Supplementary irrigation moderates the damage caused by drought stress in rainfed agriculture. Meanwhile, the application of nano fertilizers and methanol as the foliar application can be considered as effective management strategies to improve production under dryland conditions. For this purpose, the effect of supplementary irrigation, nano fertilizer spraying, and methanol foliar spraying wa...
effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...
In order to investigate the effects of deficit nitrogen application on growth and yield in sole cropping and intercropping of canola and pea, a factorial experiment was conducted as randomized complete block design with three replications at Shahrekord University Research Farm, Sharekord, Iran during 2011- 2012 growing season. Five planting ratios (100% canola 66% canola + 33% pea, 50% canola +...
abstract field experiment was conducted to evaluate the effects of sowing date, crop density, and weed interference on yield and yield components of chickpea in lorestan province during 2005-06. the experimental was a randomized complete block design by factorial arrangement with 4 replications. the experiment had 3 factors: sowing date at 2 levels (autumn, and winter), crop density at 3 levels...
The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
The present study was undertaken to evaluate direct and indirect selection criteria for the improvement of grain yield and quality components in Chenopodium quinoa Willd. Correlated response (CR) and relative selection efficiency (RSE) were estimated for grain yield and three quality components, grain protein, grain carotenoid and leaf carotenoid based on different contributing ...
abstractbackground and objectives the oilseeds after cereal, the world's second largest food supply make up. environmental stress has always been one of the most important factors reducing crop yield and production are gone and counter or reduce the effects of stress as a useful strategy to increase the quality and quantity of the products has been considered. flooding conditions are said ...
in this study, microwave-assisted solvent extraction (mase) was used to recover oil residues from pomace olive using acidic hexane. results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. for both radiation powers used (170 and 510w), the optimal extraction time and most interesting content of acetic acid in hexane ar...
The sensor nodes in a Wireless Sensor Network are generally constrained with limited power supply. Efficient power management is a must for any sensor network to keep the sensor nodes in the network to be operational for a longer period of time this increasing the lifetime of the sensor network. Hierarchy based routing enables the sensor networks to be deployed in larger areas. In this paper we...
