“…Tiller number were the highest with 300 kg seeds ha −1 at the maturity stage, and when levels exceeded 300 kg seeds ha −1 the tiller number decreased. The seeding rate is a key management factor that influences the production and survival of tillers (Tilley et al, 2019) and tiller number per unit area is known to increase with increasing seeding rate up to a certain limit (Dai et al, 2013;Iqbal et al, 2012;Khan et al, 2000;Otteson et al, 2008), which was in accordance with our results. In the present study, the combination of the wide-space sowing method and a seeding rate of 300 kg seeds ha −1 improved tiller formation and grain yield.…”

Coordinated uptake and utilization of water and nitrogen (N) is important for high-yield and high-efficiency cultivation of winter wheat. The relationship between soil water consumption and N uptake and utilization has not previously been widely investigated. The purpose of this study was to examine the regulatory effects of different seeding rates with wide-space sowing on water consumption and N accumulation and translocation of winter wheat. A field experiment was conducted in the southeastern part of the Loess Plateau between 2016 and 2018, in which winter wheat was sown using the wide-space method (row spacing: 22-25 cm, and seedling bandwidth: 5-8 cm) and five seeding rates: 150, 225, 300, 375, and 450 kg seeds ha −1 . The results showed that soil water consumption increased significantly with an increase in the seeding rate from 150-300 kg seeds ha −1 , especially from the jointing to maturity stage of wheat growth. At 300 kg seeds ha −1 , N translocation from the leaf and stem + sheath to the grains was significantly enhanced, which increased grain N accumulation. The maximum tiller number, water use efficiency, N uptake efficiency, and partial factor productivity from applied N were all recorded at a seeding rate of 300 kg seeds ha −1 , thus, grain yield increased significantly by 6-18%. Correlation analysis showed that N accumulation from the sowing to anthesis stage, pre-anthesis N translocation, and the grain yield of winter wheat were closely related to total soil water consumption. Overall, the findings of this study have demonstrated that widespace sowing of winter wheat at a 300 kg seeds ha −1 seeding rate improved the water use efficiency and N uptake efficiency, which in turn increased the tiller number and grain yield.

“…-1 revealed remarkably least number kernels spike -1 . It was noticed that increasing seeding rate, the number of kernels spike -1 decreased Khan et al (2002). These results are in agreement with those obtained by (Iqbal et al, 2012;Said et al, 2012;Abd El-Lattief, 2014;Nizamani et al, 2014;El-Hag, 2016;Shah et al, 2016;Mekomen, 2017;Mohiy and Salous, 2018) whom reported that grain yield and its components significantly differed according to different seeding rate.…”

To determine the effects of different seeding rates and nitrogen fertilizer levels on yield and its components of six bread wheat genotypes, a field experiment was conducted at East Canal and Al Marashda Agricultural Research Stations during the 2018-2019 and 2019-2020 growing seasons. The experiment was laid out in a split-split plot arrangement in a Randomized Complete Block Design with three replications. Seeding rates (60, 80, and 100 kg fad.-1 ) were placed in the main plots, while nitrogen fertilizer levels (75,100 and 125 kg N fad. -1 ) were allotted in the subplots, whereas, the sub-sub plots were allocated to the bread wheat genotypes (Gemmeiza 12, Sids 14, Shandaweel 1, Line 1, Line 2 and Line 3). The number of spikes m -2 , 1000 kernels weight, and grain yield were significantly higher at a seeding rate of 100 kg fad. -1 as compared to other seeding rates. Nitrogen fertilizer levels affected significantly yield and its components. Grain yield and its components increased with each increment in nitrogen fertilizer level from 75 to 100 and up to 125 kg N fad -1 . Wheat is sown at a seeding rate of 100 kg fad. -1 with 125 kg N fad. -1 gave the highest number of spikes m -2 and grain yield. The interaction effects of seeding rate by genotypes and nitrogen levels by genotypes reveal the superiority of Sids 14 and Shandaweel 1 wheat cultivars in grain yield when sown at a seeding rate of 100 kg fad. -1 with 125 kg N fad. -1 in both locations.

“…This outcome also in line with [18] who explained that lower plant population levels significantly increased the number of grains per spike. Khan et al,, [45,46] concluded that by increasing seed rate the 1000-grains weight is reduced. These results are in analogy with the findings of earlier works of Arif et al, [11] who reported higher yield with seed rate of 150 kg ha -1 .…”

The main goal of this study is to determine the best plant population level of bread wheat crop by identifying the most economic-effective variety's seed size and to deliver an overview of wheat production management requirements in general and specifically in Ethiopia, comparing with current research trends as well as to make some recommendations on the appropriate seed rates for yields, and economic benefits of bread wheat. This paper reviewed that application of the optimum seed rate under ideal environment availability of which may help in improving yield and yield components of bread wheat. To optimize seed rate and plant density of wheat, some experiments have conducted so far across most wheat growing areas of Ethiopia. The field experiments were conducted in different times at Kulumsa Agricultural Research Center from July to November 2012. Quite similar field experiment was also conducted at Kulumsa Agricultural Research Center from June to 2018 cropping season, Three bread wheat varieties (Hidassie, Dendea and Shorima) representing different seed sizes of large, medium, small, respectively and four plant population levels of 250, 300, 350 & 400 plants m -2 were tested. The interaction effects of varieties seed size and plant population on grain yield showed statistically significant (p<0.01) variation, likewise biomass yield and straw yield indicated significant (p<0.05) variations. The grain yield resulted in (4.309 Ton ha -1 ), similarly biomass yield and straw yield are (11.00 Ton ha -1 ) and (5.28 Ton ha -1 ) respectively, and it suggests that these traits are generally enhanced by the genetic makeups of the variety Hidassie /large seed size. Economic analysis using partial budget procedure was performed on grain yields to determine the treatment with most profitable returns. The beneficial marginal rate of return (8.50) and benefit cost ratio (8.07) was obtained from the variety Hidassie/large seed size at a plant population of 300 seeds m -2 followed by a marginal rate of return (9.55) and benefit cost ratio (8.05) were also recorded again from the variety Hidassie/large seed size at plant population of 250 plants m -2 . So the most cost-effective variety and plant population level for farmers with low cost of production and higher benefits were identified to be the variety Hidassie/large seed size at the plant population level of 300 plants m -2 in the rain fed cropping season is identified as low cost of production with highest benefit and can be recommended for the producers of wheat crop.
