Performance of roquette fertilized with cattle and green manure using two planting densities

Abstract

This research was conducted to study the direct fertilization combining 0 and 160 kg N ha-1 of cattle manure and green manure using two population densities and its residual effect on roquette culture of (Eruca sativa) in Seropédica City, Rio de Janeiro State, on yield, leaf area index, number of leaves plant-1, total fresh weight, leaves dry matter, roots dry matter, stems dry matter, total dry matter and stems height. The experimental design was randomized blocks in factorial design 2 x 2 x 2 and three replicates: 0 and 160 kg N ha-1 of cattle manure, 0 and 160 kg N ha-1 of shoot of pigeon pea and 500,000 and 1,000,000 plants ha-1. The results indicate that the population density of 500,000 plants ha-1 showed, in general, better results in terms of yield per plant. However, 1,000,000 plants ha-1 had significantly higher yield per land area.. It was observed that fertilization had direct effect on yield, total fresh weight, leaves dry matter, stems dry matter, total dry matter, number of leaves plant-1 and stems height, while its residual effect showed response on roots dry matter and stems dry matter.
