EFFECT OF DIFFERENT SOWING DATES ON THE GRAIN YIELD AND SOME YIELD CHARACTERISTICS OF TEFF [Eragrostis teff (Zucc.) Trotter]

Abstract

This research was carried out to determine the potential of teff as a staple crop for the Mediterranean climate during 2015 and 2016. The effects of four different sowing dates (15 April, 15 May, 15 June and 15 July) on the grain yield and some yield characteristics were investigated. The teff genotype "Dessie" was used as plant material and plant height, thousand-grain weight, harvest index and grain yield were tested. Two-year average results indicated that there were significant differences in mentioned characteristics among the sowing dates. Delayed sowing dates reduced the grain yield. The highest total grain yield, 2780 kg ha -1 , was obtained for the teff seeds sown on the 15 th April under Mediterranean ecological conditions.

Evaluation of some forage pea (Pisum arvense L.) lines and cultivars in terms of herbage yield and quality

“…In previous studies, herbage and hay yields were reported respectively as between 884-5275 kg da -1 and between 189-960 kg da -1 (Timuragaoglu et al, 2004;Sayar and Anlarsal, 2008;Sayar et al, 2009;Geren and Alan, 2012). Present findings were slightly lower than earlier findings since previous genotypes were sown in winter.…”

Effects of different cutting height and nitrogen levels on the forage yield and quality of giant kinggrass (Pennisetum hybridum)

“…Dev kralotu bitkisi üzerinde üç farklı biçim yüksekliğini (5, 10, 15 cm) test eden Paulino et al (2007), HP oranlarının biçim yüksekliğinden etkilenmediğini vurgulamıştır. Buna karşılık, Miscanthus x giganteus'da farklı biçim yüksekliğinin (0, 5, 10, 15, 20 cm) silaj HP oranı üzerinde önemli etkisini bildiren Geren et al (2019), 0 cm'den 20 cm'ye doğru artan anız yüksekliği karşısında HP oranlarının sırasıyla %6.6, 7.0, 7.5, 8.5 ve 9.6'ya yükseldiğini ifade etmişlerdir. Öte yandan, çok yıllık buğdaygillerde uygulanan biçim işlemleri sonucunda toprak yüzeyinde bırakılan anız miktarı ne kadar fazlaysa yaprak oranının da arttığını, sert yapılı, selülozca zengin sap oranı ne kadar az ise yemin HP oranının yükseldiğini ifade eden araştırıcılar, bulgularımızı desteklemektedir (Ishii et al, 1995;Can vd., 2003;Kuşvuran & Tansı, 2003).…”
