Field experiment was conducted at the Institute for Agricultural Research Farm at Samaru, Nigeria in 2008 and 2009 rainy seasons to investigate the residual nitrogen contributions by four legume crops (soyabean, cowpea, lablab, and groundnut) to the growth and development of succeeding maize given four levels of nitrogen fertilizer (0, 40, 80, and 120 kg N ha−1). In 2008, the treatments consisted of four legumes, maize and a fallow period. The six treatments were laid out using randomized complete block design replicated four times. In 2009, maize crop was planted on the previous crops’ plots and fallow. The experimental design used was split-plot with previous legumes, maize, or fallow as main plots, and the four nitrogen fertilizer treatments as subplots. Results obtained showed that nitrogen availability in the top soils of the previous legumes and fallow compared with that of maize plot was increased by 250, 200, 170, 107 and 157% after lablab, groundnut, cowpea, soyabean and fallow, respectively. Maize grown on previous lablab plot significantly recorded higher growth characters compared with maize following other legumes and fallow. Growth of maize was highest with the application of lower rates of nitrogen after lablab and groundnut compared with maize after maize.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.

Effect On Yield

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1 , respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.

A field experiment was carried out at El-Kod Agricultural Research Station, Abyan Delta, Abyan Governorate during the seasons 2014 and 2015 in soil sandy silt to assess four levels of nitrogen fertilizers (0, 55, 110 and 165 kg N/ha) utilizing urea fertilizer (46% N) on some crop characteristics and efficiency of nitrogen application on two local cultivars of sorghum (Sorghum bicolor L. Moench). Split plot design was applied in four replicates. Fertilizer levels were distributed in main plots whereas, the cultivars in subplots. The results revealed significant differences between cultivars Benny and Saif in all characteristics during the two seasons. Cultivar Benny was significantly superior to cultivar Saif in all crop characteristics, except the length of spike which was significantly superior in Saif cultivar compared to cultivar Benny in both seasons. The increase in nitrogen level led to significant increase in all parameters of crop growth under study in both seasons, where the highest dose of nitrogen (165 kg N/ha) gave highest grain yield (3013 and 3201 kg/ha) in both seasons respectively, while the efficiency of nitrogen utilization declined with increased level of nitrogen application and highest value in nitrogen efficiency (12.78 kg grain/kg N). The interaction between cultivars and nitrogen fertilizer showed significant differences in terms of all studied parameters during both seasons. The cultivar Benny responded to high level of nitrogen (165 kg N/ha) and gave high grain yield (3640 and 3305 kg/ha) in both seasons respectively. The results yielded significant effect for efficiency of nitrogen application on grain yield between the cultivars, the levels of fertilizers and their interaction in the first season whereas, no significant differences were detected in the second season.

<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

Durum wheat has a comparative adaptive advantage over bread wheat under hot and dry conditions. Accordingly, it feeds millions of people in the Middle East and North Africa. Under these conditions, the deficiency of nutrients, including micronutrients, is a major concern for many reasons, including calcareous soil under drought stress conditions. Therefore, growth, yield, iron (Fe) and zinc (Zn) concentration in durum wheat cultivar grains were investigated. A factorial experiment based on a randomized complete block design with three replications was conducted in the Dryland Agricultural Research Institute (DARI) - Moghan. The first factor comprised spraying at four levels, including the control and foliar spraying with Fe, Zn, and Fe+Zn and the second factor consisted of genotypes at four levels: Dehdasht (G1), Seymareh (G2), and two new genotypes (G3 and G4). Solutions of Fe and Zn fertilizers were sprayed at the tillering, early ear emergence, and milk stages, with a ratio of 2 and 1.5 g fertilizer/1000 ml solution (W/V), respectively. The results showed that genotypes G1, G3 and G4 produced higher grain yield per square meter than G2. This increase was due to the higher weight of 1000 grains in G3 and G4 genotypes and 1000-grain weight with a higher grain number in G1. G1 and G2 had greater spike length, number of grains per spike and spikelet than G3 and G4 genotypes. In all studied traits, except Fe and Zn concentration, the combination of Fe+Zn showed the highest and control had the lowest performance. Also, the application of Zn was superior to Fe. The highest Fe concentration of G1, G2, G3, and G4 was observed at Fe+Zn, control, Zn, and Fe levels, respectively. The highest Zn concentrations were observed in the G3 genotype when only Zn was used or in combination with Fe. According to the results, the Fe and Zn spray application increased durum wheat yield on Fe and Zn deficient soil.

