ABSTRACT: The use of leguminous green manure can be an alternative for the region agricultural systems due to its ability to incorporate significant amounts of nutrients into the soil through decomposition and nutrient release from biomass. This study aimed to evaluate the decomposition rates and nutrient release of six leguminous green manure species ( Crotalaria juncea , Canavalia ensiformes , Cajanus cajan , Crotalaria spectabilis , Dolichos lablab and Mucuna deeringiana ) in an area of the Jaguaribe-Apodi agricultural region, Brazil. Experiment was carried out under field conditions in a randomized block design with five replications. Decomposition and nutrient release from leguminous biomass were monitored by sampling at 30, 60, 90, 120, 150 and 180 days after installing litter bags. In general, Crotalaria spectabilis and Canavalia ensiformes showed higher decomposition and nutrient release rates and they are the most promising for the region in the conditions of this study. However, for greater persistence of residues in the soil, Crotalaria juncea is more recommended.

Increased productivity of sugarcane in upland area can be done through the implementation of the integration of manure with a high dose of inorganic fertilizer in the double rows and twice plant populations of single row (“double rows double seeds”) planting arrangement. Limited availability of manure and inorganic fertilizer entails the replacement of manure with green manure fertilizer. The research was aimed to obtain a green manure as replacement manure that can be intercropped in the double rows double seeds planting arrangement. The experiment was done in the Asembagus Experimental Station, Situbondo, East Java on January to December 2014 for plant cane (PC) and from January to December 2015 for ratoon cane (RC). Treatments were arranged in a Randomized Block Design time for replication. The treatment includes (1) the four rows of Crotalaria juncea, (2) two rows of Crotalaria juncea, (3) four rows of peanuts in width between rows of sugar cane, (4) manure, and (5) no organic fertilizer. The results showed that the integration of organic fertilizer with a low dose of inorganic fertilizers increases productivity and sugar yield 5.20 to 41.78% and 33.33 to 69.90%, respectively in PC and 7.33 to 32.67% and 5.74 to 29.61%, respectively in RC from no organic fertilizer. Four rows of Crotalaria juncea could replace the role of manure in improving the productivity and sugar yield for PC and two rows of Crotalaria juncea for RC.

ABSTRACT Green manure promotes efficient suppression of weeds, but green manure species can exhibit distinct behaviors, depending on the environmental conditions. This study aimed to evaluate the potential of soil mulching and weed suppression by spring/summer green manure species grown in the spring/summer season, at different growth stages and after management (cut), for 90 days during the cassava crop cycle. The study was carried out in the 2010/2011 season, in a system managed under agroecological principles. The treatments consisted of different green manure species and arrangements: Crotalaria juncea, Cajanus cajan, Canavalia brasiliensis, Canavalia ensiformis, Pennisetum americanum, Crotalaria juncea and Pennisetum americanum intercropped; Mucuna aterrima, Sorghum bicolor, a mixture of all the green manures in study and a control plot under fallow. The experiment was arranged in a randomized block design with four replications. The evaluations of the soil cover either by the green manures or weeds were performed at 45, 90 and 105 days after the emergence of the green manures. The cassava crop was planted under reduced tillage system at 11 days after the cut of the green manures. The percentage of soil covered by weeds and the dry matter produced were evaluated at 30, 60 and 90 days after planting. The results showed that the green manures had a suppressive effect on weeds during their life cycle, as well as during the first months after its management (cut), composing the mulch.

Animal grazing in integrated crop-livestock systems (ICLS) results in continuous nutrient release to forage plants and crops in succession. This study aimed to assess sheep dung composition and decomposition rates under distinct grazing intensities and at different development stages of Italian ryegrass pasture (Lolium multiflorum Lam.), and to evaluate dung phosphorus (P) and potassium (K) release dynamics during two annual ICLS cycles (2015 and 2016) in southern Brazil. Treatments consisted of two grazing intensities (moderate and light) and two pasture development stages (vegetative and post-flowering), arranged in a randomized complete block design with split-split-plots and four replicates. Dry matter (DM) decomposition and P and K release rates were determined using litter bags with sheep dung. Grazing intensity did not affect sheep dung composition. Forage consumed at different development stages altered sheep dung composition, decomposition, and P and K release rates. Dung sampled at pasture vegetative stage showed P and K contents 16% and 7% higher, respectively, than dung from the post-flowering stage. Dung collected at pasture post-flowering stage had 26% more cellulose and 34% more hemicellulose compared to dung from the vegetative stage in 2016. P and K release was greater for dung from pasture vegetative stage, reaching 3.7 and 12.9 kg ha−1 of P and K, respectively. Further evaluations are still needed considering the quantification and release of nutrients in each of the different compartments (pasture, urine, and dung residues) that compose the system.

