Study on the nutrient enhancement of kunapajala added bulky organic manures in terms of their shelf-life
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 the Nutrient Enhancement of Kunapajala added Bulky Organic Manures in terms of their Shelf-life. Commonly available bulky organic manures- FYM, Vermicompost and Poultry manure and their combinations were selected for the study. Addition of Kunapajala to the manures enhanced their nutrient composition in terms of available NPK in relation to the shelf-life. The treatments combinations were: T1= FYM (1 kg) + Kunapajala (900 ml); T2= Vermicompost (1 kg) + Kunapajala (1280 ml); T3 =Poultry litter (1 kg) + Kunapajala (1640 ml); T4 = FYM (500 g) + Vermicompost (500 g) + Kunapajala (1120 ml); T5 =FYM (500 g) + Poultry litter (500 g) + Kunapajala (1340 ml); T6 =Vermicompost (500 g) + Poultry litter (500 g) + Kunapajala (1456 ml); T7= Vermicompost (333.33 g) + Poultry litter (333.33 g) + FYM (333.33 g) +Kunapajala (1272 ml) and T8= Control [Kunapajnala (mother solution) only]. The quantification of Kunapajala was determined by the saturation points of the bulky organic manures used for the study in different treatments. From the experiment, it was revealed that T3 was the best treatment among all other treatments when nutritional status of the treatment in respect of the nutrient contents was taken into consideration. On the contrary, T6 (vermicompost + poultry litter + Kunapajala) and T3 (poultry litter + Kunapajala ) had emerged as best treatments in terms of longevity/shelf-life with desirable levels of almost all studied parameters that remain either unchanged or increased for longer periods (75-90 days) after preparation of Kunapajala as well as mixing with different bulky organic manures.
