| dc.description.abstract | An investigation was undertaken at the Regional Agricultural Research Station, Kumarakam during 1984-85 to identify a suitable variety of tapioca maturing in about six months and to find out the effect of different fertilizer doses on such varieties in the uplands of Kuttandu. The experiment was laid out in Factorial Randomised Block Design with three replications. The treatments consisted of three varieties namely Thoottakoli Kaduthuruthy. local and Sree Sahya and five fertilizer levels viz* 30:30:30, 30:30.45, 50:50:50, 50:50:75 and 50:50:100 Kg/ha of N P K. The varieties and fertiliser levels tried showed significant differences in the growth characters of tapioca. In all the three varieties the fertiliser level 50:50:100 recorded maximum plant height, leaf number and loaf area index. The yield and yield attributes were also influenced by the varieties and fertiliser levels. Maximum tuber yield was obtained from the variety Kaduthuruthy local (27.13 t/ha}. Tho variety Thottakolli produced 26.86 t/ha. In all the three varieties, highest tuber yield was observed in the 50:50:100 kg/ha N P K level. | en_US |
