Furrow irrigation of peanuts

Abstract

A trial was carried out in Piracicaba, State of São Paulo, Brazil, during 1974, to evaluate the effect of furrow irrigation on the peanut (Arachis hypogaea L.) crop grown during late dry season. Six irrigations of 25.5 mm were made as needed, totalizing 153 mm. During the period of this study 161.3 mm of rainfall were registered. Weekly data were taken per plant of irrigated and non-irrigated plots, including: root dry weight, shoot dry weight and pod dry weight. Final data were taken on number of plants per meter of row and yield. The following conclusion could be drawn from this experiment: late planting allowed longer vegetation period than the usual; irrigated plants had better development than the non-irrigated; irrigation improved yield per hectare but not per plant.
