Phosphate Fertilization in Amaranth Culture cv. BRS Alegria in Second Harvest in the Cerrado

Abstract

Vegetable species, capable of diversifying production in the second crop of the Cerrado, producing grains rich in protein and providing dry matter for off-season, are most welcome. The amaranth presents these characteristics, however its cultivation is little known in Brazil. The adequate availability of nutrients for this plant, under cerrado conditions, has not yet been defined and these soils, in turn, are of low natural fertility, deficient, mainly, in phosphorus. Before this senary, the present work was developed with the objective of evaluating agronomic and productive aspects of amaranth cv. BRS Alegria, cultivated in succession to soybean, underwent increasing doses of Pittelkow et al.; JEAI, 39(4): 1-9, 2019; Article no.JEAI.49828 Original Research Article
