Effect of organic and inorganic fertilizers on growth yield and nutrient content of bird chilli Capsicum fructescence

Vimala P., . and Melor R., . and Shokri O., . and Balasubramaniam P., . (2005) Effect of organic and inorganic fertilizers on growth yield and nutrient content of bird chilli Capsicum fructescence. [Proceedings Paper]

This study investigated the response of bird chilli Capsicum fructescence grown on a clay soil to rates of organic and inorganic fertilizers. Four rates 0 20 40 60 t/ha of processed poultry manure PPM and three rates 0 2 and 3 t/ha of inorganic fertilizer NPK were evaluated. Significant effects of poultry manure and inorganic fertilizer rates on yield were obtained. Interaction effects between PPM and NPK were not significant. Yield increased significantly from 6.46 t/ha at zero fertilizer to 15.49 t/ha at 20 t/ha PPM 2.0 t/ha NPK N:P‚‚0‚:K‚‚0:Mg0 12:12:17:2 . A significant quadratic yield response to the inorganic fertilizer was obtained represented by the equation Y 9.15 5.08x - 1.33x where Y yield in t/ha and x fertilizer applied in t/ha. The optimum rate of inorganic fertilizer was 1.91t/ha. Nutrient contents did not differ significantly except for fruit Ca Fe and Mn and leaf Mg and Mn. It is concluded that 20 t/ha PPM 1.9 t/ha NPK 12:12:17:2 compound fertilizer can be used as a guide for the conventional cultivation of bird chilli on clayey soil. For organic cultivation of bird chilli at least 40 t/ha of PPM is required.

Abstract

This study investigated the response of bird chilli Capsicum fructescence grown on a clay soil to rates of organic and inorganic fertilizers. Four rates 0 20 40 60 t/ha of processed poultry manure PPM and three rates 0 2 and 3 t/ha of inorganic fertilizer NPK were evaluated. Significant effects of poultry manure and inorganic fertilizer rates on yield were obtained. Interaction effects between PPM and NPK were not significant. Yield increased significantly from 6.46 t/ha at zero fertilizer to 15.49 t/ha at 20 t/ha PPM 2.0 t/ha NPK N:P‚‚0‚:K‚‚0:Mg0 12:12:17:2 . A significant quadratic yield response to the inorganic fertilizer was obtained represented by the equation Y 9.15 5.08x - 1.33x where Y yield in t/ha and x fertilizer applied in t/ha. The optimum rate of inorganic fertilizer was 1.91t/ha. Nutrient contents did not differ significantly except for fruit Ca Fe and Mn and leaf Mg and Mn. It is concluded that 20 t/ha PPM 1.9 t/ha NPK 12:12:17:2 compound fertilizer can be used as a guide for the conventional cultivation of bird chilli on clayey soil. For organic cultivation of bird chilli at least 40 t/ha of PPM is required.
