“…Moreover, it may be vital for the crop to reach a certain LAI that determines the light penetration profile amount into the canopy and soil (Rahemi Karizaki et al, 2021). The leaf area expansion and development depends on various factors such as temperature, water availability, plant density per unit area, amount of nutrients available, morphological characteristics of genotypes, and crop year (due to the variety of environmental factors), which cause differences in LAI (Rahemi Karizaki et al, 2021). According to Kadam et al (2018), LAI varies with environmental conditions and sowing dates; LAI decreases under extreme sowing dates.…”

“…During the early stages of growth, the leaf expansion rate largely dictates the amount of radiation intercepted and absorbed by the plant.

Quinoa (Chenopodium quinoa Willd.) is an annual plant belonging to the Amaranthaceae family. The total accumulated incident photosynthetic active radiation (PAR) in a plant is a function of the site, year, sowing date, and phenology, whereas the amount of PAR intercepted by the plant is dependent on its leaf area index (LAI) and light extinction coefficient (KPAR). This study investigated changes in KPAR and radiation use efficiency (RUE) levels in quinoa before and after inflorescence (fruit set) color change under various temperature and light conditions through the sowing date. This study was conducted in the Jihad Keshavarzi allocated field of Khalilabad city in Khorasan Razavi province, Iran, using a randomized complete block design with three replications over two seasons, 2017–2018 and 2018–2019. Treatments included eight and seven sowing dates in the first and second season years, respectively. The results showed that the mean of KPAR was 0.66 and 0.31 in the first and second years, respectively. Also RUE in vegetative stages of development was higher than during the grain‐filling period. The mean of RUE was 2.60 ± 0.06 and 0.78 ± 0.17g/MJ in the first year before and after changing the color of the inflorescence (fruit set), respectively; these values were 2.12 ± 0.04 and 1.01 ± 0.61 g/MJ in the second year. The results indicated the base (TBRUE), lower optimum (TP1RUE), upper optimum, and ceiling temperatures of quinoa for RUE were determined to be 3, 18.8, 25.5, and 35°C, respectively.
