Special Issue Information

Dear Colleagues,

In agricultural production, water and fertilizer are important factors affecting crop growth and are the key to obtaining high and stable yields. Unreasonable soil water and fertilizer application leads to low crop yield and low water and fertilizer use efficiency and will cause serious environmental pollution. Therefore, efficient soil water and fertilizer management is an urgent need for the sustainable development of global agriculture.

Recent studies have revealed that the regulation of soil water and fertilizers affect crop growth, development, yield and composition, and have developed models for simulating crop response to soil water and fertilizers at different growing stages. AT the same time, the mechanisms behind and the simulation of crop physiological responses to different soil water and fertilizer challenge our current understanding. This Special Issue aims to illuminate the complexity of soil water and fertilizer in relation to crop phenotype and physiological and biochemical processes under different scenarios.

This Special Issue welcomes original research articles and reviews. Research areas may include (but are not limited to) the following:

  • Irrigation water and fertilizer optimization methods and technologies;
  • Crop-water relations, crop yields, and water productivity;
  • Crop physiological response to soil moisture and fertilizer application;
  • Fertilizer absorption and utilization efficiency;
  • Environmental impacts of irrigation and fertilizer management;
  • Soil water and fertilizer interact with roots;
  • Response of soil moisture to precipitation;
  • Rainwater harvesting and crop water management in rainfed areas.

We look forward to receiving your contributions.

To study the optimal plant row configuration of the multiple cropping of soybeans that are suitable for planting in southern Xinjiang, a field experiment using soybean variety SN35 was carried out employing different plant row designs. Three row spacing treatments of 15 cm (H1), 30 cm (H2), and 45 cm (H3) and three density treatments of 52.56 million (M1), 55 million (M2), and 60 million (M3) plants per hectare were set up in this experiment to explore the effects of different plant row spacing configurations on agronomic traits, photosynthetic characteristics, dry matter accumulation, and the soybean yield of the multiple cropping of soybeans. The results showed that the soybeans’ plant height, diameter, main stem node number, leaf shape index, leaf area index (LAI), leaf area duration (LAD), and pod dry matter distribution ratio increased gradually with the growth process. In contrast, the stem dry matter distribution ratio decreased gradually, and the leaf dry matter distribution ratio first increased and then decreased. The plant height of the soybeans treated with H2M3 was the highest, reaching 67.38 cm. The number of primary stem nodes of the soybeans treated with H1M3 was the highest, reaching 12.7 nodes. The stem diameter of the soybeans treated with H1M1 was the highest, reaching 0.64 cm. The leaf shape index of the soybeans treated with H3M1 was the highest, reaching 2.72. Intercellular CO2 concentration closely affects the final yield; the correlation coefficients with the pod number per plant, seed number per plant, and yield reached 0.75, 0.78, and 0.87, respectively. The theoretical maximum hundred-grain weights under the H1M1 and H2M1 treatments were higher, reaching 20.33 g and 17.98 g, respectively. The H3M3 treatment had the most significant one-hundred-grain weight, reaching 21.27 g. The soybean yield of each density treatment was M3 > M1 > M2. With the increase in row spacing, the average pod number per plant, grain number per plant, grain weight per plant, and yield of soybeans decreased gradually, and the hundred-grain weight increased gradually. The yield of the density treatment with 60 million plants per hectare under 15 cm row spacing was the highest, reaching 6155.8 kg·hm−2, followed by the density treatment with 60 million plants per hectare under 30 cm row spacing, reaching 5850.6 kg·hm−2.

In the contemporary era, the excessive use of chemical fertilizers in areas where strawberries are intensively cultivated disrupts the balance of nature and reduces economic efficiency. Therefore, using organic and biofertilizers in sustainable agriculture can solve these problems. The effect of organic fertilizer and other treatments on the yield, quality, and plant growth of the Monterey strawberry variety was investigated. Solid farm manure and a liquid organic fertilizer of vegetable origin were used as basic fertilizers, while five different commercial fertilizers containing bacteria and mycorrhiza were used as complementary fertilizers. In addition, this study examined plant growth parameters, including root length, stem diameter, leaf area, yield per plant, fruit weight, pH in the fruit, SSC, acid, SSC-to-acid ratio, and plant nutrient content. The Biofarm+Botanica+Fontera microzone bacterial fertilizer (Azosprillium brasilense, Azotobacter vinelandii, Rhizobium trifollii, Pseudomonas fluorescens, Bacillus subtilis, Bacillus licheniformis, Azotobacter chroococcum, Bacillus amyloliquefaciens, and Bacillus mucilaginosus) treatment provided the best results; namely, it produced the highest total yield (250.17 g plant−1), largest fruits (18.13 g), highest SSC-to-acid ratio (18.05), and best nitrogen, phosphorus, potassium, calcium, and magnesium contents in the leaves. Similarly, the same treatment produced the longest root, thickest stem, and maximum leaf area. As a result of this study, it is recommended to use biofertilizers together with organic fertilizers to ensure high-quality fruit production. Full article
