Effect of spraying Benzyl adenine (BA) and adding nitrogen fertilizer on yield of Avena sativa L.

Abstract

The field experiment was conducted in the second agricultural research station located in the Al-Bandar area, which is affiliated with the College of Agriculture at Al-Muthanna University. This Study was conducted during the winter season 2022-2023 was conducted during the 2022-2023 winter agricultural season. The experiment investigated the relationship between two factors. The first factor is nitrogen, which was applied at four distinct four levels (0, 40, 80, and 120 kg N ha-1). After emergence, during the elongation stage, and at the Booting stage, nitrogen was applied in three separate batches. Benzyl adenine is the second factor examined in this study. Four Different concentrations of benzyl adenine were applied to the plant at 0, 100, 150, and 200 mg L-1. The benzyl adenine was applied in two Different concentration, with the first batch being applied during the elongation phase and the second batch being applied during the Booting phase. The application consisted of completely saturating the plant with a spray. The experiment was carried out with randomized complete block design using split plot with three replicates. The Main plots were sprayed with varied concentrations of benzyl adenine, while the Sub- plots received varying levels of nitrogen fertilization. The results showed Significant differences in the Nitrogen application, especially in the Significant of 120 kgN.ha-1 In the following characteristics (number of grains Per panicle, weight of 1,000 grains, grains yield, biological yield), it gave averages of 105.6 grains panicle-1 , 38.36 g, 6.27 ton ha-1, 25.41 ton ha-1), and at 40 kg N ha-1, it was greater than the number of panicle of 429.8 m2. The results also indicated significant effect in the spraying of Benzyl adenine and the highest average treatment of 200 mg L-1 (1,000 grain weight) and gave an average of 37.68 g The interaction between factors under study showed the combination (120 kg N ha-1 x 200 mg L-1 BA) gave averages of 41.49 g in grain weight.
