STUDIES ON NITROGEN AND POTASSIUM MANAGEMENT IN MAXIMIZING HYBRID RICE PRODUCTIVITY
1Department of Agronomy,
Agricultural College and Research Institute, Madurai – 625 104, India.
ABSTRACT
Field experiments were conducted at Agricultural College and Research Institute,
Madurai during kharif and rabi seasons of 2000 – 2001 and 2001-2002, to study the
effect nitrogen and potassium management in maximizing the productivity of hybrid
rice (ADTRH 1 and CORH 2). The experiments were laid out in randomized block
design with three replications. The treatments included sources and levels of nitrogen
and split application of N and K. The results revealed that application of 10 t ha-1
green manure along with 200kg ha-1 inorganic nitrogen improved the yield and yield
attributes of rice hybrids (ADTRH 1 and CORH2) and also recorded higher yield
(8210 kg ha-1 in kharif and 7775 kg ha-1 in rabi seasons) Similarly, application of N
and K in four equal splits at active tillering, panicle initiation, booting and flowering
recorded higher yield ( 7598 kg ha-1 in kharif and 7272 kg ha-1 in rabi seasons).
