Physical Properties of Maize Seed and its Effect on Sowing Quality and Variable Distance of Individual Plants

Abstract

Precision sowing has been a major thrust of agricultural engineering research for many years; however, most of the research and development work has dealt with seeders for agronomic crops. Sowing quality means required vertical (depth) and horizontal (spatial) spacing of seeds in the soil with minimal damage to the seeds. The spatial distribution of seeds (horizontal spacing) is given by distance between the rows and spacing of the seeds in a row. The objective of the study was the evaluation and comparison of the sowing quality of sowing machine JD MaxEmerge XP with mechanical filling of ladle holes with holding fingers within usage of seeds with different dimensional and shape attributes in agricultural conditions. As it was observed that shape attributes have a significant effect on seeding quality and at the end it affects emergency and whole further growth of maize seeds. Sowing machine JD MaxEmerge XP reached good results for the quality especially when using the angular seeds. It reached the sowing quality expressed by the standard deviation of 46.95 -50.76 % when seeds PR 37 N01 and for seeds PR 37 N01 it is 47.43 -48.73 %. Another evaluative criterion is dual sowing of seeds or plants (DRR), it was reached the average value 3.65 -2.45 % for angular seeds and the average of 1.54 -3.71 % for approximately spherical seeds.

Evaluation of Physical Properties of Maize and Pigeonpea Seeds for Seed Metering Mechanism

“…To ensure free flow of seeds, the slope of the seed hopper is taken higher than the average angle of repose of seeds [8]. Physical properties and shape attributes have a significant effect on seeding quality and at the end it affects seed emergence and whole further growth of seeds [9].…”

Physical characterization of morphologically diverse colour maize (Zea mays) seeds

“…The shape of biological material determines its cooling and heat taking capacity. The shape such as angular or circular seeds also decides its mobility on the conveyer belt or in running water channel (Findura et al 2018). The sphericity ranged from 0.26 to 0.40 mm among the studied landraces but the exotic accession EC 1008287 had the highest sphericity value of 0.40 mm.…”