Trees sampled from a loblolly pine mid-rotation fertilization trial were used in this study. The study was laid out in a randomized complete block design with four levels of nitrogen fertilizer as treatments: control (000N), 112 (112N), 224 (224N), and 336 (336N) kg/ha of nitrogen, with each treatment replicated in 4 blocks. Two trees were destructively sampled from each plot giving a total of 32 trees. Bolts 0.6 m in length were collected from each tree (3 bolts per tree); with the midpoint of each bolt at heights of 2.4, 7.3 and 12.2 m from the base of the tree (each bolt represented the midpoint of standard 4.9 m saw logs). Static bending samples with dimensions 25 by 25 by 406 mm (radial, tangential and longitudinal dimensions respectively) were cut from the bolts that included the 25 mm of wood produced immediately following fertilization. Data on modulus of elasticity (MOE, stiffness) and modulus of rupture (MOR, strength) were collected from clear static bending samples. Based on the analysis of variance, no significant treatment effect was observed on MOE and MOR. However, MOE and MOR decreased in wood produced immediately after fertilization for trees which received the highest level of fertilization (336N). A decreasing trend in MOE and MOR with height was also present.

Abstract To evaluate the interaction effects of planting date and different levels of nitrogen fertilizer on sorghum (Sorghum bicolor var. Speed feed) forage production, an experiment was conducted in split plots based on a complete randomized block design in Agricultural Research Station of Khorramabad, Lorestan province, Iran. The experimental treatments comprised of three nitrogen fertilizer levels of control (N0), 100 (N1), and 150 kg per hectare (N2), assigned to main plots and three sowing dates of T1 (June, 10th), T2 (June 26th) and T3 (July 11th) assigned to subplots. Results showed that in sum of two harvests, the yield of hay, forage, leaf and shoot hay weigh in second planting date and N2 and N3 level of fertility was higher than all treatments. In the case of quality treatments the percent of crude protein in first harvest had the most amounts in first and second planting date and N1, N2 and N3 fertility levels. Crude fiber percentage in first harvest of second planting date was highest in N1, N2 and N3 levels of fertility. Treatment interactions had not any significant effect for crude fiber. The most ash percent was observed in first harvest and N1, N2 and N3 fertility level. In second harvest time N2 and N3 fertility levels were superior to the rest. Also, fat percentage in first and second planting date and N1, N2 and N3 increased than the control fertility treatment.

Potassium and sulfur are among the most important nutrients limiting sesame production. EthioSIS soil testing map indicate that nutrients such as K and S are deficient in the study site. Study was carried out to investigate response of sesame to K and S application at Humera Agricultural Research Center, Kafta Humera district, Tigray, Ethiopia in 2016 main cropping season. Treatments consisted four levels of potassium (0, 20, 40 and 60 kg K2O ha-1 as KCl) and four levels of sulfur (0, 20, 40 and 60 kg ha-1 as CaSO4.2H2O). The experiment was laid out as Randomized Complete Block Design (RCBD) in factorial arrangement with three replications using Setit-1 sesame variety. Soil sample was taken, result of soil analysis revealed that the soil was clayey textural class, neutral in soil reaction (pH = 7.35), low organic matter content (0.73%), very low total N (0.03 %) and very low available P (0.74 mg kg-1), high  soil cation exchange capacity (CEC) (40 cmol(+) kg-1), medium exchangeable K (0.26 cmol(+) kg-1) and low extractable sulfur (4.78 mg kg-1). Maximum sesame grain yields (1371.67 kg ha-1) was obtained from plot treated with 20 kg K2O ha-1 + 40 kg S ha-1 which resulted 145.3% increase over the control  plot`s yield. From plots fertilized with K and S levels at a rate of 20 kg K ha-1 and 40 kg S ha-1 was obtained higher yield of sesame. It is conclude, therefore, it will be good to promote K and S for further demonstration.

Succession crops in no-tillage system can improve the soil attributes, thus favoring the growth and development of maize (Zea mays L.) and contributing to grain yield increment. The objective of this work was to verify the effect of succession crops on growth and development of maize planted in the summer and the influence on grain yield. For the study, a long-term experiment was implemented, beginning in September 2009, in dystroferric Red Latosol, on the Experimental Farm of the School of Agricultural Sciences of the Federal University of Grande Dourados (UFGD), located in the municipality of Dourados, Mato Grosso do Sul state. This article presents data collected from the 2017/2018 crop season. Randomized block design was used, with ten treatments and four replications. The treatments consisted of the crops preceding maize, such as millet (Pennisetum glaucum L.), oilseed rape (Brassica napus), oat (Avena sativa), safflower (Carthamus tinctorious), niger (Guizothia abyssinica), vetch (Vicia sativa), sunn hemp (Crotalaria juncea), and forage radish (Raphanus sativus). The predecessor crops positively influence dry matter mass of the aerial part of the plant, dry matter mass of 1000 grains, and productivity of the summer maize crop planted through the remains of straw (residues) of millet, oat, niger, sunn hemp, vetch and forage radish.
