“…Reduced spacing between rows in a same plant density results in better plant distribution in the area. In this way, intraspecific competition is reduced due to greater equidistance between plants, and greater water efficiency (ZHOU et al, 2015). However, De Bruin and Pedersen (2008) reported that the soybean response to spacing reduction varies according to crops, localities, cultivars, sowing time, and soil management.…”

“…One of the objectives of using narrow row spacing is to reduce the time the crop intercepts most of the solar radiation, optimizing canopy photosynthetic capacity (DE BRUIN;PEDERSEN, 2008). In addition, adjusting spacing may change root distribution in the area, water use efficiency, weed competition (ZHOU et al, 2015), morphology CHERNEY, 2011;WERNER et al, 2017), and soybean yield (HANNA et al, 2008). Some recent research showed that the effects of reduced spacing on yield vary according to cultivars and sowing time, with positive effects on indeterminate cultivars that are quite compact and sown at the beginning of the harvest PROCÓPIO et al, 2014).…”

Modifications in plant spatial arrangements, such as the use of narrow rows, twin rows, and crossed rows, may favor the development and productivity of soybeans due to the morphophysiological changes occurring in the plants. The aim of this research was to assess yield components, mortality rate, harvest index, and the yield, of two soybean cultivars, with indeterminate growth habits, in response to alternative plant spatial arrangements. The experiment was conducted in Londrina, Paraná State, Brazil, in the 2013/14 and 2014/15 growing seasons, with randomized complete block design, in a 4 × 3 × 2 factorial scheme, with three replications. The treatments were composed of four row spacings, at 0.2 m (narrow rows); 0.2/0.8 m (twin rows); 0.5 m (traditional); and 0.5 m (crossed rows); at three seeding rates (150, 300, and 450 thousand viable seeds ha-1) in two cultivars (BMX Potência RR and BRS 359 RR). In both growing seasons, there was a water deficit, and climatic conditions that would restrict soybean growth and development. The narrow rows, twin rows, and crossed rows did not favor yield performance compared to traditional spacing in either cultivar. The tested cultivars showed high phenotypic plasticity, allowing large changes in row spacing and seeding rate without major changes in the yield. The narrow rows, when associated with a high seeding rate, favored plant mortality. Grains per pod and harvest index were not influenced by the plant spatial arrangement.

Secondary crop cultivation is very important for producers of corn and beans crops worldwide, and can reach high levels of productivity. The study aimed to evaluate water use efficiency and grain yield response of corn and bean species cultivated in a secondary crop system, when subjected to different water levels. Two experiments were carried out, one for the corn cultivar DKB 240 and another for the bean cultivar IPR Gralha; the study was developed in an experimental area classified as Oxisol typical, both experimental designs consisted of a randomized single factor block design with five water levels (0, 50, 75, 100 and 125% of reference evapotranspiration; Eto) with three replications. The following variables were analyzed: number of rows per ear, number of grain per row, thousand grain mass and grain yield for corn; number of pods per plant, number of seeds per pod, thousand grains mass and grain yield for beans. Water use efficiency was calculated as the relationship between grain yield and the applied water level. The corn and bean crops had the highest water use efficiency in the levels of 100% and 125% of reference evapotranspiration, respectively. These levels showed the highest yield of crops. Both corn and beans can be recommended for planting in the second crop system as they present a high yield potential under favorable water conditions; in order to meet water demands, they require a total of 413.53 mm for corn and 447.12 mm for the bean cultivar distributed throughout the crop cycle.

“…An uneven spatial and temporal distribution of precipitation makes wheat vulnerable to water deficits during growing development (DENG et al, 2006;ZHOU et al, 2015). The Tai'an region receives precipitation that reaches a maximum level of 200 mm in the growing season of winter wheat.…”

Photosynthetic production of wheat under precision planting patterns in northern china

ABSTRACT:Winter wheat (Triticum aestivum) is cultivated across a wide region; however, water is scarce during the growing season of wheat in the Northern Plain of China. Therefore, winter wheat should be irrigated to maintain a stable and high grain yield. The aim of this field study was to develop a water-conserving precision planting pattern for winter wheat that is grown in the Northern China Plain with the purpose of exploring the benefits in maintaining water and effects on wheat productivity. To accomplish this, several production variables and photosynthetic indexes were measured, including the number of stems, the leaf area index (LAI), photosynthetically available radiation (PAR), net photosynthetic rate, and grain yield. The study was carried out during the 2011-2012 and 2012-2013 winter wheat growing seasons. The experiment included a double-row planting pattern (DRPP) and a single-row planting pattern (SRPP), both of which were either irrigated or rainfed. The area of each plot was 9 m 2 , and the experimental design was a randomized blocks design with three replicates. All results were analyzed with an ANOVA, the F test, and the LSD (p ≤ 0.05) for means comparison. PAR capture ratios in the DRPP were higher than those in the SRPP at 50-120 cm above the ground. The photosynthetic traits of flag leaves under irrigated conditions were not significantly influenced by the respective planting pattern. However, at a growth stage of 80 under the rainfed conditions, the mean photosynthetic rate within flag leaves in the DRPP was higher than that in the SRPP. Furthermore, the DRPP under rainfed conditions was more likely to increase the apparent quantum yield (AQY) of flag leaves than the yield obtained under irrigation. These results suggest that DRPP optimizes the canopy PAR distribution in winter wheat and contributes to the maintenance of a higher photosynthetic capacity in the flag leaves under water stress (the rainfed condition). This relationship may be applied in demonstration trials to encourage winter wheat farmers to incorporate the use of DRPP in the drought-prone areas, which are subjected to insufficient precipitation during the growing stage of wheat in Northern China.
