A seeder should place seed in an environment for reliable germination. The main objective of sowing is to put seeds at a desired depth and spacing within the row. Uniform seed distribution within the soil result in better germination and emergence and increase yield by minimizing competition between plants for available light, water, and nutrients. A number of factors affect seed distribution in soil. Seed metering system, seed delivery tube, furrow opener design, physical attributes of seed and soil conditions all play a part in determining seed distribution | SOYBEAN - MOLECULAR ASPECTS OF BREEDING Edited by Aleksandra Sudaric INTECHWEB.ORG Soybean - Molecular Aspects of Breeding Edited by Aleksandra Sudaric Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution 3.0 license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
