Efeito do composto de resíduos orgânicos no rendimento do feijão nhemba -vigna unguiculata L variedade erecta INIA 36 B

Abstract

The compost of organic matter, due to its action as a conditioner of the physical, chemical and biological properties of the soil, constitutes an important organic fertilizer. The present work was carried out at FAEF from March to May 2006. The experiment aimed to evaluate the effect of the use of compost (produced from the remains of various crops and cattle manure) on soil fertility on bean yield nhemba (Variety INIA 36 B) in terms of pod number, pod weight and seed weight per treatment. The experiment used a completely randomized block design, with 4 replications, which corresponded to the application of 0, 2, 4, 6, 10 ton/ha. The data obtained were submitted to analysis of variance and Scott-Knott test at 5% probability using the SAEG statistical package. From the analysis performed, there is evidence that shows statistically significant effects in the seed weight variable between the 10 and 6 t/ha treatments in relation to the others, at the significance level of 5% probability. As for the variable pod weight, there were only significant differences between the control treatment (0 t/ha) and the others (2, 4, 6 and 10 t/ha). Taking into account the data analyzed, the best option corresponds to the treatment with 6 t/ha of compost, partly because it presents yields very close to the 10 t/ha treatment and because the treatment with 10 t/ha requires more amount of compost to obtain a yield almost equal to that of 6 t/ha. Statistically there were no significant differences between treatments in plant yield in terms of number of pods.
