Correlation and path analysis studies in recombinant inbred lines (F8) of Langulmota/Sambamahsuri derivatives

Abstract

Keeping in view of hazardous effect of herbicides a trial has been conducted to assess the performance of some specific weeding implements in rabi maize cultivation by KVK, Saharsa in two consecutive years 2017-18 and 2018-19. Different crop specific weeding implements had been kept under trial from time to time in rice, soybean and vegetable crops and it had been found that application of a weeding tool for interculturing and weeding operation also provided better aeration to crop roots, enhanced organic contents of the cultivable area along with combating the hazardous situation due to application of herbicides. A twin wheel hoe and a grubber have been kept under assessment with the use of a spade, a common tool for interculturing operation among farming communities. The field capacity of the twin wheel hoe has found the highest among the implements under trial. The B:C ratio (2.35) and the yield (95.7 q/ha) have also been observed the highest in the plots where the twin wheel hoe has been applied for the purpose.
