Effects of various strip widths and tractor forward speeds in strip tillage on soil physical properties and yield of silage corn

Bu çalısmada, farklı serit genisliklerinin silajlık mısırda tarla filizi çıkısı, bitki gelisimi ve silaj verimine olan etkilerinin belirlenmesi amacıyla tarla kosullarında 2 yıllık bir deneme yürütülmüstür. Seritsel toprak isleme için, bu amaca uygun hale getirilen C tipi bıçaklara sahip bir frezeli ara çapa makinasından yararlanılmıstır. Frezeli ara çapa makinası bıçaklarının flans bağlantı konumları değistirilerek elde edilen 22.5, 30 ve 37.5 cm genisliklerindeki seritlerle tarla yüzeyinin sırasıyla % 30, 40 ve 50’si islenmistir. Farklı toprak parçalama değerleri elde etmek için 370 $min^{ -1}$ sabit r otor dönme hızı ve 10 cm is derinliğinde kullanılan frezeli ara çapa makinası ile 1.8, 3.6 ve 5.4 km $h^{ -1}$’ten olusan 3 farklı traktör ilerleme hızında çalısılmıstır. Ekim, hassas ekim makinası kullanılarak 70 cm sıra aralığında yapılmıstır. Elde edilen sonuçlara göre, serit genisliğinin artısı toprak sıcaklığını arttırırken, buharlasmayı hızlandırdığından dolayı, toprak nem içeriğinin azalmasına neden olmustur. Tarla filizi çıkısı, bitki boyu ve silaj verimi serit genisliğinin artmasıyla artarken, ortalama çıkıs süresi serit genisliği artısı ile azalmıstır. Traktör ilerleme hızı toprağın parçalanması üzerinde etkili olmustur. Đlerleme hızı arttıkça, küçük toprak parçacıklarının dağılımında azalma meydana gelmistir. Traktör ilerleme hızının diğer parametreler üzerinde istatistiksel olarak önemli bir etkiye sahip olmadığı ortaya çıkmıstır.

Seritsel toprak islemede farklı serit genisliklerinin ve Traktör ilerleme hızlarının toprak fiziksel özellikleri ve silajlık mısır verimine etkileri

In this study, a 2 year experiment was conducted in field conditions in order to determine the effects of various strip widths on seedling emergence, plant growth and yield of silage corn. A row crop rotary hoe with C type blades, which was equipped for this purpose, was used for strip tillage. In the experiment, 30%, 40% and 50% of the field area was tilled respectively with the strips in 22.5, 30 and 37.5 cm widths, which were obtained by changing the positions of flanges and blade connections of the rotary hoe. The rotary hoe, which was used with a constant rotor rotation speed of 370 $min^{ -1}$ and a tillage depth of 10 cm, was operated at 3 different tractor forward speeds such as 1.8, 3.6 and 5.4 km $h^{ -1}$ in order to get various soil fragmentation values. The seeds were sown by using precision seed planter at 70 cm row intervals. According to the results obtained from the study, since increasing the strip width also increased the soil temperature and accelerated the evaporation, it resulted in a reduction of the soil moisture content. While seedling emergence, plant height and the silage yield increased with the increase of the strip width, the average emergence time decreased. Tractor forward speed had an effect on soil fragmentation. When the tractor forward speed increased, there seemed to be a reduction in the breaking of soil particles. It was found that the tractor forward speed did not have a statistically significant effect on other parameters.
