Effect of panchagavya on quality, nutrient content and nutrient uptake of organic blackgram [Vigna mungo (L.) Hepper]

A field experiment was conducted at the instructional farm of Rajasthan College of Agriculture, Udaipur, Rajasthan during kharif season of 2015 to study the effect of panchagavya on yield, quality, nutrient content and nutrient uptake of organic blackgram. A significant increase in seed yield, straw yield, biological yield and maximum nitrogen, phosphorus, potassium, sulphur, zinc and iron content in seed and straw and their uptake and protein content in seed was observed with the application of panchagavya 4% over control, panchagavya 2%, panchagavya 6%, panchagavya 8%, panchagavya 10% and indigenous panchagavya 2%. Application of panchagavya at branching + flowering stages significantly increased seed yield, straw yield, biological yield and maximum nitrogen, phosphorus, potassium, sulphur, zinc and iron content in seed and straw and their uptake and protein content in seed of blackgram over the application of panchagavya at branching alone and flowering stage alone.
