| In Northeastern Brazil, the sweet potato is cultivated in small farms, in a family farming systems, constituting themselves an alternative way for the generation of food, employment and income. This study aimed to assess the effect of cattle manure levels and biofertilizer concentrations on the sweet potato cultivar White Queen productivity. The experiment was carried out from March to September 2007 at the EMEPA Experimental Station in Lagoa Seca, Brazil. The experimental design was randomized blocks, in split split plot 6 x 4 x 2 + 1 scheme, with four replications. The plots consisted of cattle manure levels (0, 10, 20, 30, 40 and 50 t ha-1), the subplot of biofertilizer concentrations (0, 15, 30 and 45%) and the sub subplots consisted of methods of... |

| Yellow passion fruit, because it is sensitive to the salinity of irrigation water or soil, requires restrictive water management strategies and inputs that mitigate the effects of salts on plants irrigated with harmful saline water levels. As such, an experiment was designed to evaluate the effects of bovine biofertilizer and mineral fertilization with NPK on the growth and production of yellow passion fruit plants irrigated with moderately saline water. Treatments were arranged in a randomized block with three replications and 12 plants per plot using a 4×2 factorial design with four doses of bovine biofertilizer diluted in water at 0, 33.3, 66.6 and 100% proportions in soil with and without NPK. The evaluated variables included the stem diameter, number... |
