“…Further research would be needed to enlarge the diversity of the genotypes to screen and clearly identify if specific traits are better adapted to agroforestry systems. Other perspectives studies would also need to integrate other factors than the light resource, including a more global analysis with the environmental, social and economic aspects of the agroforestry system proposed (Rodenburg et al . 2022).…”

“…Despite the growing interest in rice-based agroforestry systems (Wangpakapattanawong et al 2017;Rodenburg et al 2022;Masure et al 2022), the diversity of rice response to fluctuations in radiation as well as low light remains unexploited. Up to now, varietal improvement programs in rice have focused on the selection of productive materials in full sun conditions.…”

Climatic hazards affecting the main rice producing regions of Indonesia increase the risk of annual production loss and encourage the development of innovative strategies to maintain stable production. Conversion of oil palm monocultures to rice-based intercropping systems is a strategy to be considered, but relies on the existence of suitable planting management that optimizes both palm productivity while providing enough light for undergrowth rice varieties tolerant to shady conditions. This paper proposes to couple a model of light interception on virtual canopies with indoor experiments to evaluate the feasibility of developing rice-oil palm agroforestry systems. We first selected a planting design that optimized the transmitted light available for rice using a functional-structural plant model (FSPM) of oil palm. Secondly, we reproduced the light regime simulated with specific changes in the intensity and the daily fluctuation of light in controlled conditions. Three light treatments were designed to test independently the effect of daily light quantity and the effect of diurnal fluctuation on contrasted rice subpopulations. Light quantity was the main factor driving changes in plant morphology and architecture, while light fluctuation only appeared to explain variations in yield components and phenology. This study highlighted the importance of light fluctuation in the grain filling process and resource reallocation. The conservation of relative change among varieties between treatments suggests that varietal responses to low light are likely to be heritable, and that varietal screening under full light can provide clue on varietal behavior under low light. However, the identification of specific traits such as a limited expansion of leaf area and a conservation of leaf senescence under shade and high light fluctuation paves the way for selecting varieties dedicated to agroforestry systems. Further investigations including light quality and larger genotypic population to screen are discussed.

“…Most rice worldwide is produced under the irrigated system, while only about 8% of rice is produced in the upland (Saito et al 2018). In some countries, upland rice is grown as intercrop in between trees, implementing the agroforestry concept (Ghauhan et al 1994;Hondrade et al 2017;Singh et al 1997;Rodenburg et al 2022;Wangpakapattanawong et al 2017). Intercropping rice in plantations is a common cropping practice aimed at increasing the efficiency in using available land resources and labor (Wangpakapattanawong et al 2017).…”

“…Major abiotic constraints in upland rice cultivation include drought, soil acidity, and low soil fertility (Bernier et al 2008;Haefele et al 2014;Saito et al 2018). Low light intensity becomes an additional problem, particularly for upland rice grown as an intercrop (Rodenburg et al 2022). Shading from the plantation canopy in the intercropping system reduces light intensity which is essential for the growth and development of rice plants (Vandenbussche et al 2005;Wang et al 2015).…”

Rice cultivation as intercropping in plantations is a potential approach to increase land resource efficiency. Implementation of rice intercropping would require genotypes adapted to shaded environments. This study aimed to clarify the interaction of genotype and environment on agronomic characteristics of upland rice grown under intercropping system and to identify suitable genotypes for this particular cropping system. Multi-location trials evaluated twelve upland rice lines and two check varieties in eight upland sites during the wet season (WS) 2015-2016. Rice was grown as intercropping in six sites and as monoculture in two sites. Rice as intercrop was cultivated in between plantations of tall coconut, rambutan, teak, albizia, and natural rubber. The result of this study revealed that the interaction between genotype and environment was significant for all agronomic characteristics. The genotype B12056F-TB-1-29-1 was the best performer when grown as intercropping in Subang and Indramayu, with shading intensities of 65% and 44%, respectively. The genotype B11908F-TB-3-WN-1 was the best yielder in Cianjur and Lampung Tengah, which had 37% and 54% shading intensity, respectively. The genotype B12825E-TB-2-4 was the best performer in Lampung Timur with shading intensity of 45%, while Jatiluhur was the best genotype in Banyumas with shading intensity of 82%. The yield of rice genotypes grown as monocultures was higher than as intercropping. Among the genotypes, B12056F-TB-1-29-1 showed the highest yield across sites. Stable and high-yield genotypes identified from this study are expected to be adopted by farmers for intercropping rice cultivation.
