Diyarbakır koşullarında farklı tatlı sorgum çeşitlerinin biyokütle verimi ve silaj kalite özelliklerinin belirlenmesi

Öz

Bu araştırma, Diyarbakır koşullarında bazı tatlı sorgum (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) çeşitlerinin biyokütle verimi ile silaj kalite özelliklerini belirlemek amacıyla yürütülmüştür. Hasat, bitkinin salkımdaki tanelerin süt-hamur olum döneminde yapılmıştır. Araştırmada çeşitlere bağlı olarak, bitki boyunun 326.1-373.7 cm, sap kalınlığının 19.20-21.43 mm, bitkideki yaprak sayısının 13.55-14.40 adet, yaş ot (hasıl) veriminin 8785.7-11635.7 kg da-1 ve kuru madde veriminin 2698.6-3496.5 kg da-1 arasında değiştiği saptanmıştır. Ayrıca önemli silaj kalite özelliklerinde pH değeri 4.18-4.59, HP oran %2.06-2.91, ham kül içeriği %7.55-9.43, ham selüloz oranı %24.40-31.04, nişasta içeriği %7.46-10.70, NDF %47.23-59.33, ADF içeriği %29.96-39.05, ADP oranı %0.38-0.86, sindirilebilir kuru madde oranı %58.74-65.76, kuru madde tüketimi %2.05-2.54, nispi yem değeri 94.1-129.6, net enerji laktasyon içeriği 1.34-1.46 Mkal kg-1, Mg %0.27-0.36, Ca %1.09-1.20 ve P içeriği %0.19-0.21 arasında değişim göstermiştir. Sonuç olarak araştırma sonuçlarımız No91, M81E ve Topper-76 sorgum çeşitlerinin kuru madde verimi açısından, Roma ve Ramada çeşitlerinin ise silaj kalite özellikleri bakımından ilk sıralarda yer aldığını göstermiştir.

Determination of biomass yield and silage quality characteristics of different sweet sorghum varieties in Diyarbakır condition

Öz

This research was carried out to determine the biomass yield and silage quality characteristics of certain sweet sorghum (Sorghum bicolor var. saccharatum (L.) Mohlenbr.) varieties in Diyarbakır conditions. Plant material was harvested during the milk-dough maturation period of the grains in the panicle of the plant. In the research, although it varies depending on the varieties, the plant height was 326.1-373.7 cm, the stem thickness was 19.20-21.43 mm, the number of leaves was 13.55-14.40 number plant-1, the biomass yield was 8785.7-11635.7 kg da-1 and the dry matter yield was 2698.6-3496.5 kg da-1. In addition, it was determined that pH varied between 4.18 and 4.59, CP content between 2.06 and 2.91%, crude ash between 7.55 and 9.43%, crude fiber between 24.40 and 31.04%, starch content between 7.46 and 10.70%, NDF between 47.23 and 59.33%, ADF between 29.96 and 39.05%, ADP between 0.38 and 0.86%, digestible dry matter ratio between 58.74 and 65.76%, dry matter intake between 2.05 and 2.54%, relative feed value between 94.1 and 129.6, and net energy lactation between 1.34 and 1.46 Mcal kg-1, Mg between 0.27 and 0.36%, Ca between 1.09 and 1.20% and P between 0.19 and 0.21%. In conclusion, our results showed that the No91, M81E, and Topper-76 sorghum varieties stood out in terms of dry matter yield, while the Roma and Ramada varieties ranked highest in terms of silage quality characteristics.
