A influência da sementeira com e sem casca e de 4 compassos na densidade e no rendimento do amendoim - arachis hypogaea L.

Abstract

It was found that sowing with bark had a late and delayed emergence and significantly reduced plant density from emergence to harvest. On the other hand, sowing without bark showed an early and rapid emergence with significantly higher density and a high percentage of emergence. However, although the seedbed with bark had a slow and late germination and was the one that suffered the most action of the crows, affecting in some way the germination percentage and plant density, it resulted in more vigorous plants with a slightly greater growth than the seedless seedbed. In fact, despite the sowing with bark having significantly reduced the percentage of mortality and increased someone to match what was intended in terms of the increase in plant densities at harvest and in yields, as these, without the difference being significant, were lower than seedless seeding. As expected, higher plant densities during emergence and harvest were obtained with lower spacing between rows and between plants within rows, ie 45 cm of separation between rows and 10 cm have significantly led to higher pod yield per unit of area. As for the calipers, the 60 cmx 10 cm caliper significantly led not only to higher pod yield per hactare, but also seed yield per hactare in relation to the other tested pods. other The influence of sowing with and without bark and 4 bars on density and sowing with and without bark (Arachis hypogaea L.)
