Experiments were carried out at Lumle Centre (1675m) and its Off Station Research Sites Keware Bhanjyang (1250m), Yampaphant (450m) and Rishing Patan (420m) and Singana (1250m) during the winter seasons of 1991192, 1992193 and 1993194 in order to assess the most important yield limiting constraints of wheat cultivation under rainfed and irrigated conditions. A minus one technique was used to test the importance of management factors by omitting them from a full package of practices comprising the recommended practices for those factors (nutrition, weed control, pest and disease control etc)………………………..
