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...
this experiment was carried out in factorial arrangement based on randomized complete block design with three replications in agricultural and natural resources research center of markazi province, arak (iran) during 2008-2009 growing season. three application rates of sulphur (s1=0, s2= 40 and s3=80 kg/ha) and three rapeseed varieties (okapi, modena and licord) comprised the experimental facto...
this research was conducted on determination of better planting distance and better amount of nitrogen and phosphorus for hybrid rice (bahar 1). planting distance were used in this experiment, include 30×15, 30×20 and 30×25 cm as main factor. and also nitrogen fertilizer was used, include four levels, 65, 95, 125 and 155 k/ha and phosphorus fertilizer used include tow levels, 50 and 100 k/ha as...
With the increase of population, the optimal use of water resources is necessary. This study was carried out to evaluate the impact of different levels of irrigation on the yield, yield components and water productivity of corn using single and double row drip irrigation systems (Tubes type). . The experiment was conducted in a split plot design based on the randomized complete block design (RC...
Abstract: The cultivars IAC 201CS and 201CO have a mean cycle of 100 110 days, 1000 seed weight 18 6 grams, total fresh matter 26,287.81 36,174.12 kg ha-1, 812.57 1,017.09 respectively.
It is believed that various types of field bean, including pinto, white and red, differ in adaptability to high temperatures and may, thus, differ in response to delay in planting. In order to evaluate this response, an experiment was conducted during 1996 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with split-plot layout. M...
nitrogen is one of the most limiting nutrients for cereal production in many parts of iran. the effects of crop residue incorporation [0 (control), 25 and 50% of wheat (triticum aestivum l.)] and nitrogen (n) levels (0, 150, and 300 kg ha-1) on corn (zea mays l.) grain yield and nitrogen use efficiency were investigated at agricultural research station, shiraz university, shiraz, iran for two y...
in order to study the effects of irrigation regimes, planting season and seed priming on grain yield and components of hashem genotype of chickpea in nurabad, northern lorestan, two 3-replicate split-plot field experiments, one autumn- and the other spring-sown, were conducted. the primed and non-primed seeds (subplots) of this chickpea genotype were sown in autumn and spring and subjected to f...
The goal of this study was to observe the impact of agro-management practices like, irrigation and nutrition on two pea (Pisum sativum) cultivars named Climax and Meteor at Horticultural Research Area, U.A.F. Growth parameters like Main stem Length (cm), number of leaves per plant, leaf Area (cm), number of pods per plant, length of pod (cm) number of seeds per pod and reproductive attributes l...
The use of efficient and effective nodulating Bradyrhizobia strains considered as anecologically and environmentally sound management strategy for soybean production. A 2-yr(2009 and 2010) field experiment was conducted to evaluate the effects of seven indigenousBradyrhizobium strains, one exotic TAL-102 and three N fertilizer rates, i.e., 25, 50 and 100kg N ha-1 on the productivity and N2 fixa...
