EFFECT OF MICROBIAL INOCULANTS AND INORGANIC FERTILIZERS ON GROWTH AND YIELD OF HYBRID CABBAGE (BRASSICA OLERACEA L. VAR.CAPITATA)

Abstract

The present investigation was conducted to know the effect of different levels of inorganic fertilizers viz., F1=80:40:40 Kg NPK/ha, F2=120:60:60 Kg NPK/ha, F3=160:80:80 Kg NPK/ha, F4=200:100:100 Kg NPK/ha and F5=240:120:120 Kg NPK/ha and bio-fertilizers viz., M0-0, M1-Azotobacter, M2-Azospirillum, M3-VAM and M4-PSB. The experiment comprised of 25 different treatment combinations and replicated thrice. Results from the study indicated that combined application of NPK @ 200:100:100 Kg/ha along with seedling treatment with Azospirillum gave significantly higher plant height (30.40cm), plant spread (54.50cm), head diameter (24.32cm), head depth (21.71cm), head weight (1.878 Kg) and head yield (868.70 q/ha). However, days taken to head formation and head maturity, number of outer leaves/plant and number of inner leaves/head did not show significant interaction effects. Therefore, it may be concluded that combined application of NPK @ 200:100:100 kg/ha along with seedling treatment with Azospirillum was the most effective treatment combination for higher growth and yield in cabbage.
