ONGOING PROJECTS :
PPS 3346 :Studies on
the effect of sulphur on mulberry growth, yield, nutrient uptake and soil
fertility in the Gangetic plains of
Location: CSR & TI, Berhampore
Milestone: To work out effective dose and form of sulphur to enhance the mulberry leaf yield economically in a sulphur deficient soil and also to improve the soil fertility, principally in terms of available sulphur content.
PPS3347:
Evaluation of soil fertility for sustained production of quality mulberry leaf
in
Location: CSR & TI, Berhampore
Milestone: To identify the specific nutrient input package in terms of sustaining leaf productivity of mulberry over the years and maintaining the soil quality as well.
CONCLUDED PROJECTS :
01. Studies on nutritional composition of mulberry leaves.
Result: Nutritional composition of leaves of various varieties has been studied.
02. Isolation and identification of different compounds from mulberry.
Result: Some heterocyclic compounds were isolated and identified.
03. Studies
on the effect of CAN on mulberry at Kishanganj (
Result: It was observed that CAN performed better over urea.
04. Studies on by-product utilization.
Result : Few materials have been isolated from pupae wastes and faeces.
05. Comparative study of different nitrogenous fertilizers with Sufala on leaf yield and nutritive value of mulberry leaf.
Result: Highest dose of nitrogen (300 kg/ha/yr) with Sufala and Urea performed best.
06. Effect of different doses of Ammonium sulphate and lime on soil composition, leaf yield and nutritive value of mulberry leaf.
Result : 900 kg N/ha/yr along with 1.0 mt lime/ha/yr showed the best result.
MS1: Studies on NPK budgeting for known soil types.
Soil types:
· Gangetic alluvial soil
· Red-laterite-gravelly soil
Result: Ready reckoners for nitrogen fertilizer application for irrigated Gangetic alluvial soil and rain-fed Red-laterite-gravelly soil have been evolved.
PPS001: Studies
on the problematic soils of
Regions:
· Tarai region
· Red-laterite-gravelly region
Result:
Recommendation for doses of lime application for the acid soils of Tarai and
Red-laterite- gravelly regions of
