Study on the availability of plant nutrients in Panchagavya added bulky organic manures
The experiment was conducted during December-2014 to May-2015 at the laboratory of IRTDM Faculty Centre, Ramakrishna Mission Vivekananda University, Morabadi, Ranchi-834008 on “Study on the availability of plant nutrients in Panchagavya added bulky organic manures”. Commonly available bulky organic manures like FYM, Vermicompost and Poultry manure and their combinations were selected for the study. Addition of Panchagavya to the manures enhanced their nutrient composition in terms of available NPK, OC and microbial population. The treatments combinations were: T1= FYM (600 g) + Panchagavya (550 ml); T2= Vermicompost (600 g) + Panchagavya (350 ml); T3 = Poultry litter (600 g ) + Panchagavya (490 ml); T4 = FYM (300 g) + Vermicompost (300 g) + Panchagavya (460 ml); T5 =FYM (300 g) + Poultry litter (300 g) + Panchagavya (520 ml); T6 =Vermicompost (300 g) + Poultry litter (300 g) + Panchagavya (440 ml); T7= Vermicompost (200 g) + Poultry litter (200 g) + FYM (200 g) + Panchagavya (740 ml) [Panchagavya (25%) solution was used and the quantification of this liquid manure was based on the maximum absorption capacity of the treatment materials i.e. bulky organic manures]. From the experiment, it was revealed that T6 (vermicompost + poultry litter + Panchagavya) was the best treatment among all other treatments when nutritional status of the treatment in respect of the plant nutrient contents was taken into consideration. On the contrary, T6 and T3 (poultry litter + Panchagavya ) had emerged as best treatments in terms of longevity or shelf-life viewpoint with desirable levels of almost all studied parameters that remain either unchanged or increased for comparatively longer periods after addition of Panchagavya as per the requirement of the treatment combinations.
