A field experiment was conducted to study the effect of different weed control practices on weed dyanamics, nutrient uptake and yield of wheat (Triticum aestivum L.) in rabi seasons of 2010-11 and 2011-12 at Crop Research Centre of SVPUAandT, Meerut. The treatments comprising pre-emergence application of pendimethalin @ 1000 g/ha, post emergence application of isoproturon @1200 g/ha, isoproturon+2,4-D @ 1200+600 g/ha, isoproturon+metsulfuron methyl @ 1200+4 g/ha, fenoxaprop -p-ethyl @ 80 g/ha, fenoxa prop -p-ethyl +2,4-D @ 80+600 g/ha, fenoxa prop -p-ethyl +metsulfuron methyl @ 80+4 g/ha, clodinafop propargyl @ 60 g/ha, clodinafop propargyl+2,4-D @ 60+600 g/ha and clodinafop propargyl+metsulfuron methyl @ 60+4 g/ha were tested with weed free and weedy check. Among the herbicides, application of clodinafop propargyl+ metsulfuron (60+4 g/ha) though statistically on par with clodinafop propargyl+ 2,4-D (60+600 g/ha) reduced the weed population significantly than weedy check (97.2%), clodinafop propargyl alone (88.0%), fenoxaprop -p-ethyl alone (83.0%), isoproturon alone (80.0%), isoproturon+metsulfuron (72.2%), pendimethalin (71.4%), isoproturon+2,4-D (53.8%), fenoxa prop -p-ethyl +2,4-D (53.8%) and fenoxa prop -p-ethyl + metsulfuron (40.0%) at 60 days after sowing stage. Among the herbicides, application of Clodinafop propargyl+ metsulfuron methyl (60+4 g/ha) as post emergence resulted into highest grain yield of wheat (49.28q/ha) which was on par with weed free and clodinafop propargyl+2,4-D @ 60+600 g/ha but statistically significant than rest of the treatments. Highest NPK uptake by grain and straw of wheat was recorded in weed free conditions compared to the herbicidal treatments, except lodinafop propargyl+metsulfuron methyl and clodinafop propargyl+ 2, 4-D. Highest removal of NPK (63.6 kg/ha) by weeds was recorded in weedy check whereas, the minimum NPK uptake (28.4 kg/ha) was noticed with the application of clodinafop propargyl+metsulfuron methyl due to efficient control of weeds (weed control efficiency 84.7%), which resulted in lowest weed dry matter in this treatments.

Dry Matter Accumulation

A 3-yr study was conducted on three Orthic Black Chernozemic soils to determine the effects of incremental N fertilization on grain yield and dry matter accumulation and distribution of six spring wheat (Triticum aestivum L.) cultivars. Urea (46–0–0) was sidebanded at seeding in 40 kg N ha−1 increments from 0 to 240 kg ha−1 in the first year and from 0 to 200 kg ha−1 in the 2 subsequent years. Nitrogen fertilization increased the grain and straw yields of all cultivars in each experiment. The predominant factor affecting the N response and harvest index of each cultivar was available moisture. At two of the three sites, 91% of the interexperiment variability in mean maximum grain yield was explained by variation in root zone moisture at seeding. Mean maximum total dry matter varied by less than 12% among cultivars, but mean maximum grain yield varied by more than 30%. Three semidwarf cultivars, HY 320, Marshall and Solar, had consistently higher grain yield and grain yield response to N than Glenlea and Katepwa, two standard height cultivars, and Len, a semidwarf. The mean maximum grain yield of HY 320 was the highest of the cultivars on test and those of Katepwa and Len the lowest. Len produced the least straw and total dry matter. The level of N fertilization at maximum grain yield varied among cultivars, sites and years. Marshall and Solar required the highest and Len the lowest N rates to achieve maximum grain yield. The year-to-year variation in rates of N fertilization needed to produce maximum grain yield on a specific soil type revealed the limitations of N fertility recommendations based on "average" amounts and temporal distribution of available moisture.Key words: Wheat (spring), N response, standard height, semidwarf, grain yield

End Use

Sadash is a soft white spring wheat (Triticum aestivum L.) that meets the end-use quality specifications of the Canada Western Soft White Spring class. Sadash is well-adapted to the wheat-growing regions of southern Alberta and southern Saskatchewan. Based on data from the Western Soft White Spring Wheat Cooperative Registration Test from 2003 to 2005, Sadash exhibited high grain yield, mid-season maturity, semi-dwarf stature with very strong straw, and good resistance to shattering. Sadash expressed resistance to the prevalent races of stem rust and powdery mildew, intermediate resistance to loose smut, moderate susceptibility to leaf rust and common bunt, and susceptibility to Fusarium head blight. Based on end-use quality analysis performed at the Grain Research Laboratory of the Canadian Grain Commission, Sadash had improved test weight over the check cultivars AC Reed and AC Phil and similar milling and baking performance.Key words: Triticum aestivum L., cultivar description, wheat (soft white spring), grain yield, quality, disease resistance