The research compared biomass production and nutrient release in an alley cropping system in two collection methods, the litterbag method and the direct collection method (Morley, Bennett, & Clark, 1964). The system was implemented in 2015 at 2017, at the Maranhão Federal University, Maranhão, Brazil. The experiment was a randomized block design with four treatments, consisting of leucaena+sombreiro (Leucaena leucocephala and Clitoria fairchildiana), leucena+acacia (Leucaena leucocephala and Acacia mangium), gliricidia+sombreiro (Gliricidia sepium and Clitoria fairchildiana) and gliricidia+acacia (Gliricidia sepium and Acacia mangium). In order to determine the remaining dry matter, nutrient release (N, P, K, Ca, Mg and Mn), the decomposition constants and the half-lives times of plant residues, 100 g of fresh material were conditioned in litterbags (50 g of each species), arranged on the soil surface. The second method was done by randomly throwing a collector on each plot in the same dimensions of the litterbags (0.40 x 0.40 m) and collecting the litter. For the two methods samples were collected at 0, 30, 60, 90 and 120 days after the start of the experiment. The litterbags method showed a higher C/N ratio at day 30 up to 120 days, which implies that this method is providing a different environment from the litter, where it would be overestimating the C/N ratio and retarding the decomposition. The G+S and G+A combinations were more rapidly decomposed than the combinations of L+S and L+A. The following order of release was established for the litterbags method: P > N > K > Ca > Mn > Mg, and for the method of collecting the litter: N > P > Ca > Mg > K > Mn.

In the Central Altiplano of Bolivia, the production of forage oats is important for the feeding of herbivorous livestock; however, the yields obtained at the producer level register low averages in dry matter. The objective was to evaluate the agronomic performance of three oat varieties, with levels of ground coca leaf as green manure, at the Kallutaca Experimental Center in the department of La Paz. A randomized block design was applied with a divided plot arrangement with four replications. The factors were oat varieties (Aguila, Gaviota and Texas) and levels of ground coca (0, 30 and 60 t ha-1), with variables days to emergence, number of tillers, plant height and dry matter yield. The results at days to emergence show differences in time 60 and 0 t ha-1 with 14 and 11 days. In relation to the number of tillers per plant, in varieties the behavior is similar with an average of 7 tillers; in relation to interaction, the values show significance. In plant height, the means recorded for the Texas variety were 137.10 cm, in the interaction the values were equal. In dry matter, there were significant differences in 60 and 30 t ha-1 with 16 427.27 and 15 281.82 kgDM ha-1, the Gaviota variety with 14 706.06 kgDM ha-1. The treatments influenced the agronomic behavior of the variables studied, the levels of green manure affected oat yield, mainly the number of tillers, which in turn affected the dry matter yield, finally the oat varieties have a differential behavior with the change in the levels of green manure.

The intensive use of the soil, associated with the application of chemical fertilizers, contribute to degradation processes that affect soil quality and crop production. The use of techniques that contribute to soil conservation and reduction of external inputsis important for the success of the agriculture, and hedging is an alternative. The objective of this study was to evaluate the phytomass production nutrient accumulation and contents, as well as rate of decomposition of different species used as cover plants. The experimental design was randomized blocks, with nine treatments distributed in three blocks. The treatments were: Canavalia ensiformes (L.) DC., Crotalaria spectabilis Roth, Crotalaria ochroleuca G. Don., Crotalaria juncea L., Dolichos lablab L., Stizolobium niveum (Roxb.) Kuntze, Stizolobium aterrimum Piper &amp; Tracy, Neonotonia wightii (Wight &amp; Arn.) J.A. Lackey and Pennisetum glaucum (L.) R.Br. The most recommended species as cover plants are C. ochroleuca and C. spectabilis for they produce more dry matter on the tops, 5.89 and 4.04 kg ha-1, in addition to greater accumulation of nutrients. C. ochroleuca and C. spectabilis had higher accumulation of N, P, K, Mg and S, and soil coverage with those species can be a good source of green manure. The recommended species for the highest coverage rate are: N. wightii; S. niveum and S. aterrimum. The recommended species for the lowest rate of decomposition are: S. aterrimum; S. niveum; P. glaucum and C. ochroleuca (0.245; 0.260; 0.264 and 0.276% month-1).

