Background and Objective: Soil fertility depletion and soil acidity are critical problems for maize (Zea mays L.) production in western Ethiopia. Because of this, a field experiment was conducted on acidic Nitisols of the Assosa area to investigate the response of maize to different blended fertilizer rates and types. Materials and Methods: The treatments consists of control, three rates of N and P (92/46 , 115/57 and 138/69 N/P 2 O 5 kg haG 1 ) and two blended fertilizers with three rates (100 kg NPSB+73.9 kg N haG 1 , 150 kg NPSB+110.8 kg N haG 1 , 200 kg NPSB+147.8 kg N haG 1 , 100 kg NPSZnB+75.1 kg N haG 1 , 150 kg NPSZnB+112.6 kg N haG 1 ) and 200 kg NPSZnB+150.2 kg N haG 1 . The experiment was laid out as a Randomized Complete Block Design with three replications. Results: The results revealed that fertilizer types and rates significantly (p<0.01) affected grain yield, stover yield and harvest index. However, there was no significant difference between the two blended fertilizer types (NPSB and NPSZnB). The highest grain yield (7056.2 kg haG 1 ) was recorded with 200 kg NPSZnB+150.2 kg N haG 1 application. Blended fertilizers had improved nutrient concentration and uptake of maize. Application of 150 kg NPSB+110.8 kg N haG 1 recorded the highest marginal rate of return and net benefit. Conclusion: The study demonstrates high improvement in grain and stover yield and nutrient uptake of maize in response to blended fertilizers implying that N, P, S, Zn and B are deficient in Assosa soils, hence external application of these nutrients are vital as a blend for sustainable maize production.

“…The highest harvest index (49.43%) obtained in CF + T 6 (USG, 7 DAT) whereas the lowest value (45.74%) recorded in CF + T 1 (Control) (Table 5). When the application of USG was compared with PU, a non-significant interaction effect on the harvest index of BRRI dhan28 and BRRI dhan29 was found by Bhuiyan et al (2016) and the grain harvest index ranged from 0.40 to 0.52 in BRRI dhan28 and 0.42 to 0.54 in BRRI dhan29. Similarly, Mboyerwa et al (2021) revealed that the harvest index was significantly affected by N levels, which ranged from 0.45 to 0.53, but irrigation methods had little influence (p > 0.05).…”

In rice cultivation, water and nitrogen saving strategies are becoming more crucial in order to identify efficient and useful crop production and management approaches. A study was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh to examine the combined effects of irrigation method and nitrogen fertilizer on yield contributing traits and yield of rice cv. BRRI dhan29. The experiment was set up in a split-plot based on a randomized complete block design with 3 replications and 14 treatment combinations. Two irrigation methods such as continuous flooding (CF) and alternate wetting and drying (AWD) were the main factor while nitrogen fertilizers including prilled urea (PU) and urea super granule (USG) were the sub-factor. The treatment T 6 (USG at 7 DAT) generated the highest plant height (cm), no. of effective tillers hill -1 , panicle length (cm), no. of grains panicle -1 , grain yield and biological yield during AWD condition. In terms of grain yield, the treatment combinations AWD + T 6 and CF + T 7 were statistically equal. In comparison to control, all AWD + USG and CF + PU treatment combinations increased straw yield and harvest index. Under both AWD and CF conditions, USG increased more grain and straw yields compared to PU. So, farmers may be advised to apply USG (216 kg ha -1 ) at 7 DAT under AWD conditions in order to improve rice yield and ensure food security.
