The effect of fertilization on yield and yield components on some chichkpea varieties

This research was carried out in Diyarbakır during the early spring growing period in 2018. This research aimed to determine the effect of diammonium phosphate, triple superphosphate, urea and Rhizobium ciceri bacteria applications in Gökçe, Diyar 95, Aziziye 94 and Taek- Sağel on yield and yield components. It was investigated the number of plants per plot, the days to emergence, days to 50% flowering, days to maturity, number of nodule per plant, nodule dry weight per plant, leaf area, plant height, number of main branches per plant, number of pods per plant, seed yield and 100 seed weight in the study. The experiment was arranged in the factorial design with three replications, the plots were arranged in 4 rows in 3 m length and 40 cm in row spaces. The seed density was calculated on 50 seeds per square meter. Sowing date performed in February 7, 2018. The number of nodules per plant was low (110.5), low in control (81.6) and bacterial (85.1) in the pre-flowering period. DAP (113.7) and (108.7) phosphorus applications were high, urea (88.5) and bacterial applications (85.1) were found during the flowering period. Yield ranged from 132.4 kg/da to 187.3 kg/da for fertilizer application. The DAP application gave high value. Bacteria application gave the second high value for grain yield (169.0 kg/da).The TSP application for seed yield was low.
