“…The nitrogen, phosphorus, and potassium rates in AWW significantly increased tomato stem girth. The findings suggest that these organic nutrients jointly improve soil fertility and increase stem girth (Tsige et al, 2022). This result is also similar to the findings of Ojobor and Egbuchua (2020)…”

With the growing necessity to use wastewater for irrigation due to water scarcity, farmers face the challenge of using wastewater containing non-profiled nutrients that may be detrimental to crop productivity. The study investigated the effects of water from abattoirs on tomato plant growth and development. Abattoir wastewater (AWW) was obtained from Surulere and Agege abattoirs in Lagos State. The experimental design implemented a randomized complete design (RCD) with three replications. Tomato plants were grown in experimental pots and treated with different amounts of AWW: Tap water (control), 20, 40, 60, 80, and 100%. Data on plant height, branch and leaf numbers, fruit yield, stem girth, and root length, were collected at two-week intervals for five months. Data was subjected to analysis of variance (ANOVA), and the means were separated using the Tukey HSD test at a threshold of 5% (P<0.05). The study revealed that AWW significantly increased tomato growth characteristics and fruit yield at 100% AWW concentration. Thus, AWW may be an alternative source of organic nutrients for vegetable crop irrigation and could assist farmers with the escalating issues of freshwater scarcity and drought challenges worldwide.

To fundamentally explore the correlation between crop nutritional quality and mineral elements, specific tests and accurate analysis were carried out on all organs and root soil of watermelon (Citrullus lanatus). The results showed that the distribution patterns of nitrogen and phosphorus at watermelon maturity were similar, and the average nitrogen and phosphorus contents were in the orders of leaf and seed > stem, peel, root > pulp > root soil, and peel > seed > root, stem, leaf > root soil > pulp, respectively. From the perspective of element geochemistry, biophile and lithophile elements had the strongest correlation with nitrogen and phosphorus, and watermelon did not antagonize soil nitrogen and phosphorus uptake. The prediction model of nitrogen translocation factor in watermelon organs to total acid was established by partial least squares with R2 = 0.81. Significantly, when the isometric log-ratio of nitrogen to phosphorus in watermelon leaves was 1.97 to 2.19, the watermelon pulp showed better quality with total acid > 0.5%, total sugar > 5% and soluble solids > 10%. Therefore, the characterization of nitrogen and phosphorus in watermelon leaves can serve as a non-destructive analysis to predict watermelon fruit quality.

Yield Gaps of Major Cereal and Grain Legume Crops in Ethiopia: A Review

et al. 2022

In Ethiopia, smallholder farmers are responsible for most food production. Though yield levels in grain crops have improved greatly over the years, they are still much lower than their potential. The source of yield improvements and the causes of those yield gaps are not well understood. To explain the drivers of yield gaps and current sources of yield improvements in four major cereals (teff, maize, wheat, and sorghum) and three grain legumes (faba bean, common bean, and soybean), we accessed the databases of the Global Yield Gap Atlas, the Food and Agriculture Organization of the United Nations, and the Central Statistical Agency of Ethiopia. Refereed journal articles and grey literature were sought in online databases using keywords. The results showed large increases in production of grain crops with little or no increase in areas of production. The yield increases were primarily attributed to genetic gain rather than agronomic improvements. Farmers’ yields remain far lower than those from on-farm trials and on-station trials and the calculated water-limited yield potential. Currently, yields of wheat, maize, sorghum, and common bean in Ethiopia are about 26.8, 19.7, 29.3, and 35.5% of their water-limited yield potentials. Significant portions of the yield gaps stem from low adoption and use of improved varieties, low application of inputs, continual usage of un-optimized crop management practices, and uncontrolled biotic and abiotic stresses. Proper application of fertilizers and use of improved varieties increase yield by 2 to 3 fold and 24–160%, respectively. Cereal-legume intercropping and crop rotation practices increase yield while reducing severity of pests and the need for application of synthetic fertilizers. In contrast, abiotic stresses cause yield reductions of 20–100%. Hence, dissection of the water-limited yield gap in terms of technology, resource, and efficiency yield gaps will allow the prioritization of the most effective intervention areas.
