Performance of Zero-till Wheat (Triticum aestivum L.) and Weed Species as Influenced by Residue and Weed Management Techniques in Rice based Cropping System

Rice (Oryza sativa L.) Wheat (Triticum aestivum L. emend Fiori & Poal) cropping sequence is the most predominant production system occupying about 18 Mha in Asia, of which 13.5 Mha area in Indo-Gangetic Plains (IGP) of India (10 Mha), Pakistan (2.2 Mha), Bangladesh (0.8 Mha) and Nepal (0.5 Mha) and feeds about 1.3 billion people (20% of the world population) (Farooq et al., 2007, Saharawat et al., 2010). This grin scenario is stemmed from the exhaustive nature of both the crops because belonging to the same family and their extreme tillage requirement. The new Resource Conservation Technologies (RCTs) develop over the past ten years provide an opportunity to reduce the cost of production. Among these, new RCTs, the zero tillage technologies of wheat cultivation have been adopted over large areas. This technology save more than 90% energy, time, labour and helps to produce wheat at a much lower cost.
