Abstract:
The present investigation entitled “Quantification of soil dehydrogenase enzyme activities in long-term fertilizer experiment under rice-wheat cropping system on Vertisol” during the kharif and rabi seasons of 2018-19 and 2019-20 at research farm of college of Agriculture, Indira Gandhi Krishi Vishwavidhyalaya, Raipur, Chhattisgarh. The objective of the study were to quantify the microbial respiratory enzyme under inorganic and integrated nutrient management practices. The experiment was designed with Randomized Block Design. The ten treatments of experiment are control, 50% NPK, 100% NPK, 150% NPK, 100% NPK+Zn, 100% NP-K, 100% N-PK, 100% NPK+FYM (5 t ha^-1), 50% NPK+BGA (10 kg ha^-1), 50% NPK+GM (Sunhemp). The above treatments were randomized with three replications. The soil type was Vertisol, also known as kanhar in the local language. It can be concluded from the study that the microbial respiratory enzyme under inorganic and integrated nutrient management practices was observed highest in 100% NPK + FYM, as compared to others as well as absolute control.
