THE EFFECT OF COMMERCIAL ORGANIC AND INORGANIC FERTILIZERS AND RHIZOBIUM INOCULATION ON YIELD AND YIELD COMPONENTS OF FABA BEAN (VICIA FABA L.) AND PEA (PISUM SATIVUM L.)

Abstract

This research was conducted to determine the effect of organic and inorganic fertilizers and bacteria inoculation on yield and its components on pea and faba bean in Dicle University Agricultural Faculty, Diyarbakir, Turkey, during 2018 and 2019 growing seasons. The experiment was laid out following a split-plot in completely randomized block design, with three replications. Fertilization treatments and cultivars were designed as main and sub factors, respectively. Data on plant height, plant biomass, pod weight, seed yield per plant, number of pods and number of seeds per plant, biological yield, seed yield and 100-seed weight were recorded at harvest. Number of nodules and nodule dry weight were record in flowering time. The effect of inorganic nitrogen, organic fertilizers and bacteria inoculation on grain yield, seed yield per plant, biological yield was significant at both pea and faba bean. Inorganic fertilizer (urea) was increased the grain yield (2147 kg/ha) and biological yield (4956 kg/ha) in faba bean, but close to control (2080 kg/ha and 4690 kg/ha). Organic-1, Organic-2 and bacteria treatments were decrease the grain yield and biological yield on pea and faba bean, and this decrease on pea was almost half over control. The effect of treatments on number of nodules per plant on pea and faba bean was significant. The highest number of nodules per plant on pea was in bacteria inoculation (125.9) and control (121.5), and differences among nitrogen (109.1), Organic-1 (97.3) and Organic-2 (109.3) treatments was no significant.
