A field experiment was conducted during the 2016 and 2017 dry seasons at Institute for Agricultural Research Farm Kadawa and Zobe Irrigation Fields at to study the influence of intra-row spacing, nitrogen fertilizer and time of its application on the performance of extra early maize. The treatments tested consisted of factorial combinations of three levels of nitrogen (0, 60, and 120 kg/ha), three intra row spacing (15 cm, 25 cm, and 35 cm) and three different times of fertilizer application (at planting+4WAS, 2WAS+4WAS and 2WAS+4WAS+6WAS). The treatments were laid in a split-plot design in four replications with the combination of nitrogen levels and its times of application assigned to the main plot, while intra row spacing assigned to sub-plot. The results of the investigation showed that 25 cm and 35 cm intra row spacing produced the tallest plants, higher number of leaves per plant and number of grains per row at Dutsinma. At Kadawa most of the parameters showed no significant effect on intra row spacing. Nitrogen fertilizer at 120 kg/ha resulted in higher values of growth parameters at both locations. Time of fertilizer application affected growth performance such as plant height, number of leaves per plant and number of days to tasseling and silking at both locations.

The main objective of this study was to investigate the effects of 4 levels of Nitrogen (N) fertilizer (0, 25, 50 and 75 Kg N/fed) on some attributes of Sorghum (Sorghum bicolor L). This study was conducted in the farm of College of Agriculture, University of Bahri-Sudan; during the period 2014-2015. Where the soil is classified as saline with pH ranging from 7.5 -7.8. A randomized completely block designed (RCBD); with 3 replications and four (4) treatments was adopted. All recommended cultural practices were carried out timely. Data; pertaining some plant attributes were collected and analyzed. The result showed that the application of 75KgN/fed has increased both; the average number of leaves as well as the plant height compared to other levels of Nitrogen fertilizer including the control (Figure 1, Figure 2). For the average number of tillers concern, there is non -significant difference between all Nitrogen levels and average number of tillers (Figure 3). The study concluded that the Nitrogen fertilizer has variable effects on the studied agronomic characters, and the application of 75kgN/fed is the optimal level of fertilizer for improving the agronomic traits of Sorghum under Alkadaro conditions.

The dry matter yield of grass forage was increased linearly with nitrogen fertilizer levels of zero, 56, and 112 kg per hectare applied annually in the spring of 1961, 1962, and 1963. Nitrogen levels had little effect on the nutritive value of mature grass forage as indicated by voluntary dry matter intake and body weight gains of beef steers. The apparent digestibility of crude protein increased and that of dry matter and nitrogen-free extract decreased linearly with increasing nitrogen fertilizer rates. Digestibility of crude fiber and ether extract were not altered significantly by nitrogen levels. Forage-carotenes sustained relatively high liver vitamin A levels over a 100-day feeding period. Nitrogen levels had little effect on the rate of liver vitamin A depletion.

Field trials were conducted during 2017 and 2018 rainy season, to investigate the effect of nitrogen fertilizer rates and time of application on the growth and yield of cowpea. The treatment consisted of three levels of urea: 0, 40, 80 kg N ha-1 and the times of fertilizer application: during planting of cowpea, 2 weeks after planting, 4 weeks after planting and 6 weeks after planting; which were factorially combined to form twelve treatments and laid in Randomized Complete Block Design (RCBD). The results showed that, Nitrogen fertilizer rates and time of application had a significant increased on all the growth and yield parameters of cowpea in both years of trials. Application of 80 kg N ha-1 produced the highest number of cowpea leaves (134.45 and 139.23), number of branches (9.45 and 10.54), vine length (78.23cm and 80.12cm) and highest seed weight of 0.52 t ha-1 in both 2017 and 2018 trials. However, the control plots produced plants with the highest number of root nodules (14.78 and 12.49) in both years of cropping. Also, application of nitrogen fertilizer at two weeks after planting of cowpea produced the highest growth and seed weight of 0.68 t ha-1 in 2017 cropping; while in 2018 trial, application of nitrogen fertilizer at two weeks after cowpea planting produced seed yield of 0.69tha-1 which is statistically similar with application of nitrogen fertilizer on the fourth week after planting which produced 0.55 t ha-1 of cowpea seeds. The interaction between nitrogen fertilizer application rates and time of application did not showed any significant difference in cowpea yield and yield components in both years of cropping.

Nitrogen supply and plant population are basic parameters for cereal-legume intercropping. In order to study plant population and nitrogen fertilizer effects on yield and yield efficiency of maize-bean intercropping, a field experiment was established. Three bean plant populations and three nitrogen levels were used. Maize dry matter accumulation decreased with increases in bean plant population. Competitive effect of intercrop beans on maize yields was high at higher plant populations, being decreased by nitrogen fertilizer; application of 50 kg ha-1 N was very efficient in increasing maize cob yield. Intercropping significantly decreased harvest index of beans in all plant population and nitrogen fertilizer situations. The efficiency of intercropping, compared to sole cropping, was evidenced by the values obtained for Land Equivalent Ratio (LER) for biomass, cob and pod yields that increased with increases in bean plant populations and nitrogen fertilizer levels.

