| 總結: | Broadcasting is the most common practice followed by the farmers of Kuttanad region of Kerala for sowing paddy due
to the shortage and high cost of labour and lack of suitable machinery for transplanting. But it necessitates higher
quantity of seed (120-125 kg ha -1 ) and the resultant higher plant population leads to increased susceptibility to pests and
diseases. Drum seeder for wet seeding (line sowing) as an effective option for overcoming these disadvantages was
tested in comparison with the traditional broadcasting. Field trials were conducted in Muttar panchayath of Kuttand
region using paddy variety Uma during the Puncha (November-March) seasons of three years from 2011 to 2014. The
broadcasted plots had 170-190 hills sq.m -1 with less (492-566) number of productive tillers resulting in a grain yield of
5679 kg ha -1 whereas the drum seeded plots had only 36 hills sq.m -1 but with higher (630-868) number of productive
tillers yielding 6470 kg ha -1 . The average cost of cultivation using drum seeder was less (Rs. 41240 ha -1 ) compared to
that of broadcasting (Rs. 47343) with a B:C ratio of 2.82 and 2.16, respectively. Drum seeding has advantages like low
seed cost, optimum plant population, lesser use of fertilizer and plant protection chemicals, less labour requirement, and
its operation does not require any skill thus rendering it an economically and technologically viable practice for adoption
in paddy cultivation. |
