Vegetable development and productivity are influenced by several factors, including the nutrient amounts available. Providing adequate nitrogen favours vegetative growth and promotes increased productivity, in addition to providing greater succulence and improving leaf quality. This work evaluated the effect of nitrogen doses and sources on arugula culture development and productivity. The experiment was conducted on the experimental farm at the State University of Goiás, Ipameri campus, in the municipality of Ipameri, Goiás state (GO). The experiment used a 2 × 5 factorial randomized complete block design, with two sources (normal urea and coated urea), five nitrogen doses (0, 60, 120, 180 and 240 kg ha-1 of N) and four replicates. Plant height, stem diameter, leaf number, fresh shoot matter, dry shoot matter and productivity were evaluated. The results obtained here suggest that nitrogen sources do not influence arugula culture development, but nitrogen doses influence the arugula culture’s productive characteristics.

In Brazil, inoculation with Bradyrhizobium japonicum strains is the main form of N assimilation by soybeans, but there are reports of the use of mineral N as a complement to the demand of this nutrient by the plant. The objective of this work was to verify the effect of different forms and times of N application on vegetative growth and soybean crop yield in northern Mato Grosso. The experimental design was a randomized block design (DBC) with 10 treatments: control (no N application); and in all other treatments 10 kg ha-1 of N was applied, changing season and form of application as: the haul in cover at planting; in V2 at hedging; in V2 via leaf; in V4 at hedging; of N in leaf V4; from N in R1 to hedging; N in leaf R1; in R2 at cover and in R2 leaf. The cultivar used was Bonus from Brasmax®. Vegetative growth was evaluated by height, stem diameter, shoot dry mass, nodulation by number of nodules and yield by variables, number of pods, grains per pod, mass of 1000 grains, and weight. productivity. In practically all variables analyzed, no effects of nitrogen application on soybean crop were verified. The shoot dry mass was higher when nitrogen was applied to V2 via foliar spraying and to V4 in soil cover. In general, although there was no statistical difference between treatments, N application at the beginning of crop development increased soybean yield. The application treatment V2 was the most productive, produced 34% more than the control without N, or 17.34 more bags than the control.

Nine genotypes of castor oil bean (Ricinus cumunis) were evaluated in 2011 and 2012 cropping seasons to determine their consistency of performance at the Enugu State University of Science and Technology, Enugu State. Eight (8) accessions were selected from various locations in the south east, while a standard check was obtained from Ahmadu Bello University Zaria. The study was carried out using a randomized complete block design with four replications. Data was collected on number of days to germination, days to 50% flowering, plant height at maturity, length of primary raceme, length of pistillate region, length of staminate region and number of leaves. The findings from the study showed that Zaria accession flowers within 80 days and significantly (P < 0.05) different from the other eight (8) accessions studied, except Udi for plant height at maturity the significant and comparable large genotypes for all the characters except number of days to germination; number of nodes and length of staminate region implies that there would be adequate gains in selecting the characters. The phenotypic coefficient of variation was found to be higher than the genotypic coefficient of variance for all the character studied indicating the influence of environment towards the total variance. The short height recorded in Zaria and Udi accessions which are at par is of a desirable trait for shorter plants are easier to manage agronomical and it also withstands lodging better than all plants. These accessions based on the agronomic characters studied were found to perform very well in Enugu south-east, Nigeria and is therefore, recommended to be grown in this region.

<p>Field experiment was conducted during the rainy seasons of 2011 and 2012 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, Keffi-Lafia Campus to study the competitive behaviour of groundnut in Sesame-groundnut intercropping system. The experiment consisted of four rates of poultry manure (0, 3.0, 6.0 and 9 t ha<sup>-1</sup>) and two planting arrangement (single alternate row and double alternate row planting arrangement). The eight treatment combinations were laid out in a randomized complete block design with four replications. The results obtained in both the years showed that sesame when grown with groundnut under different rates of poultry manure and planting arrangement appeared to be a dominant crop as indicated by its higher values of Land equivalent ratio, competitive ratio, higher and positive values for aggressivity and area time equivalent ratio. Application of 6 t ha<sup>-1</sup> of poultry manure and double alternate row planting arrangement produced the highest values for all the competition indices measured respectively.</p>

Seedlings of pecan [Carya illinoensis (Wangenh.) C. Koch] grown in perlite culture were treated with N and S in a 5 × 5 factorial in a randomized complete block design to determine the effect of N, S, and N × S interaction on vegetative growth and photosynthesis. Nitrogen and S deficiency symptoms occurred when leaf N and S were < 25 and 1.4 mg·g-1 dry weight, respectively. Photosynthesis was reduced when combined leaf N and S exceeded 35 and 3.7 mg·g-1 dry weight, respectively; growth was reduced when leaf N and S were > 34 and 3.7 mg·g-1 dry weight, respectively. Photosynthesis and growth increased with N supply, but depended on leaf N: S ratio. In plants without visible N or S deficiency, a N: S ratio of ≈9. is proposed to be near the optimum for maximum growth. Comparison of leaf N, S, and the N: S ratio with similar analyses in selected orchards suggests that pecan productivity will increase from S application under field conditions. We conclude that the interaction” of N and S imposes stringent controls on leaf N and S, photosynthesis, and growth.

