The existence of a shallow water table (surface to 0.54 m from June to October) is common phenomenon in Tarai (foothills of the Himalaya) of Uttar Pradesh, India. Puddled rice (Oryza sativa L.) crop followed by conventional land preparation for the succeeding wheat (Triticum aestivum L.) crop is normal cultivation practice in the region. This shallow water table can be effectively utilised to a...

terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...

Water stress is one of the major abiotic stresses in agriculture worldwide. In order to assess photosynthesis response and grain yield of 25 wheat genotypes under water deficit (post-anthesis stress) conditions, a 2-year study (2010-12) was carried out as a split-plot arrangement using randomized complete block design with three replications. The most sensitive gas exchange variable to water de...

Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves. On the other hand, sequential senescence involves leaf senescence that follows an age-related pattern, in which flag leaves are the latest to undergo senescence. The characteristics of sugar metabolism in two sequential senes...

The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi to study the yield and yield components of wheat as affected by phosphorus fertilization. The experiment consisted of two factors i.e. (i) three wheat varieties viz., Shatabdi, Bijoy and Prodip and (ii) five levels of phosphorus viz. 0, 30, 60, 90, 120 kg P2O5...

Wheat yield and grain nitrogen concentration (GNC; mg N/g grain) are frequently negatively correlated. In most growing conditions, this is mainly due to a feedback process between GNC and the number of grains/m2. In Mediterranean conditions, breeders may have produced cultivars with conservative grain set. The present study aimed at clarifying the main physiological determinants of grain nitrog...

physiological study of wheat varieties under abiotic stress conditions is a very important factor for improving their future productions. this research work was conducted in the research greenhouse of faculty of agriculture, tarbiat modarres university in 2006, to study leaf quantitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv ...
