YIELD COMPONENTS IN MUNG BEAN [Vigna radiata (L.) Wilczek]

Huseyin CANCI, Cengiz TOKER

Abstract

This study was conducted to evaluate the yield components in mung bean [Vigna radiata (L.)Wilczek] using the correlation, path and factor analyses. It was found that there was considerable variation for the characters studied. Factor 1 composed of 100-grain weight, podlength, pod width, branches per plant and pods per plant. The grain weight was stronglycorrelated with pod length and pod width. Pods per plant were significantly and positivelyassociated with branches per plant. Factor 2 consisted of biological, straw and grainyields. The seed yield was highly associated with biological and straw yields. Factor 3comprised of seed per pod, pods and flowers per peduncle. The fourth factor was onlythe days to flowering. The last factor was plant height. The total factors had 74% ofthe total variance induced by the characters. It was firstly concludedthat the factor analysis together with path and correlationcoefficients could successfully be used for determining characters usable for selection in themung bean breeding programs.

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.
