Response of Green Gram [Vigna radiata (L.) Wilczek] to Different Weed Management Practices

Abstract

Background: Green gram is an important pulse crop known for its nutritive values as a rich source of protein and high culinary application in Indian dietary system. However, like any other crop, it faces the challenge of weed competition, which can significantly reduce its yield and quality. The objective of this study was to determine the best suitable weed management practices for green gram. Methods: Field experiment was conducted during summer season of 2021 at School of Agricultural Sciences, Nagaland University, Medziphema Campus. There were seven weed management treatments and one treatment kept as control. All treatments were replicated thrice. Result: Hand weeding at 20 and 40DAS showed greater weed control and recorded higher values in growth and yield and showed at par values with other weed management practices pre-emergence application of pendimethalin fb hand weeding at 20 DAS, Pendimethalin @ 0.75 kg ha-1 (PE) fb Rice straw mulching @ 5 t ha-1, Imazethapyr @ 0.5 kg ha-1 (PoE) at 15 DAS fb Quizalofop p-ethyl @ 0.15 kg ha-1 (PoE) at 30 DAS and Pendimethalin @ 0.75 kg ha-1 (PE) fb Quizalofop p-ethyl @ 0.15 kg ha-1 (PoE) at 30 DAS. However, the use of only rice straw could not perform better. This indicates the advantages of integration of weed management practices. With hand weeding a laborious task concerning in large field condition, other integration of weed management will serve a viable option for profitable weed management in green gram.
