MORPHOLOGICAL CHARACTERISTICS AND SEED YIELD OF EAST ANATOLIAN LOCAL FORAGE PEA (Pisum sativum ssp. arvense L.) ECOTYPES

Mustafa TAN, Ali KOC , Zeynep DUMLU GUL

Abstract

Local forage pea ecotypes, (Pisum sativum sp. arvense L.) have been cultivated by farmers in the Northern part of the Eastern Anatolia region of Turkey for years and there has not been any breeding regarding these materials up to now. Thus, the material shows great variation with respect to morphological and agronomical characters compared to commercial forage pea cultivars. The objective of this study was to evaluate yield and some traits of promised local pea ecotypes which were selected previous year’s screening study material collected from 61 different locations in the northern part of the Eastern Anatolia in 2007. All seed materials were sown with randomized complete blocks design with three replicates in Atatürk University Faculty of Agriculture Experimental Station in 2009 and 2010. There were considerable variations with respect to investigated characters among the ecotypes and also significant interactions over the years. According to two years results, investigated properties were varied from 83.5 to 126.5 cm for plant height, 102 to 116.5 days for days to harvest, 10.4 to 15.5 for pod number per plant, 3.5 to 5.6 for seed number per pod, 3.0 to 4.4 for lodging score, 67.3 to 227.4 g for 1000 kernel weight, 3.37 to 4.57 t ha-1 for straw yield, 1.50 to 2.21 t ha-1 for seed yield and 27.5 to 35.9 % for harvest index. As a result, Avcilar and Ortakent ecotypes were considered to be tested in location experiment for new variety development because these ecotypes performed more stable results across the years and higher yield performance.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
