Title : Techno-performance of laser land leveller under various cultivation methods with suitable weed management regimes on growth of rice

Abstract :

Agriculture land levelling plays a key role because undulating topography of the fields has a major impact on the germination, water movement, water saving, weed growth and crop yields. Management of critical components such as land, water and weeds in agriculture has become a challenging task for many reasons. In rainfed and irrigated agriculture, land development plays a key role because of undulating topography of the soil surface. The study was conducted during Kharif 2021 to evaluate the performance of laser land leveller with various cultivation methods and weed management practices in rice at Tamil Nadu Agricultural University, Tamil Nadu, India. Plant height, number of tillers hill-1, Dry matter production were found to be higher in machine transplanted rice compared to conventional transplanting among cultivation methods. Amidst weed management practices Pyrazosulfuron + Pretilachlor (10 kg/ha) as pre emergence at 3 DAS/DAT fb Bispyripac sodium (25 g a.i/ha) as early post emergence application at 15 DAS/DAT over unweeded control. The results from this study confirmed that, machine transplanted rice with application of herbicide, Pyrazosulfuron + Pretilachlor (10 kg/ha) as pre emergence at 3 DAS/DAT fb Bispyripac sodium (25 g a.i/ha) as early post emergence application at 15 DAS/DAT in laser levelled land had better crop stand and growth thus resulting in lesser weed infestations.
