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 />
