El-Shaboury Hayamelshaboury123@gmail.com <p>Improving agricultural practices is a very important matter and remains a focal point for individuals engaged in the realm of plant nutrition. So, a field trial during two consecutive seasons of 2021/22 and 2022/23 was carried out under a randomized completed block design to assess the impact of potassium humate (KH) as soil addition as well as garlic extract (GE) and lemongrass extract (LE) as foliar application on the growth performance and productivity of faba bean plants either as individual or combined applications (KH+GE and KH+LE). Plant height (cm), No. of branches plant<sup>-1</sup>, fresh and dry weights (g plant<sup>-1</sup>), chlorophyll a and b as well as carotenoids (mg g<sup>-1</sup>FW), green pod yield of faba bean (ton fed<sup>-1</sup>), No. of pods plant<sup>-1</sup>, 100 seed weight (g), seed and straw yield (ton fed<sup>-1</sup>), seed chemical composition (N,P,K%), seed nutrient uptake (N,P,K, kg fed<sup>-1</sup>), and seed quality (protein and carbohydrate, %) were measured and determined. The results show that the most effective treatment in achieving the highest values was the combined application of potassium humate and garlic extract followed by the combined treatment of potassium humate and lemongrass extract. The treatment involving only potassium humate addition ranked third, followed by garlic extract treatment alone, lemongrass extract treatment alone, and finally, the control treatment (without any additions). The observed synergistic effects suggest the potential for these treatments to be a valuable strategy in faba bean cultivation. Generally, these results provide valuable insights for improving agricultural practices.</p> 2024-01-20T00:00:00+00:00 Copyright (c) 2024 © Copyright I.K. Press.

The experiments consist of five rates 0, 6, 8, 10 and 12 t ha-1 of cow dung were laid out in a Randomized Completed Block Design (RCBD), replicated three times. Okra parameters measured were; plant height, leaf number, pod length, diameter and total pod weight. For plant height and leaf area a non-significant treatment effect was observed for the first 2 weeks respectively whereas, plants provided with 10 and 12 t ha-1 of cow dung significantly (p&lt;0.05) increased plant height and leaf area in the last 4 to 8 weeks respectively. Similarly, the highest application rate of 10 and 12 t ha-1 significantly (p&lt;0.05) increased the pod length, pod diameter and pod weight for the entire period of study as compared to the rest. Control (0 t ha-1) was significantly lower than all the plots that received cow dung in the experiments. Application of cow dung improved soil chemical properties such as pH, N, OM, P, K, Mg and CEC compare with the initial and control treatments. The study concluded that application of poultry manure improved okra production and increased available nutrients and soil restoration.</p> 2024-02-21T00:00:00+00:00 Copyright (c) 2024 © Copyright I.K.

Variety in the Southern Zone of Tigray, Ethiopia 2024-05-09T12:03:50+00:00 Abrhaley Shelema shelemaab@gmail.com Getachew Hruy Berhan Mengesha <p>The primary objective of this study was to assess the impact of nitrogen fertilizer rates on the growth, yield, and yield components of Bombay red onion variety. The study was carried out using a randomized complete block design. The study was carried out at Alamata Agricultural Research Center in Kara Adishabo in 2019, testing various Nitrogen fertilizer rates (0, 23, 46, 69, and 92 kg N/ha) with three replications. Results indicated that the different rates of Nitrogen fertilizer significantly wavered most of the growth, yield and yield components of the onion where the highest leaf number (14.67) was obtained from 92 Kg N/ha while the lowest mean number of leaves per plant (4.33) was recorded at nill Kg N/ha while the highest marketable bulb yield was obtained in treatments that received 92 Kg N/ha (38.30 t/ha) and 69 Kg N/ha (40.01 t/ha) which was not statistically different while the lowest one was obtained in treatments that received nill Kg N/ha (17.93 t/ha) and 23 Kg N/ha (19.42 t/ha). Applying 69 kg of nitrogen per hectare in the study area can result in achieving the highest yield of Bombay red onion variety.</p> 2024-05-09T00:00:00+00:00 Copyright (c) 2024 Author(s).
