“…The fact that nitrogen did not affect the mass of 100 grains was also verified by Kolling and Ozelame (2017), who, using doses of 0 kg ha -1 , 25 kg ha -1 , 50 kg ha -1 , and 75 kg ha -1 of nitrogen, found no effect on seed mass. Other authors also found no differences in the effect of the nitrogen dose on the mass of 100 grains, such as Moreira et al (2013); Guimarães et al (2017), and Sabundijian et al (2016).…”

“…The variable number of grains per plant was also not influenced by the doses of nitrogen and irrigation levels, observing the average value of 85.02 (TABLE 5). Sabundijian et al (2016), testing doses of 0 kg ha -1 , 40 kg ha -1 , 80 kg ha -1 , and 120 kg ha -1 , also found no significant effect of nitrogen on the number of grains per plant.…”

“…In a study conducted by Moreira et al (2013) analyzing nitrogen doses (0 kg ha -1 , 40 kg ha -1 , 80 kg ha -1 , and 120 kg ha -1 ) in irrigated beans, they found that a linear increase caused by nitrogen doses in sowing in grain yield occurred where, for each kg of this nutrient, there was an increase of 3.679 kg ha -1 in this variable, with a maximum yield of 2404 kg ha -1 . Sabundijian et al (2016), testing doses of 0 kg ha -1 , 40 kg ha -1 , 80 kg ha -1 , and 120 kg ha -1 , in coverage with the application in a total area of Rhizobium tropici, found a significant effect on grain yield in the first year of the experiment with the maximum point of production using 60 kg ha -1 of nitrogen. However, in the second year of the experiment, the author found no statistical differences with nitrogen doses, showing the difficulty of dynamics in the management of this nutrient.…”

Irrigation makes it possible to increase productivity in bean crops, but if mishandled, it can increase production costs and promote the leaching of nutrients, especially nitrogen, a nutrient that is fundamental for the development of the crop. Given the above, the objective of this study was to evaluate the yield of common beans subjected to different doses of nitrogen and water depths in the region of Uberaba – MG, Brazil. The experiment was conducted at IFTM – Campus Uberaba, in randomized blocks, consisting of four levels of irrigation (deficits of 15 %, 30 %, and 45 % and a factor without water deficit) and four doses of nitrogen (50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1) applied in stage V4 of beans. The cultivar used was BRSMG Majestoso. There was no interaction between irrigation levels and nitrogen doses for the variables studied. Nitrogen doses influenced linearly only leaf nitrogen content. The water deficit of 9.72 % was favorable to achieve maximum grain yields and favors the number of pods per plant. The plant mass in R6, a mass of 100 grains, hydration, and thermal sum declined linearly with increased water deficit.

“…This result may indicate a favorable element for its use in the treatment of seeds, since one of the advantages of the promoters is the reduced value for the acquisition of the products, with little impact on the cost of final production, in situations of large-scale production. Research, Society and Development, v. 11, n. 6, e15511629094, 2022 (CC BY 4.0) Sabundjian (2016) demonstrate that the effects provided by A. brasilense are derived from morphological and physiological changes in the roots of inoculated plants, resulting in an increase in the absorption of water and nutrients.…”

The objective of this work was to verify the effect of humic acid application in association with the growth-promoting bacteria Azospirilum brasilense and Bacillus subtilis on seed germination and on the initial development of white sesame seedlings. The research was carried out in the Laboratory of Seed Technology and Matology (LaSeM), at the University of the State of Mato Grosso – Campus de Alta Floresta. The treatments were composed by the combination of doses of 0, 100, 200, 300, 400 and 500 mL 100 kg-1 of commercial product containing humic acid, composed of 18% of humic acid, in addition to treatment with the bacteria Azospirillum brasilense and Bacillus subtilis, in the same doses as humic acid. The variables analyzed were germination percentage, aerial and root length, fresh and dry mass of the roots. Humic acid showed promise in the cultivation of white sesame.

Introduction and aimsIn the context of increasing population and decreasing soil fertility, food security is one of humanity’s greatest challenges. Large amounts of waste, such as sewage sludge, are produced annually, with their final disposal causing environmental pollution and hazards to human health. Sludge has high amounts of nitrogen (N), and, when safely recycled by applying it into the soil as composted sewage sludge (CSS), its residual effect may provide gradual N release to crops. A field study was conducted in the Brazilian Cerrado. The aims were to investigate the residual effect of successive applications of CSS as a source of N in the common bean (Phaseolus vulgaris L. cv. BRS Estilo)-palisade grass (Urochloa brizantha (A.Rich.) R.D. Webster)-soybean (Glycine max L.) rotation under no-tillage. Additionally, N cycling was monitored through changes in N metabolism; the efficiency of biological N2 fixation (BNF) and its implications for plant nutrition, development, and productivity, was also assessed.MethodsThe experiment consisted of a randomized complete block design comparing four CSS rates (10, 15, 20, and 25 Mg ha-1, wet basis) to a control treatment (without adding mineral or organic fertilizer) over two crop years. Multiple plant and soil analyses (plant development and crop yield, Falker chlorophyll index (FCI), enzymatic, biochemical, 15N natural abundance, was evaluated, root and shoot N accumulation, etc.) were evaluated.Results and discussionResults showed that CSS: i) maintained adequate N levels for all crops, increasing their productivity; ii) promoted efficient BNF, due to the stability of ureide metabolism in plants and increased protein content; iii) increased the nitrate content and the nitrate reductase activity in soybean; iv) affected urease activity and ammonium content due to changes in the plant’s urea metabolism; v) increased N accumulation in the aerial part of palisade grass. Composted sewage sludge can be used as an alternative source to meet crops’ N requirements, promoting productivity gains and N cycling through forage and improving N metabolism.
