Grain Filling Rate and Duration in Bread Wheat Under Irrigated and Drought Stressed Conditions
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
متن کاملNon-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
متن کاملSaline/Sodic sub-soil on triticale, durum wheat and bread wheat yield under irrigated conditions
Sub-soil (> 30 cm) salinity and sodicity is a growing problem particularly in irrigated agricultural areas with rising water tables, poor water quality and/or deficient soil drainage. There were two objectives in this study; (1) to quantify the effect of sub-soil salinity and sodicity in grain yield of triticale, bread wheat and durum wheat and, (2) to determine if genotypes within and between ...
متن کاملPhosphorus use efficiency, grain yield, and quality of triticale and durum wheat under irrigated conditions
After nitrogen stress, phosphorus is the second most widely occurring nutrient deficiency in cereal systems around the world. The objectives of this study were: (1) to look at the effect of changes in phosphorus use efficiency and responsiveness on grain yield and quality of triticale and durum wheat with respect to an old tall durum wheat of the early 1940s, Barrigon Yaqui. A two-year field ex...
متن کاملSimulation of Nitrogen Balance in Rice–Wheat Systems of the Indo-Gangetic Plains
Crop growth simulation models provide a means to quantify the effects of climate, soil, and management on crop growth and biogeochemical processes in soil. The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate N dynamics and balance in the rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping systems in the Indo-Gangetic Plains with various N and wa...
