“…Among the plant species, C. spectabilis showed smaller phytomass production potential under the study condition. This can be explained because C. spectabilis is an erect and small size culture (Tivelli et al, 2013), besides the fact of having a C3 metabolism that presents a slower vegetative growth, as well as a shorter assimilation of atmospheric C (Dantas et al, 2015).…”

The plant residues left on the soil surface in no-tillage systems are an important source of nutrients for the subsequent crops, particularly under tropical climate. The aim of this study was to evaluate the cover plants grown during the off-season on development and productivity of maize cultivated in the first crop in no-tillage system. The experiment was conducted in the 2010/11 and 2011/12 agricultural years, in the experimental area. The experimental delineation used was the random blocks with four repetitions and eight treatments (as cover crops) consisted as follows: maize (alone), maize + Urochloa ruziziensis, sorghum, Crotalaria spectabilis, Urochloa ruziziensis, forage turnip, millet and fallow. The cover plants were placed in "Litter Bags", which were fixed to the ground in each plot and collected at 0, 15, 45, 75 and 115 days after the handling of the covers. Plant height, first ear insertion height and grain productivity were assessed in the culture of maize. Maize in single cropping or intercropping with Urochloa ruziziensis were good option to cover plants for the no-tillage system, due to maintenance of straw on the soil surface. Maize seeded on crop residues of C. spectabilis and U. ruziziensis showed more plant height; crop residues of forage and U. ruziziensis provided an increase maize culture productivity grown in succession.

“…Several research studies have revealed the possibility of intercropping vegetables with green manure, such as broccoli with velvet bean (Siqueira et al, 2009), taro with pigeon pea (Oliveira et al, 2006), taro with dwarf velvet bean, and Crotalaria spectabilis Roth (Tivelli et al, 2013) with sunn hemp (Oliveira et al, 2004;Silva et al, 2006;Oliveira et al, 2007). However, these studies were performed with the vegetables being cultivated in the interim form and banded with green manure.…”

Intercropping using legumes is one of the ways to protect the main crop, and in long term improve the physical and chemical properties of the soil. The aim of this work was to evaluate the intercropping of Colocasia esculenta (L.) Schott (taro) and the tropical legume Crotalaria juncea L. (sunn hemp), cutting sunn hemp at ten periods during the cycle. The experiment was carried out under field conditions between 09/23/2010 and 06/04/2011. It consisted of 11 treatments related to the 10 cutting times of sunn hemp (55, 70, 85,100, 115, 130, 145, 160, 190, and 220 days after sowing - DAS) plus a control of taro with no sunn hemp. During the cycle, taro was evaluated for plant height and incidence of leaf burn. At the time of cutting the sunn hemp, the plant height, fresh and dry matter masses, and nutrient content of the biomass were calculated. During taro harvest, we evaluated the productivity of the mother rhizomes and classified the cormels. Taro plants shaded by sunn hemp showed a lower incidence of leaf burn. The sunn hemp cut from 145 DAS onwards affected the yield of comercial rhizomes and total and agroeconomic indexes. Sunn hemp cut up to 130 DAS provided better performance of taro, without compromising productivity and economic indicators, with the highest amounts of N and K observed in the biomass cut at 115 DAS.

“…Tivelli et al (2013) who verified 27 green fruits per okra plant, grown in a consortium system with two rows of crotalaria plants. The plants irrigated with 100% ETc showed better results than those irrigated with 50% ETc, with and without mulching, indicating that economically cultivated of okra under semi-arid climate conditions should be irrigated.The okra yield as a function of soil organic matter doses in the absence and presence of mulching showed yields of17,168.43 and 8,365.14 …”

The objective of this experiment was to evaluate the effect of organic fertilization on changes of chemical properties of a “Neossolo Flúvico Eutrófico” (Fluvent) and okra production, cultivated with and without mulching and irrigation depths. The experiment was installed in the Agroecology sector at Universidade Estadual da Paraíba. The treatments were designed in a randomized blocks using the 2 x 5 x 2 factorial, which corresponding to two irrigation depths (100 and 50% of the crop evapotranspiration - ETc), five doses of cattle manure to increase the level from 1.8 % to 2.8; 3.8; 4.8 and 5.8%, in soil with and without mulching (plant residues), with four replications, totaling 80 plots with 27 plants per plot. 140 days after planting okra, soil samples were collected at each plot and chemical analyses were performed. The okra production was evaluated based on the number of green fruits and crop yield. The data were submitted to analysis of variance. The application of cattle manures to the soil between 4.8 and 5.8% and irrigation with 100% of crop evapotranspiration - Etc, with and without mulching, was suitable for the cultivation of okra under semi-arid climatic conditions, which provided increases in the chemical attributes of a Fluvent and in the okra production.
