introduction safflower is native to iran, and is cultivated for high adaptability, low water requirement, resistance to drought and useful unsaturated fatty acid (ashri et al., 1977). identification of effective agronomic traits and relationship between them are important aims under water stress conditions. among these characters, grain yield is the most important trait that is genetically poly...
Estimating balanced nutrient requirements for soybean (Glycine max [L.] Merr) in China is essential for identifying optimal fertilizer application regimes to increase soybean yield and nutrient use efficiency. We collected datasets from field experiments in major soybean planting regions of China between 2001 and 2015 to assess the relationship between soybean seed yield and nutrient uptake, an...
In order to evaluate the effects of biofertilizers and nitrogen application on oil, yield and its components in spring rapeseed Var "Hayola 401", a field experiment was carried out by a split plot design based on a randomized complete block design with 4 replications, in Agricultural Research Station ( Dr. Nakhjavani) of Urumia during 2007- 2008. The main plot included of three levels of nitro...
Sowing date and genotype are factors affect different growth stages and yield of soybean. To evaluate the effect of sowing date and genotype on seed yield of soybean a field experiment was carried out as split plot arrangement in randomized complete block design with three replications at Safiabad Agricultural and Natural Resources Research and Education Center, Iran, in 2016 and 2018. The main...
To determine the effect of sowing dates (22 Oct., 5 Nov., 21 Nov. and 5 Dec.) on the green pod and dry seed yield of faba bean (Vicia faba), field experiments were conducted using RCB design with four replications for three cropping seasons (1995-1998) at Hashem Abad Research Station in Golestan Province. Result, of combined analysis of variance showed that 22 Oct. and 21 Nov. produced higher g...
The efficiency of a breeding program depends mainly on the direction of the correlation between yield and its components and the relative importance of each component involved in contributing to seed yield. The objective of this study was to detection of traits affecting canola yield by multivariate analysis, at Khozestan Province, Iran, in the agricultural year in 2015–2016. A randomized compl...
in this study, several artificial neural networks (anns) were developed to estimate seed and grain corn yields in parsabad moghan, iran. the data was collected by a face-to-face interview method from 144 corn farms during 2011. the energy ratios for seed and grain corns were calculated as 0.89 and 2.65, respectively. several multilayer perceptron anns with six neurons in the input layer and one...
to evaluate the effects of some phosphorus solubilizing bacteria strains on yield and agronomic traits in local bean (phaseolus vulgaris l.) of guilan, different phosphate fertilizer rates were tested during 2014 growing season. this research was carried out in experimental field of agricultural and natural resource research center of guilan province as split plot arrangement based on randomize...
Drought is considered as the most important constraint to world’s crop production. Furthermore arid and semiarid climate accounts for nearly most of terrestrial areas of Iran. Therefore in order to study the effect of irrigation regimes on growth, physiological attributes and grain yield as well as components of such a crop plant as safflower a 4-replicate split plot RCBD field study was perfor...
One of the most complicated issues in plant breeding programs is genotype by environment interaction. To evaluate seed yield stability of 18 chickpea promising lines, a field experiment was conducted using randomized complete block design with four replications in two cropping seasons (2018-19 and 2019-2020) in four research stations (Maragheh, Kurdistan West Azerbaijan and Hamedan), Iran. Comb...
