Effect of different organic and inorganic fertilizers on nutrient content and uptake by summer sesamum (Sesamum indicum L.) in loamy sand

Abstract

Paddy is an important cereal crop in Malanad region of Chikkamagaluru district, Karnataka. The productivity is low due to non-adoption of improved package of practices. Therefore, efforts have been made to demonstrate improved production technologies in paddy to increase productivity. The present study was carried out by Krishi Vigyan Kendra, Chikkamagaluru, Karnataka to assess the impact of frontline demonstration on popularization of paddy variety KPR-1. Results showed the paddy variety KPR 1 had highest grain yield (50.5 – 60.5q/ ha) under rainfed condition in hill zone of chikkamagaluru during kharif season (2016-17 to 2018-19). An average yield of 55.73 q/ha was recorded in frontline demonstration and in farmer practices it was just 44.67q/ha. Thus, the average technology gap, extension gap and technology index of 6.43, 11.07 and 10.10 percent were observed between demonstration and farmer practices. The average yield of paddy increased by 24.61 percent over farmers’ practices.
