| Abstract | ||||
| Two field experiments were carried out during 2022 and 2023 seasons to study the impact of humic acid, bio-fertilizer and nitrogen fertilizer rates on grain sorghum hybrid Shandaweel-1 productivity. The randomized complete block design using a split-split plot arrangement with three replicates was employed, where nitrogen fertilizer rates (60, 80 and 100 kg N/fed.) were assigned in the main plots, while the humic acid rates (0, 15 and 30 kg/fed.) were allocated in sub-plots and bio-fertilizer (Microbein, Nitrobein and Cerealin) was fixed in sub-sub-plots The grain was planted on 26th and 21st June in the first and second seasons, respectively. The plot area was 12 m2 (4 m long and 3 m width). The results declared that the 100 kg N/fed. × 30 kg HA/fed. interaction treatment gave the tallest plants and the heaviest 1000 grain in the 2nd season, as well as 60 kg N/fed. × without humic acid interaction treatment gave the highest mean values for grains weight/panicle and grain yield/fed. in both seasons. In general, the 80 kg N/fed. xMicrobein interaction treatment recorded the maximum grains weight/panicle and grain yield/fed, 100 kg N/fed. × Microbein interaction treatment recorded the heaviest 1000 grain in both seasons. The 15 kg HA/fed. × Microbein interaction treatment gave the tallest plants season and maximum grain yield/fed. in 1st and 2nd season, respectively. Moreover, without humic acid × Microbein interaction treatment gave the maximum mean values for 1000 grain weight in both seasons, grain weight/panicle and grain yield/fed. in the 1st season. | ||||
