ABSTRACT- The aim of this study is economic analysis of supplemental irrigation (SI) for rain-fed fig trees in the south of Iran, with and without micro-catchment water harvesting systems (MCWHS). Under no MCWHS, by decreasing about 55 % of applied water, the fig yield decreased about 28% and net income increased twice compared with the maximum yield condition. In general, the ...

The conservation of water is crucial to sustainable agricultural production in areas of low rainfall or uneven precipitation distribution. Under such circumstances, drip irrigation methods offer a useful option for economic production of vegetable crops. This preliminary study examined the efficacy and performance of two drip irrigation methods on cucumber and tomato crops grown out of season. ...

Drought stress is a major factor limiting wheat crop production worldwide. The application of humic acid (HA) and the selection appropriate genotype in suitable site one most important methods tolerance plants to drought-stress conditions. aim this study was achieved using three-way ANOVA, index (STI), Pearson correlation coefficient (rp), principal component analysis (PCA). Three field experim...

ABSTRACT: The objective was to evaluate the effects of water depths and irrigation frequencies on structural responses, forage yield chemical composition spineless cactus Orelha de Elefante Mexicana (OEM) (Opuntia stricta (Haw.) Haw), in adensed crop system. experimental design randomized blocks, subdivided plots (3x4) with 4 replicates. were (100%, 75%, 50%, 25% ETc - evapotranspiration) three...

Most short rotation coppice (SRC) plantations are grown in temperate, subtropical, and tropical areas where land availability is limited. Very little known about the potential biomass yield of Eucalyptus camaldulensis as SRC under semi-arid conditions with supplemental irrigation. Our objective was to maximize production E. a feedstock for biofuels by optimizing initial stem density (ISD) irrig...

Shortage of water resources is a major limiting factor for wheat (Triticum aestivum L.) production in the North China Plain. The objectives of this study were to evaluate the effects of supplemental irrigation (SI) on water use characteristics and grain yield of the wheat cultivars ‘Jimai 22’and ‘Zhouyuan 9369’. Two supplemental irrigation treatment regimens were designed based on target relati...
