To investigate the effect of depth of planting holes on yield and yield components of three cultivars of watermelon in dry land conditions, a two-year study (2006-2007) was carried out in Varamin Agricultural Research Center, using a split plot randomized complete blocks design in three replications. Three cultivars of watermelon (Mahbube, Charleston Gray and Sugar Baby) were assigned to main p...
In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...
Rapeseed needs a sufficient amount of nitrogen for optimal seed yield, but the efficiency of this plant in using nitrogenous (N) fertilizers is low, which causes an increase in N consumption in the cultivation of this plant. The need to maintain a high grain yield necessitates the use of a suitable timely program and manage the consumption of N fertilizers. Thus, a field experiment was conducte...
the performance of new forage brassica plants were studied in ilam, iran, during 2012-2014 in a field experiment using a randomized complete block design with four replications. the treatments included, different forage crops perko, buko, oilseed radish, berseem clover, and the combination of three plants ramtil, phaselia, and clover. the studied traits consisted of plant height, forage yield, ...
this fertility experiment was carried out using split plots based on a randomized complete block design of three replications in 2006 at sari agricultural sciences and natural resources university. the aim of the experiment was to investigate some macronutrient and micronutrient accumulation in leaves of different soybean cultivars as influenced by some organic fertilizer types and levels. main...
ABSTRACT- In order to study the effects of different irrigation regimes and plant density on yield and yield components of bean, a split plot arrangement was conducted in complete randomized block design during two years. The foremost variable was four levels of irrigation: 60, 80, 100, and 120% of the potential evapotranspiration. The second variable was within the row spacing of 5 cm (D1), 10...
The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...
In order to investigate the effects of moisture stress, nitrogen fertilizer, manure and integrated nitrogen and manure fertilizer on yield, yield components and water use efficiency of SC 704 corn (late maturing, non-prolific and dent). In 2005, a field study was conducted in agricultural experiment station of the college of agriculture, Tarbiat Modares University. The type of design was random...
