“…On the other hand the 2013 season had close to normal growing season precipitation from June to August (119.0 mm vs 134.3 mm in long-term), but the cooler temperatures would contribute to reduced evapotranspiration, especially during July (17.1 • C vs 18.8 • C in long-term). Compared to wider row spacing, these favorable conditions would be more beneficial to plant growth for narrower row spacing, resulting in greater plant density and radiation interception hence higher yield for the narrower row spacing (Mattera et al, 2013). This suggests that a row spacing of 30 cm was optimal at Central Butte for yield and doubling row spacing to 60 cm would negatively impact yield under the conditions of this study.…”

“…Few studies have compared light interception and other microclimate characteristics in crops grown in different row-spacing systems, and none have examined cluster planting. Greater light interception has been reported with narrow row spacing in cotton (Gossypium hirsutum L.) (Heitholt et al, 1992) and other crops such as lucerne (Medicago sativa OPEN ACCESS L.) (Mattera et al, 2013), maize (Zea mays L.) (Liu & Song, 2012) and potato (Solanum tuberosum L.) (Tarkalson et al, 2012). Gwathmey and Clement (2010) found that early canopy development (leaf area) and, consequently, early light interception was higher in ultra-narrow rows than with conventional spacing.…”

The causal factors for this improved growth induced by cluster planting pattern, the light interception, canopy microclimate and photosynthetic rate of cotton were investigated in an arid region of China. The results indicated that the leaf area index and light interception were higher in cluster planting, and significantly different from those in traditional planting during the middle and late growth stages. Cotton canopy humidity at different growth stages was increased but canopy temperatures were reduced by cluster planting. In the later growth stage of cluster planting, the leaf chlorophyll content was higher and the leaf net photosynthetic rate and canopy photosynthetic rate were significantly increased in comparing with traditional planting pattern. We concluded that differences in canopy light interception and photosynthetic rate were the primary factors responsible for increased biomass production and economic yield in cluster planting compared with the traditional planting of cotton.

“…The spike number of DRPP were 22.8% (2011-2012) and 25.5% (2012-2013) higher than those of SRPP, but the 1000-kernel weight were 1.4% (2011-2012) and 9.1% (2012-2013) lower in DRPP than those of SRPP, respectively (Table 2). Meanwhile, under rainfed conditions, the kernel number per spike and 1000-kernel weight of DRPP were higher than that of SRPP in 2011-2012, and the kernel number per spike and 1000-kernel weight were not significantly different between SRPP and DRPP in 2012-2013(p > 0.05). However, in 2011-2012and 2012-2013, the spike numbers of DRPP were 6.9% and 22.8% higher than those of SRPP, and the grain yields were significantly higher (by 11.3% and 11.0%) than that of SRPP, respectively (p ≤ 0.05).…”

“…Meanwhile, cultivation methods have become increasingly more relevant in dealing with drought. Row spacing is an agronomic practice that affects the canopy structure, light interception, radiation use efficiency, and biomass production in some plants (ACRECHE et al, 2009;MATTERA et al, 2013). The main factors that influence plant growth include light, water, nutrients, and weed competition (BRANT et al, 2009).…”

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.
