Proper land use management

Soil forms an integral part of the ecosystem and at present the quality of a soil is defined not only in terms of its productive capacity, but also by taking the ecosystem into consideration. Consequently, when soil productivity has to be maximized, environmental effects must be given proper consideration. Thus the changes in soil quality caused by different types of land use must first be quantified for attaining sustainability in use and management.

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.

The agricultural sector faces daunting challenges because of climate change, particularly amidst increasing global water scarcity, which threatens irrigated lowland rice production. By 2025, 15-20 million ha of irrigated rice is estimated to suffer from some degree of scarcity. Rice systems provide a major source of calories for more than half of the world‟s population; however, they also use more water than other major crops. Irrigated lowland rice not only consumes more water but also causes wastage of water resulting in degradation of land.
