to evaluate the competition effect of velvetleaf on cotton, an experiment was conducted in a completelyrandomized block design with split plot arrangement of treatments with three replications at experimentalstation of gorgan university of agricultural sciences and natural resources during 2011 growingseason. the treatments were three row spacing (20, 40 and 80cm) of cotton (as main plot) and f...
in order to study the effects of supplemental irrigation and planting arrangement on yield, yield components and water use efficiency (wue) of kabbuli chickpea (cv. arman), an experiment was carried out at the agricultural research station of gonbad for two years, iran. the experiment was a split-plot factorial arranged in a randomized complete block design with three replications. the main plo...
background and objectives: potato (solanum tuberosum l.) plant is one of leading agricultural products in the world. it is the fourth most cultivated food crop after wheat, rice and maize. planting density and weight of minituber are the factors influencing on the yield and yield components on seed tuber production in potato. plant density strongly affected yield, both by number and by weight a...
Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
Optimum rice population densities and the response of rice yield and yield components to population densities and planting pattern are important factors helping rice producers and researchers to achieve maximum productivity. For this reason, a randomized complete block design experiment was conducted during the summer of 1995 at Isfahan University of Technology Research Farm located at Lavark, ...

in order to investigate the effects of row intercropping of bean (phaseolus vulgaris l.) with borage (borago officinalis l.) on its ecological characteristics such as weed and insect diversity, composition and density and their yield and evaluating of the best strip width, a field experiment was conducted based on randomized complete block design with three replications at the agricultural rese...
Due to yield increase, some farmers in Iran plant sugarbeet in 50-cm row spacing instead of conventional 60-cm row spacing. Low row spacings force farmers to harvest three consecutive rows instead of two alternate rows. This would increase the amount of draft requirement to pull the lifter through the soil. In order to use common medium tractors for pulling the three-unit sugarbeet lifter and p...
In order to investigate the effect of planting arrangement on growth indices and grain yield of a red bean cultivar (Sayyad cultivar), The experiment was conducted in a split-plot randomized complete block design with 4 replications in Jihad Agricultural Services Center of Al-Mahdi town, Azna. The main factor consisted three row spacings including 20, 30 and 45 cm and the sub-factor consisted t...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
