A split plot factorial experiment in RCBD with 3 replications was performed in 2012-2013. Three sesame cultivars namely Biarjomand native, Dashtestan 2, and Darab 1 in the main plot were subjected to drought stress at different growth stages, i.e., control (full irrigation), withdrawing irrigation at 69 BBCH (end of flowering stage) and withdrawing irrigation at 79 BBCH (fully grown fruits). Tw...

Plastic mulched ridge-furrow irrigation is a useful method to improve crop productivity and decrease salt accumulation in arid saline areas. However, inappropriate fertilizer practices may result ecological environmental problems. In order the resource use efficiency these areas, we investigated effects of different amounts (400 (I1), 300 (I2) 200 (I3) mm) nitrogen application rates (300 (F1) 1...

this study was carried out to determine the optimal irrigation intervals in sugar beet seed production fields and to evaluate the effects of irrigation at different growth stages of sugar beet seed bearing plants (cv. shirin) on seed qualitative and quantitative characteristics. the treatments were four irrigation intervals including a control (i1) (irrigation at three stages; planting, bolting...

in order to study the effect of supplementary irrigation and different plant densities on grain yield and yield components of chickpea cv hashem, an experiment was conducted as split plot arrangement in a randomized complete block design with three replications in sirvan, ilam during 2008-2009 cropping season. main plot included supplementary irrigation (check as non-irrigation, supplementary i...

proper use of water resources in arid and semi-arid regions is important and vital. this study was conducted to evaluate the effect of irrigation scheduling by various methods on crop yield and water use efficiency (wue) by wheat, and determining suitable irrigation-scheduling method for irrigation of wheat in saeedabad, tabriz. a field experiment was conducted with 10 irrigation treatments (i1...

in order to study the responses of grain yield of chickpea to drought stress and application methods of nitrogen fertilizer, an experiment carried out as split-plot at campus of agriculture and natural resources, razi university, kermanshah, iran, during 2009-10 and 2010-11. the supplementary irrigation at three levels (1. without irrigation, 2. one irrigation at flowering, 3. two irrigations a...

The vegetative performance of chrysanthemum var. Marigold with respect to phenophase based irrigation and fertigation schedule was evaluated. In the phase, maximum plant height (62.44 cm), number secondary branches per (42.65), primary (10.85), leaf area (3793.81 cm2) recorded in treatment combination. Whereas, average spread (47.98 cm) I1F4, leaves (217.76) I3F1. Scheduling regime I3-(0.8 ER e...
