EFFECT OF IPNS AND FOLIAR NUTRITION ON NUTRIENT UPTAKE OF CORIANDER AND FERTILITY STATUS OF ALFISOLS IN TAMIRABARANI COMMAND AREA

A field experiment was conducted at Agricultural College and Research Institute, Killikulam, during Rabi season 2017-18 to study the effect of IPNS and foliar nutrition on yield and quality of coriander and its impact on the properties of Alfisols of Tamirabarani command area. The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and three replications. The treatments consists of absolute control (T1), STCR-IPNS alone (T2), FYM on 100 percent N equivalent basis alone (T3), along with T2, T3 foliar spray of amino acids, micronutrients, moringa and aloevera leaf extract alone and also in combinations. The treatment that received FYM + foliar spray of amino acids, micronutrients, moringa and aloe vera leaf extracts (T13) recorded higher uptake of nitrogen (14.89 kg ha-1 in seed and 16.04 kg ha-1 in stover), phosphorus (3.72 kg ha-1 in seed and 4.07 kg ha-1 in stover) and potassium (16.72 kg ha-1 in seed and 23.10 kg ha-1 in stover) in coriander at post harvest stage. The soil fertility status as evidenced by available nitrogen (177 kg ha-1), available phosphorus (15.4 kg ha-1) and available potassium (279 kg ha-1)at post harvest stage was higher in the treatment that received STCR-IPNS + foliar spray of amino acids, micronutrients, moringa and aloe vera leaf extracts (T12).
