INFLUENCE OF BACTERIA AND CHICKEN MANURE ON YIELD AND YIELD COMPONENTS OF BEAN (Phaseolus vulgaris L.)

Kazim CUKURCALIOGLU, Engin TAKIL, Nihal KAYAN

Abstract

The effects of chicken manure and different bacteria applications on yield and yield components of beans were investigated in present study. The field experiment was conducted during the 2019 and 2020 at the experimental area of the Faculty of Agriculture, Eskisehir Osmangazi University, Eskisehir, Turkey. Experiment laid out as split plot based on randomized complete block design with three replications. Chicken manure (chicken manure + and chicken manure -) were main plots and bacteria applications (control; traditional; rhizobia; phosphorus dissolving bacteria; traditional + rhizobia; traditional + phosphorus dissolving bacteria; rhizobia + phosphorus dissolving bacteria; traditional + rhizobia + phosphorus dissolving bacteria) were sub-plots. All of the investigated characters were higher in second year than first year except for harvest index and hundred seed weight due to especially June precipitation in second year. Grain yield increased from 1233 kg/ha to 3111 kg/ha in the second year of the experiment. Application of chicken manure positively affected important yield components, chlorophyll content and yield. Grain yield increased by approximately 5% with the application of chicken manure. In general, the application of bacteria alone or together has positively affected yield and yield components. The highest yield was obtained from traditional+rhizobia+phosphorus dissolving bacteria application. Grain yield in terms of bacterial applications varied between 1915 and 2488 kg/ha. Consequently, it was determined that the efficiency of bacteria increased with the application of chicken manure and positive results were obtained in yield and yield components of beans.

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.
