The aim of this study was to evaluate the efficiency of yield stability analysis models and to assess genotype × environment interaction effect on grain yield of 20 durum wheat genotypes for identifying high yielding and adapted genotypes by BLU and AMMI models using experimental data of four cropping cycles (2009-2013) in five filed stations in warm rainfed regions of Iran. The results of Like...
In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...
in order to study the effect of n fertilizer rates on morphological traits, yield and yield components of rice cultivars, a study was carried out in rice research institute of rasht, iran during 2009. it was a two-variable factorial experiment based on a randomized complete block design with three replications. the first factor was nitrogen fertilization at four rates of 0, 30, 60 and 90 kg n h...
Zinc (Zn) deficiency caused by inadequate dietary intake is a global nutritional problem, particularly in developing countries. Therefore, zinc biofortification of wheat and other cereal crops is being urgently addressed and highly prioritized as a research topic. A field study was planned to evaluate the influence of zinc application on grain yield, grain zinc content, and grain phytic acid co...
The research on reducing the water consumption in conventional cropping system is one of the important strategies to improve the water use efficiency in agriculture. In order to investigate the effect of time of potassium application under different irrigation regimes on millet grain yield and protein percent, a field experiment was carried out in Agricultural Research Center of Yasuj, Iran, in...
in order to study the responses of grain yield of chickpea to drought stress and application methods of nitrogen fertilizer, an experiment carried out as split-plot at campus of agriculture and natural resources, razi university, kermanshah, iran, during 2009-10 and 2010-11. the supplementary irrigation at three levels (1. without irrigation, 2. one irrigation at flowering, 3. two irrigations a...
To study the response of Hashemi (local) and Gilaneh (improved) rice cultivars to the application of different sources and levels of organic fertilizers, a field experiment was conducted using a randomized complete block design with three replications in 2018-2019 and 2019-2020 cropping seasons in research field of Rice Research Institute of Iran (Rasht), Iran. Experimental treatments include p...
to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...
Agroindustrial wastes such as spent grain, cocoa husk, rice bran and sawdust, unamended and amended with cattle, poultry and goat droppings were studied as to their effect on growth, fruit yield and nutrient composition of tomato (Lycopersicum escutentum Mill) in two experiments. Analysis of the wastes showed varying nutrient composition with C:N values of 11.1, 12.5, 23.3 and 18.2 respectively...
Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...
