Abstract

Abstract: The aim of this study was to quantify the longitudinal distribution of plants in the row and seed depth and their effects on hypocotyl length and diameter and on yield components and grain yield of common bean, specifically the cultivar BRSMG Realce in a Latossolo soil in the Cerrado (Brazilian tropical savanna). The data on plant distances in the row were obtained in the field with the aid of a measuring tape in four rows of 2.5 m length. Seed depth was determined by measuring the length of the hypocotyl that was within the soil after pulling up the plant. Hypocotyl diameter was evaluated at ground level using a digital caliper. Descriptive (univariate) statistical analysis was applied to the data. Linear correlations were established among distribution of distance between plants in the row, the depth of sowing, the characteristics of the hypocotyls, and grain yield data of common bean. Negative linear regression was observed between grain yield with sowing depth, and positive linear regression between hypocotyl diameter and longitudinal spacing between plants in the row. In the sowing process, special attention should be given to seed distribution in the row to avoid subsequent uneven plant distribution and to seed depth to avoid yield loss.

Summary

Introduction

Dry edible bean or common bean (Phaseolus vulgaris) is a crop of considerable economic and social importance in many countries and one of the main sources of plant protein in the human diet. Even at adequate densities, the sowing process can bring about bad seed distribution in the row and seed placement at depths greater than planned. In any crop, sowing depth and seed distribution in the row should be adequate to ensure seed germination and seedling emergence and development (Martins et al, 1999; Rodrigues et al, 2016). According to Cortez et al (2006), all plant spacings from 0.5 to 1.5 times the mean spacing (MS) expected is considered acceptable. Values outside this limit are considered missing plants (more than 1.5 times the MS) or multiple plants (less than 0.5 times the MS)
