The cultivation of basil is worth mentioning, because it is a very promising crop. The aim of this study was to evaluate the development of the Basil cultivation, cultivar Tuscan lettuce leaf and Alfavaca red basilican, submitted to different doses of nitrogen. The first factor was composed of six nitrogen doses and one control (0, 40, 80, 120, 160, 200, 240 kg ha-1 of nitrogen), and the Second was composed of two cultivars (Alfavaca red basilican and Tuscan lettuce leaf) with four replicates. The basil Alfavaca red basilican cultivar overcame the cultivar Tuscan lettuce leaf in the plant height and diameter of the stem. In the leaf and shoot dry matter variables, the doses that resulted in the greatest increase of dry matter were 128 and 125.62 kg ha-1 of nitrogen for the cultivar Tuscan of lettuce leaf. Both Alfavaca red basilican and Tuscan lettuce leaf were influenced by nitrogen fertilization and the dose of 120 kg ha-1 of nitrogen has the highest potential in the developmental parameters.

The generation of sludge as anthropic waste is a fundamental pollution problem. However, its conversion to biochar can be an alternative to conventional fertilization for its management and use in agriculture. In this research, we evaluated the effect of the application of different doses of dry sludge (DS) and biochar of pyrolyzed sludge (PS) on the height and dry matter of a tomato (Solanum lycopersicum L.) crop and the nutrient content in the substrate. The biochar was made by rapid pyrolysis, and the substrate and the dry matter of plants were analyzed by different physical and chemical methods. An evaluation of 11 treatments was carried out in allometric measurements of plants and foliar dry matter, in three replicates with two materials (DS and PS) added to the substrate at different levels. The plant height and dry weight were evaluated using an incomplete factorial design in a completely randomized arrangement by performing statistical analysis of multivariate variance. An increase in plant height and dry weight was observed when the doses of DS and PS were increased; however, there were no statistical differences between the two materials. The amount of carbon, organic matter, and Ca concentrations in the dry leaf weight were increased with the addition of DS and PS. Likewise, the use of these materials as conditioners or amendments to agricultural soil at doses of 10-15 t ha-1 may be viable and can contribute to reducing environmental externalities through the use of these anthropic waste materials.

ABSTRACT Information on nitrogen fertilization in growing vines is still a very limited subject, especially for crops on sandy soils in the Pampa Biome in Rio Grande do Sul, where viticulture has expanded considerably in the last decade. This study aimed to assess the impact of N doses on growth of young plants of Chardonnay and Pinot Noir vines and N forms present in sandy soil in the Pampa Biome. The experiment was conducted from October 2011 to December 2012 in a vineyard in Santana do Livramento, in Southern Rio Grande do Sul State, in soil with 82 g kg-1 clay in the 0-20 cm layer. Vines of Chardonnay and Pinot Noir varieties were subjected to applications of 0, 10, 20, 40, 60, and 80 kg N ha-1 year-1. Total N in leaves, SPAD readings, stem diameter, plant height, and dry matter of the pruned material were evaluated in two growth cycles and three times. Soil samples were collected at 0-10 and 10-20 cm depths at four crop growth stages, in which N-NH4 +, N-NO3 -, and total N were analyzed and the mineral N was calculated. The N levels applied to young vines, although they did not provide relevant changes in the N-NH4 +, N-NO3 -, and mineral N contents in the soil, were able to increase the N content in the leaves, increasing plant vigor. because the reason is that there was an increase in stem diameter, plant height, and dry matter of pruned material in most evaluation periods. These parameters suggest better growth patterns and uniformity of young grapevines with possible positive effects in anticipation of production, demonstrating the importance of nitrogen fertilization strategies to the growing vines in the sandy soil conditions of the Pampa Biome.

The goal was to evaluate the effect of nitrogen fertilization on the yield and EAN (agronomic efficiency of nitrogen) of the forage oat crop. To meet this goal, an experiment with a DBCA design was carried out, using 6 treatments: T0 (control), T1 (50-20-60), T2 (100-20-60), T3 (180-20-60), T4 (250-20-60) and T5 (350-20-60), repeated three times, in San Cristobal, Huacrachuco. The evolution of plant height, number of tillers per plant, fresh biomass, dry matter,% fiber and the agronomic efficiency of nitrogen (EAN) were determined. The data were analyzed with ANOVA and LSD test at 5% significance level. Treatments T5 and T4 reached higher values in stem length, higher yields of fresh biomass and dry matter by m2 . Fertilization did not change the number of tillers per plant and the% of fiber. However, the most optimal EAN was achieved with the dose of 100-20-60. Values higher than this dose of N could produce over fertilization without the plant using it efficiently. In conclusion, it is recommended to apply this dose (100-20-60) for having presented the best EAN, although the yields were lower with this dose, it would be the most appropriate for the efficient use of crop N.

