Abstract

The use of cattle manure and other organic compounds can be a profitable and efficient alternative in sustainable agriculture. The aim of this work was to evaluate the development and production of sesame ‘BRS Seda’ for organic fertilization at different doses, under the conditions of soil and climate found in Catolé do Rocha, in the State of Paraíba, Brazil. The following characteristics were evaluated: number of leaves and pods; plant height; stem diameter; number of flowers; dry weight of the leaves, stems, roots, pods and seeds; number and length of secondary branches; height of the first fruit; seeds per pod; pod length; and emergence percentage and speed of the produced seedlings. The different doses of cattle manure influenced pod length, number of seeds per pod, and emergence percentage and speed of the produced seedlings, with better results for the dose of 40 t ha-1.   Key words: Sesamum indicum L., fertilization, morpho-agronomic characterization, organic production.

Highlights

  • Sesame (Sesamum indicum L.) shows great adaptation to the conditions of soil and climate of the northeastern region of Brazil, which generally presents good yield even under irregular and scarce rainfall observed in this region (Pereira et al, 2017)

  • The aim of this work was to evaluate the development and production of sesame ‘BRS Seda’ for organic fertilization at different doses, under the conditions of soil and climate found in Catolé do Rocha, in the State of Paraíba, Brazil

  • These authors studied the effects of cattle manure (0 to 60 t ha-1) fertilization in sesame ‘BRS Seda’ cultivar under rainfed conditions and reported that seed vigor was positively influenced by cattle manure application in the soil

Summary

Introduction

Sesame (Sesamum indicum L.) shows great adaptation to the conditions of soil and climate of the northeastern region of Brazil, which generally presents good yield even under irregular and scarce rainfall observed in this region (Pereira et al, 2017). This crop develops well when there is an adequate supply of nutrients in the soil; it is essential to provide the correct fertilizer for each planting situation. These authors studied the effects of cattle manure (0 to 60 t ha-1) fertilization in sesame ‘BRS Seda’ cultivar under rainfed conditions and reported that seed vigor was positively influenced by cattle manure application in the soil
