“…Similarly, increased SW (Figure ) under T 2 in SM and MS R might be due to higher LAI (Figure ) and photosynthetic rate (Table ) at PM (Borrás et al, ), whereas decreased LAI, photosynthetic capacity and BA of maize plants in T 3 and T 4 reduced the seed number and SW (Tollenaar & Daynard, ; Wang, Niu, Wang, & Zhang, ). However, the excision of six leaves from the top of the maize canopy increased the HI, and to this may be attributed the reduced vegetative plant dry matter as compared to the reproductive dry matter (Wasaya et al, ).…”

Without developing new agronomic practices, present rates of improvement in seed yields of cereal crops globally are insufficient to fulfil the estimated increasing food demand for 2050 and beyond. Intercropping is one of the agricultural practices that can lead to greater crop yields. However, there exists leaf redundancy for maize in intercropping systems, and the top canopy leaves shade more competent leaves at middle strata of maize plants. Therefore, this work aimed to elucidate the effect of leaf excision treatments in maize to understand the optimum leaf area of maize plants under a maize-soybean relay-intercropping system (MS R ) and a sole cropping system (SM). The effects of four-leaf excision treatments (T 1 , 0; T 2 , 2; T 3 , 4; T 4 , 6 leaves excised from the top of maize plants until 7 days after silking) on light interception, leaf area index (LAI), photosynthetic characteristics, total biomass accumulation at blistering stage (BS), dough stage (DS) and physiological maturity (PM), and seed yield of maize were investigated through field experiments for 2 years under MS R and SM. Results showed that, under MS R and SM, as compared to control (T 1 ), optimum excision of leaves (T 2 ) from the top of maize plants significantly improved the light interception (by 25, 18 and 16% at BS, DS and PM, respectively) to lower strata leaves and accelerated the biomass partitioning to maize seeds (by 13 and 12% at DS and PM, respectively). Importantly, plants under T 2 exhibited higher green leaf area than control, that is, excision the top two leaves led to an increase in LAI at PM by 10%, suggesting that leaf senescence under T 2 was delayed which enhanced the photosynthetic rate at PM by 7% in 2017 and 6% in 2018. Relative to T 1 , maize under T 2 produced 19 and 13% higher maize yield under MS R and SM, respectively, and relaycropped maize had 90% of SM seed yield. These results suggest that by manipulating the canopy structure of maize plants we can enhance the biomass accumulation and seed yield of maize crops under MS R and SM.

Oilseeds yield response to sulphur (S) has been well investigated but the dynamics of total biomass accumulation (TBA) and partitioning by sesame plants in response to S are not well understood. This study was initiated to investigate the effects of S on sesame, in which four sesame varieties V1, SG-27; V2, SG-30; V3, SG-36; V4, SG-51 and four S treatments T1, 20; T2, 30; T3, 40; T4, 50 kg ha−1 were used. Results revealed that the leaf area index and photosynthetic rate of sesame varieties were significantly higher under T3 with V3. Similarly, S fertilization considerably increased the TBA and maximum TBA was reached at late-flowering with V3 in T3. Relative to T1, plants in T3 had 33 and 23% higher capsule and seed biomass, respectively. Furthermore, total S accumulation and distribution in different plant organs changed with growth stage, at pre-flowering and mid-flowering stage maximum S was found in the stem, whereas at late-flowering and full-maturity stage highest S was recorded in reproductive parts. These results implied that S fertilizers should be applied to agricultural fields to improve oilseed production and by selecting the appropriate and area-specific genotype we can increase sesame seed yield under rainfed conditions.

“…For example, crop intercropping makes full use of light energy and increases yield [4]. The improvement of fertilization technology can increase roots' nutrient absorption and leaves' net CO 2 assimilation [5]. Microelement and CO 2 fertilizer can regulate mesophyll cell activity and photosynthate accumulation [6][7][8][9].…”

An experiment was conducted in China to develop guidelines for the mulching drip irrigation of commercial muskmelon crops. Three sets of factors were laid out in rows to give a three × three factorial design. First, plastic covers were placed over the entire growing area (rows and inter-rows, or full), over the rows (half), or no plastic applied (none). Second, there was one irrigation pipe per row (T1), three pipes for four rows (T3/4), or one pipe for two rows (T1/2). Finally, the plants were irrigated when the soil water content fell to 60%, 70%, or 80% of field water capacity (FC). Information was collected on net CO2 assimilation (Pn), plant growth, and yield. Overall, maximum Pn occurred with half plastic covering, one irrigation pipe for two rows, and irrigation at 80% FC. Plant fresh weight was higher with half plastic covering, one irrigation pipe per row, and irrigation at 70% or 80% FC. Yield was higher with half plastic covering, and irrigation at 70% or 80% FC. There were only small differences in the yield across numbers of irrigation pipes. These results suggest that overall productivity was better with plastic covers over the rows and irrigation at 70% or 80% FC. Differences in productivity with different numbers of irrigation lines per row were small.
