Effects of pendimethalin and different doses of ALS (Aceto lactate synthase) inhibitor on growth and yield of groundnut.

摘要

Field experiment on weed control studies in groundnut was carried out at the University Farm of Dr. Panjabrao Deshmukh Krishi Vidyapith. Akola during kharif 2002 to study the effects of pendimethalin and different doses of ALS (Aceto lactate 'synthase) inhibitor herbicide on growth and yield of groundnut. Weed free check as well as two hoeings and two weedings at 20 and 40 days after sowing (DAS) recorded more height, dry matter accumulation of plant and dry pod yield. Among integrated treatments, application of ALS (Aceto lactate synthase) inhibitor@ 50, 62.5, 75 and 100 g a. i./ha at 5 DAS followed by 1 H+1 HW at 35 DAS as well as ALS inhibitor herbicide at 50 g a. i.+pendimethalin 250 g a. i./ha at 5 DAS followed by 1 H+1 HW at 35 DAS observed significantly more growth in dry matter accumulation and dry pod yield as compared to lonely application of herbicide pendimethalin.
