Abstract
A field experiment was carried out at the Regional
Research Station, Anand Agricultural University. Anand during the
summer season of the year 2009-10 to study the “Response of
summer rice (Oryza sativa L.) to plant geometry and age of
seedlings under SRI method” The soil of the experimental plot
was loamy sand in texture having good drainage with 7.5 pH. The
soil was low in organic carbon and available nitrogen, medium in
available phosphorus and high in potassium. Nine treatment
combinations comprised of three plant geometry viz., (P1 : 10 x 10
cm, P2 : 20 x 20 cm, and P3 : 30 x 30 cm and three age of seedlings
viz., S1 (10-12 days), S2 (18-20 days) and S3 (28-30 days) were tried
in split plot design with four replications. The rice crop was fertilized
with recommended dose of fertilizer (100:25:00 kg N, P2O5 and 25
kg ZnSO4 ha-1). However, additional 25 per cent dose of nitrogen
was given from farm yard manure considering SRI method in rice.
