The field experiments were conducted on sandy loam soil at New Delhi, during 2007 and 2008 to investigate the effect of conservation tillage, irrigation regimes (sub-optimal, optimal and supra-optimal water regimes), and integrated nutrient management (INM) practices on soil biological parameters in wheat cultivation. The conservation tillage soils has shown significant (p<0.05) increase in soi...

such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

to identify important attributes/factors that contribute to grain and biological yields of wheat, 9912 sets of diverse data from field studies were extracted, and supervised attribute-weighting models were employed. results showed that when biological yield was the output, grain yield, nitrogen applied, rainfall, irrigation regime, and organic content were the most important factors/attributes,...

to investigate the effect of deficit irrigation and macro and micro fertilizers on morpho-physiological characteristics of satureja a field experiment was conducted in agricultural research station of haji-abad (hormozghan province-iran) a split plot randomized complete block design with three replications during the growing season of 2012-2014. irrigation treatments consisted of normal, modera...

BACKGROUND: Deficit irrigation strategies were effective in saving volume of water. Potassium is an essential nutrient that affects most of the biochemical and physiological processes are involved in plant resistance to biotic and a biotic stresses. OBJECTIVES: This study was conducted to assess effect of different pattern of irrigation and several source...

BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...

Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...

To ensure the optimal water-air balance of plant, agro-reclamation measures are required, including organization irrigation. The advantage drip irrigation is most rational consumption water. realize this advantage, it necessary to calculate rate taking into account dynamics moisture distribution in soil. During irrigation, humidification circuit takes on a semi-elliptical shape. determine geome...
