Read More Abstract Background and ObjectivesHigh degree of evaporation from soil surface (due to high temperature of environment and low relative humidity), poor soil organic content and instability of soil structure are considered indicators of arid regions of Iran. It seems that in a regional management, conservation of plant residues with irrigation operations in the absence of a negative effect on yield can be used as a way to improve the above-mentioned conditions. The management of plant residues has been interesting to researchers in recent decades due to its various effects on the physical, chemical and biological properties of soil. On the other hand, protective tillage can help to maintain more soil moisture, reduce erosion and less use of agricultural machinery, thereby achieving sustainable agriculture and reducing costs. This research was conducted to investigate the effect of application of wheat residues and green manure along with different tillage systems on corn. Materials and MethodsThis experiment was conducted in Shush, Khuzestan Province in 2015-2016, as strip-plot in randomized complete block design with three replications. The main treatment consisted of conventional and minimum tillage methods. The sub-plot treatment applied mulches such as wheat residue, two types of green manure (mung bean (Vigna radiata L.) and cowpea (Vigna unguiculata L.)) and control (no fertilizer application). The characteristics in this research included grain yield, biological yield, number of rows in corn, number of kernels per row, 100 grains weight, and weed growth indices (density, variety and dry weight in two stages: 4 to 6 leaf and maturity of corn). ResultsMaximum grain yield of corn was obtained in wheat residue (10399.27 kg ha-1). Also, there was no significant difference in plants treated with green manure of cowpea (10013.49 kg ha-1). The lowest economic yield was seen in control (7382 kg ha-1). Similar to grain yield, the highest biological yield of corn occurred with application of minimum tillage (16139.14 kg ha-1), wheat residue (17170.89) and cowpea green manure (16790.37 kg ha-1). Besides, the best treatment to reduce the number, variety and dry weight of weeds, was achieved with green manure in minimum tillage. Based on the results, the dominant weed of the field in conventional tillage in 4 to 6 leaf stage was physalis (Physalis alkekengi) while it was common purslane (Portulaca oleracea) in the minimum tillage. In maturation of corn, both in conventional tillage and minimum tillage, the dominant weed was physalis, which had the highest dry weight of weeds in every stage. DiscussionBased on the results of this research, application of wheat residues and cowpea green manure combined with minimum tillage can be a suitable way to increase corn yield and reduce weed diversity and biomass in sustainable agriculture.

Read More Abstract Background and Objectives Chickpea(Cicer arietinum) is one of the most important Pulses in arid and semi arid regions. This plant needs a lot of nutrition such as phosphorous and Zinc elements. Most of the soil of arid and semi arid regions does not have phosphorous and Zinc nutrition sufficiently.These elements are effective for growth and yield of two chickpea cultivars. On the other hand, increasing one of them decreases the other one in plant; therefore, it is necessity to determine the amount of phosphorous and Zinc fertilizers. Materials and Methods The trail was conducted based on factorial split plot in randomization block design with three replications. We considered the two chickpea cultivars(Arman and ILC482) as the main plot and sub plot including phosphorous (P2O5) from super phosphate triple source in three levels (P1=32, P2=46 and P3=60 Kg.ha-1) and different amounts Zn from Zinc solphate source in three levels (Zn1=0, Zn2=2.5 and Zn3= 5Kg.ha-1) in Borujerd Agriculture research station where there are cold winters and humid summers.This experiment was performed in 2004. Results The result indicated a significant difference between Arman cultivar with seed yield and biological yield 2606 and 4341 Kg.ha-1 respectively and ILC482 cultivar with seed yield and biological yield 1662 and 2779 Kg.ha-1 respectively. Effect of phosphorous fertilizer on seed yield ,biological yield, number of seed per pod and number of main branch was significant and the most difference was obtained with 60 Kg.ha-1 P2O5. Effect of Zinc fertilizer on seed yield, biological yield, number of seed per pod, number of pod per plant, and number of main branch was significant and the most was obtained with 5 Kg.ha-1 Zn. The most amount of protein in seed was obtained with 60 Kg.ha-1 P2O5 and 5 Kg.ha-1Zn (P3Zn3 treatments). There are a negative correlation between amount of phosphorous consumption and Zn concentration in seed and amount of Zn consumption and P concentration in seed. Discussion Phosphorous and Zinc fertilizers are effective in root extention and decrease of pH in arid regions soils respectively. Therefore these fertilizers increase water absorption and nutrition elements including Phosphorous and Zinc in soil. In this experiment, Chickpea have positive response to application of phosphorous and Zinc fertilizers and consumption of these fertilizers, increase quantitative and qualitative characteristics of Chickpea. Therefore using 60 Kg.ha-1 P2O5 and 5 Kg.ha-1 Zn for Chickpea crop in similar regions this in expriment is recommended.
