Effect of row spacing and spraying of complete nano-fertilizer on growth and yield of Wheat (Triticum asetivum L.).

Abstract

A field experiment was conducted during the winter season 2018-2019 at Al- Qurna site to investigate the effect of row spacing and spraying of complete nano-fertilizer on growth and yield of Wheat (Triticum asetivum L.). The experiment was arranged in a split-plot by using R.C.B.D design with Three replicates, the main-plots were row Spacing (10, 20, and 30 cm), the sub-plots included Nano-fertilizer levels (0, 2.5, 3.5, and 4.5ml. L-1). Results showed that the row spacing gave higher value for most characters, the distance 30 cm rat gave plant height and flag leaf area, 1000 grain weight, grain yield, and bio yield, as they were (88.67cm, 46.02cm2,45.69g, 7.86 t. h-1, 21.37 t. h-1), respectively. Treatment of fertilization with nano spraying with a concentration of 4.5 ml. l-1 was significantly superior in most indicators of growth and yield, it gave the highest averages compared to other fertilizer levels in plant height, leaf area, weight of 1000 grains, grain yield, number of spikes, number of tillers reached (89.23 cm, 47.30 Cm2, 44.87 g, 7.96 t. ha-1, 650.22 spikes. m2, 750.56 tillers. m2) respectively. The interaction between factors was significant in most of the growth indicators in two components of yield (number of spikes and number of spike seeds) in addition to the biological yield.

Effect of Distances Between Lines and Levels of Nitrogen Fertilizer on Yield and Quality Characteristics of Wheat

“…The results in Table (6) show the significant effect of planting distances on the trait of biological yield, as the distance exceeded 30 cm with the highest average for this trait amounting to 6.90 tons ha -1 and without significant difference from the distances 15 and 25 cm, which gave averages of 6.41 and 6.30 tons ha -1 Respectively, while the distance of 20 cm gave the lowest average for this trait amounting to 5.76 tons ha -1 , and perhaps the reason for this is due to the superiority of this distance in the number of tillers, which are considered to be the components of the biological yield, with no significant difference in the second component of the biological yield, which is the grain yield. This conclusion was consistent with the findings of [11,12,17], who all found statistically significant changes in the rate of biological yield based on planting distance.…”

“…To increase the number of plants m -2 and thus increase the number of spikes, in addition to the small distances between plants led to an increase in the number of lines and thus reduce the amount of seeds per line, which reduced the competition of plants among themselves and thus increased the number of spikes. This result agreed with [10][11][12] ,who confirmed the existence of significant differences between planting distances in the number of spikes per unit area.…”