Campomanesia adamantium (Cambess.) Berg O. is a native of Savanna, popularly known as gabiroba, guavira, or gabiroba-do-campo, and has many uses, with its fruit being consumed fresh or processed. This study aimed to evaluate different doses of phosphorus and nitrogen in the initial development of gabiroba (Campomanesia adamantium) cultivated in pots. Five doses of phosphorus (0, 100, 200, 300, and 400kg ha-1 of P2O5) and three doses of nitrogen (0, 100, and 200 kg ha-1of N) were tested. The experimental design used was completely randomized in a 5x3 factorial scheme with six replications. The evaluations were carried out 120 days after plant emergence, and the variables analyzed were stem diameter, plant height, and number of leaves. Data were subjected to analysis of variance and F-test. The means were compared by the Tukey test at p0.05. Regression analyzes were adjusted for phosphorus doses. The gabiroba responds significantly to the addition of phosphorus, with the dose of 400 kg ha-1 of P2O5 providing the highest height and the dose of 300 kg ha-1 of P2O5 providing the greatest stem diameter and the number of leaves. Up to 120 days old, gabiroba seedlings do not respond significantly to nitrogen fertilization.

The objective of this study was to determine the effect of nitrogen fertilizer level on growth, dry matter yield and nodulation of Indigofera zollingeriana plant at during the nursery. The experiments were arranged in a complete randomized design consisting of four treatments and four replications. The utilized four levels of the nitrogen fertilizer were 0 (P0), 100 (P1), 150 (P2) and 200 kg N/ha (P3) equivalent to 0, 0.15, 0.23 and 0.30 g N/polybag respectively. The variables in this study included the plant height, stem diameter, number of petioles per plant, length of petiole, number of leaves per plant, root length for each plant and dry matter yield. The results showed that the fertilizer doses increased the plant height, stem diameter, number of leaves per plant, and dry matter yield of leaf, leaf petiole, stem, root and nodule. It could be concluded that nitrogen fertilization was effective in stimulating growth, production and nodulation at early nursery stage, yet higher nitrogen doses (200 Kg N/ha) are ineffective and have inhibitory effects of growth and production. Therefore, high-dose nitrogen fertilizers in legume plants should be avoided because Indigofera zollingeriana is able to fix nitrogen from the atmosphere as in other legumes.

ABSTRACT: Chemical weed control and nitrogen fertilization are common practices in irrigated rice crops. Nitrogen is an essential element for growth and development of plants and may influence herbicide selectivity. In this study, herbicide selectivity was evaluated according to nitrogen application time in irrigated rice crops. The experiment was conducted in the field in a split-plot design with four replications. Treatments were arranged in a factorial scheme: factor A consisted of different nitrogen application times (without nitrogen, all nitrogen applied before flooding, half of the nitrogen rate applied before flooding and the other half after flooding, all nitrogen applied after flooding); factor B consisted of the application of the herbicides quinclorac, bentazon, bispyribac-sodium and carfentrazone-ethyl. Nitrogen application increased plant height and dry matter accumulation in rice plants, while nitrogen application before flooding and split N applications were favorable to the crop. The herbicide bispyribac-sodium causes the greatest injury and the greatest reduction in rice plant height, followed by bentazon and carfentrazone-ethyl, while the lowest injury and the highest grain yield were caused by the application of quinclorac.

