Abstract: A field experiment was conducted during the kharif season 2007 on farmers’ fields at Rottigawada village, Kundgol taluk of Dharwad district to study the “Response of chilli (Capsicum annuum L.) to Site Specific Nutrient Management Through Targeted Yield Approach in Northern Transition Zone of Karnataka”. The treatments were targeted yield levels of 10 q/ha, 15 q/ha, 20 q/ha, 25 q/ha and 30 q/ha of chilli dry fruit. The application of higher doses of fertilizer significantly influenced the growth and yield components. The targeted yield level treatment of 30 q/ha recorded significantly higher growth and yield characters. The achieved dry fruit yield of chilli was significantly superior over targeted yield level treatments of 10 q/ha (12.50 q/ha) 15 q/ha (16.00 q/ha), 20 q/ha (21.06 q/ha) and 25 q/ha (27.43 q/ha) as per the t-test of significance for unequal variance. However, the higher targeted yield level of 30 q/ha was significantly lower than the targeted yield level (28.43 q/ha). The total uptake of nutrients was recorded significantly higher in targeted yield level treatment of 30 q/ha. The same trend was followed with respect to available nutrient status of soil after harvest of the crop. The quality parameters such as Ascorbic acid (190.7 mg/100 g fruits), Oleoresin content (16.50%) and Colour value (319.0 ASTA units) was higher in the targeted yield level of 25 q/ha. The higher net return was recorded in the targeted yield level treatment of 30 q/ha (Rs.1, 25,788 ha-1). However, B: C ratio was higher in the targeted yield level treatment of 25 q/ha (2.58). The study revealed that the significantly higher targeted yield and improved quality and higher B: C ratio could be achieved up to targeted yield level of 25 q/ha under rain fed condition of Northern Transition Zone of Karnataka.
