Study on the nutrient contents of sasyagavya at fifteen days interval after mixing with different available bulky organic manures

The experiment was conducted during January-2014 to April-2014 at the laboratory of IRTDM faculty centre, Ramakrishna Mission Vivekananda University, Morabadi, Ranchi-834008 to study on the nutrient contents of sasyagavya at fifteen days interval by mixing with different available bulky organic manures. The treatments were prepared by utilizing different easily available organic manures like-FYM, vermicompost, poultry manure etc. after mixing with sasyagavya. The treatments are: T1 = Sasyagavya (420 ml) + FYM (500 g); T2 = Sasyagavya (640 ml) + Vermicompost (500 g); T3 = Sasyagavya (740 ml) + Poultry manure (500 g); T4 =Sasyagavya (500 ml) + [½ FYM (250 g) +½ Vermicompost (250 g)]; T5 = Sasyagavya (550 ml) + [½ FYM (250 g) +½ Poultry manure (250 g)]; T6 = Sasyagavya (666 ml) + [½ Vermicompost (250 g) + ½ Poultry manure (250 g)]; T7 = Sasyagavya (600 ml) + [⅓ FYM (166.66 g) + ⅓ Vermicompost (166.66 g) + ⅓ Poultry manure (166.66 g)] and T8 = Sasyagavya (mother solution) only. The quantity of Sasyagavya is based on the maximum absorption capacity of the used organic manures. Different parameters like available NPK, organic carbon, pH and EC as well as total microbial population were estimated at fortnight intervals. From the findings, T6 emerged as the best treatment in terms of nutrients content (available N, P, K and OC) and microbial population. The longevity study also emphasized the same treatment (T6) with their longer periods of nutrient retention capability.
