Production potentiality of crops after pigeonpea under different tillage systems during summer in upper Krishna command area

L.N. Huggi, S.B. Kalaghatagi

Abstract


A field experiment was conducted at Agricultural Research Station, Almel (Northern Dry Zone of Karnataka) on medium deep black soil during summer-2015 to assess the performance of different crops under two tillage practicesafter harvest of pigeonpea during summer season. The treatments consisted of two tillage practices (zero tillage and minimum tillage) in main plots and different crops in sub-plots (4 pulses-greengram, cowpea, bengalgram and blackgram. 2 oil seeds- sesame and sunflower and a cereal- maize). Among two tillage practices, higher growth parameters like plant height, number of leaves, leaf area index, dry matter accumulation in leaves (g), dry matter accumulation in stem (g), total dry matter accumulation in plant (g) and test weight (g) (average of seven crops 87.31, 26.60, 1.11, 6.81, 15.54, 22.30 and 9.21 respectively) were recorded under zero tillage due to more moisture retention in soil as a result of lesser losses through evaporation and higher microbial activity as compared to minimum tillage. Among interactions, significantly higher grain yield was recorded by maize crop grown under zero tillage (3350 kg ha-1). Net returns were higher in blackgram crop grown under zero tillage (Rs. 91530 ha-1) and significantly higher benefit cost ratio was recorded under blackgram crop grown under minimum tillage (3.02).
