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...

The study was aimed to determine the effect of soil ameliorant and inorganic fertilizers on nodulation and yield of some soybean varieties. Study was conducted under greenhouse condition in acid soils. Results revealed that all the tested varieties were compatible with native rhizobium at both study areas and showing the formation of nodules. A positive correlation was reported between the numb...

introduction integrated nutrient management involving crop residue/green manures and chemical fertilizer is potential alternative to provide a balanced supply of nutrients, enhance soil quality and thereby sustain higher productivity. the present experiment was undertaken to evaluate the effect of different crop residue management practices and npk levels on yield components and yield of wheat....

indian mustard is one of the most drought tolerant crops within brassica genus which could be used in semi dry areas of iran. 20 cultivars and lines of indian mustard were studied as complete blocks design with three replications in two different humidity regimes in oroumieh research station during 2013-2014 growing season. analysis of variance showed that the most studied agronomic characteris...

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...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
