Impact of Tillage Practices and Chickpea Varieties on Nutrient Uptake in a Mungbean-Chickpea Cropping System

Aims: To study the effect of tillage management on nutrient concentration and uptake of different varieties in chickpea (Cicer arietinum L.) under mungbean-chickpea crop sequence Study Design: strip plot design. Place and Duration of Study: Pulses Research Unit, Washim Road, Dr. Panjabrao Deshmukh Krishi Vidyapeeth (Dr. PDKV), Akola, Maharashtra, India during the rabi season of 2019-20. Methodology: There were four tillage practices and two varieties (eight treatments) replicated five times. Main plot treatments include tillage practices for chickpea crop and Sub plot treatments includes two varieties of chickpea, JAKI-9218 and PDKV-Kanak (AKG-1303). Results: There were four tillage practices and two varieties (eight treatments) replicated five times. The findings showed that the effect of different tillage treatments and varieties on the nitrogen (% N), phosphorus (% P) and potassium (% K) content in seed and straw of chickpea crop was found non-significant. Nutrient uptake (kg/ha) in seed and straw and total uptake (kg/ha) of nutrient by crop was higher with treatment tractor drawn cultivator + harrowing + sowing + one hoeing + one hand weeding (T1). The variety JAKI-9218 recorded significantly greater nutrient uptake than the PDKV-Kanak. Conclusion: Nutrient concentration (%) and uptake (kg/ha) in seed and straw and total uptake (kg/ha) of nutrient by crop was higher with treatment tractor drawn cultivator + harrowing + sowing + one hoeing + one hand weeding and JAKI-9218.
