Effect of green manure on quality of seeds of genotypes of beans.

Abstract

This study aimed to evaluate the physiological potential of seeds of 25 genotypes of beans grown in succession to potato crop with or without leguminous green manure. Trials were carried out in the experimental field and the seed analyses division of the agriculture department of the Universidade Federal de Lavras (DAGUFLA). Evaluations were performed using germination tests, accelerated aging, electrical conductivity, dry biomass, and seedling emergency. The factorial arrangements consisted in two levels of fertilization (with or without) and 25 beans genotypes (Ouro Negro from Black group; Emgopa 201 Ouro from Yellow group, plus the following: Carioca, Carioca-MG, BRSMG Talismã, Pérola, IAPAR-81, B-I, CII-78, CII-90, CII-103, CII-175, CII-244, CII-281, CII-337, CII-348, ESAL-693, ESAL-694, ESAL-695, ESAL-696, LH-2, LH-3, LH-10, and LH-11 from Mulatinho group). Greenmanure, residual and residual plus bean basis, differently influenced quality of seeds produced by the different genotypes. Green manure positively affected quality of seeds of the commercial genotypes Pérola, Emgopa 201Ouro, and Carioca.
