Personnel :Reddy MM, Sinha AK
Project Period :1993-1994
Objectives :To study the effect of split application of phosphatic fertilizers for production of quality mulberry leaf.
Results/Recommendations :
· Effect of split doses of phosphatic fetilizers on the mulberry leaf has been conducted in 6 trials. T6 i.e., NPK in five, split doses and foliar spray in two split doses (60kg/ha soil application + 30 kg/ha foliar and two split doses respectively) has resulted in the highest leaf yield and ‘P’ content among all treatments.
· Treatment T6 has given leaf yield 53.307 g/pot which is 48.06% higher than control T1 (36.002 g/pot). P content was significantly more in T6 than in other treatments. This indicates that for getting the optimum yield of mulberry leaf, application of phosphatic fertilizers is a must.
· Hence, it is suggested to apply phosphorus in five split doses instead of two doses for getting the optimum yield of quality mulberry leaf.

Project Title :Dissemination of dry land mulberry farming techniques and tree mulberry cultivation through participatory programme (PPA-3271)-Impact of in situ soil moisture conservation measures in farmers mulberry garden.
Personnel :Jayaram H, Mishra RK, Srikantaswamy K
Project Period :2004-2006
Objectives :To disseminate the soil moisture conservation practices among the sericultural farmers for improving the land productivity.
Results/Recommendations :Among the in situ soil moisture conservation techniques the conservation furrows with tied ridging brought out significant results. There was an improvement in the soil moisture (0-30 cm depth) in treated plot (16.30%) compared to combined (10.25%). An improvement in the leaf yield upto 12% was also observed in the field. The average leaf yield under treated plots was 14,500 kg/ha/yr as compared to control (12,800 kg/ha/yr).

Project Title :Effect of graded levels of phosphorus application on phosphorus uptake, mulberry leaf yield, quality and silkworm rearing-Effect of phosphorus and its deficiency on the quality of mulberry leaf and silkworm rearing.
Personnel :Munirathnam Reddy M, Subbuswamy MR, Vedavyasa K
Project Period :2004-2006
Objectives :To reschedule the phosphorus recommendation based on soil available phosphorus status and nutritional requirement for commercial rearing of silkworms.
Results/Recommendations :The field experiment was laid out under randomized block design with seven treatments and three replications. Soil analysis data after one year revealed pH-8.00, Electrical Conductivity-0.18 milli mhos/cm, Organic Carbon–0.55%, available phosphorus–34.54 kg/ha, available potassium–395 kg/ha and total phosphorus–1563 kg/ha. Five crops of first year were harvested and data revealed difference in yield among the treatments. Highest leaf yield 41790 kg/ha/yr was recorded in T5 (300N:150P:120K kg/ha/yr +20MT FYM) over the T1 37876 kg/ha/yr (300N:00P:120K kg/ha/yr + 20 MT FYM).
