A study on effect of nutrient management practices on soil microbial counts and economics in chickpea in Karnataka state

Abstract

A field experiment was conducted at Krishi Vignana Kendra, Kalaburagi, University of Agricultural Sciences, Raichur during rabi 2015-16. To study the “Nutrient management in chickpea (Cicer arietinum L.) in black soil under rainfed situation”. The study objective was to assess chemical properties also apart from nutrient management. The findings reveal that, significant enhancement in the soil microorganism’s viz., bacteria, fungi and actinomycetes noticed at harvest stages of chickpea. The significant increase in microbial counts was observed with the addition of organic manures in combination with fermented liquid organic manure. Among all the treatments at harvest, significantly higher dehydrogenase activity was recorded in FYM @ 5 t ha-1 + VC @ 2.5 t ha-1 + Jeevamrutha (13.11) which was due application of organic manure. Further, regaring economics, minimum cost of cultivation was recorded in (T1) during the study period.
