Conteúdo: |
Phosphorus (P) deficiency is one of the most yield limiting factors in crop production in Brazil ian Oxisols. A greenhouse experiment was conducted to evaluate upland rice genotypes at low (25 mg P kg-1) and high (200 mg P kg-1) P levels applied to a Brazilian Oxisol. Grain yield and yield components were significantly influenced by P level and genotype treatments. There was a significant interaction between P level and genotype treatments in relation to grain yield, indicating genotypes responded differently under two P levels. Based on grain yield efficiency index (GYEI), genotypes were classified into efficient, moderately efficient and inefficient groups. The efficient genotypes in utilizing P were 'BRA052053', 'BRS Primavera', 'BRA052015', 'BRA052023', 'BRA01506', 'BRA052045', 'BRA032033', 'BRA01596' and 'BRA052034'. Remaining genotypes were classified as moderately efficient in P use efficiency. None of the genotypes were fall into inefficient group. Grain yield was significantly and positively related with shoot dry weight, panicle number, grain harvest index, 1000-grain weight and had a negative and significant correlation with spikelet sterility. Grain weight was having maximum contribution in total rice plant weight comparing to root and shoot, indicating improvement in harvest index of modern Brazilian upland rice cultivars by breeding. |
