INFLUENCE OF LIQUID ORGANIC FERTILIZERS ON THE YIELD STRUCTURE CHARACTERISTICS AND PRODUCTIVITY OF CHICKPEA (Cicer arietinum L.)

The aim of this study was to determine the effect of liquid organic fertilizers Naturamin Plus and Amalgerol Essence on the yield structure characteristics and productivity of chickpea (Cicer arietinum L.). The experiment was conducted in the period 2019-2021 in the region of South-Central Bulgaria. The trial was designed by the block method in 4 repetitions and 3 doses of fertilizers were tested in two phases of chickpea development: growth phase (4th leaf) and beginning of flowering. Results obtained for the yield were statistically processed by ANOVA. It was found that the treatment with the tested fertilizers increases the values of the structural elements of yield (number of pods per plant, number of grains per plant, grain mass per plant and 1,000 grain mass). The maximum increase in productivity was obtained with treatment with liquid organic fertilizer Amalgerol Essence in dose 1,000 ml.ha(-1) - 21.8% more compared to the control. A higher effect on productivity was found when applying the tested fertilizers in the beginning of flowering.
