Abstract

To investigate the effect of different TIMEs and CONCENTRATIONs of ZN-CHELATE fertilizer SPRAYING on corn seed (704 cultivar), an experiment was carried out in split plot in Khatam region, using a randomized complete block design with three replications. The treatments included three SPRAYING TIMEs (T1=spraying the plant with 5 to 8 leaves, T2=spraying the plant with 5 to 8 leaves at the emergence of crown flower, and T3=spraying the plant with 5 to 8 leaves at the emergence of crown flower at dough stage) in the main plot, and different CONCENTRATIONs of ZN-CHELATE (i.e. C1=zero application of Zn (control), C2=spraying 0.5 kg /ha Zn, and C3=spraying 1 kg/ha Zn) in the sub-plot. The traits under study included corn weight, the number of seeds and rows in corn, cob weight, corn length, 1000-grain weight, and seed yield. The results indicated that the aforementioned treatments had a significant effect on grain yield, the number of seeds, 1000-grain weight, and cob weight. On the contrary, corn length and weight and the number of rows were not affected. The interaction effect of the two treatments also revealed that the highest 1000-grain weight (373.3 g) obtained from 1 kg/ha Zn and T3 SPRAYING treatments. The results indicated that SPRAYING 1 kg/ha Zn significantly increased grain yield and the number of seeds in corn. The highest average of the number of corn seed and grain yield obtained from the third level of SPRAYING TIME, i.e. SPRAYING the plant with 5 to 8 leaves at the emergence of crown flower at dough stage. The highest grain yield belonged to 1 kg/ha Zn and T3 SPRAYING treatments.
