Objetivou-se, com este trabalho, avaliar o efeito da salinidade água de irrigação no feijão-caupi e identificar genótipos tolerantes ao estresse salino nos estádios iniciais do seu desenvolvimento. Os níveis condutividade elétrica foram: 0; 2,5; 5,0 7,5 dS m-1. A tolerância foi avaliada através redução relativa matéria seca parte aérea cada genótipo. resultados foram comparados analisados pelo teste Scott-Knott, a 0,05 probabilidade. Todas as variáveis afetadas aumento irrigação. O genótipo...
ABSTRACT Genotypes can respond differently to environments; thus, studies on adaptability and production stability are important assist breeders in the identification recommendation of cultivars. The objective this work was determine cowpea genotypes focused subsidize recommendations cultivars for green grain state Ceará, Brazil. Five assays were conducted different locations two climatic regions Ceará: a tropical mild hot semiarid region encompassing municipalities Acaraú, Pentecoste,...
ABSTRACT The precocity of cowpea is important because it indicates the possibility increasing and/or stabilizing production in regions with long periods drought. aim this study was to evaluate genetic variability and select extra-early progenies. Fifteen F3:6 progenies were evaluated 2014 while sixty-two F7 2015. Two commercial cultivars used experiments performed irrigated perimeter Baixo Acaraú, Marco, CE. following characteristics evaluated: number days for flowering (NDF), maturity...
ABSTRACT Landraces are sources of genetic variability, especially with respect to alleles that confer tolerance biotic and abiotic factors and, therefore, can aid breeding programs in the development promising cultivars. However, it is necessary know this patrimony at a level allows its alleged use programs. In sense, objective study was: (i) identify cowpea landraces present agronomic potential (ii) evaluate diversity for future cross-breeding. For this, two trials (coastal sertão state...
Widely grown in diverse regions of Brazil, cowpea has high nutritional value, is easily cultivated, and can fix nitrogen (N) symbiotically. Although there are commercial inoculants for cowpea, it difficult small producers to acquire them. A nodule preparation an inexpensive prepared option farmers. The aim this study was test a as low-cost inoculant, increasing seed grain production. Thus, different cultivars were compared two locations, the municipalities Crato Madalena, both...
Intercropping is a method of growing plants that assists in rational use natural resources. Based on this concept, the aim study was to evaluate response collard green and radish ‘Cometo’ crops monoculture intercropping under different spatial arrangements through physical production indicators (technical coefficients). The conducted plant beds randomized block design (RBD) with 5 treatments 4 replications. involved two separately intercropped arrangements: (1:2) one row between rows green;...
