ABSTRACT<br />
Field experiments were conducted on direct sown paddy using eight-row drum seeder under puddled<br />
condition in farmers fields of Vizianagaram district, Andhra Pradesh during Kharif season for three years from 2007-<br />
2008 to 2009-2010 to evaluate the efficiency of drum seeder at different seed rates. (20, 30 and 40 kg ha -1 ) and<br />
optimum seed rate was quantified. The results showed that use of drum seeder at 30 kg seed ha -1 recorded increased<br />
grain yield by 26 and 22 per cent (7.58 t ha -1 ) respectively over that of 20 and 40 kg ha -1 seed rate. It was also found<br />
superior to normal transplanting and broadcasting of sprouted seed @ 75 Kg ha -1 . Drum seeder technology at 30 kg<br />
seed per ha reduced the seed rate by 45 kg ha -1 compared to broadcasting of seed on puddled soil and resulted in<br />
higher returns to farmers over normal transplanting/ broadcasting of sprouted seed.<br />
Transplanting is the most common method<br />
of crop establishment in rice cultivation under low<br />
land situation and is highly labour-intensive and<br />
expensive operation. In contrast, broadcasting of seed<br />
causes uneven plant stand, low yields and returns.<br />
In Vizianagaram district, Andhra pradesh, the major<br />
rice area is under tanks and success of crop depends<br />
on rainfall received. In many years overaged<br />
seedlings are planted due to delayed monsoon.<br />
Further, transplanting is not profitable due to high<br />
labour wages and problem of non-availability of labour<br />
during peak period of operation (Singh et al.,2005).<br />
Transplanting alone costs about 15% of total rice<br />
production cost and delayed transplanting due to<br />
labour shortage causes sustainable loss in yield<br />
(Ponnuswamy et al.,1999). Therefore, there is need<br />
of alternative methods to replace transplanting to<br />
tackle the problems of high cost of production and<br />
labour scarcity.<br />
Direct sowing of sprouted seed in puddled<br />
fields using drum seeder reduces the input costs<br />
i.e.,cost of seed, nursery raising, transplanting and<br />
it is a good method under late onset of monsoon .<br />
The present study was conducted in farmers<br />
fields to fine tune drum seeder technology with<br />
different seed rates for its large scale adoption and<br />
higher yields.<br />
MATERIALS AND METHODS<br />
The DAATT Centre,Vizianagaram introduced<br />
8 row paddy drum seeder made of fibre supplied by<br />
KSNM marketing, Coimbatore through AGROS<br />
during kharif, 2007 in Vizianagaram dsitrict. On farm<br />
trials were conducted during kharif season of 2007,<br />
2008 and 2009 to demonstrate the performance of<br />
drum seeder for direct sown paddy under puddled<br />
condition. Five villages were selected to carry out<br />
on-farm trials on purposive random sampling. These<br />
five villages were considered as five replications. Two<br />
hectares was allotted as a representative area for<br />
testing the performance of drum seeder in farmers<br />
fields with 5 treatments viz.,T 1<br />
, farmer’s practice of<br />
transplanting; T 2<br />
, farmer’s practice of broadcasting<br />
seed using 75 kg ha -1 ; T 3<br />
,seeding sprouted seed @<br />
20 kg seed ha -1 using drum seeder; T 4<br />
, seeding<br />
sprouted seed @ 30 kg seed ha -1 using drum seeder;<br />
T 5<br />
, seeding sprouted seed @ 4 0 kg seed ha -1 using<br />
drum seeder . Seeding of nursery was also done on<br />
the same day and 30 day old seedlings were<br />
transplanted in T 1<br />
and 75 kg ha -1 dry seed was<br />
broadcasted in T 2<br />
. In treatments T 3,<br />
T 4<br />
and T 5<br />
,<br />
sprouted seeds were sown at three seed rates using<br />
drum seeder. For direct sowing using drum seeder,<br />
the paddy seeds are soaked in water for 24 hours<br />
followed by incubation in gunny bags for 24-48 hours<br />
depending upon the rice variety and prevailing<br />
temperature. The field was well puddled and levelled<br />
after draining the standing water before sowing to<br />
avoid damage of sprouted seed and to enable water<br />
to spread uniformly over the field. After puddling, the<br />
field is left for 1-2 days for settling of the puddled<br />
soil. Using drum seeder, seed rate required for direct<br />
