Effect of Pluramin and iron and zinc nano-fertilizer on rainfed chickpea (Cicer arietinum L.) at on-farm conditions

Abstract

This experiment was conducted to study the effect of pluramin and iron and zinc nanofertilizers on rainfed chickpea in autumn sowing at farmer conditions. The field located next to synoptic weathering station-Varmahang in KamyaranIran during 2015-2016 growing season. The experiment layout was split plots in a randomized complete block design with three replications. The main factor were three levels of pluramin amino acid application (0, 150 g/ha and 250 g/ ha) and subplot were four levels of nano fertilizers application (control: distilled water, nano-iron, nano-zinc, and nanoiron + zinc). The results showed that characters as: number of secondary branches, number of pods, number of seeds per pod, 100 seed weight, grain yield, biomass, protein percent and protein yield were significantly affected by the application of pluramin. An application of pluramin significantly increased all traits with exception of protein percent. In this experiment, the application of micronutrients nano-fertilizers also showed significant differences on the number of primary and secondary branches, number of pods, 100 seed weight, grain yield, biomass and protein yield, as these characters were enhanced by nano-fertilizer. Finally, mutual effect of pluramin and nanofertilizers indicated that the most pod numbers, grain yield and biomass were achieved by 250 g pluramin and iron+zinc nano-fertilizers.
