The experiment included two factors: first, biological phosphate fertilizer (fertile 2) at three levels of 0, 100, 200 g/ha; second, triple super phosphate chemical fertilizer at three levels of 0, 60, 90 kg/ha of pure phosphorus (P2O5). The obtained results indicated that fertilizer treatments had a significant effect on some morphological traits at 1% probability level. In this regard, P2B2 treatment (100 g/ha biological phosphate fertilizer (fertile 2) and 60 kg/ha triple super phosphate fertilizer) had the greatest plant height, stem diameter, number of leaves and ear length.

The treatments studied in this experiment consisted of the main factor including three levels of nitrogen fertilizer (50, 125, 200 kg/ha) and the sub factor including three levels of cycocel concentration (0, 1500, 3000 mg/l). The results showed that the use of cycocel increased the number of spikes/m2, number of grains per spike, grain yield, biological yield, and harvest index compare to the control treatment. The highest grain yield belonged to the treatments with 124 and 200 kg/ha nitrogen. In general, the results of the research showed that the best level of nitrogen was 125 kg/ha and the best concentration of cycocel was 1500 mg/l.

Due to its adaptation to arid condition and high-water use efficiency, it may produce satisfactory seed yields in arid conditions. The present study was conducted in Khorramabad province during two crop years of 2016 - 2017. The experiment was conducted in a randomized complete block design with split-factorial arrangement with four replications. The stress factor was assigned to main plots through three levels of irrigation, normal irrigation, and irrigation at vegetative and reproductive stages, and sub-factor to subplots, consisted of three levels of biofertilizer, soil NPK application, soil vermicompost application, and vermicompost and chemical fertilizer combining with Sepideh and Kimia cultivars. Initially, combined analysis of variance was performed. Due to the lack of significant year effect and its interaction effects by different factors, analysis of variances was performed on two years data. The effects of stress and the interaction effects of cultivar by stress and fertilizer on some traits were measured. It was found that the quantitative, qualitative and phonological indices of sorghum were directly negatively affected by stress at the reproductive stage. On the other hand, the effect of vermicompost fertilizer on the studied traits was significant and positive. Sepideh possessed the highest vahues for those traits except for protein percent, in comparison to Kimia. Grain yield was about 8 ton at irrigation-interrupt during vegetative stage for Sepideh and 4.36 t.ha<sup>-1</sup> for Kimia, but grain yield at irrigation-interrupt during reproductive stage was 7.67 and 4.45 t.ha<sup>-1</sup> for Sepideh and Kimia, respectively.

In this regard, in order to examine the rate and the way of distribution of nitrogen fertilizer and its effect on the yield and yield components of grain sorghum (Sorghum bicolor L. Moench) a split plot experiment as randomized complete block design with three replications was carried out in Shahid Salemi research field located in Ahvaz in [2011][2012].

The results showed that the effect of different levels of intercropping ratio on dry weight of the plant organs and total dry matter was not significant, but the intercropping ratio of 25% maize and 75% soybean was determined as the superior intercropping ratio. In this ratio, the maize allocated the highest total dry weight (14.37 t/ha) and the highest l...

In order to investigate the effect of sowing date and plant density on growth physiological parameters, yield and yield components, a split plot experiment on cowpea (local cultivar) was carried out as randomized complete block design with four replications in Dehloran area in Ilam in 2010-2011. Experimental treatments included three sowing dates (July 6, July 23, and August 6) as main plots and four plant densities (17, 24, 31, and 38 plants per square meter) as sub plots. The results showed that there was a significant difference between different sowing dates and plant density in terms of their effects on traits such as number of pods per plant, number of grains per plant, number of lateral branches, ...
