Effect Of Different Packaging Treatments Of Urea Fertilizer And Equal Agricultural Distances Between Lines And Plants On The Yield Of Sunflower

Abstract

A field experiment was conducted in Al-Majd Umm Al-Akf sub- district ((9 km away from the center of Al-Muthanna Governorate), during the spring season 2021 to study the effect of four different packaging treatments for urea fertilizer and four distances for planting between lines and plants on yield characteristics. The experiment was applied according to the arrangement of split plots design. Using a randomized complete block design (R.C.B.D) with three replications, the planting distances were filled with (40 ×40), (50×50), (60×60) and (70×70) for the main plots, while the packaging parameters (Zeolite + cement) were set. And (white cement only), (zeolite only) and regular (comparative) urea in the secondary plates (sub plot). The results of the analysis showed the significant effect of planting distances between lines and plants, as the distance (70×70) was superior to the characteristics of the weight of a thousand seeds and the yield, the individual plant gm plant-1 78.00 gm and 78.48 gm plant-1 respectively. While the distance (40×40) was superior by giving the highest mean for the characteristic of total seed yield of 3.81 t ha-1. The weight of a thousand seeds was 79.92 g, while the distance (70×70) and the packaging treatment (zeolite only) outperformed by giving the highest mean for the trait of the yield of the individual plant gm plant-1 it reached 80.30 gm.
