“…Adjusting row spacing is an important factor in increasing plant density [25], and modern hybrids with more upright leaf architecture allow a reduction in row spacing associated with better capture of solar radiation, which generally promotes significant increases in yield [26]. On the other hand, the nutritional value of silage can be affected by this increase in plant density [27], but it is dependent on numerous factors, including climatic conditions, plant height, and leaf area.…”

This work aimed to investigate corn crop management practices and the quality of corn silage in beef cattle farms in southern Brazil during ten years of sampling. A total of 63 farms, located in 16 municipalities in Paraná state, Brazil, participated in the study of corn crop characterization, while the corn silages were obtained from 65 farms located in 18 municipalities in the same state. A total of 49 corn hybrids were identified, with a preference for early cycle hybrids (E) and semi-hard grain type (SH). The dataset was obtained between 2011 and 2020, and the average cycle of the identified hybrids ranged from 150 ± 14 days in 2012 to 134 ± 12 days in 2019, with a maximum amplitude of 182 days in 2012 and a minimum of 99 days in 2019 and 2020. The DM content of the plant at harvest ranged from 40.1% to 45.9% between the average of the years evaluated, with an average dry biomass yield of 25 t ha−1. The analyzed silages had average levels of aNDF and ADF within the expectation (45.6% and 26.2%, respectively) but with CP content below that commonly observed in corn silages (6.9%) due to the stage of advanced maturity at harvest. Based on this monitoring, we emphasize that the production of corn silage on beef cattle farms in southern Brazil faces specific challenges, which include outsourcing the provision of harvesting services. Above all, it was clear that there were no significant advances in the results obtained over ten years, raising concerns about interventions in the process.

“…Shaalan et al, (2015), found that, total dry forage yield, increased from 45 to 75 days after sowing (3.18 to 8.42 t. ha -1 , respectively). As plant population density increased, total dry forage yield increased Soto et al, (2002), Widdicomble and Thelen (2002), Turgut et al, (2005), Subedi et al, (2006), Stanton et al, (2007), Carpici et al, (2010, Baghdadi et al, (2012), Karashin (2014), Haddadi and Mohseni, (2016) and Opoku (2017). With increasing density from 64,200 to 88,900 plant ha -1 , total dry forage yield increased by 1.6 t. ha -1 Ferreira et al, (2014).…”

An experiment was conducted in the summer season of 2019 at the Agricultural Experiment Station, Faculty of Agriculture (El-Shatby), Alexandria University, Egypt. The main objectives of this study were: (i) to trace the physiological development of maize hybrids with reference to growth parameters, and (ii) to assess yield, quality and responses of silage maize genotypes to plant densities. Eight corn hybrids were used in this study, seven were single cross hybrids three of them were white-grain: SC10, SC128, SC131 and four yellow-grain SC166, SC167, SC168, SC176 and one whitegrain three-way cross namely TWC321. Hybrids were developed by the Ministry of Agriculture, Maize Research Program, and Agriculture Research Center, Egypt. The fieldwork included two plant densities 20,000 and 35,000 plants faddan -1 i.e.; 47,619 and 83,333 plant hectare -1 , traits were measured at three development stages i.e. (35, 70 and 105 days after emergence). Spilt -plot design in a randomized complete block design, with three replications was employed. Sub-plot was 18 m 2 of six ridges each of 0.75 m width and four-meter long. Corn hybrids were distributed in the main-plots, whereas, the subplots contained the two plant densities. The results indicated that, as plant density increased from 47,619 to 83.333 plant hectare -1 , stalk diameter decreased from 24.53 to 20.91 mm, upper leaf chlorophyll content decreased from 46.45 to 42.01 SPAD, lower leaf chlorophyll content decreased from 36.74 to 31.31 SPAD, the no. of ears per plant decreased from 1.38 to 1.10 and plant dry weight decreased from 293 to 195 g plant -1 , respectively. Plant densities significantly gave similar plant dry weight after 35 days from emergence, while, low plant density (47.619 plant ha -1 ) gave the heaviest plant dry weight after 70 and 105 DAE (279 and 584 g plant -1 , respectively).The results indicated that relative growth rate of maize hybrids during the first developmental stage (35-70 DAE) was significantly superior to measured figures in the late season stage (70-105 DAE). Also, hybrids with significantly higher RGR during the early season's stage were SC10, SC128, SC131 SC168 and SC176. While SC167 and TWC321 significantly exhibited lower values. By the late season stage (70-105 DAE) all hybrids had similar values of RGR. Effect of plant density on total dry forage yield over maize-hybrids and developmental stage, the highest significant total dry forage yield was recorded at a plant density of 83.333 plant hectare -1 (15.70 t. ha -1 ), while, the plant density of 47,619 plant hectare -1 significantly recorded lower value (13.92 t. ha -1 ). Maize hybrids were significantly divided into two groups regarding protein yield.

“…On the basis of many years of research, the scientific developments and practical experience in growing maize using intensive energy-saving technology have been generalized. Much attention has been paid to improving the basic elements of technology for growing maize used for grain, silage, green fodder, as well as for food purposes and promising directions for increasing maize production in Ukraine (Chandiposha & Chivende, 2014;Haddadi & Mohseni, 2016).…”

The aim of this research is to optimize growth and development of maize for biomass by selecting maize hybrids to fulfill their productivity potential. The following maize hybrids were the subject of research: Forteza, DM Native, DM Skarb. The greatest height of plants was formed in the interphase period of milk-wax maturity of grain in hybrid Forteza -286.4 cm. In hybrid DM Native the height of plants was -271.2 cm, hybrid DM Skarb -263.6 cm. Weight of one plant of hybrids studied during the maize growing season ranged from 442 g to 760 g. Thus, the largest mass of maize plants was recorded in the milk-wax maturity stage. It was the largest at the hybrid Forteza and amounted to 760 g, that is more than at the hybrid DM Native for 3.4% (26 g) and at the hybrid DM Skarb for 6.6% (50 g). The average crop yield of the hybrid Forteza for the period of research was 55.1 t ha -1 . Hybrids DM Native and DM Skarb provided this indicator at the level of 50.6 and 45.7 t ha -1 respectively. Hybrid Forteza provided a maximum crop yield 55.1 t ha -1 with plant height 286.4 cm, assimilation surface of one plant and a crop 0.59 m 2 ; 42.8 thousand m 2 ha -1 and plant weight 760 g.
