ABSTRACT
For study of the developmental phenology of Njavara under different management systems namely System of Rice Intensification SRI (M1), Integrated Crop Establishment Method (ICM) (M2), Package of practices (PoP) (M3) of Kerala Agricultural University and Farmers' practice (M4), an experiments was conducted in 2007 and 2008 at Cropping Systems Research Centre, Karamana, Thiruvananthapuram, Kerala. Growth characters like plant height, number of leaves hill-1, length and width of leaf and number of tillers hill-1 were recorded at weekly intervals. Result showed that, maximum plant height, number of leaves hill-1 and length and width of leaf were recorded in farmers practice followed by PoP, SRI and ICM. Number of tillers hill-1 was in the following order i.e. Farmers' practice > PoP > SRI > ICM and they differed significantly from one another. Growth stages like panicle initiation, maximum tillering, booting, flowering and physiological maturity were fixed based on observations recorded at 3 days intervals.
Key words :
Growth stages, Management systems, Njavara rice, Phenological development.
