Abstract

                                The effect of mineral deficiency on mulberry ntant was studied under pot culture with Kanva-2 mulberry variety under different deficient nutrient conditions. The leaves were chemically analysed and discussed. To test the quality of leaves, a feeding experiment was conducted by feeding the hybrid worm. LX NB,D, from stage upto cocoon formation. The larval, cocoon and silk characters revealed that deficiency in N P and K affected the growth and nutrient content of mulberry leaves which in turn affected the growth and economic characters of silk worm. Among the three elements, p deficiency affected the cocoon characters and silk characters very badly, because deficiency in 'P affected the up- take of other elements in mulberry leaves.
