“…The recommendation of the appropriate amount of biomass mixture of these two spontaneous species must be based on the knowledge obtained in experiments where the effects of different quantities of these green manures during different years on the production and the components of these vegetables were tested. The response obtained can be adjusted by various statistical models seeking to estimate the optimum amount of the mixture of these green manures (BEZERRA NETO et al, 2014;SILVA et al, 2018b). It is known, however, that adjustment of polynomial and exponential models in research with fertilizers is greatly affected by the model used, coefficient of variation, location of the maximum point, and clustering of experiments (ZIMMERMANN; CONAGIN, 1986).…”

The broadleaf vegetables require large amounts of nutrients to provide a high productivity, and quality products, mainly due to their short period of development and growth. The green manuring has emerged as a viable alternative to provide these requirements for these vegetables, mainly from spontaneous species in the Caatinga biome. Thus, the aim of this study was to evaluate and estimate the maximum physical and economic efficiencies of lettuce and arugula agro-economic characteristics in monocropping as a function of equitable quantities of Merremia aegyptia and Calotropis procera biomass mixtures at different growing seasons, using polynomial and exponential models, based on the criteria of biological logic of growth and production of the cultures, of significance of the regression mean square, of high value of the coefficient of determination (R2), of significance of the regression parameters, and of maximization of productivity and profit. The types of polynomial and exponential models chosen estimated the lettuce and arugula agro-economic characteristics with good precision and high R2 values. The maximum agronomic (physical) efficiency of the lettuce and arugula was made possible with the incorporation into the soil of 47.38 and 42.23 t ha-1 of M. aegyptia and C. procera, respectively, and the maximum economic efficiency of production for these leafy vegetables was reached with biomass amounts of 45.96 and 33.61 t ha-1, respectively. The rates of return obtained for lettuce and arugula cultivation for the optimized mixture amounts were 2.6 and 1.5 of those achieved in the control treatment (without fertilization), respectively.

“…The Silk flower (Calotropis procera (Aiton) W. T. Aiton) is an exotic species belonging to the Asclepiadaceae family, with high adaptability to semiarid conditions, where it is considered as biological invasive by some authors (FABRICANTE et al, 2013). It serves as a forage contribution to the herds (FERREIRA et al, 2015;ALMEIDA et al, 2017) and provides increased consumption and weight gain for animals (SILVA et al, 2010). Moreover, it is a plant that has high exploitation potential as green manure due to its high biomass production and the high concentrations of N, P, K in its tissues (SILVA et al, 2018;MEDEIROS et al, 2019).…”

Several abiotic factors may influence the growth and development of forest species. Among these, luminosity is one of the most important, because it affects plant physiological processes and control their metabolism. The objective of this study was to evaluate the effect of different shading levels under growth and chlorophyll indices on Calotropis procera plants. The experiment was conducted in a greenhouse in a completely randomized design with 5 treatments (0, 30, 50, 70 and 90% of shading), 8 replicates and one plant per plot. Growth characteristics (leaf area, leaf area index, specific leaf area, leaf area ratio and leaf specific weight) and chlorophyll a, b, total index and chlorophyll a/b ratio were evaluated. The data were submitted to analysis of variance by the F test and in the cases of significance a linear and polynomial regression analysis was performed. Shade levels in the 40% range provide higher leaf area and leaf area index in silk flower plants. The specific leaf area and the leaf area ratio are positively influenced by shading. In shaded environments silk flower plants have reduced chlorophyll indices.

The use of spontaneous species from the Caatinga biome as green manure is a promising practice in increasing the productivity of agricultural systems and sustainable exploitation of the environment. This study aimed to estimate the maximum physical and economic efficiencies of radish agroeconomic characteristics in monocropping as a function of roostertree (Calotropis procera (Ait.) R. Br) biomass amounts in two cropping seasons in a semi-arid environment. The experimental design was randomized complete blocks with five treatments and five replications. The treatments consisted of different roostertree biomass amounts: 16, 29, 42, 55, and 68 t ha-1 on a dry basis, incorporated into the soil. In each block, two additional treatments were added, one without fertilization (control) and the other with mineral fertilizer, for comparison purposes with the maximum efficiency treatment. The radish cultivar planted was ‘Crimson Gigante’. The fertilization of the radish to obtain the maximum optimized productive efficiency (9.56 t ha-1) was possible with the incorporation of 50.86 t ha-1 of C. procera dry biomass into the soil. The maximum optimized agroeconomic efficiency (based on a net income of 37,641.08 R$ ha-1) of radish cultivation was obtained with 44.39 t ha-1 of C. procera dry biomass added to the soil. The rate of return and the profit margin obtained were 2.94 R$ for each real invested, with a profit margin of 62.55%. The use of biomass from the C. procera green manure is a viable technology for producers who practice radish monoculture in a semi-arid environment.
