In most fruit tree orchards under localised irrigation, only a fraction of the rhizosphere is wetted by irrigation. As this may reduce growth and production, such that there demand for information on optimum number location emitters. mature ‘Arbequina’ olive orchard with 1667 trees ha-1, we analysed impact applying same amount water one vs. two drip irrigation pipes (laterals) per row. We had f...

ABSTRACT- Maize production, which is ranked after wheat and barely in Fars province, Iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. Therefore, proper planting method can improve irrigation water management. The objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...

in order to study of deficit irrigation levels on wheat grain yield cultivars based on water productivity indices, an experiment was conducted in a split plot arrangement in randomized complete block design at the field of agricultural and natural resources center of isfahan (kabutarabad research station). three levels of irrigations: 60% of full irrigation (f1) and 80% full irrigation (f2) and...

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

deficit- irrigation is one of the measures for water saving and optimum application of water in surface irrigation. however, lack of enough evidences, doubts on the proper application of deficit- irrigation, dissemination of research results and its application by the farmers are of practical challenging issues. this paper summarizes and analyzes some research results on deficit- irrigation in ...

Shortage and salinity of irrigation water are two major constraints that influence rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effects of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) as strategies for coping with water and salinity stresses on yield and yield quality of rapeseed were invest...
