determination of the response of differentcrop varieties to environmental variables from planting to harvest is one of the fundamental pillars of agriculture planning to achieve maximum yield and desirable quality. changing planting date by effect on vegetative and reproductive growth period and balance between them, will affect yield and product quality. in order to study the responses of four...

The present study was conducted to find out correlation and path analysis for 10 yield attributing traits using 159 diverse pea genotypes. Correlation studies revealed that the days 50% flowering, node at which 1st pod appears, number of pods/plant, seeds/pod, length, weight picking had significant positive with total yield/plant while, plant height shelling percentage were negatively correlate...

introduction and aim: sennai (cassia angustifolia vahl) is one of the valuable plants which used to constipation treatment. production of organic plants is one of the goals of medicinal plant production, this is possible with the application of bio-fertilizers. in the past decades due to the use of chemical fertilizers numerous environmental impacts, including soil and water pollution problems ...

the effect of water stress were studied on the agronomic traits related to yield of common bean by planting 32 genotypes in normal and water deficit conditions. these genotypes were evaluated in randomized complete block design with three replications in experimental field of faculty of agriculture, university of tehran, karaj campus in 2007. analysis of variance showed that there were signific...

introduction water availability is an important factor affecting plant growth and yield, mainly in arid and semi-arid regions, where plants are often subjected to periods of drought. the occurrence of morphological and physiological responses, which can lead to some adaptation to drought stress, may vary considerably among species. in arid and semi-arid areas that are subjected to more irregula...

in order to evaluate the effects of drought stress and planting method on yield and yield components of two chickpea cultivars (cicer arietinum l.), an experiment was carried out at the research field of faculty of agriculture; shiraz university, using a split factorial randomized complete block design with four replications. the main factor was irrigation stop at different growth stages of chi...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

to evaluate canola cultivars response to physiological characteristics and grain yield end seasonal drought stress in weather condition of ahvaz, farm experiments were done at research farm of khuzestan agriculture and natural resources center. during 2007-2008 and 2008-2009 crop years. farm test comprised drought stress was done as split plot form with randomize complete block design with four...
