A research trial was conducted in clay loam soils at Regional Agricultural Research Station,
Maruteru, Andhra Pradesh during rabi, 2022-23 to assess the effects of puddling and crop
establishment methods on rice productivity.The study comprised two factors: puddling practice,
viz., power tiller (M1
), rotovator (M2
,) and roto-puddler (M3
) as main plot treatments and crop
establishment method, viz..,drum seeding (E1
),line planting (E2
),machine planting (E3
),diagonal
planting (E4
,) and Bengal planting (E5
) as sub-plot treatments.The results showed that among
the puddling practices, the use of a roto-puddler registered the highest growth parameters at
harvest, such as number of tillers m-2 (401), crop dry matter (11053 kg ha-1), and yield attributes,
that is, the number of panicles m-2 (371), total number of grains panicle-1 (259), grain (4697 kg
ha-1), and straw yield (6098 kg ha-1). This was statistically at par with the use of a rotovator but
significantly superior to that of a power tiller. Among crop establishment methods, growth
parameters at harvest, that is, number of tillers m-2 (416), crop dry matter (11427 kg ha-1), and
yield parameters, that is, the number of panicles m-2 (386), total number of grains panicle-1 (257),
grain (4837 kg ha-1), and straw yield (6148 kg ha-1) were higher with the diagonal planting method;
however, it was found statistically at par with Bengal planting and drum seeding but significantly
superior over machine planting and line planting.
