Effect of spraying of some nano fertilizers in yield of three geno types of Sorghum bicolor (L.) Moench

Abstract

A field experiment was carried out during the autumn season of 2017 in one of the farmers' fields in Qurna / Al-Ghamiej (65 km north of Basra city center) in silty clay soil at 47.27 degrees east and 30.56 degrees north latitude. The experiment was conducted on a split-plot factorial experiment with three replicate. Main plots involved the cultivars (Kafair,Al-khair and Anqath). The sub-plots involved nano - fertilizer (control (F0), 2Zn Kg ha-1 (F1),1 Kg Cu ha-1 (F2) and 2 Zn ha-1 + 1 Kg Cu ha-1 (F3) )., respectively. thereby, the number of experimental units is 36 units and the area (3 × 4) m 2 for each the experimental unit. The aim of study is evaluating effect of spray varieties of nano fertilizer on three varieties of Sorghum bicolor (L.) moench The variable studied were number of grains in the head, weight of 1000 grains (g) and the grain yield ton.ha -1 The results of the analysis showed there were significant differences among varieties in most of the studied parameters. Variety AL-Khair showed the highest values for yield components in final yield 5.74 ton ha-1. The results showed foliar application treatment F3 gave the highest number of grains in the head (1713 seed head-1), weight of 1000 grains (30.95 g ) and Grain Yield (5.9 ton ha-1) compared with nano fertilizer treatment by using each element alone and the non-additive treatment. The interaction between varieties and the addition of nano fertilizer had a significant effect on yield components. Whereas treatment of Variety AL-Khair and addition two elements together had the highest grain reached 6.77 ton.ha-1 because of its superiority in yield component compared to other combinations.
