heights of the plants. Ranges of some of the attributes suitable for the growth of the species under more or less similar climatic conditions are assessed.

Abstract

Properties of termite (Odontotormes obesus) galleries developed on the stem of different living plants and termite mounds of the area Were compared. The study revealed that galleries. Contained greater concentration of calcium, magnesium and potassium than the mounds suggesting that the activities of termite, during gallery formation enhanced the nutrient status of the medium. The present study shows that the enhanced nutrients were derived from the bark of the plants used by termite as food and concentrations of the nutrients in the galleries depended both on the concentration of nutrients in the bark and on the amount of bark used as termite food.

Abstract

While various methods are available for collection of soil and vegetation data for further processing, no information is available from South Indian Forest, on the intensity of sampling for their survey, classification and mapping. An area of about 9000 ha in Coimbatore forest division was surveyed and both soil and vegetation data were collected at varying grid distances. The data were grouped, classified and mapped. Chi-square value of heterogeneity increased when the grid length was increased across the contour than along the contour. Considering the time and cost involved in survey, analysis of samples, processing of data and preparation of report, by compromising with accuracy, grid distance of 2km along the contour and 1 km across the contour may be used for forest soil and vegetation survey, classification and mapping.

Abstract

Investigation on the soil properties of the darjeeling Forest Division(W.B.) was carried out to see the changes due to different forest vegetations (Pinus patula, Cryptomeria japonica, tectona grandis, Shorea robusta and mixed broad leaf species). Highest content of organic matter and lowest soil pH were noticed in the site of C. japonica plantation; calcium content was maximum in teak(Tectona grandis) area. The solls under C. japonica had minimum total bases nad teak the maximum and more than half of the total bases in teak area was contributed by calcium. Mixed vegetations reflected best performance on soil properties among the plantations undertaken in the present investigation. Results showed that vegetational cover affects the soil properties and it is suggested that in order to maintain natural ecological balance and avoid drastic changes in soil properties, mixed plantation should be prefferred to pure plantation.

Abstract

Biomass production of different components (ischolar_main, stem, twig and leaf) of one year old Eucalyptus grandis due to different doses of urea and superphosphate application at Minmutti, Kerala, was assessed. Application of nitrogen and phosphorus increased biomass production of all tree components. Though, response was greater due to urea appliclltion than superphosphate application, combined application of N and P increased biomass production of all plant parts tremendously. Similar to biomass production fertilizer use efficiency was also better due to N and P application alone or in combination. Considering biomass production and fertilizer use efficieney, the treatment receiving 75 g urea along witb 73 g superphosphate found to be the most efficient treatment.
