dc.description.abstractAn experiment was conducted at the Agricultural Research Station, Mannuthy, Kerala Agricultural University during May, 1988 to February, 1989 to study the influence of weather parameters on growth and yield of rice variety Jaya. The experiment was conducted in split plot design with twelve times of planting (June 18, July 2, July 16, July 30, August 13, August 27, September 10, September 24, October 8, October 22, November 5, and November 19) as main plot treatments and two spacings (20 x 10 cm and 20 x 15 cm) as subplot treatments and the treatments were replicated three times. Observations on all weather parameters were recorded daily. Crop growth characters like plant height and number of tillers at various stages of growth and time taken from transplanting to panicle initiation, panicle initiation to flowering and flowering to harvest were recorded. Yield components like number and percentage of productive tillers, length of panicle, number of spikelets per panicle, number and percentage of filled grains, grain yield, straw yield, drymatter production, thousand grain weight, harvest index and grain straw ratio were recorded. Observations on incidence of pests, diseases and nematodes were also recorded. However, no serious incidence was noticed. The time of planting greatly influenced all the growth and yield characters. Early plantings, generally recorded taller plants and more number of tillers and productive tillers. The time of planting had a significant influence on the duration taken from flowering to harvest. Number of spikelets and filled grains per panicle did not show any significant trend with delay in planting.en_US
