Abstract
Non-judicious application of various fertilizers to the plants adversely affects not only the soil fertility but also micro, macro flora and fauna. Though Mulberry occupies only a small area of 0.26% of the total cultivated area in the country, but the big cause of worry is that the use of fertilizers and chemicals greatly affect the soil and water resources. It can be overcome by organic farming. The study conducted at Regional Sericultural Research Station, Sahaspur, Dehra Dun by adopting different organics in Mulberry cultivation has shown that the application of organics, leaf quality can be improved. The leaf produced by application of different organics was found improved total soluble Protein (14.90%), fiber (10.80%) against 13.98% and 10, 34% in control besides enhancement in leaf yield from 18.99t/h/yr in treatment plot as against 8.26 t/h/yr in control. The cocoon quality was also improved by feeding the leaves to silkworms produced by application of organics in comparison to control. The silk ratio percentage was recorded higher 20.22% in tree in comparison to 18.54% in controls respectively. It was also observed that the nutrient status of the soil was improved (organic C% 0.82 % from 0.72%; P 62.40 kg/ha from 38.08 kg/h; K 460 kg/h from 448.0kg/h) after microbial colonization and continuous application of organics. The silk yarn quality was also improved by recording more non-breakable filament length (NBFL) 850 m (757-1073 m) as against 750 m (629-1037m) in control. This package of practice is eco-friendly and leaf yield recorded also increased, hence it is recommended for field.
