- The objective this work was to verify the effect of rows spaced and periods of sowing in
the autumn-winter season at seed physiological quality to various bean cultivars (Phaseolus vulgaris
L). The work was developed at the Experimental Farm of Faculdade de Engenharia de Ilha Solteira -
UNESP, located in the Selvíria (MS), county Brazil, with the objetive to verify the influence of two rows
spaced 0,45 and 0,60m apart in the first year (1995) and three rows spaced 0,30; 0,45 and 0,60m apart in
the second year (1996) and two periods of sowing (first may fortnight and first july fortnihgt) in the
behaviour of differents cultivars of de beans: Mineiro Precoce, Carioca, IAC Carioca, Carioca Mineiro,
IAC Carioca Pyatã, IAC Bico de Ouro, Ouro, IAPAR 14, IAPAR 16, IAPAR 31, IAPAR 57, IAPAR 65,
IAPAR 72 and ISA 1. The experimental desing used was the randomized blocks with four replications.
Each experimental plot was constituted by five rows with five meters long. The culture was conduted
under irrigation. The evaluations seed physilogical quality was developed at the Laboratory Technology
and Seed Analyse at Faculdade de Engenharia de Ilha Solteira - UNESP, following evaluations were
realized: germination and vigor test (first count, speed emergency index, accelerated aging and seedling
emergence). The results obtained allowed to conclude at sowing first may fortenight and the rows
spaced more strait (0,30 and 0,45cm) showed more adjusted for the seed yield high physiological quality.
