Küçük tohumların tek tane ekiminde tohum boyutu ve şeklinin yanı sıra, tohumların plaka deliklerine tutunma sürecinde ortaya çıkan elektriksel kuvvetin etkisiyle son derece önemli problemler yaşanabilmektedir. Bu sorunun üstesinden gelebilmek için küçük tohumlar genellikle ekilmeden önce kaplanmaktadır. Ancak kaplama işleminin maliyetli olmasından dolayı, küçük taneli tohumların kaplama yapılmaksızın, uygun işletme parametrelerinin seçimiyle ekilmesi bu çalışmanın amacını oluşturmuştur. Bu amaçla, farklı ilerleme hızlarında (0.5, 1.0 ve 1.5 m s-1) ve farklı ekim normlarında (0.67, 1.0 ve 2.0 kg ha-1) maş fasulyesi kullanılarak faktöriyel deneme deseni olarak dizayn edilen çalışmada, ekim ünitesinin performansı laboratuvar koşullarında değerlendirilmiştir. Çalışmanın sonuçlarına, sıra üzeri tohum dağılım düzgünlüğünün ekim normu ve ilerleme hızının artışından olumsuz etkilendiği ve ekim kalitesinin bozulduğu tespit edilmiştir. Bununla birlikte, ekim kalitesinin göstergesi olan kabul edilebilir tohum aralığı oranı değerleri, 0.5, 1.0 ve 1.5 m s-1 ilerleme hızlarında “ORTA”, 0.67 ve 1.0 kg ha-1 ekim normlarında “İYİ” ve 2.0 kg ha-1 ekim normunda “YETERSİZ” bulunmuştur. Tohum dağılımı düzgünlüğü açısından en iyi değerler ise 0.5 m s-1 ilerleme hızında ve 0.67 kg ha-1 ekim normunda elde edilmiştir. Bu sonuçlar, bin tohum ağırlığı 5 g olan maş fasulyesinin düşük ilerleme hızı ve ekim normlarında tek tane ekiminin yapılabileceğini göstermektedir.

Laboratory Scale of Planter Performance in Single Seed Planting of Mung Beans Without Coating

Öz

In single-seed planting of small seeds, extreme problems can arise due to the effects of seed size and shape, as well as the electrostatic forces generated during seed adhesion to plate holes. To overcome this issue, small seeds are usually coated before planting. However, due to the high cost of the coating process, this study aims to sow small-seeded crops without coating by selecting appropriate operating parameters. For this purpose, a factorial experimental design was applied using mung beans at different forward speeds (0.5, 1.0, and 1.5 m s-1) and planting rates (0.67, 1.0, and 2.0 kg ha-1) to evaluate the performance of the planting unit under laboratory conditions. The results showed that increasing the planting rate and forward speed negatively affected intra-row seed distribution uniformity, leading to a decline in planting quality. Furthermore, the quality of feed index, which indicates planting quality, was found to be "MODERATE" for 0.5, 1.0 ve 1.5 m s-1 forward speeds, "GOOD" at 0.67 and 1.0 kg ha-1 planting rates, and "INSUFFICIENT" at a planting rate of 2.0 kg ha-1. The best values for seed distribution uniformity were obtained at 0.5 m s-1 forward speed and 0.67 kg ha-1 planting rate. These results suggest that single-seed planting of mung beans, with a thousand-seed weight of 5 g, can be effectively performed at low forward speeds and planting rates without the need for seed coating.