The practice of winter pruning, held in temperate fruit, has great influence on the development and production of these crops. Changes in pruning system may result in significant changes in the time of harvest, yield and fruit quality.This study aimed to evaluate the effects of time and intensity of pruning in the development and production of blackberry cv. Xavante in organic production system. The experiment was conducted during the crop year 2009/2010 and 2010/2011 in the experimental orchard of the State University of Centro-Oeste (Unicentro)Guarapuava - PR. The experimental design was a randomized complete block design with five replications in a 2x2 factorial design, with two pruning times: early and late, and two intensities of pruning side branches: short and long, a total of four treatments. The variables analyzed were: budding percentage (%), percentage of flowering (%), average fruit weight (g), number of fruits, total soluble solids (°brix), yield (kg), estimated yield (kg ha-1) and early yield (kg plant-1 and %). The time and intensity of pruning did not influence the average fruit weight and soluble solids. Early pruning can be a good strategy to obtain higher yields in early harvest. Early and long pruning is recommended in the most productive terms.

An experiment was conducted during the Agricultural spring seasons 2019 at Abul-Khasib, Basrah. The experiment included 6 treatments combination resulted from the interaction between two plant distances (30 and 60 cm apart), with the addition of three concentrations of vitamin C (0, 20, 40) Mg. liter-1. Randomized Complete Block Design was used in a factorial experiment, mean variations replication compared at 0.05. Results can be summarized as follows: The plant spacing of 60 cm caused a significant effect on the all of the results of vegetative growth (leaves number, surface leaf area, total soluble of carbohydrates contents and chlorophyll) except plant height it gave a significant increase in 30 cm. whereas, the plant spacing of 60 cm gave a significant reduction in the (fruit weight, fruit number. plant-1 and yield. plant-1). Regarding the spraying, levels increased significantly in all component, except pod length it gave a significant decrease in vitamin C levels increased. While there was no significant effect on the interaction between the two studied factors.

Well-known commercial Tomato seeds (Alisa) were obtained from a famous local store. All seeds were grouped into 7 groups (5%, 10%, 20%, 30%, 40%, 50%, and Control), which were equivalent to different Azolla biofertilizers extract. Seeds of each group were left immersed in the equivalent concentration 24 hours before sown in pots with growing media of 1 peat: 1Vermeculite at the beginning of summer season (First week of May). At the time of transplantation to the field, three pots of each group were used for seed germination test; Seeds were transplanted into the field after 6 weeks. After three days of transplantation, control solution (without Azolla biofertilizer) and different Azolla biofertilizers were foliar applied, the process was repeated every 15 days till 45 days after transplanting. Randomized Complete Block Design with three replicates was adapted. Each block consisted of two rows of 1.5m in wide and 5 m long (15 m2/plot), plant spacing was 50 cm, and each replicate has 20 plants. The suggested development approaches for the summer season were conducted all through the developing season. Vegetative growth of the tomatoes was expressed as plant height, plant length, branch flower clusters, and fruits were estimated in five plants/plot after 50 days from the date of transplanting. Tomatoes of control group and Tomatoes that showed a strong vegetative growth were used for feeding Winstar rats. All Biochemical parameters showed a highly significant difference compared to the control group.

This experiment was carried out during 2019 cropping season to evaluate the effect of cow dung rates and Sasakawa technology on the performance of maize in Mubi, Northern Guinea Savannah at Food and Agricultural Organization Tree/Crop production farm Adamawa State University, Mubi. The trial was laid out in Randomized Complete Block Design replicated three times. Data was collected on fifteen characters namely: Number of leaves at 3,6 and 9 weeks after sowing also Plant height at 3,6 and 9 weeks after sowing, Cob length, Number of row per cob, Number of seed per row, Cob diameter, Cob yield, Shelling percentage, Grain weight, Grain yield and 100 Grain weight. Results showed a non-significant difference for all the fifteen (15) traits of maize T1 but T4 have better performance. Also, NL3 and NL6, T3, T4 and T5 outperformed in terms of yield, NL3 showed a highly significant positive correlation with NL6, NL9, PH3 and PH6. Cob yield also has slightly and significantly correlation with NL6, CL and NS/R. The treatments respond to variations in the rates of cow dung application during the trial period. As highly significant and positive correlation was observed for NL3, NL6, NL9, PH3, PH6, and PH9 indicating differences in the treatments applied. The experiment revealed that treatment T1, T4 and T1, T4 for NL3, and NL6 gave highest performance than other treatments, followed by T1 and T4 for NL9 which also did well in that order respectively. Cob yield was observed to performed better in T3, T4 and T5. That translates to a very good grain yields in T3 (27kg/ha-1), T4 (16.20kg/ha-1) and T5 (20kg/ha-1). This might be due to the rates of cow dung applied on these treatments. Hence, it is therefore recommended based on the results of the study to use these range of cow dung in the study area.  Further research is also recommended to be done in this area for adoption by farmers.
