Project Title :Nutritional value of important varieties of mulberry.
Project Period :1967-1969
Objectives :To assess the comparative nutritional status of the different varieties of mulberry under Mysore soil and climate conditions.
Results/Recommendations :
· The crude protein content varies significantly in different varieties. The results confirm the earlier observations that the tender leaves at the top position of the plant contain the highest amounts of leaf moisture and crude protein content with the lowest amounts of minerals. The coarse leaves at the bottom contain the highest amount of minerals with lowest amounts of leaf moisture and crude protein contents.
· Tender leaves of Shimanouchi varieties contained the highest amount of crude protein (26.03%), Karyorosa and Kanva-2 (23.58 and 23.44%) were next in order. Medium leaves of local variety contained the maximum amount (22.92%) and Shimanouchi (20.0%), coarse leaves of local variety contained maximum amount of crude protein (22.53%), Rostelli (18.82%) and Kanva-2 (18.27%) came next in order.
· Maximum amount of total sugars was found in the tender leaves of Rostelli variety (14.77%) which was followed in order by local (14.20%) and Kosen (11.28%) Medium leaves of Tomieso contained (8.80%) while Karyorosa (8.43%) and Kanva-2 (7.7%) followed. Coarse leaves of Mizusawa contained higher amount of total sugars (13.93%) and Saniish and Tomieso (8.84% and 7.99%) were the I and III among the varieties studied.

Project Title :Co-ordinated chemical analysis and leaf harvests of different treatments under mulberry crash programme.
Personnel : Basavanna HM, Srinivasan KB, Kodandaram MS
Project Period :1970-1974
Objectives :Studying the comparative nutritional status of two varieties of mulberry i.e., local and Kanva-2 as influence by the nitrogen application and spacing.
Results/Recommendations :
Effect of maturity on chemical composition of mulberry leaf:
· The moisture content decreases from tender to coarse leaf.
· The crude protein decreases from tender to coarse leaf.
· The total sugar content decreases with maturity.
· Starch decreases with maturity.
· The total mineral content increases from tender to coarse.
Effect of variety on chemical composition:
· K2 variety leaf contains 1.16% more moisture than local variety of leaf.
· K2 is rich by 1.08% of total sugar over local variety.
· Local variety of mulberry leaf is rich in crude protein over K2
Effect of spacing on chemical composition: Leaf sample harvested from close spacing S2 (1½' x 3") is superior to the samples from wider spacing S0 (1½' x 1½') as the S2 (closer spacing) increases the moisture content by 0.46% over S0 (wider spacing) the crude protein by 1.01%. The total carbohydrate by 0.5% and closer spacing decreases the total mineral by 0.57%.
Effect of nitrogen application: N3 (Nitrogen applied at 900 kgs/ha/yr) fertilization decreases the mineral content of mulberry leaf by 1.44%.

Project Title :Improvement of leaf quality through fortification of mulberry leaves with Casein, Urea and Jaggery solutions.
Project Period :1970-71
Objectives :Better utilization of mulberry leaf by the silkworm and to find out the corresponding increase, if any in the larval weight and improvement of cocoon characters due to the feeding of fortified leaves.
Results/Recommendations :Except the larval weight, filament length and higher floss percentage, other characters were better in case of plain control when compared to casein or jaggery or urea solution treatment of leaves, considering the economics of application, fortification of the leaves with casein/jaggery/urea solution does not appear to be a suitable proposition as they did not improve the economic characters as compared to water treatment.

Personnel :Singhal BK, Chakraborti S
Project Period :1992-1997
Objectives :To study the physiological parameters of different mulberry genotypes.
Results/Recommendations :Among all the genotypes tested, Ascorbic acid content was found highest (1.358mg/g) in the genotypes S13, followed by S799.

Personnel : Sivarami Reddy N, Venugopal A, Naidu BVV
Project Period :1996-1997
Objectives : To study the leaf moisture retention capacity in some mulberry varieties and leaf preservation methods suitable to Andhra Pradesh.
Results/Recommendations :Leaf moisture varied among 3 mulberry varieties (S13, Local and K2) as also among 3 leaf types (tender, medium and coarse).

Personnel :Madhumala, Sarkar A
Project Period :1998-1999
Objectives :To find out the variability in SPAD chlorophyll meter values under different fertilizer stress including control and to find out the relationship between SPAD chlorophyll meter value and important biochemical and physiological characters which will be helpful in prediction of leaf yield and nutrient status of the farmers field.
