More than 3 billion people live in agricultural areas with high to very high levels of water shortages and scarcity, and freshwater resources per person have declined by more than 20 percent over the past two decades, FAO's SOFA 2020 report says.

With the lingering after-effects of a crippling drought, and the National Water and Sanitation Master Plan likely to kick in next year, it was time that all stakeholders in South African agriculture started taking responsibility for their role in protecting the country’s scarce freshwater resources.

This was according to water conservation and water law experts, who were speaking during Nedbank’s webinar, ‘The future of water in South Africa’s agricultural sector’, held on Tuesday, 3 November.

Shelly Fuller, programme manager of sustainable fruit and wine projects at Worldwide Fund for Nature South Africa, said agriculture used the largest proportion of South Africa’s surface and groundwater resources.

While the sector made vital contributions to the country’s economy and society, it had to proactively implement meaningful actions to conserve water for its own long-term sustainability, and for the future needs of the rest of the country.

Root morphology and its components’ behavior could show a considerable response under multiple water application points per plant to help the ultimate effect of fruit yield and fruit quality. In this study, a comparison of a single emitter per plant was made with two, three, and four emitters per plant under drip irrigation and two irrigation levels (full irrigation 100% and deficit irrigation 75% of crop evapotranspiration) to investigate their effects on physiological parameters, root, yield, and their associated components for potted cherry tomato under greenhouse conditions in Jiangsu-China. The experimental results showed that the plants cultivated in the spring-summer planting season showed significantly higher results than the fall-winter planting season due to low temperatures in the fall-winter planting season. However, the response root length, root average diameter, root dry mass, leaf area index, photosynthetic rate, transpiration rate, fruit unit fresh weight, the number of fruits, and pH were increased by multiple emitters per plant over a single emitter per plant, but total soluble solids decreased. Besides, a decreasing trend was observed by deficit irrigation for both planting seasons, and vice versa for the case for tomato total soluble solids.

Alleviation of Salt Stress by Plant Growth-Promoting Bacteria in Hydroponic Leaf Lettuce

Mediterranean areas with intensive agriculture are characterized by high salinity of groundwater. The use of this water in hydroponic cultivations can lead to nutrient solutions with an electrical conductivity that overcomes the tolerance threshold of many vegetable species. Plant growth-promoting rhizobacteria (PGPR) were shown to minimize salt stress on several vegetable crops but the studies on the application of PGPR on leafy vegetables grown in hydroponics are rather limited and have not been used under salt stress conditions. This study aimed to evaluate the use of plant growth-promoting bacteria to increase the salt tolerance of leaf lettuce grown in autumn and spring in a floating system, by adding a bacterial biostimulant (1.5 g L−1 of TNC BactorrS13 a commercial biostimulant containing 1.3 × 108 CFU g−1 of Bacillus spp.) to mineral nutrient solutions (MNS) with two salinity levels (0 and 20 mM NaCl). Leaf lettuce plants showed a significant reduction of growth and yield under salt stress, determined by the reduction of biomass, leaf number, and leaf area. Plants showed to be more tolerant to salinity in autumn than in spring.

Irrigation is an important tool that likely has been used in agriculture for about as long as humans have been cultivating plants, but just how much water is enough?

Researchers from the Clemson University Edisto Research and Education Center (REC) are working on projects they believe will help South Carolina farmers conserve water and save money.

One project, funded by the state legislature, is developing software that can help take the guessing out of irrigation system efficiency. It is a GPS-based center-pivot auditing software used to calculate water-distribution uniformity in fields.

During Wageningen University’s Autonomous Greenhouse Challenge team AuTomatoes applied the principles of Plant Empowerment in their winning AI strategy. Thus, the team’s strategy was focused on the plant and it’s balances, in order to create a balanced and empowered crop. So how did they do this? This article explains all about the water balance and how team AuTomatoes kept it in balance at all times.

The water balance is the balance between the input to and output of water from the plants. Output of water is mainly caused by evaporation. Only a little portion of the total water uptake is stored in the plant and the fruits. Plants need to evaporate and thus take up water from the root zone for three reasons: the uptake of nutrients, for growth, and for cooling. In order to keep the water balance in balance, the uptake of water from the root zone must equal at least the evaporation rate. Thus, to ensure sufficient water availability, irrigation needs to be aligned with the plant’s evaporation rate.

Various algorithms were developed to support the tomato crop’s water balance in order to optimize the tomato yields. For example, some of these algorithms made use of a plant temperature sensor and pyrgeo sensor to calculate the net radiation on plant level. Based on this calculation the algorithms decided on the optimal screen position for the crop to receive the right amount of radiation to keep a steady evaporation rate.
