Four elite mulberry varieties viz. S1, K2, C763 and C776 were evaluated under partially irrigated conditions at five fertiHzer levels, using spilt plot design, on the basis of vaious, growth parameters like extension growth, branching, no. of leaves, leaf area, hundered leaf weight, weight of 100 sq em laminar area, total photosynthetic area, total fresh leaf yield and moisture content of leaf. S1 variety was found to be the best mullberry variety from sericultire view point and NPK @ 150:50:50 kg/ha/yr in combination of FYM @ 10 MT/fia/yr was fOYnd to be the most cost, effective fertilizer level under partially irrigated coooitions. Role of different growth attribute in bringing out qualitative and quantitative changes in leaf production is also discussed.
