This study aimed to evaluate the yield and the quality of the fruits of two okra cultivars (Abelmoschus esculentus), due to the varying doses and types of biofertilizers. The experiment was conducted the period September to December of 2017, at the experimental Piroás Farm, in the city of Redenção-CE, Brazil. The experimental design used was entirely randomized, in factorial design 5 × 2 × 2, referring to the five doses of the biofertilizer (0, 0.5, 1, 1.5 and 2.0 L plant-1 week-1), versus two types of liquid biofertilizers (bovine and caprine under aerobic fermentation) and two okra cultivars: Santa Cruz 47 and Clemson Spineless. The number of the fruits per plant, the average mass of the fruits, yield, the length and diameter of the fruit and peel thickness of the okra fruit, were increased according to the increase on the biofertilizers doses. The cultivar “Santa Cruz 47” presented higher values in the length of the fruit, whereas the cultivar “Clemson Americano 80” was superior in the variables “average fruit mass” and “diameter of the fruits”.

Objetivou-se avaliar a influência da salinidade da água de irrigação e da cobertura vegetal morta no crescimento inicial da cultura do milho. O experimento foi conduzido no período de setembro a outubro de 2017 na Fazenda Experimental Piroás, da Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), Redenção-CE. O delineamento experimental foi inteiramente casualizado (DIC) em esquema fatorial 5 x 2, correspondendo a cinco níveis de salinidade da água de irrigação (1,0; 2,0; 3,0; 4,0 e 5,0 dS m -1 ) versus dois tipos de cobertura (presença e ausência de cobertura vegetal morta), com 5 repetições. As variáveis analisadas foram o número de folhas, a altura de planta, o diâmetro do caule, a área foliar, o comprimento da raiz, a massa seca da parte aérea, a massa seca da raiz e a massa seca total. O uso da cobertura vegetal morta exerce efeito atenuador, promovendo aumento no comprimento de raiz e possibilita maior número de folhas de plantas de milho irrigadas com água de baixa e alta salinidade. A altura de planta, a área foliar e o diâmetro do caule reduziram quando as plantas de milho foram irrigadas com água salina. A salinidade da água de irrigação afeta a produção da massa seca da parte aérea, a massa seca da raiz e a massa seca total das plantas de milho.

Shading Screens and mulching may provide a favorable environment for radish growing in regions of adverse climates. This work aimed to evaluate the radish productivity under the influence of different shading screens associated with the presence and absence of mulch in two different years. The experiment was carried out in two different seasons (2017 dry season and 2018 rainy season), in the vegetable garden of Liberdade campus, at the University of International Integration of Afro-Brazilian Lusophony (Unilab), municipality of Redenção-CE. The experimental design was in randomized blocks in a split-plot arrangement, with four repetitions, in which the plots consisted of growing with and without mulching and in the subplots, five shading screens: 50% Black Shading Screen (50% BSS), 50% Red Shading Screen (50% RSS), 30% White Shading Screen (30% WSS), 70% Black Shading Screen (70% BSS) ), and full sunlight (FS). The red shading screens 50% and white 30%, in addition to cultivation under full sunlight, provide higher performance in terms of the number of leaves, tuberous root diameter, tuberous root matter, and the radish crop productivity, regardless of the evaluated period. The applied mulch does not influence the productivity of the rabante, influencing only the gain of dry mass of the aerial part, soluble solids and length of the tuberous root.