O conhecimento da interação entre a espécie e a época de semeadura é um importante instrumento para avaliar a capacidade agronômica de espécies de leguminosas tropicais. Com o objetivo de avaliar o efeito da época de semeadura na produção de biomassa de adubos verdes foi conduzido um experimento em blocos casualizados no esquema de parcelas subdivididas, com quatro repetições. As parcelas foram compostas pelas espécies Crotalaria juncea, Crotalaria spectabilis, Cajanus cajan (L.) Millsp, Cajanus cajan, Dolichos lablab, Canavalia ensiformis e Mucuna aterrima e as subparcelas por três épocas de semeadura: 17 de maio, 02 de junho e 20 de junho. A produção de matéria verde foi diminuída com o atraso na época de semeadura, exceto para as espécies Crotalaria juncea, Crotalaria spectabilis. As espécies Crotalaria spectabilis, Cajanus cajan (L.) Millsp e Mucuna aterrima não sofreram influência da época de semeadura para a produção de matéria seca, podendo ser semeadas em qualquer uma das três épocas avaliadas. O atraso na época de semeadura diminuiu a produção de matéria seca das espécies Cajanus cajan, Dolichos lablab e Canavalia ensiformis. A relação percentual matéria seca por matéria verde diminuiu com o atraso da época de semeadura para as espécies de ciclos menores e aumentou para as espécies de ciclos mais longos, exceto para o Canavalia ensiformis.

Studies carried out with the use of gliricidia biomass found that green manure contributes to increasing the productivity of forest crops when compared to the incorporation of other legumes. This study aimed to evaluate the viability of vegetative propagation by cuttings in the development of rooting and budding of Glyicidium sepium in different concentrations of indolebutyric acid (IBA). The experiment was carried out in a greenhouse with an entirely randomized block design and increasing concentrations of IBA 0, 625, 1250, and 3000 mg.L-1 with six replicates. The cuttings were standardized in length and diameter, then treated with sodium hypochlorite and immersed in different concentrations of IBA. The parameters plant evaluated were the sprouts number, sprouts length, sprouts diameter, sprouts dry weight, and roots dry weight. The concentration of IBA was shown to be effective in increasing all parameters studied at the IBA concentration of 2100 mg.L-1, and the higher concentrations did not offer any cost-benefit advantages for the production of gliricidia by cutting.

ABSTRACT The experiment was conducted in (Integrated Agroecological Production System in Seropedica-RJ) Sistema Integrado de Produção Agroecológica (SIPA), Seropédica-RJ, to evaluate the effect of two maize populations in relation to baby corn productivity and shoot mass, to determine the contribution of pre-cultivated maize, green velvet and organic topdressing fertilization in the agronomic performance of cabbage (Brassica oleracea var. capitata). The experimental design consisted of randomized blocks with three treatments (maize population of 100,000 and 200,000 plants ha-1 and green velvet at 100,000 plants ha-1) and eight replicates. After that, cabbage was transplanted in the straw of these species, adopting a randomized block design allocated in split plots, totalizing six treatments, being three pre-cultivation practices and two organic topdressing fertilization doses (with or without 50 g fermented organic compost per planting hole). Considering “baby corn” productivity, no differences were observed compared to maize populations, with an average productivity of 822.5 kg ha-1. Green velvet pre-cultivation obtained the highest shoot dry mass (8.4 t ha-1). Cabbage crop was improved by green velvet pre-cultivation, reaching 60.7 t ha-1 and organic topdressing fertilization, reaching 60.4 t ha-1; however, in the presence of green velvet straw, topdressing fertilization did not promote additional yield benefit of this crop. Thus, we noticed that green manure using green velvet increased cabbage productivity, submitted to organic management, when compared to maize pre-cultivation, making it able to replace organic topdressing fertilization.
