Mulberry is an important perennial crop grown primarily for foliage to rear the silkworm Bombyx mori L. for the production of cocoons. Among many other constituents, moisture content in mulberry leaf and its retention for longer durations play an important role in the successful production ofcocoons. The study conducted on seven mulberry genotypes growing as trees under rain fed conditions in Kashmir showed that the genotypes differ in the leaf moisture and its retention, with Goshoerami registering the maximum values. The moisture retention capacity after six hours and 12 hours of harvest in spring and early autumn was also significantly higher in Goshoerami .This may be due to more thickness of upper cuticle cum epidermis, stomata of smaller dimensions and more thickness of leaf.

The sustained production of quality cocoons is adversely affected due to the scare use of chemical fertilizer in mulberry cultivation by small and marginal sericultural farmers, mainly due to the escalating prices and non-availability in appropriate time. The required quantity of NPK nutrients for mulberry was supplemented through locally available different organic sources viz., farm yard manure (FYM), seri-compost, poultry manure, neem cake, green manure, bio-inoculants (Azotobacter biofcrtilizcr, vesicular arbuscular mycorrhiza (VAM), rock phosphate and phosphate solubilizing bacterial biofertilizer (PSB)). The nutritional status of mulberry leaf produced through organic cultivation is on par with that of leaf produced in the chemical fertilizer based farming as the results showed the leaf NPK, chlorophyll, carbohydrate and protein contents from the organic treatment ar con par with that of control. Similarly, the bioassay studies also revealed that there is no compromise in the quality of cocoon production as cocoon parameters did not showed any statistical significant difference between treatments and control. Thus, the present study confirms that by adopting absolute organic farming in muiberry cultivation, it is possible to produce quality mulberry leaf suitable for silkworm rearing which in turn produces quality cocoons.