  In some leguminous plants, associations with nitrogen-fixing microorganisms allow their nutrition with nitrogen (N) from the atmosphere. This process is known as Biological Nitrogen Fixation (BNF), where through nitrogenase enzymes, N2 is converted to an available form. This process can replace in part, or in total, nitrogen fertilizers. Cowpea bean is a legume species that is recognized for its high capacity to carry out BNF. In the last decades, studies have encouraged small farmers from north and northeast Brazil to use inoculants with rhizobia species since the results of researches have demonstrated that inoculation is an interesting strategy to improve cowpea production. Considering the specific function of molybdenum (Mo) in the N assimilation, different doses of Mo were tested in this study in order to find doses that could improve and enhance BNF. Therefore, this study aimed to compare nitrogen fertilization and BNF in the N assimilation by plants with different Mo doses. Inoculation was performed with the strains UFLA 03-84 and INPA 03-11B. Doses of Mo were applied in seeds and each pot contained five seeds. Thirty-five days after germination, the plants were analyzed for shoot dry matter and fresh matter, N contents and accumulation, as well as the Soil-Plant Analysis Development (SPAD) Index and nodulation in inoculated plants. The different doses of Mo and also the nodulation treatments did not show significant differences in the contents of N. Plants with N fertilization had significant higher shoot dry matter and root dry matter production, in addition to higher N foliar contents and N accumulation. Therefore, BNF was not as efficient as nitrogen fertilization in the evaluated experimental conditions using cowpea beans.

Abstract A field experiment was carried out at the Second Agricultural Research and Experiments Station of the College of Agriculture/University of Al-Muthanna in Al Bandar region, during the winter season (2019-2020), in order to know the effect of nitrogen fertilization and seed rate on the production of dry matter for barley crop, and the experiment was applied according to the arrangement of the split plates. According to the design of randomized complete blocks with three replications, the number of experimental units was 120 units. The experiment included the secondary factor of five seed quantities (40, 60, 80, 100 and 120 kg ha−1) and the main factor included 4 levels of nitrogen fertilizer (0, 50, 100 and 150 kg ha−1). The results showed that the rate of seed were significantly superior in most of the growth characteristics and dry matter of the barley crop, where the rate of seeds 80 kg ha-1 outperformed in the characteristics of plant height, dry weight of the stem, dry weight of leaves, dry weight of ears and dry weight of the plant, where their averages were (96.64 cm, 10.34 g, 7.20 g, 4.78 g and 22.3 g) respectively, while the level of 120 kg ha−1 seed rate outperformed in increasing the area of the flag leaf, which amounted to 23.67 cm 2, and the lowest seed level 40 kg ha-1 gave an increase in the length of the spike, which reached 7.06 cm. As for nitrogen fertilizer levels, the levels were significantly higher in all studied traits, where the amount of fertilizer 100 kg ha−1 outperformed in all studied traits, plant height (100.20 cm) and area leaf flag (24.38 cm 2), the number of tillers (8.38 tillers Plant−1, the length of the spike (6.92 cm), the dry weight of the stem (10.84 g), the leaves (7.29 g), the spikes (5.38 g), and the dry weight of the whole plant (23.51 g). As for the interaction between the rate of seed and nitrogen fertilization, the combination (80 kg ha−1 seed * 100 kg ha−1 nitrogen) outperformed and gave the highest averages for most of the studied traits. And the weight of the full bat where their averages were (13.20, 10.51, 7.37 and 31.07 g) respectively.

Given the high costs of agricultural production, especially due to the price of fertilisers, particularly nitrogen, the use of inoculants to supply nitrogen to soybean crops is a widely recommended practice. The objective of this study was to evaluate the feasibility of applying inoculants through seed and planting furrow in soil previously cultivated with soybean and Brazilian native “cerrado” biome soil under greenhouse conditions. Seven treatments were tested: 1) inoculation via seed (inoculant + fungicide + micronutrient), 2) treatment via seed (fungicide + micronutrient), 3) control (only seed), 4) inoculation via furrow-dose 1 (recommended dose), 5) inoculation via furrow-dose 2 (twice the recommended dose), 6) inoculation via furrow-dose 3 (three times the recommended dose) and 7) inoculation via furrow-dose 1 + seed inoculation. We evaluated plant height, fresh and dry matter weight of the aerial part and nodules, number of total, viable and non-viable nodules, number of pods per plant and grain yield. Inoculation was more effective when used in cerrado soil, but soybean performance in treatments without inoculation was higher in previously cultivated soil. Application through furrow proved to be a viable practice due to the similarity of the results obtained with the traditional application by seed.

Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66),  number of pods plant-1 (41.56), number of seeds pod-1 (58.83),  seed yield    (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87),  number of pods plant–1 (46.13),  number of seeds pod-1 (56.67),  seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.
