“…Soybean yield is highly dependent on the number of pods produced, which is an indicator of the plant's health. The NPP results soybean varieties Setiawan et al, (2023), highlighting the significance of this finding. Studies by Pedersen & Lauer, (2004) showed that adjusting sowing dates can increase pod and seed quantity, and Adetokunbo et al, (2019) also highlighted the importance of pods and seeds per plant in soybean seed production.…”

Soybean (Glycine max), an economically significant legume originating from East Asia, serves as a valuable source of protein and oil globally. In Pakistan, soybean is considered a non-conventional oilseed crop, with successful cultivation possible during both the spring and summer seasons. The careful selection of appropriate varieties is a primary concern for soybean growers in the country. Therefore, experiments were conducted utilizing the newly developed varietal line in the agroecological zone of Tandojam to select the most suitable and adaptable varieties. A total of forty-six newly developed varietal lines, which have not yet been released, were evaluated alongside four released varieties (Ajmeri, Faisal, Jack, and Rawal) that are already being cultivated in various regions of the country. The field experiments were carried out at the experimental area of the Nuclear Institute of Agriculture (NIA) in Tando Jam during the spring and summer seasons of 2018. Agronomic traits were recorded for each variety, and weather data were obtained from the Pakistan Meteorological Department. All agricultural practices were followed. The results indicate significant variations among the genotypes for all evaluated characteristics. Based on grain production, NIBGE32 exhibited the highest performance, achieving a notable yield of 22g during the summer season, which was 30% higher than the yield of the top-performing control variety, Faisal. Other newly developed varietal lines, namely NIBGE 18, NIBGE 8, NIBGE 45, and NIBGE 41, also demonstrated promising high-yield potential. These varieties displayed comparatively superior growth and yield outcomes. Germination percentage significantly vary in the spring and summer season (Mann-Whitney U =7925, P<0.01); whereas days to maturity, plant height, leaf area, lowest pod height, 100-grain weight, biological yield, seed weight per plant, were not significantly different in two seasons. This suggests a potential for these varietal lines to be cultivated in both seasons. This research endeavours to offer valuable insights and recommendations to farmers and policymakers, aiming to augment soybean production and advance agricultural sustainability in the region of Sindh.

“…Corn-soybean intercropping is one of the main cereal-legume intercropping systems used, and it is distributed throughout most of the world [22], including Africa [23], America [24], Asia [25], Australia [26], and Europe [27]. The effects of the intercropping system on crop yields, land use efficiency, and nitrogen fertilizer use on grain or silage corn in corn-soybean intercropping systems have been reported [22,[28][29][30]; however, studies on the intercropping of sweet corn and soybean are limited [31][32][33].…”

Corn (Zea mays L.)–soybean (Glycine max (L.) Merr.) intercropping is one of the main traditional intercropping systems used. We hypothesized that sweet corn–soybean intercropping with reduced nitrogen application could improve the crops’ fresh grain yield and nitrogen acquisition. We clarified whether sweet corn intercropped with soybean has the advantages of improved crop yield and carbon and nitrogen accumulation and assessed interspecific competition in the intercropping systems. A four-year (2017–2020) field experiment was conducted with three nitrogen application levels (0, 150, and 300 kg∙ha−1) and three planting patterns (monocropped sweet corn, monocropped soybean, sweet corn–soybean intercropping) at Jiangxi Agricultural University, Nanchang, China. The LER (land equivalent ratio), AG (aggressivity), and CR (competitive ratio) were calculated using the fresh grain yield and nitrogen and carbon accumulation of sweet corn and soybean. The LER values were greater than 1.0 in most of the intercropped patterns, except for the value based on the crops’ fresh grain yield without nitrogen application in 2020. Sweet corn had greater values of CR and AG than soybean in the intercropping system. Compared with common nitrogen application (300 kg∙ha−1), reduced nitrogen application (150 kg∙ha−1) did not significantly reduce the LER or the average CR and AG values. Under reduced nitrogen application, the values of LER, CR, and AG, based on the crops’ fresh grain yield and nitrogen acquisition, were not significantly different between the four years. In conclusion, based on the LER, CR, and AG, sweet corn–soybean intercropping had the advantage of crop yield and nitrogen acquisition, and sweet corn was the superior competitor. Sweet corn–soybean intercropping with nitrogen application (150 kg N ha−1) showed good inter-annual stability of crop productivity and competitiveness of the sweet corn.

Sweet corn is a plant that is widely grown in Indonesia because it has advantages over corn in general. Sweet corn is generally grown in monoculture, which has several disadvantages. Sweet corn can be planted intercropping, and cowpea are one plant that can act as an intercrop. This research aims to determine the dynamics of environmental conditions in various proportions of sweet corn and cowpea intercropping populations. This research is an experimental study with a single factor arranged in a complete randomized block design with three blocks as replications. The treatment is the population proportion of sweet corn and cowpea, consisting of 3 proportions, namely 1:1, 1:2, and 1:3. Monoculture sweet corn and cowpea were also planted for comparison. Monoculture sweet corn is planted with a spacing of 75 cm × 25 cm; Cowpea are planted at 25 cm × 25 cm, while intercrops are planted at a spacing according to treatment. Observations were made on light intensity, extinction coefficient, air temperature, air humidity, wind speed, soil moisture, soil temperature, and water content. The results showed that intercropping sweet corn and cowpea with population proportions of 1:1, 1:2, and 1:3 caused a decrease in light intensity, a reduction in wind speed, a decrease in air temperature, and an increase in air temperature and humidity. The population proportion of sweet corn and cowpea 1:3 results in better abiotic environmental conditions. Farmers can use the results of this research if they want to plant sweet corn by intercropping with cowpea with a population proportion of 1:3.
