Optimum planting geometries have been shown to increase crop yields in maize-soybean intercrop systems. However, little is known about whether changes in planting geometry improve the seasonal water use of maize and soybean intercrops. We conducted two different field experiments in 2013 and 2014 to investigate the effects of changes in planting geometry on water use efficiency (WUE) and evapot...
Agricultural investigations use computer models for simulation of crop growth and field water management. By using these models, the effects of plant growth parameters on crop yields are simulated, hence, the experimental costs are reduced. In this paper, the model of MSM (Maize Simulation Model) was calibrated and validated for the prediction of maize forage production at Agricultural College,...
determination of the response of differentcrop varieties to environmental variables from planting to harvest is one of the fundamental pillars of agriculture planning to achieve maximum yield and desirable quality. changing planting date by effect on vegetative and reproductive growth period and balance between them, will affect yield and product quality. in order to study the responses of four...
In order to evaluate the effect of autumn and winter planting on yield and phenology of potato cultivars using thermal indices an experiment was coducted in split plot in time based on a radomized compelet block design with three replications at Behbahan Agriculture Research Station in Khuzestan province, south of Iran in 2014 and 2015. Cultivar (Sante, Savalan and Javid) was considered as main...
Seizures is a major toxicity of theophylline. The mechanism of theophylline-induced seizures is not known, but antagonism at adenosine receptors may be a possibility. The effect of pretreatment with different doses of adenosine (100, 500 and 1000 mg/kg, i.p.), and the adenosine A1 receptor agonist N6-cyclopentyladenosine (CPA), 1, 5 and 10 mg/kg, i.p., was studied against seizures induced by th...
This experiment was conducted to determine the effects of time and rate of nitrogen fertilizer (urea) application on yield and yield components and quality of sunflower (Helianthus annuus L. )cv.Euroflor. A field experiment was carried out at College of Agriculture, Shiraz University during Summer 2009. The experimental design was a factorial based on a randomized complete block design with 3 ...
Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...
Thermobaric charge PBXIH-135 is an explosive with desirable mechanical and safety characteristics. In present research, this PBX charge is provided on scale of 2 kg and its physical, mechanical, sensitivity and performance parameters were investigated. Prepared sample has density of 1.64 g/cm3, hardness of 53 Shore A, tensional strength of 1.68 MPa and strain of 44%. Impact and friction sensiti...
in arid, semiarid, and mediterranean climates, particularly in west asia and north africa, farmers face limited water resources and must develop irrigation management methods to increase crop production while reducing water use. this study examined methods to reduce irrigation water loss and increase maize water productivity at safiabad agricultural research center in dezful, iran in 2007 and 2...
