Yield of ‘Pingo de Ouro’ Cowpea Bean Under Different Sowing Densities and Goat Manure Doses in the Region of Mossoró, Brazil

Abstract

Using goat manure may substantially increase cowpea bean productivity. This study evaluated the yield of ‘pingo de ouro’ cowpea bean under different sowing densities and goat doses in the region of Mossoró, Brazil. The experiment was conducted from October to December 2016 at the Experimental Farm Rafael Fernandes, Mossoró-RN, Brazil. Treatments arranged in two-way factorial with four goat manure doses (0.0, 0.5, 1 and 2 kg m-1), and two sowing densities of bean (75,000 and 37,500 plants ha-1), with three replicates. The experiment was performed in complete randomized blocks design. We evaluated the number and length of pods per plant, number of seed per pod, weight of 100 dry grains and dry grain yield. Higher grain yield occurred using 2.0 kg m-1 of goat manure (1,162.4 kg ha-1 or 234 kg 2,000 m-2) and 75,000 plants ha-1 (693.4 kg ha-1 or 138.6 kg 2,000 m-2). High sowing density in combination with goat manure is an affective.

Effect of Plant Density on Yield and Yield Components of Cowpea (Vigna unguiculata L.) in the Semi Arid Region of Brazil

“…[14], evaluating cowpea production depending on the use of inoculant and organic and mineral fertilizers, found a number of pod -1 grains of 14.3 units with biofertilizer application, which is lower than the aforementioned research. [15] evaluating yield of Pingo de Ouro cowpea bean under different sowing densities and goat manure doses in the region of Mossoró, Brazil, with a number of seeds worth 12.0 pod units -1 , was lower than the density of 35,714 plants ha -1 .…”
