Various strategies have been developed to reduce water consumption in rice cultivation, including rice cultivation in water-saturated soil, drying and wetting of the soil (periodic irrigation), and aerobic rice cultivation. In this study, in order to identify and grouping rice cultivars suitable for aerobic cultivation, 34 cultivars of native and improved rice cultivars were selected and eval...
To evaluate genetic diversity and to determine the relationships between yield and other importante traits among bean genotypes, an experiment was conducted in Random Completely Block Design (RCBD) with three repetitions under both normal and drought stress conditions in 2015-2016 crop season on 30 bean genotypes at Tehran University research farm. The results of variance analysis indicated hi...
In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur on some growth and yield components of Camelina sativa L., a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...
The pod drop and seed losses in rapeseed is one of the most important problems in the cultivation of this plant and determining the most appropriate harvesting time can greatly prevent this problem and subsequently reduce the grain yield reduction. Thus, the present research was conducted as a split-plot in time in the form of a randomized complete block design with three replications during th...
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
background and objectives:due to increase in the world population and increasing concerns about the future food security, shrinking the yield gap has became a hot area of research in field crops. estimation the amount of yield gap and determination of it’s causes requires using proper methods. boundary line analysis is a statistical method that can quantify the response of yield to an environme...
an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...
this research was designed to identify garlic (allium sativum l.) bolting clones and determining the relationship between their morphological traits and bolting capacity by using statistical methods of analysis of variance, comparison of means, correlation coefficients, factor analysis, stepwise regression, path analysis and cluster analysis. traits including flowering ability, number, length a...
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 order to investigate the effect of consumption of nitrogen and phosphorus fertilizers on harvest indices and some important agronomic traits of triticale (triticosecale wittmack var. javaniloo), a factorial experiment based on the randomized complete block design with three replications was conducted in paddy field of rice research institute of iran (rasht) during 2010-2012 for two years. th...
