A field experiment was conducted to estimate potassium (K) and yield losses by Chenopodium album in wheat under different competition periods. The study consisted of zero competition, competition for 3,4,5,6,7,8 weeks after emergence (WAE), and for full season. Potassium concentration in C. album was maximum (4.91 %) w …

Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under varying degrees of water stress. Field Studies were conducted in 1992 and 1993 to assess methods for evaluating genotypes with combined high yield potential and stability, in both years, 1 …

Yield and developmental characteristics of crop genotypes grown at different levels of water availability are often used to select genotypes that are adapted to variable moisture environments. Field studies were conducted at Aberdeen. Idaho, USA in 1992 and 1993 to evaluate the effects of varying moisture supply on gra …

Two field experiments were conducted to determine the economic threshold level of C. album and P. minor in wheat. Different densities viz., check (weed free). 50. 100. 150. 200. 250. 300. 350. 400. 450 and 500 m-2 of each weed species were maintained separately. Grain yield obtained from plots having C, album densities …

A field experiment was conducted to estimate nutrient losses by Phalaris minor Retz, in wheat under different fertilizer application methods and competition periods. The study consisted of a Side-placement and a broadcast incorporate method of fertilizer application, and competition periods of O, 3, 4, 5, 6, 7 and 8 wk …
