A field experiment was conducted in 2014 and 2015 cropping seasons at the Teaching and Research Farm of the Federal University of Technology, Minna to evaluate the effects of different rates of nitrogen (N) and zinc (Zn) on the growth and yield of maize. The treatments included four levels of N: 0, 60, 90 and 120 kg ha-1 and three levels of Zn: 0, 2.5 and 5 kg ha-1. The experimental design was a 4 ? 3 factorial design fitted in a randomized complete block design with three replications. The soil was relatively low in initial N content and relatively high in soil extractable Zn of 2.30 mg kg-1. The main effect of N on the plant height of maize was significant (p<0.05) only at 8 weeks after sowing (WAS) in 2014 and 8 and 12 WAS in 2015. In 2014, the interaction effect of N and Zn on the plant height of maize was only significant (p<0.05) at 8 WAS in both seasons, and application of nitrogen rate of 90 kg N ha-1 with 5 kg Zn ha-1 produced the highest plant height at 8 WAS. The treatments without N produced the lowest grain and stover yields. There was a significant (p<0.05) response to N fertilization on grain yield in both seasons. The main effects of Zn on both stover and grain yields were only significant in 2015. The nitrogen rate of 60 kg N ha-1 with 2.5 kg Zn ha-1 was optimum for maize production in Minna, Nigeria.

Abstract Plant growth is influenced by seed quality. Seeds need to be treated to prevent pest and disease disorders or to increase seed germination. Soybean planting was carried out in this study by the treatment of varieties and seed pre-treatment application before planting. The study aimed to measure the growth and yield of soybeans by varieties and seed treatment before planting, carried out in the Village of Nggembe, District of Bolo, Bima Regency. The study used factorial randomized block design with two factors. The first factor was soybean varieties consisting of two levels, namely Devon and Dena varieties, and the second factor was the application of pre-planting seed treatments consisting of four levels namely Cruiser, Marshall, Agrisoy, and without seed treatment, each treatment was repeated three times. Observations were made on the performance of agronomic crops and soybean yields. The results showed that the treatment of soybean varieties and the application of seed treatment had a significant influence on plant height and soybean productivity, and both treatments had interactions on parameters of plant height, number of filled pods, weight of 100 seeds, and soybean productivity with the best results successively produced by a combination of Devon-Control, Devon-Marshall, Devon-Agrisoy, and Dena-Cruiser.

<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thrice. The treatment consisted of four levels of ZnSO<sub>4</sub> (0, 5, 10 and 15 kg ha<sup>-1</sup>) and four levels of NPK 15:15:15 (0, 100, 200 and 300 kg ha<sup>-1</sup>). Data collected were subjected to analysis of variance (ANOVA) and means were separated using new Duncan multiple range test at 5 % level of probability. Results obtained showed significant effects of Zn and NPK rates on plant height, number of leaves, yield per plot and yield per hectare. The application of 15 kg ha<sup>-1</sup> Zn and 300 kg ha<sup>-1</sup> (15:15:15) NPK resulted in high yield and high zinc content of seeds.</p>

Field experiments were conducted at the Agricultural Engineering Experimental Farm of The Federal University of Technology, Akure, during 2006/2007 and 2007/2008 seasons to investigate the response of cassava under drip irrigation. The experiment was laid out in a randomised complete block design (RCBD) with three replications. The treatments were based on four different water regimes; with T100 receiving 100% available water (AW), T<sub>50</sub> and T<sub>25</sub> receiving 50% and 25% of AW and T<sub>0</sub> with zero irrigation (control treatment). Disease free stems of the cassava cultivar TMS 91934 were planted at a spacing of 1 m by 1 m. The results indicated that T<sub>100</sub> full treatment produced the highest average total dry matter yield of 49.12 and 37.62 t/ha in 2006/07 and 2007/08 cropping seasons, respectively. However, the average total dry matter production in T<sub>50</sub>, T<sub>25</sub>, and T<sub>0</sub> showed significant differences in their values. Low total dry matter yields of 7.12 and 5.92 t/ha, respectively, were associated with T<sub>0</sub> for the two cropping seasons. The total water use of 1491.75 and 1701.13 mm was recorded for T<sub>100</sub>, while total water use of 729.00 and 651.13 mm were obtained for T<sub>0</sub> in the two cropping seasons. The water use efficiency determined for the two cropping seasons ranged between 7.38 kg/ha and 32.93 kg/ha. The percentages of total water applied from total water use for T<sub>100</sub> were 51.11% and 61.72%, while 14.83% and 17.85% were recorded for T<sub>25 </sub>for 2006/07 and 2007/08 cropping seasons, respectively.

The experiment comprising of four levels of phosphorus, i.e., 0, 20, 40 and 60 kg ha-1 and four levels of zinc, i.e., 0, 5, 10 and 15 kg ha-1 was conducted to investigate the interaction effect of phosphorus and zinc fertilization on yield and yield attributes of green gram [Vigna radiata (L.) Wilczek] cv. SML-668. The treatments were laid out in Randomized Block Design (Factorial) with three replications. The results revealed that plant height, number of pods plant-1, 1000 seed weight, seed and stover yield were increased significantly up to 60 kg ha-1 phosphorus and 10 kg ha-1 zinc treatment levels. Further increase in zinc levels found to decrease the yield and yield attributing traits, indicating antagonistic effect of phosphorus and zinc on each other. The highest plant height, number of pods plant-1, 1000 seed weight, seed and stover yield (at 60 kg P ha-1 and 10 kg Zn ha-1 treatment level) were 48.70 cm, 27.15, 32.70 g, 957.25 and 2398.30 kg ha-1, respectively. Thus, interaction of phosphorus and zinc was significant for all the growth and yield attributing parameters.

Nitrogen (N) fertilizer is considered as one of the most important factors affecting growth and grain yield of hybrid maize. This study was conducted to determine the effects of different rates of nitrogen and varieties on growth and yield of hybrid maize in Lamahi Municipality, Dang, Nepal from June to October, 2019. Three levels of hybrid maize varieties (10V10, Rajkumar F1 and NMH-731) and four levels of nitrogen (160, 180, 200 and 220 kg N ha-1) were evaluated using two factorial randomized complete block design with three replications. The results showed that grain yield and yield attributing traits of hybrid maize varieties increased with the increasing level of nitrogen from 160 to 220 kg ha-1. The application of nitrogen @ 220 kg N ha-1 produced the highest grain yield (10.07 t ha-1), cob length (16.33 cm), no of rows per cob (14.97), no of grains per row (33.37), cob diameter (4.54), thousand grain weight (276.77 g), stover yield (12.91 t ha-1), biological yield (23.00 t ha-1), harvest index (43.80), gross return (NRs. 208940 ha-1), net return (NRs.104488 ha-1) and B:C ratio (2.001). The hybrid maize variety 10V10 produced the highest grain yield (9.35 t ha-1), net returns (NRs. 91740.66 ha-1) and B:C ratio (1.91) accompanied by the highest cob length (16.25 cm), and as number of grains per row (32.35) as compared to other varieties. This study suggested that maize production can be maximized by cultivating hybrid maize variety 10V10 with the use of 220 kg N ha-1 in inner Terai region of Nepal.
