Abstract:

Weed is a plant growing where it is not desired so weeds are ubiquitous. The vegetable fields are usually infested by a wide spectrum of broad and grassy weeds. Weeds compete with the crops for water, soil, nutrients, light, space and crop yields are significantly reduced as reported by several studies. The vegetable as well as agricultural crops are infested with a variety of weeds. Out of over 800 weeds documented in India, 80 are considered as serious and nearly 200 as major weeds. They also harbour many insect-pests and microorganisms. On an average weed extract two times more N and Ca and 25 per cent more potassium than the crop as observed in some studies. Reduction in economic yield of vegetables has been reported to be 6-82 per cent in potato, 25-30 per cent in peas, 70-80 per cent in carrot, 67 per cent in onion, 42-71 per cent in tomato and 61 per cent in cauliflower. Farmers usually have a various methods for weed control and their choice of control measures is closely controlled by economics. Although, herbicides were introduced to horticultural crops in India in 1960, hand tools and animal drawn equipment still remain important methods of weed control in vegetable crops. Conventional methods of weed control have become an expensive input in the cultivation of vegetable crops. Owing to high cost and non- availability of labour at proper time therefore, no single method of weed control is adequate and cost effective. However, integrated weed management is a systematic approach to minimize weed impacts and optimize the land use by the different weed management practices.
