- ARRANJOS ESPACIAIS PARA A CULTURA DO FEIJOEIRO EM SISTEMA DE SEMEADURA CONVENCIONAL José Antonio SCHAMNE Pedro RONZELLI JÚNIOR Edelclaiton DAROS Henrique Soares KOEHLER Agrociencias yield row width population morphology Phaseolus vulgaris A field trial was carried out at Cangüiri Experimental Station of The Universidade Federal do Paraná from January, 13th till April, 18th 2000. The objective was to determine the most adequated spatial arrangement for dry beans in conventional crop system. The variety used was 'FT Bionobre'. The experimental design was a randomized complete block, with four treatments (0.30 m, 0.40 m, 0.50 m and 0.60 m row width) arranged in strips and six replications. There were evaluated: yield, grain weight, seeds per pod and apparent harvest index. In order to evaluate the morphological characteristics, a randomized complete block for width row, with developmental stages V4, R6, R7, R8 and R9 split plot on it, was used. Plots were formed by ten rows with 5.0 m length. Populations were standardized by thinning in the four width rows, in which remained about 8.1; 10.8; 13.5; and 16.2 plants.m-1. Tendency of leaf area increasing and apparent harvest index decreasing was observed when row width was increased. Greater leaf area associated with low water availability can have contributed to diminish the yield. Yield in 0.30 m row width was greater yield in 0.60 m. 2001 artículo científico 1519-1125 https://www.redalyc.org/articulo.oa?id=99517443014 pt http://www.redalyc.org/revista.oa?id=995 Scientia Agraria application/pdf Universidade Federal do Paraná Scientia Agraria (Brasil) Num.1-2 Vol.2
