19-34 INFLUENȚA ELEMENTELOR CONSTRUCTIVE ALE MAȘINILOR DE SEMĂNAT ASUPRA UNIFORMITĂȚII DE DISTRIBUȚIE A SEMINȚELOR LA CULTURILE TRIFOLIENE

THE INFLUENCE OF CONSTRUCTIVE ELEMENTS
OF SEEDING MACHINES OVER SEED DISTRIBUTION
ON TRIFOLIENUM CROPS
The paper investigates the influence of different constructive elements
concerning the sowing process of seeding machines, over the distribution
uniformity of small seed crops with emphasis on trifolienum crops. For this
purpose, the paper will analyze the interdependence between the constructive
parameters of the elements involved in the distribution flow respectively, seed
box, metering device, seed transport tubes, furrow openers, and seed
distribution uniformity.

21-28 O METODĂ DE EVALUARE A UNIFORMITĂŢII DE DISTRIBUŢIE A SEMINŢELOR CULTURILOR TRIFOLIENE

A METHOD FOR EVALUATING SEED DISTRIBUTION
UNIFORMITY OF TRIFOLIUM CROPS
A method is presented for evaluation of small seeds distribution
uniformity under laboratory conditions. The advantage of this method consists
in a morequicker evaluation of seed distribution uniformity using computer
aided techniques. The program developed in a computational program
determines the number of seeds sown on a surface by converting an image
taken from the sown surface to a binary numeral system by specific
mathematical formula inputted into the program.
