Abstract

Clusterbean is one of the most important crop of arid and semi-arid region of India. It is mainly grown for vegetable, manure, fodder and seed purpose. Seeds of clusterbean contain galactomann (stored in endosperm) which has industrial uses, thus making it the major cash earner crop. Various biotic and abiotic stresses affects the crop during its growth stages. Among biotic stresses, weeds are the major one affecting the crop growth and yield. Due to initial slow growth of the clusterbean intense crop-weed competition takes place upto 20-30 DAS and if weeds are not managed properly there will be a severe yield reduction. Under Haryana conditions only manual weeding is recommended which is time consuming and expensive hence there is need to exploit other methods of weed control. Therefore, present study was conducted to study the effect of mechanical methods of weed management on growth, yield and economics of clusterbean.

A field experiment was conducted during kharif season 2018 to study the effect of mechanized weed management practices on growth, yield and economics of clusterbean at Regional Research Station, Bawal (Rewari), CCS Haryana Agricultural University, Hisar. Experiment was performed in randomized block design with ten treatments and three replication.

It was found that among various weed management practices, two mechanized weeding with power weeder at 20 DAS and 35 DAS under 60 cm row spacing resulted in significantly higher plant height, leaf area index, dry matter accumulation, seed yield and its attributes in comparison to other treatments and it was statistically at par with mechanized weeding at 20 DAS and 35 DAS with tractor drawn cultivator. The weeding with tractor drawn cultivator was found to be most economical with maximum net returns (Rs. 36076 ha-1) and B:C (2.37) in comparison to other treatments followed by weeding with power weeder that fetched net return of Rs. 35868 ha-1 with B:C of 2.25. Therefore, two times interculture with power weeder or tractor drawn cultivator found beneficial and economical for farmers.
