Abstract

A field experiment entitiled “Weed management in chickpea (Cicer arietinum L.) under different tillage practices in trans-gangetic plain region” was conducted for two consecutive Rabi seasons of 2022-23 and 2023-24 at Research Farm of Agricultural Research Station, Sriganganagar, Swami Keshwanand Rajasthan Agricultural University, Bikaner. The experiment consisted of twenty eight treatment combinations comprising of four different tillage practices (zero, minimum, conventional and deep tillage) and seven different weed control measures (weed free, weedy check, pendimethalin 750 g/ha PPI, pendimethalin 750 g/ha PE, pendimethalin + imazethapyr 800 g/ha PE, diclosulam 25 g/ha PE and flumioxazin 75 g/ha PE). The experiment was laid out in split plot design with three replications. Chickpea variety GNG-1581 was sown at 30 cm row spacing using 60 kg/ha seed rate. The results of experiment showed that the highest net returns (`120806/ha) with B:C ratio of 3.42 was obtained in deep tillage over zero and minimum tillage. However, it was at par with conventional tillage and B:C Ratio (4.04) and net return (`130879/ha) was also higher in pendimethalin + imazethapyr 800 g/ha PE. The organic carbon, available nitrogen, phosphorus and potassium content of soil after harvest of chickpea crop was not affected significantly due to different tillage practices and weed control measures

Keywords

Net return, deep tillage, zero tillage, minimum tillage, pendimethalin

Conclusion

Based on the results of two year experimentation, it may be inferred that the deep tillage practice and pendimethalin + imazethapyr 800 g/ha PE gave significantly higher net returns and B:C ratio of chickpea. The organic carbon, available nitrogen, phosphorus and potassium content of soil after harvest of chickpea crop was not affected significantly due to different tillage practices and weed control measures
