“…These results may be due to plants irrigated with 1.2 or 1.0 of ETo produced greater canopy therefore had greater light intercepted and low light intensity%. These results here were accordance with those obtained by Loomis and Connor (2002), Langeroodi et al (2014) and Adeboye et al (2016).…”

“…Maximum crop production requires complete capture of incident solar radiation and can only be achieved with supporting sufficient levels of water and nutrients (Loomis and Connor, 2002). Plants irrigated at low water depletion of the total available soil water produced greater leaf area than plants irrigated at high levels of water depletion and therefore had greater intercepted photosynthetically active radiation (Langeroodi et al, 2014;Adeboye et al, 2016). Water stress and shading contribute to reduce legume component yield under intercropping (Lesoing and Francis, 1999).…”

Effective intercropping pattern, use of highly efficient irrigation system and proper irrigation scheduling are one of the current challenges in agriculture sector for saving water, maximizing crop production and economic benefits. Thus, a two-year field experiment was conducted at Ismailia Research Station (30o 35' N latitude, 30o 26' E longitude, 20.0m above MSL), Egypt during the two growing seasons of 2016 and 2017 to study the effect of three irrigation treatments (1.2, 1.0 and 0.8 ETo calculated by the BIS model) and five peanut/sunflower intercropping patterns ((P1 = 100% peanut + 25 % sunflower), (P2 = 100% peanut + 33% sunflower), (P3 = 100% peanut + 50% sunflower), (P4 = sole peanut), and (P5 = sole sunflower)) on yield and its components of both crops, applied irrigation water, consumptive use, land and water productivity and net income. The experimental layout was designed in strip plot with three replicates. The results indicated that light intensity percentage significantly decreased with the 1.2 ETo treatment. The highest values of growth and yield of pod, seed and oil of peanut and sunflower were detected with the application of 1.2 ETo. Intercropping sunflower with peanut significantly reduced the yield of both crops in both seasons. However, intercropping sunflower at low density (P1) recorded the maximum values for yield and yield components of peanut, compared to the P2 and P3 treatments. The highest values of applied water (451 and 439mm) and consumptive use (403 and 415mm) were obtained in the first and second growing seasons, respectively when P3 (100% P + 50% S) was irrigated with 1.2 of ETo. Intercropping sunflower with peanut increased water use efficiency (kg/mm or cereal unit/mm) compared with sole crop. The average of water equivalent ratio was highest (1.255) produced with P3 under 1.0 ETo treatment, as average of both growing seasons. The maximum value of land equivalent ratio (1.569) and net income (L.E. 22589/ha) were recorded with P3 intercropping pattern irrigated with 1.2 of ETo treatment, on average basis of both growing seasons. Sunflower was the dominant component for the all intercropping systems, while peanut was the dominated crop. Thus, we recommend the implementation of P3 intercropping system, namely 100% peanut + 50% sunflower irrigated with 1.2 of ETo to increase land productivity in sandy soil under sprinkler irrigation or with 1.0 of ETo to save on the applied irrigation water, with yield lose were low. Under severe drought conditions, we recommended application of 0.8 ETo.

“…Van roekel and Purcell (2014), in a study conducted in Missouri, USA, found rUe values for soybean in different crop years (2012/2013 and 2013/2014) of 1.01 and 1.77 g MJ -1 , respectively. Also, other results were reported in the literature: 1.23 g MJ -1 (Schöffel and Volpe 2001); 1.31 g MJ -1 (Adeboye et al 2016); 1.44 g MJ -1 (Singer et al 2011); and 1.78 g MJ -1 (Pengelly et al 1999) for the soybean crop. The variation in the results found in the literature was probably due to the differences of the meteorological conditions to which plants were subjected.…”

In a study conducted in Nigeria by Adeboye et al (2016), the authors obtained average k values of 0.52 and 0.42 for two crop years 2013/2014 and 2014/2015, respectively.…”

An Acad Bras Cienc 91: e20180066.Abstract: Despite its economic importance, the microclimate in soybean canopies has not yet been studied in detail. Such a study can yield valuable information regarding the interaction of a crop with its environment. In this context, the aim of this study was to evaluate the solar radiation dynamic and yield responses for each canopy strata for two soybean cultivars with determined and undetermined growth habits. A field study was conducted during the 2013/2014 and 2014/2015 growing seasons in the city of Frederico Westphalen, rio grande do Sul, Brazil. The cultivar NA6411, with a determinate growth habit, presented a greater interception of radiation in the middle and lower canopies strata which results in higher soybean yield when compared to the cultivar TeC6029, and thus, can be recommended for cultivation in crop production systems. The contribution of the middle and upper canopy strata to the total yield formation was greater than that observed in the lower canopy strata due to the greater interception of solar radiation by these strata. To increase soybean yields, new studies regarding the microclimatic conditions of the soybean canopy should be developed to improve the maximum potential yield of the new soybean cultivars.

“…Moreover, the use of light in different wheat genotypes was different. It seems that the difference in photosynthetic efficiency of cultivars can differentiate the behavior of cultivars in different weather conditions, consistent with the results of several other researchers [31,32]. Sinclair and Muchow [33] reported that the effect of light consumption is more influenced by plant genetics.…”

A randomized complete block design with three replicates using 20 genotypes of rain-fed wheat was applied. Cluster analysis of different wheat genotypes segregated the genotypes into 3 groups. Comparison between the groups in the first crop year revealed that the second and third groups exhibited the highest rate of radiation-use efficiency (RUE), and the first group had the lowest. Grain yield was highest in the third group and lowest in the first group, with an average of 219.87 g/m2 and 173.40 g/m2, respectively. In the second crop year, the highest rate of RUE was reported in the first group and lowest in the second and third groups. The highest grain yield was observed in the second group and the lowest in the third group (315.40 g/m2 and 253.75 g/m2, respectively). Based on the results of the biplot, high-yield genotypes in the first year of cultivation included G14 (263.00 g/m2), G20 (264.50 g/m2), G18 (214.00 g/m2) and G19 (222.50 g/m2). Based on the results obtained by cluster and PCA analysis under stress conditions, we concluded that several traits play a role in determining the grain yield of wheat.
