“…This result is in agreement with [16] who reported that plant height of sorghum was increase with increasing rates of NP from 0/0 to 69/46 kg ha -1 . This study is in agreement with [17] who reported that application of NP fertilizer at rate 49/46 kgha -1 significantly increases the plant height of sorghum, and height of sorghum was 18.21 cm greater than control treatment at rate 69 kg N and 46 P 2 O 5 ha -1 fertilizer. It can be concluded the increased rates of N, and P increased the plant growth and biomass, and also the increased amounts of N-P increases the production of sorghum crop [18].…”

“…The maximum mean total biomass yield recorded from 69/23 NP over the control might be due to more nutrients gained from both NP combined fertilizers. The result was in line with [17] who reported that application of NP fertilizer at rate 69/46 kg ha -1 increases the grain yield of sorghum significantly. In the same way, study conducted by [19] observed that NP fertilizer application at rate 92/30 kgha -1 increases the total biomass yield of sorghum by 68.21% advantage over control treatment.…”

“…Also, grain yield was significant and positive correlation growth parameters, yield and yield components of sorghum (Table 2). Similar result was observed in [17] that there is significant increase in grain yield of sorghum when supplied with higher rates of NP fertilizer. This result is in agreement with [19] who reported that application of 92/30 kg ha -1 NP fertilizer rate increased the grain yield of sorghum.…”

“…This indicates that presence of greater stover yield of sorghum might be due to the fact that crops supplied with adequate nutrients have more vegetative growth, longer linear growth rate and more dry matter accumulation which directly related to an increment in stover yield. This result is supported by [17] who reported that application of nitrogen with phosphorus increase on plant height, grain yield and biomass yield of sorghum. The increase in stover yield with higher N levels might be due to the increase in grain and total dry biomass of maize with higher N rates [14].…”

Soil fertility is among the most important constraints that threaten sorghum production in Jimma Zone in Oromia Region. Therefore, a field experiment was carried out at Kersa woreda for four consecutive cropping seasons from 2013/14 to 2016/17 to evaluate the response of various levels of nitrogen (N) and phosphorus (P) fertilizer using sorghum. The treatments consisted of factorial combinations of four rates each of N (0, 23, 46 and 69 kg N ha −1 ) and P (0, 11.5, 23 and 34.5 kg P 2 O 5 ha −1 ) laid down in a randomized complete block design (RCBD) with three replications. For data analysis, correlation coefficient and ANOVA were used. The result showed that the yield and yield components of the sorghum crop were highly significant response to impacts of inorganic N-P fertilizer nutrients. Parameters, such as, plant height, head weight, grain yield, biomass yield and stover yield, were statistically significantly different by nitrogen and phosphorus different fertilizer rates. Also, these parameters were significant and positive correlation to each other. This result revealed that the highest (4.14 t/ha) grain yield was obtained from 69 kgh -1 N and 23 kgha -1 P 2 O 5 inorganic fertilizer, whereas the lowest (1.37 t/ha) grain yield was recorded from control treatment. Compared to the control treatment, the highest rate of N/P (69/23 kg ha -1 ) increased sorghum grain yield by about 202.2%. It is concluded that nitrogen and phosphorus at the rate of 69 kgh -1 N and 23 kgha -1 P 2 O 5 has the best performance in obtaining maximum grain yield of sorghum crop. Therefore, N-P at the rate of 69 kgh -1 N and 23 kgha -1 P 2 O 5 is highly recommended for optimum grain yield of sorghum crop in the study area.

“…In line with these results, Gebrekorkos et al [39] described that the application of fertilizer increases plant height of sorghum in Raya valley Ethiopia. In line with this result, Sebnie and Mengesha, [40] also stated that nitrogen and phosphorus fertilizers signifcantly afect the plant height of sorghum in the Wag-Lasta area of Ethiopia. In addition, Gebremariam and Assefa [41] also informed that the lowest and the maximum plant height of sorghum was attained from plots without nitrogen application and from 150 kg•ha −1 nitrogen, respectively.…”

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