IntroductionSorghum is emerging as a viable crop option to increase food production under changing climate due to its resilience to drought and marginal soils. Appropriate planting date, crop cultivars, type of tillage and rotations, under contrasting climatic conditions, could make significant contribution on the effective management of sorghum under changing climatic conditions. A short-term study was carried out to investigate the effects of planting date, crop cultivar, tillage type and rotations on the growth and primary nutrient uptake of sorghum in contrasting climatic regions.MethodsThe study was conducted in Free State - (FS) and KwaZulu Natal (KZN) Provinces of South Africa over two seasons (2020/21 and 2021/22). The two cultivars (Pan8816 and Macia) were sown in December (PD1) and in January (PD2) under conventional tillage (CT) and no-till (NT) and with two rotations (Sorghum-Cowpea-Sorghum and Sorghum-Sorghum-Sorghum) resulting in 2×2×2×2 factorial experiment.Results and discussionIn KZN, in both the first (2020/21) and second (2021/22) seasons, the effects of all the factors, except cultivar in the second season, were not significant on yield, and uptake of nitrogen (N), phosphorus (P) and potassium (K). In the second season, Pan8816 (4.40 t/ha) produced 3.3 times higher yield than Macia (1.32 t/ha), and took up higher N, K and P. In FS, the early planted sorghum (1.15 t/ha for season one; 3.39 t/ha for season two) had significantly higher yield than late planted sorghum (0.434 and 0.91 t/ha for seasons one and two, respectively). Furthermore, the early-planted crops took up higher N, K and P than when planted late, while Pan8816 took up 1.74 times more P than Macia. Plants grown under CT (2.61 t/ha) produced significantly higher yield than under NT (1.70 t/ha), with plants under CT taking up significantly more K than those grown on NT. These findings suggest that in the drier FS, early planting under conventional tillage, while in the wetter KZN, selecting the appropriate cultivar (PAN8816), are essential for sorghum grain yield, at least in the short-term.

“…In comparison with the other treatments, the higher yield loss was recorded in the unfertilized plots and omitted N plots. These results were expected since that they could be the result of poor nutrient supply in the soil, which did not satisfy the N demand of the sorghum crop [7]. Omission of P and K resulted in 12.4 and 17.5% reduction in grain yield, respectively in wheat [8].…”

A field experiment was conducted at Agricultural Research Station, Tandur, Professor Jayashankar Telangana State Agricultural University during 2020-21 and 2021-22 to study the impact of nutrient omission on productivity and profitability of Rabi sorghum. The experiment was laid out in randomized block design with 3 replications. Pooled data results indicated that among the nutrient omissions treatments, significantly higher plant height (211.7 cm), days to 50% flowering (75 days), panicle length (17.9 cm), number of grains panicle-1 (946), grain yield (1234 kg ha-1), fodder yield (5788 kg ha-1), harvest index (18.17), net returns of Rs. 44,790 ha-1 and BC ratio of 2.68 were recorded in no omission treatments and it was on par with K omission followed by N omission and lowest with NPK omission (control) treatments. When compared to the no omission (NPK) treatment, the rabi sorghum grain yields were decreased by 2% with the K omission, 10% with N omission, 15% with P omission, 22% with PK omission, 23% with NK omission, 29% with NP omission and 39% with NPK omission.

The Ethiopian government has recently imported and distributed multi-nutrient fertilizers for farmers' use without sufficient research finding. Selecting the appropriate fertilizers based on the actual limiting plant nutrients is crucial for providing timely policy direction to import only fertilizers that could limit crop yield. A field study was carried out to identify the yield-limiting plant nutrients for wheat under irrigation at two farmer’s fields in the Woleh irrigation scheme of the Amhara region of Ethiopia in the 2022 irrigation season. A total of nine treatments, including control, NPSKZnB (all), NPSKZn (all-B), NPSKB (all-Zn), NPKZnB (all-S), NPSZnB (all-K), NKSZnB (all-P), PKSZnB (all-N), and RNP (all-KSZnB), were arranged in a randomized complete block design (RCRD) with three replications. The Kekeba wheat variety was used as a test crop. The collected grain and biomass yield data were analized by using SAS software following the procedure. The analysis of result showed that the application of fertilizer had a significant effect on wheat grain yield. The highest grain yield (4443.5 kg ha-1) was obtained from NPKZnB (All-S). While the lowest grain yield was obtained from the control and nitrogen omitted treatment. There was no significant difference between and among the treatments except Control, All-N, and All-P. The grain yield was reduced by 3181.6 kg ha-1 when N was omitted and 1817.8 kg ha-1 when P was omitted over All-S (NPKZnB). This showed that nitrogen and phosphorous are yield-limiting plant nutrients for wheat under irrigation in the study area. Therefore, the government should give emphasis to nitrogen- and phosphorous-containing fertilizers to increase wheat yield.
