Abstract: 

Introduction: Applying modern technology such as nanotechnology to agricultural sciences is essential.  Nanotechnology has many applications in enhancing the ability of plants to absorb nutrients (Mousavi and Rezaei, 2011). Cereals are highly important for their high dry matter production. They are, however, poor in protein content which shows their low quality and nutritive value. It is essential to use intercropping of cereals with legumes extensively to provide acceptable crop yield and quality (Ghanbariet al., 2007; Dahmarde, 2010). This study was conducted to evaluate the effects of spraying nano-iron chelate fertilizer on a pearl millet-cowpea intercropping.
Materials and methods: This experiment was conducted as a split randomized complete block design with three replications in 2015, at the research field of the Agricultural and Natural Resources of Bampour, Sistan and Baluchestan provinces. In this experiment, pearl millet is considered a main crop. Nano-chelated iron was sprayed at concentrations of 0%, 1%, 2% and 3% in two stages comprising main-plots and 5 cropping systems including: pearl millet sole culture, cowpea sole culture, 100% millet+20% cowpea, 100% millet+40% cowpea and 100% millet+60% cowpea. Evaluated parameters included plant height, leaf number per plant, one-thousand grain weight, grain yield, biological yield, harvest index and Land Equivalent Ratio (LER).
Results and discussion: Results indicated that the interaction of nano-iron chelate and cropping systems was significant on all studied traits (except leaf number of pearl millet and cowpea and LER). In addition, the effects of nano-iron chelate was significant on all studied traits, with the exception of pearl millet plant height. Mean comparison revealed that plants in a pearl millet sole culture that were sprayed with a nano-iron concentrate of 3% increased grain yield by 13 percent compared with non-sprayed plants of 100% millet+20% cowpea. Among fertilizer treatments, spraying with nano-iron at a concentration of 3% increased the grain yield of pearl millet by 46 percent in comparison with those not sprayed. Spraying a cowpea sole culture with nano-iron at a concentration of 3% increased yield by 11%, compared with unsprayed 100% millet+20% cowpea. In addition, spraying with nano-iron at a concentration of 3% increased cowpea grain yield by 43% over the unsprayed. The maximum LER (1.8) was obtained at 100% millet+60% cowpea.
Conclusion: The results of the experiment confirmed that nano-iron chelate fertilizer was effective on intercroppings of pearl millet and cowpea. Plants sprayed with concentrations of 3% had the greatest morphological characteristics and yield of both crops. Low amounts of iron in the soil along with a nano-iron chelate treatment led to increased grain yield. Due to inter-plant completion, the greatest morphological characteristics of both plant species was obtained when sown in a sole culture.
