The Effects of DAP (Diammoniumphosphate) Fertilizer Doses on Grain Yield and Some Yield Properties of Chickpea (Cicer arietinum L.) in the Ecological Conditions of Siirt Province

Abstract

This research was conducted in 2018-2019 to determine the effects of different DAP fertilizer levels on the grain yield and some yield characteristics of chickpea in the ecological conditions of Siirt. DAP (Diammonium phosphate) fertilizer was used doses of 0, 3, 6, 9, 12 and 15 kg/da in the study. Trials were laid out in 3 replications according to a randomized block design. Within the scope of this research, plant height, first pod height, pod number per plant, number of seeds per plant, 100-grain weight and grain yield parameters were examined. Within the scope of this research, plant height, first pod height, pod number per plant, number of seeds per plant, 100-grain weight and grain yield parameters were examined. According to the results obtained from the study, plant height is 52,1-60,2 cm, first pod height is 29,8-36,5 cm, number of pods per plant is 17,2-31,7 pcs/plant, number of grain per plant is 18,3-33,2 pcs/plant, 100-grain weight is 30,4-34,0 g and yield varied between 101,2-165,4 kg da^-1. In terms of all the parameters examined, it was determined that the most suitable DAP fertilizer dose in cultivation of chickpea in Siirt is 15 kg da^-1.
