A field experiment was carried out at ICAR-Krishi Vigyan Kendra, Tiruvallur to study the integrated crop management practices on yield and economics of brinjal at Tiruvallur District of Tamilnadu. Farmers were cultivated local varieties, adopted local technologies, getting low income, low yield and unaware new technologies for cultivation of brinjal. The studies were conducted on effect of integrated crop management practices on brinjal yield and economics through frontline demonstration at farmer’s field of Tiruvallur district, Tamilnadu during the year 2016-2017. Inputs like IIHR-Arka Vegetable Special, Pseudomonas fluoresences, Wota – T traps and yellow sticky traps were purchased and distributed to the ten identified farmers. There was significantly increased in brinjal yield (36.7 per cent), net return and B:C ratio after conduct of frontline demonstrations as compared to farmers practice. The adoption of integrated crop management practices through demonstrations programme, showed positive impact on brinjal yield and economics. Demonstration plot recorded higher technology gap (22.0 t/ha), extension gap (6.0 t/ha) and technology index (36.6 per cent), compare to local variety and also showed high percentage yield increase over local type and recorded 20 per cent increase yield.
