Effect of organic acid coated phosphatic fertilizer on soil P status, yield and quality of Brinjal


Author(s): Anju Mohan, P Malarvizhi, RK Kaleeswari and T Saraswathi

Abstract: A field experiment was conducted during Rabi, 2019 which is laid out in Randomized Block Design (RBD) with ten treatments and three replications. The treatments comprised of T1: NK+ P as uncoated DAP, T2: NK + P as FA coated DAP (5%), T3: NK + P as FA coated DAP (10%), T4: NK + P as FA coated DAP (15%), T5: NK + P as FA coated DAP (20%), T6 NK + P as HA coated DAP (5%), T7: NK + P as HA coated DAP (10%), T8 : NK + P as HA coated DAP (15%), T9 : NK + P as HA coated DAP (20%), T10: Control. Urea and MOP were used as the source of Nitrogen and potassium respectively. The results from the field experiment revealed that the available P in the soil, the yield of Brinjal(CO2) and the economic returns are varying according to the change in coating concentration and type of organic acids,. There is no significant difference in anthocyanin content and Titrable acidity of Brinjal fruits but slight improvement is found in ascorbic acid content. Significantly higher yield was obtained in T9 [NK + P as HA coated DAP (20%)] and lowest yield was recorded for T10, T6 and T1. Humic acid coated treatments found better in yield and available soil P status compared to Fulvic acid coated treatments.
