“…Dry matter percentages of leaves, stem and ears were recorded variable among maize genotypes Millner et al, (1996), Islam et al, (2019) and Nazli et al, (2019). Also, percentage of leaves DM, percentage of stem DM, percentage of ears DM and percentage of husks DM increased with growth progression from emergence to maturity Koca and Erekul (2016) and Neumann et al, (2020). According to Millner et al, (1996), the percentage of leaves DM, percentage of stem DM was not affected with the increase in plant population density.…”

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.

“…Similarly, there was a significant difference between the average proportions of marandu grass in the ensiled mass, 2.9 and 7.8%, respectively, when the corn was harvested at the 1/4 milk line stage and at the kernel maturity stage; these values are in line with those observed for the DMY of the grass in both harvest stages. Neumann et al (2020), in evaluating corn hybrids for silage, found an average of 39 and 46% of grain in the plant dry mass, respectively, at the 1/4 milk line and kernel maturity stages. Costa et al (2017), in evaluating three maize cultivation systems for whole-plant silage (single-crop, corn intercropped with marandu grass and corn intercropped with Tanzania grass), did not find a significant difference in the percentage of grains in the plant dry mass, with means ranging from 36.8 to 41.1%; these values are lower than the findings in this study.…”

The objective of this study was to evaluate the yield and nutritional value of silage made from corn intercropped with marandu palisadegrass (Urochloa brizantha cv. Marandu) in an integrated crop-livestock system. The corn was harvested at different maturity stages and cutting heights and was processed or not before ensiling. The experimental design was a randomized block with four replications in a 2x2x2+1 factorial scheme. The treatments were composed of silage corn intercropped with marandu palisadegrass harvested at two cutting heights (20 or 45 cm) and two stages of maturity (1/4 of the kernel milk line or kernel physiological maturity) and subjected to two methods of processing (crushing or not crushing). A control treatment composed of conventionally grown corn silage was also included. The total dry matter yields of both crops did not differ significantly among treatments, demonstrating the viability of the intercropping system for both forage species. Although the dry matter content of the corn plants was higher at the time of ensiling, the fermentative and nutritive quality of the silages was not affected. Increasing the cutting height increased the grain content of the forage mass and also avoided harming the development of the intercropped grass. The silages from the physiological maturity treatment and from the processed treatment had the best quality.
