in order to study the effects of nitrogen and complementary irrigation on yield and its components of rainfed barley sahand cultivar, an experiment was conducted on split plot based on randomized completely block design with four replication in baft area at 2009-2010. factors were: four levels of nitrogen (0, 20, 40 and 60 kg/ha as pure nitrogen) from urea source as factor b and four levels of ...

In order to study the effect of irrigation interval, N fertilization and plant density on yield and yield components of fenugreek, a split-split-plot experiment was conducted in Darmian, Iran in spring 2010. The experiment was conducted in randomized complete block design with three replications. The main plots were subjected to different irrigation intervals of 5 and 10 days. The sub-plots wer...

water deficit is an important factor limiting crop growth all over the world. in order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. the experiments were carried out at the agricu...

High latitude agriculture is rainfed. Climate change could, however, increase water deficiency and initiate a call for development of irrigation systems as a part of field water management systems. This study aimed to develop a basic understanding about the current state of irrigation potential according to region by monitoring proximity of fields to waterways and characterizing their general c...

As planetary boundaries are rapidly being approached, humanity has little room for additional expansion and conventional intensification of agriculture, while a growingworld population further spreads the food gap. Ample evidence exists that improved on-farmwatermanagement can close water-related yield gaps to a considerable degree, but its global significance remains unclear. In this modeling ...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria(pgpr) on yield and yield components of chickpea (cicer arientinum l.) arman cultivar. this research was conducted as split plot based on randomized complete block design at zanjan university researchal farm. irrigation levels(optimum irrigation during season growth and no irrigat...

In the Mediterranean region, careful management of water and nitrogen utilization is required to achieve high crop yields in a sustainable and economic way. Prediction models are useful tools for deriving site/region–specific optimum management strategies for irrigation and nitrogen use. Yield-SAFE, a simple and robust model for growth and resource use in agroforestry systems, simulates crop yi...

soil salinity is one of the problems threatening agricultural lands. parts of this phenomenon are related to geologic formations and saltpans, while some major factors are resulted from irrelevant agricultural activities, issue of irrigation, and improper cultivation systems which lead to increase in soil salinity. to avoid such consequences that would end up with ecosystem degradation, suitabl...
