“…The increases in growth, yield and its attributes of soybean crop as a result of increasing nitrogen fertilizer level up to 120 kg N/fed can be ascribed to the role of nitrogen in protoplasm and chlorophyll formation, enhancement meristematic activity and cell division, consequently increases cell size, leaf area and photosynthetic activity, which caused increases in plant growth characters, yield and its attributes. Rashwan and Zen El-Dein (2017) confirmed these results, who stated that number of pods ,branches, seed yield per plant and per fed of soybean were increased with the increment in nitrogen level up to 120 kg/fed.

“…Soybean is considered a legume plant, which has the ability to fix atmospheric nitrogen when properly modulated, and so is less dependent for growth on sources of nitrogen from the soil (Flynn and Idowu, 2015). Rashwan and Zen El-Dein (2017) stated that number of branches per plant, number of pods per plant, seed yield per plant and per fad of soybean as well as total LER and aggressivity were increased with the increment in nitrogen level, especially with application of 120 kg/fed, while the lowest one was obtained with 80 kg/fed. In spite of nitrogen was an important fertilizer of crop production, its excessive application could result in nitrogen loss that could have serious environmental concerns (Gao, et al 2020).…”

In the field, two experiments were confirmed in 2017 in addition to 2018 seasons at Sakha Agricultural Researches Station Farm, Agricultural Research Center, Egypt, toward investigate the influence of nitrogen levels (100, 110 and 120 kg N/fed) and spraying with humic-acid levels (without , 2.5, 5.0 and 7.5 g/L) on growth, yield and its attributes, as well ear rot disease of maize under intercropping system of maize and soybean. The field trials were executed in three replicates using split-plot design. The main-plots were consigned to nitrogen levels. The sub-plots were deal out to four levels of humic-acid as foliar spraying. Growth, yield and its attributes of both maize and soybean under intercropping system were significantly improved by rising N-levels from 100 to 110 and 120 kg N/fed and the recommended one was 120 kg N/fed which led to decrease ear rot disease infection and severity. Spraying with humic-acid (7.5 g/L) produced highest growth, yield and its attributes of both maize and soybean under intercropping system and caused more reduction in ear rot disease infection and severity. It can be recommended that the maximum growth, productivity, land equivalent ratio (LER), relative crowding coefficient (RCC), total income (LE), i.e.10588.60 and 11032 LE, respectively, economic return (LE) and lowest ear rot disease infection and severity (in maize) under intercropping system of both soybean and maize were obtained from spraying with humic-acid (7.5 g/L) and fertilizing with 120 kg N/fed beneath the environmental circumstances of Kafrelsheikh Governorate, Egypt.

Intercropping of corn and soybean is widely practiced in agricultural production. However, few studies have investigated the effect of intercropping and fertilizer reduction on soybean yield. In the present study, corn and soybean were interplanted in 2:2, 2:3 and 2:4 ratios. Two fertilizer levels (normal: 600 kg/ha VS. reduced: 375 kg/ha) were set. The effects of fertilizer levels and intercropping planting patterns on the growth and yield of intercropping soybeans were studied based on the changes in enzyme activities related to nitrogen metabolism and insect community in the field. The results show that fertilizer reduction significantly reduced the biomass, 100-seed weight and yield of soybean. Intercropping also reduced these yield-related traits; a decreasing trend was more obvious with a decrease in soybean ratio. Intercropping had greater effect on soybean plant biomass, 100-seed weight and yield than fertilizer reduction. Reduction in fertilizer reduced the activities of nitrogen-metabolism-related enzymes in soybean. In addition to increased NR (nitrate reductase) enzyme activity in R5, intercropping planting pattern also had negative effect on the activities of nitrogen-metabolism-related enzymes in soybean. Reduced fertilizer only significantly reduced the Pielou evenness index. Reduced fertilizer application was beneficial with respect to the outbreak of greenhouse whitefly. However, an intercropping planting pattern can significantly increase the number of species, as well as the Shannon–Wiener diversity index and the Pielou evenness index of the insect community, and significantly reduce the Simpson dominance index and the population of the most important pest, green leafhopper. In conclusion, C2S4 (two corn rows with four rows of soybean) is a scientific intercropping planting pattern that can reduce the occurrence of pests through ecological regulation and does not significantly reduce the activity of enzymes-related to nitrogen metabolism in most cases, ensuring soybean yield.
