Identification of Yield-Limiting Nutrients for Sorghum (Sorghum bicolor (L.) Moench) Yield, Nutrient Uptake and Use Efficiency on Vertisols of Raya Kobo District, Northeastern Ethiopia

Agricultural productivity was negatively impacted by low soil fertility and uneven fertilizer application during crop cultivation in Ethiopia. Because of this, important crops frequently respond to applications significantly below their achievable potential yields. This study carried out determine the most sorghum yield-limiting nutrients Raya Kobo area Amhara Region 2020/21 season. Sorghum variety Girana-One used as test crop. Control, NPS, PSBZn, NPBZn, NSBZn, NPSB, NPSZn, NPSBZn, recommended NP, NPSKBZn were treatments. Three replications experiment a randomized complete block design. Before treatment application, composite sample collected at depth 0–20 cm soil’s physicochemical properties. To evaluate N P uptakes, samples stalk grain collected. SAS software analyze data. Results showed that, NPKSZnB produced considerably greater yield (4620 kg·ha−1), whereas control omitted plots lowest yields (2759 kg·ha−1) 2805 kg·ha−1, respectively. Nitrogen missing statistically significant drop compared other plots, there no difference between prescribed NP potassium, sulfur, boron, or zinc plots. The treated with had highest agronomic efficiency for (19.7 kg kg−1·N) (10.6 kg−1 P2O5). Therefore, research development should therefore concentrate on nitrogen achieve best location. Phosphorus might also be keep level within ideal range.
