To evaluate the effects of various levels of phosphorous and foliar application of iron and zinc on grain yield and yield components of chick pea (Ciceraireintinum L.), an experiment was conducted on split plot factorial based on randomized complete block design with three replications during 2010- 2011 growth season at the Agricultural College Research Farm, Lorestan University. Factors included phosphorous fertilizer at three levels (P1=0 kg/ha, P2=100 kg/ha, P3=200 kg/ha, soil application) in the main plots. Fe and Zn each at three levels (F1, Z1=0, F2, Z2 = 0.3 and F3, Z3 =0.6 percent, foliar application) were placed in the sub plots. The results showed that P, Fe and Zn levels had significant effects on grain yield, number of pod per m2 and 100 seed weight. Interaction effect of P and Fe was significant on biological yield, grain yield, 100 seed weight and number of pod per m2. Also interaction effect of P and Zn was significant on grain yield. Interaction effects of P, Fe and Zn were significant on grain yield, 100 seed weight and biological yield. The maximum grain yield was obtained from P3F3Z3 treatment with grain yield 1228 kg/ha. It seems P3F3Z3 treatment is optimum amount for chick pea (cultivar ILC482) under the study condition.

To evaluate the effect of row spacing and seed rate on grain yield and agronomical traits of common bean cultivars, a split factorial experiment based on the complete randomized block design with three replications was conducted at Rice Research Institute of Iran (Rasht) in 2008 and 2009 cropping years. Experimental treatments were row spacing in three levels of 20, 30 and 40 cm as main plot and seed rate in three levels of 70, 90 and 110 kg/ha and common bean cultivars including ‘Khaldar ghermez’ and ‘Kiashahri ghermez’ cultivars as sub plots. Maximum grain yield was obtained from the second year, row spacing of 20 cm, ‘Khaldar ghermez’ cultivar and seed rate of 110 kg/ha with averages of 1478.8 kg/ha, 1396.3 kg/ha, 1398.8 kg/ha and 1414.1 kg/ha, respectively. Seed rate of 110 kg/ha also had maximum protein yield (334.0 kg/ha). Based on the results, the use of narrow row spacing, more seed rate and ‘Kkhaldar Ghermez’ cultivar is better for planting common bean in the experiment region due to high grain yield and early maturity.

To investigate effects of different super absorbent polymer and animal manure ratios on the quantitative and qualitative characteristics of soybean under drought stress, a split plots experiment was conducted based on randomized complete block design with three replications in Marvdasht, Iran in 2009. Main factor included of irrigation with 50, 100 and 150 mm evaporation from pan class A and sub factor included of control, 40 t.ha-1 animal manure, 200 kg.ha-1 super absorbent polymer, 50 percent super absorbent polymer + 50 percent animal manure, 65 percent super absorbent polymer + 35 percent animal manure and 35 percent super absorbent polymer + 65 percent animal manure. The results showed that, number of pod and grain per plant, 1000 grain weight, grain yield, biological yield, protein yield and oil yield were decreased by drought stress occurrence and were increased with super absorbent polymer and animal manure application. The highest yield (2148.3 kg.ha-1) was obtained in control treatment. Results showed that the combinations of super absorbent polymer and animal manure significantly increased grain, biological, oil and protein yield compared with control. Finally, combination of 35 percent super absorbent polymer and 65 percent animal manure was the best treatment in this experiment.