A field experiment was conducted during the 2016 and 2017 rainy seasons at Centre for Agriculture and Pastoral Research (CAPAR) of the Usmanu Danfodiyo University Sokoto, Nigeria to study the effect of nitrogen fertilizer and inter-row spacing on herbage yield and some yield parameters of Rhodes grass. A factorial combination of five fertilizer levels (0, 100, 120, 140 and 160 kgNha-1) and three inter row spacing (30, 50 and 70 cm) were used, making fifteen treatments combinations, which were laid out in a RCBD replicated four times. Determination of herbage dry matter yield at the end of 12 weeks post planting was carried out using a 0.25 m2 (0.5 m x 0.5 m) area metallic frame (Quadrat). The herbage was harvested at 5 cm above ground level using hand Sickle from the four plots for each treatment. The samples collected ware oven dried for the determination of dry matter yield, while determination of number of leaves and number of tillers per plant was done by counting the numbers of individual leave and tillers of each of the representative plant sample. The result revealed that, Application of 160 KgNha-1 generally produced higher (P < 0.05) dry matter yield, number of leaves and number of tillers compared to the rest of the treatment, There was no significant (P > 0.05) effect of inter row spacing in both 2016, 2017 and the years combined on herbage dry matter yield, however significant (P < 0.05) effect of spacing was observed in 2016, 2017 and the years combine on the numbers of leaves and numbers of tiller. Inter-row spacing of 70cm showed superiority among the treatments in the herbage yield compositions investigated compared to 50 and 30cm spacings.

This study was conducted to find out the effect of fertilizers on the performance of two hybrids of Euphorbia as indicated by growth and flowering performance. The experimental design with controlled variables was used in the study. The use of organic fertilizers like the use of animal dungs or wastes was proven effective based on the different trials made. In terms of the effect of the fertilizers in the growth performance, there were significant differences on plant height, stem girth, number of leaves, and number of shoots during the 20th, 50th and 80th days of observations. The number of flowers was found to have significant differences in all stages. When measured during the 80th day of observation, significant differences were shown in the size of flowers. However, insignificant difference was shown in the diameter of flower bracts. As to the growth parameters, carabao manure yielded more leaves, and shoots and taller Euphorbia Orchid. It also produced bigger stem girths, wider and longer leaf sizes of Siam Ruby hybrid. As to flowering parameters, carabao manure influenced the growth of more number of flower clusters and bigger sizes of flowers of Euphorbia Orchid. On the other hand, chicken manure also influenced the growth of more number of flowers per cluster of Siam Ruby during the 50th day observation and carabao manure during the 20th day observation.

Study was conducted to find out the effect of various levels (100, 150, 200, 250,300 mg/plant/week) of nitrogen on growth parameters in terms of qualitative and quantitative traits of rose var. Top Secret. Plant growth in general increased with increase in nitrogen levels. Among various levels of nitrogen application, 300 mg nitrogen per plant per week significantly increased all vegetative growth parameters and showed maximum plant height (117.45 cm), leaf area (98.91 cm2 ) and a number of leaves (62.50). Further, flowering parameters like stalk length (83.53cm), bud diameter (2.45cm), bud length (2.55 cm), number of flowers per plant (7.30) as well as per square meter (53.05) were also significantly maximum in plants given nitrogen @ 300 mg per plant per week. Leaf N (2.94 %), P (0.19%), K (1.87%) and chlorophyll content in leaves (4.41mg/g) was also higher with 300 mg N per plant per week. Vase life (10 days) and anthocyanin content in petal tissue (2.09 mg/g) were found the maximum in plants given nitrogen @ 250 mg per plant per week, which was at par with the treatment of nitrogen @ 300 mg per plant per week. Nitrogen should be applied at the rate of 300 mg/plant/week under protected cultivation as the optimum dose for good plant growth and qualitative flower production in rose var. Top Secret under protected cultivation.

Some fruits have difficulties in germination hence their propagation is adversely affected by seed coat dormancy resulting in poor inhibitions and germination potential. This experiment was conducted to determine the effect of pre-treatments on the germination and early growth performance of Moringa oleifera seedlings at nursery stage. The pre-treatment included soaking 24hours, 48 hours, 72hours and control seed not soaked. The experiment was arranged in a Complete Randomize Design (CRD) with four treatments and three replications. A total of 360 seeds (Three replications of 90 seeds) per treatment weresown. The growth parameters such as number of leaves, numbers of branches, stem height, stem width and leaf area were assessed. Data was analysed using descriptive statistics. Germination percentage across the various pre- germination treatments revealed that Moringa seeds soaked for 24hours had the highest percentage germination of 87.7% closely followed by seeds soaked in cold water for 48hours (68.8%). The least percentage germination was observed in Moringa seeds soaked in water for 72hours (53.3%). The results also indicated that pre-treatments of Moringa seeds significantly (P<0.05) improved the performance of the seedlings with regards to number of leaves, branches, plant height, stem width and leaf area with 24hours Moringa oleifera seeds soaked in cold water.
