introduction grain legumes are considered as the second source of human nutrition after cereals and play an important role in community food supply, sustainable agriculture and economic profitability. among grain legumes, common bean has the most consumption in the world compared with others. however there are always some constraints in common bean production and drought is most important facto...
A diallel analysis of eight bread wheat (Ttriticum aestivum L.) cultivars was conducted to determine genetic parameters and the type of genetic control for yield and yield components. The parents and their F1 hybrids were evaluated in a randomized complete block design with 3 replications. General and specific combining ability effects were estimated by the method 2 of the Griffings model I, an...
long season and high temperature during spring in hot and dry areas has led to tendency for autumn planting. in order to evaluation of chickpea (cicer arietinum l.) autumn planting possibility, a field experiment was done at the agricultural faculty and natural resources of saravan research field in 2010. experimental design was done as split plots based on randomized complete block design with...

introduction: more plains of iran are located in arid and semi-arid regions and so agricultural production systems depend heavily on water. recently, the reduction of water resources has become a serious threat for crop production such as cotton planting. therefore, application of low irrigation methods can be an appropriate method to cope with mentioned condition. in addition, it is vital to i...
In order to study the effects of rate and time of nitrogen application on vegetative characters, i.e., yield and yield components of rice (Zayandeh-rood variety), an experiment was conducted at Isfahan University of Technology research farm during summer 1996. Four N rates including (60, 90, 120 and 150 KgN/ha) and four splitting form (1- all N applied before transplanting 2- 1/3 N applied befo...
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...
in order to investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...
Scarcity of water for irrigation is an alarming issue of Pakistan and the problem is being magnified rapidly with the passage of time. Shortage of water is thus, a limiting factor in increasing per unit area wheat (Triticum aestivum L.) yield that is staple food of most of the people. Eventually, the gap between production and consumption is widening day by day and Pakistan is now suffering fro...
An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...
