Field germinability and storability of rice seeds treated with maleic hydrazide spray

摘要

Investigations were carried out at Rice Research Station, Ambasamudram to induce seed dormancy in rice seeds (Var. ASD 16) and to arrest sprouting in field under inclement weather condition at Ambasamudram during the harvest of the 1st season (Kar) crop, maleic hydrazide at 200 ppm and 500 ppm concentration spray was given to the standing crop of rice 10, 15, 20 & 25 days prior to harvest.
