Effect of spacing, Azolla and levels of nitrogen on rice

Effect of spacing, Azolla and levels of nitrogen on rice

Madras Agricultural Journal 81(9): 514-515

In a field experiment in 1990/91 at Coimbatore, Tamil Nadu, rice IR 20 was grown at spacings of 20 or 15 x 10 cm with or without 200 g Azolla/msuperscript 2. The crop also received 0-240 kg N/ha. Grain yield was higher at the wider spacing and was increased by over 0.5 t with Azolla.
