“…The higher corn causes shading in soybeans, so the specific leaf area is higher than shadeless soybean leaves in monocultures. The specific leaf area may increase with light intensity [23] [24], but in another research, the specific leaf area increases precisely in shaded conditions [1]. Light affects plant growth and development by affecting the physical appearance of one leaf as well as the appearance of the whole plant [34].…”

“…Shading on intercropping can cause morpho-physiology changes in soybeans, such as increasing specific leaf area and size but lowering stem diameter and total plant dry matter [23]. The intensity of shade intercropping soybeans with corn by 75% increased plant height and specific leaf area, but there was a decrease in the number and area of leaves, the rate of light absorption, the rate of photosynthesis, the chlorophyll index of leaves, the number of filled pods and the weight of seeds per plant [24].…”

Soybean is Indonesia’s important food crop, generally grown in monoculture. Global climate change can affect unfavourable environmental conditions and reduce soybean yields. Soybean yields can be increased by intercropping, which can improve the plant’s environmental conditions. One of the crops that can be intercropped with soybeans is corn because planting corn between soybeans can create a favourable microclimate for soybeans. This study aims to obtain the right population proportion in soybean and corn intercropping based on physio-morphological responses. This research was conducted in Kasihan, Bantul, Yogyakarta Special Region, in July-November 2021, with a single-factor experimental method arranged in a single plot design. The treatment was the proportion of soybean and corn population, consisting of 4 proportions, i.e. 2:1, 3:1, 4:1, 5:1, and monoculture soybean and corn as controls. The variables observed were leaf area, dry weight, chlorophyll content, stomatal density, number of pods, seed weight, and soybean yield. The results showed that the proportion of soybeans and corn intercropping population did not affect chlorophyll content and stomata density. A population proportion of 3:1 produces the number of leaves and specific leaf area, the number of pods, and pod weight per plant higher than monoculture soybeans and other intercropping population proportions.

“…The growth is closely related to the potential interaction of soybean plants with the environment [10]. The results showed that shade intensity up to 75% increased plant height and leaf area specifically [14]. This shows that the level of shade can cause plants to experience etiolation directly, but plants with a good tolerance level to shade can grow normally, without experiencing damage to physiological processes.…”

The conversion occurrence of agricultural land has a significant effect on the decline in soybean production, so that the use of coconut land with a double cropping system to increase national soybean production. Soybean cultivation in agroforestry systems can be applied to soybean cultivation systems under shade with shade-tolerant varieties. This study aims to determine the growth and yield of soybean varieties at various levels of shade of coconut trees. The research was carried out in Paru Keude Village, Bandar Baru District, Pidie Jaya Regency, Aceh, carried out in April – September 2019, with a Split Plot Design. The main plot is shade (N) consisting of no shade (N1), 25% shade (N2) and 50% shade (N3), and the variety plot (V) consists of Dena 1 (V1), Anjasmoro (V2) and Fan Red (V3). The study was analyzed by ANOVA, if the F value was greater than the value in the F table, it was continued with Duncan's Multiple Range Test at a significance level of 95%. The results showed that the Kipas Merah variety had higher plant height than Dena 1 and Anjasmoro, but Dena 1 had higher production at each shade level compared to Anjasmoro and Kipas Merah. Thus, the Dena 1 variety was able to maintain production at all shading conditions.

“…According to [24], lack of light due to shade changes plant morpho-physiology, such as increasing specific leaf area, stem length and leaf width, but on the other hand decreases stem diameter and total dry matter. [28] stated that up to 75% shade increased plant height, leaf area, light absorption rate, photosynthesis rate, leaf chlorophyll index, number of filled pods, and seed weight per soybean plant. In general, the rate of increase in plant height was due to the lengthening of the stem segments (etiolation) according to the research of [17].…”

Problem is that the sunlight passing through the coconut canopy is limited for photosynthesis. The purpose of this study was to measure the performance of the Anjasmoro variety technology package among coconuts. This research was conducted in North Minahasa in 2018. Field trials to test soybeans under the shade of coconut and without shade. Each treatment was repeated at 15 blocks. Technology Package The technology tested included soybean seeds planted at 15 x 40cm spacing. Basic fertilization is applied 50 kg urea, 75 kg SP36 and 150 KCL / ha. Pest or disease control follows the concept of integrated pest control. The data collected included agronomic performance and yield. The collected data were statistically tested using T (test). The results of the analysis showed that the plant height of 70.6 cm Anjasmoro variety was not significant with soybeans planted on land without shade. But the number of branches (2.1) was significantly lower than the soybean without shade. The number of soybean pods under the shade of 32 pods of coconut was lower and significantly different from the soybean without shade. The soybean yield among the coconuts was 900 kg/ha lower than the soybean without shade, 1,315 kg/ha.

Abstract: ABSTRACT. Intensity and quality of sunlight received by plants AI26-1114-8-28 and IIj9-299-1-4 were considered as shade-tolerant up to 75% shade based on the stress index tolerance value (ITC).
