Using Packaging Technology to Reduce the Fragmentation of the Added Fertilizer, Improve Growth and Increase Yield Efficiency for Varieties of Forage Barley

The experiment was carried out in one of the farmers’ fields in Muthanna Governorate, Rumaitha district, which is 25 km from the city center and for the agricultural season 2021-2022, with the aim of achieving the maximum possible benefit from the added nitrogen fertilizer (T1, T2 and T3) in addition to the treatment of comparison with ordinary urea (T4), which was added according to the recommendation of fertilizer and the possibility of reducing the infusions of its addition Their reflections in nitrogen absorption, improving plant growth and increasing plant yield in quantity and quality, for four different varieties (Samir, Burqa, Aba99, and Aba 265) of the feed barley crop, were applied according to the design of the complete random sectors (RCBD) with three repeaters. The results showed that the preliminary results for the highest averages amounted to 43.680 and 10.545 tons, and 7.80 and 8.41% for the cultivars. It reached 8.64%. Either the coated urea fertilizer fractional coefficients, the retail transaction in two batches (T2) significantly exceeded the total green and dry feed yields, with averages of 45.380 and 11.315 tons E -1 respectively, when overlapping between the two factors a discrepancy between the combinations within the overlap was observed and the combination between the two classes A265 and A99 with the retail transaction in two batches (T2) by recording the highest average of the total green and dry feed yield amounted to 52.170 and 12.077 tons E -1 for the two varieties in succession.
