Abstract
Integrated nutrient management is essential for sustaining productivity and soil health in vegetable-based systems. A field experiment was conducted during summer 2022-23 at Dr. PDKV, Akola, to evaluate the combined effect of NPS compost and foliar-applied humic acid on yield, nutrient concentration, and nutrient uptake of brinjal (Solanum melongena) grown in Vertisols. The experiment was laid out in randomized block design with nine treatments and three replications. The nine treatments consists of a 100% recommended dose of fertilizer (100:150:100 kg N, P2O5 and K2O ha-1) (T1 ), 100%RDF+ FYM @ 5 t ha-1 (T2 ), 100%RDF+ NPS compost @ 2.5 t ha-1( T3 ),100%RDF+ FYM @ 5 t ha-1 + 4 sprays of HA @ 0.5% (T4 ), 100%RDF+ FYM @ 5 t ha-1 + 4 sprays of HA @ 1%(T5 ), 100%RDF+ FYM @ 5 t ha-1 + 4 sprays of HA @ 1.5%(T6 ), 100%RDF+ NPS compost @ 2.5 t ha-1 + 4 sprays of HA @ 0.5%(T7 ), 100%RDF+ NPS compost @ 2.5 t ha-1 +4 sprays of HA @ 1% (T8 ), 100%RDF+ NPS compost @ 2.5 t ha-1 + 4 sprays of HA @ 1.5% (T9 ). Organics (NPS compost and FYM) were applied at transplanting. Results revealed that integrated application of RDF, NPS compost @ 2.5 t ha-1 and four foliar sprays of humic acid @ 1.5% significantly enhanced fruit yield (41.01 t ha-1) and straw yield (47.55 q ha-1) compared to RDF alone. The same treatment also recorded the highest concentrations and uptake of nitrogen, phosphorus, potassium, and sulphur in both fruit and plant. Total nutrient uptake reached 271.57, 68.70, 284.70, and 45.58 kg ha-1 for N, P, K, and S, respectively, indicating improved nutrient use efficiency. The superior performance of combined treatments may be attributed to enhanced nutrient availability, improved root growth, and increased metabolic activity induced by humic substances and compost enrichment. The findings demonstrate that integrating NPS compost with foliar humic acid application is an effective strategy for improving brinjal productivity and nutrient uptake under Vertisol conditions, thereby supporting sustainable vegetable production systems.
