Effect of different dose of fertilizer application on growth parameter of chilli and uptake and micronutrient concentration after harvest of the crop

Abstract

Field experiment was conducted during Kharif 2011 on a farmer’s field in Koliwad (Hubli Taluk) village in northern transitional zone of Karnataka between 1521' N latitude and 7524' E longitude and at an altitude of 629 m above mean sea level (MSL). In the soil test crop response dose of 216:116:166 N:P 2 O5:K 2 O kg ha, recorded significantly higher plant height (95.4cm) over remaining treatments. This was at par with treatments T 5 (93.5 cm) and lowest plant height (85.8 cm) was recorded in RDF (T 1 ) at harvest. T 2 (STCR) registered highest number of branches (30.2), which was significantly superior over remaining all the treatments. The application of STCR dose of N, P 2 O 5 and K 2 O (T 2 ) recorded higher dry matter production (120.7 g) which was significantly superior over RDF (T 1 ), STL (T 3 ) and modified RDF 1 (T 4 ). The concentration of N, P and K were higher in the treatment T 2 (STCR dose N, P 2 O 5 and K 2 O) as compared to rest of the treatments. There was significant difference among treatments with respect to zinc concentration in plant as the soil was deficient in zinc.
