“…Luminous stress suffered by soybean cultivars in the ICF system causes all genotypes to choose to allocate more photoassimilates for the growth of the stem in height, in detriment to the diameter, as an alternative to capture light, aiming to maintain their photosynthetic activities. Similar results were found by Zhang, Smith, Weiguo, Chen, and Wenyu (2011); taller plants and smaller hypocotyl diameters were obtained in the shade treatment. In a system of intercropped soybean-corn production, soybean plants under shade increased in height and had thinner stems, seeking to improve access to light (Yang et al, 2014).…”

“…However, this is not a certainty since depending on the light availability in the understory, shaded plants may have Acta Scientiarum. Agronomy, v. 45, e57497, 2023 different response patterns that can be additive, synergistic, or antagonistic (Zhang et al, 2011). It occurred in the ICF between soy and macauba, although the plants produced in the system had the alterations in the morphological characteristics of plants produced in shaded environments, such as higher heights of the aerial part and smaller diameters of the collection, the plants did not have the same response in the physiological characteristics of leaf chlorophyll content.…”

There is currently a lack of information in the literature on the integrated production of macauba (Acrocomia aculeata) and soybean (Glycine max) crops, and the importance of expanding integrated production systems; therefore, the objective of this work was to identify the effects of macauba shading on growth, development, and productivity of different soybean cultivars. The experiment was carried out in a randomized block design in a factorial scheme (4 × 2), with four cultivars and two production systems (monoculture and crop-forest integration), and four replicates per treatment. All soybean cultivars in the crop-forest integration system showed plant stagnation due to the shade level of the palm trees, as well as a reduction in the leaf area index and chlorophyll content in the leaves. Regarding reproductive parameters, grain, and oil yield, the cultivars responded differently between the production systems, revealing an interaction between the genotype and the environment. Our methodology was not favorable to soybean production; therefore, the management of spacing between palm trees and the selection of soybean genotypes that are more adapted to shaded environments are strategies that can allow for the integrated production of these species.

Phenotypic performance of a genotype is not similar from season to season depends on the environment condition such as amount and time of water availability. Objective of this study was to identify soybean promising lines with high yield on acid soil in two planting seasons. The research was conducted in rainy season 2009 and 2010 at Sitiung Research Station, West Sumatera, Indonesia. The soil of the experimental field is Ultisols with pH (H 2 O) 4.3, exchangeable-Al 3.92 me/100 g, and Al saturation 56.48%. The experiment was arranged in randomized completely block design with four replications. Result showed that the average of seed yield in RS 2010 was higher than that in RS 2009. Water supply was very important in pod filling period, plant height, filled pod, flowering and maturity days that may lead the seed yield performance. Based on the average of yield in two planting seasons, there were two genotypes having seed yield higher than the highest check variety, i.e. genotypes of SC5P2P3.23.4.1-3-28-3 and SC5P2P3.23.4.1-5. Therefore, these two genotypes are possibly to be released as new acid-tolerant varieties or can be served as new genetic materials for developing acid-tolerant variety.

“…Plants are usually exposed to several stresses simultaneously under field conditions, with limit of light and water availability being the main environmental factors affecting relay strip intercropping soybean. These stresses may cause a variety of plant responses which can be additive, synergistic or antagonistic (Zhang et al, 2011). Water stress causes membrane damage, and stimulates molecular signal transduction and hormone activation (Knight and Knight 2001), leading to a reduction in plant growth and productivity (Saranga et al, 2001;Showler and Moran, 2003).…”

Some leaf characteristics and yield of soybean were investigated under different light interception (25, 65 and 100% of sun light) and irrigation treatments (I1, I2, I3, I4 for irrigation after 60, 90, 120 and 150 mm evaporation from class A pan, respectively) in 2011. The experiment was arranged as split plot based on randomized complete block design in three replicates. Membrane stability index decreased with increasing shading. However, leaf water potential, relative water content and leaf area index under all irrigation treatments increased as light interception decreased. This trend was improved as water availability decreased. Specific leaf weight significantly decreased with increasing shading under I1 and I2, but it was statistically similar for all light interceptions under I3. In contrast, specific leaf weight was increased as shading increased under I4. In general, specific leaf weight decreased with increasing water deficit. Increasing shade stress decreased grain yield per unit area under I1 and I2, but improved grain yield under I3 and I4, which is directly related with changes in leaf water potential, relative water content and leaf area index under these conditions. Therefore, shading can reduce the impact of water stresses on soybean plant performance in the field.
