Organic fertilization to increase the productivity of the lima beans (Phaseolus lunatus L.)

Abstract

The present work had as objective to evaluate the yield of two varieties of fava in function of application of organic compost and dairy waste. The experiment was carried out at the Experimental Farm belonging to the Federal Rural University of Pernambuco (UFRPE). The experiment was carried out in a randomized block design in a factorial scheme [(2x3) + 4], with two varieties of Lima bean, three forms of organic fertilization plus four additional controls, in three repetitions. Data were subjected to analysis of variance and treatment means, compared by the Tukey test (P <0.05). Dunnett's test was also used for comparisons involving additional witnesses and other treatments. The software used for statistical analysis was SAEG 9.1 and SAS 9.0. Dairy waste was the fertilizer that most contributed to the increase in productivity, making it suitable for use as fertilizer. The Branquinha variety is indicated for production, because it responded better to the types of fertilizers used.
