“…Irrigation promotes the branching and canopy width [ 32 , 33 ], leaf growth and development [ 34 ], and photosynthetic capability [ 35 , 36 ] of plants. This results in an increase in the aboveground biomass, which is consistent with the finding that irrigation can increase the biomass of Elymus nutans [ 37 ].…”

Planting halophytes such as Suaeda salsa (L.) Pall. under drip irrigation is a viable solution for the remediation of saline soils. We conducted this study to investigate the effects of different irrigation volumes and planting densities on the growth and salt uptake of Suaeda salsa under drip irrigation. The plant was cultivated in a field using drip irrigation at various irrigation volumes (3000 m·hm−2 (W1), 3750 m·hm−2 (W2), and 4500 m·hm−2 (W3)) and planting densities (30 plants·m−2 (D1), 40 plants·m−2 (D2), 50 plants·m−2 (D3), and 60 plants·m−2 (D4)) to examine the effects on growth and salt uptake. The study revealed that the amount of irrigation, planting density, and interaction between the two significantly affected the growth characteristics of Suaeda salsa. The plant height, stem diameter, and canopy width increased simultaneously with an increase in the irrigation volume. However, with an increasing planting density and the same irrigation volume, the plant height first increased and then decreased, while the stem diameter and canopy width decreased simultaneously. The biomass of D1 was the highest with the W1 irrigation, while that of D2 and D3 were highest with the W2 and W3 irrigations. The amount of irrigation, planting density, and their interaction significantly affected the ability of Suaeda salsa to absorb salt. The salt uptake increased initially and then decreased with an increasing irrigation volume. At the same planting density, the salt uptake of Suaeda salsa with the W2 treatment was 5.67~23.76% and 6.40~27.10% higher than that with W1 and W3, respectively. Using the multiobjective spatial optimization method, the scientific and reasonable irrigation volume for planting Suaeda salsa in arid areas was determined to be 3276.78~3561.32 m3·hm−2, and the corresponding planting density was 34.29~43.27 plants·m−2. These data can be a theoretical basis for planting Suaeda salsa under drip irrigation to improve saline–alkali soils.

“…Leaf length was calculated by measuring the length of the largest fully expanded leaf using a carpenter's tape and the width of the largest leaf was measured by taking its broadest breath as a reading. In accordance with the methodology outlined by Onasanya et al, 2009 andMokhtarpour et al, 2010, the leaf area was estimated by multiplying leaf length by leaf width x a constant (0.75) Number of leaves per plant was counted visually. The maize cobs were manually shelled, and the number of grains per cob, weight of 100 grains per cob, weight of 100 grains per plant, grain yield per plot, and the yield per hectare (kg/ha) were all recorded.…”

The growth and yield of three maize cultivars were examined in relation to the impact of Municipal Solid Wastes (MSW) enriched soil. According to the results, plants grown on soil treated with MSW and inorganic fertilizer (NPK) produced significantly (P≤0.05) taller plants, larger leaves and higher number of leaves than plants grown on the control soil. On the other hand, plants grown on soils fertilized with MSW 1 showed significantly (P≤0.05) greater values of these indicators. The study also demonstrated that maize cultivar TZE yellow, EVDT 99 and Comp-1-synthetic showed no significant variation at the later growth stage but TZE yellow significantly (P≤0.05) had taller plants, larger leaves, and higher number of leaves at the early stage of crop growth. Comp-1-synthetic produced more grain and more grains per cob which was statistically at par with TZE yellow but differ significantly (P≤0.05) from EVDT 99. Crops grown on MSW and NPK treated soils had significantly (P≤0.05) higher grain yields and more grains per cob than those grown on the control soil. However, compared to NPK treated soils, MSW treated soils significantly (P≤0.05) produced better grain yield and number of grains per cob. The maize cultivars' differences in crude protein content were significant at P≤0.05. The crude protein content of TZE yellow was significantly (P≤0.05) higher than that of EVDT 99 and Comp-1-synthetic. Additionally, plants cultivated on MSW 1 treated soil had considerably higher crude protein content than plants grown on other soil types. Therefore, if municipal solid wastes are sorted and handled, MSW enriched soils could be employed to boost maize production.
