Pot experiment was conducted to assess the effects of high-temperature stress on rice (Oryza sativa L.) and to identify effective mitigation strategies in kharif season (2023) in the Department of Agricultural Meteorology, Kerala Agricultural University in a factorial CRD layout. The rice variety Jyothi was exposed to high-temperature (HT) in a tem...
Mango ( Mangifera indica L.) is of great economic importance, especially in India, where diverse agroclimatic conditions support the cultivation of numerous varieties, solidifying the nation's leading position in the global market. In Muthalamada, Kerala, unique geographic and climatic factors enable early mango production, offering a market edge....
Monthly rainfall data for the 14 districts of Kerala from 1985 to 2014 were used in the present analysis to compute the annual and seasonal rainfall. IITM's Sub divisional monthly rainfall data from 1951-2014 has been also used to get a clear picture of the El Niño effect on rainfall variability in Kerala. District-wise area, production and product...
The trend in annual and seasonal rainfall over Kerala from 1991 to 2012 is studied here using Mann Kendall trend test. A significant decrease in annual, southwest monsoon and northeast monsoon rainfall is observed over many parts of Kerala. Decreasing trend in annual and southwest monsoon rainfall is more prominent over southern zone of Kerala and...
Field experiment was conducted at Agricultural Research Station, Mannuthy, KAU, Thrissur during the kharif season of 2014 with rice variety Jyothi and five dates of planting viz., June 5 (D1), June 20 (D2), July 5 (D3), July 20 (D4), and August 5 (D5). CROPWAT model was used to determine crop evapotranspiration and irrigation requirement at differe...
A field experiment was conducted during Kharif season of 2016 at Kerala Agricultural University, Agricultural Research Station, Mannuthy, Thrissur. To study the phenology, and various agrometeorological indices viz., accumulated growing degree days (GDD), helio thermal units (HTU), photo thermal units (PTU), of selected rice cultivars grown under d...
Monthly rainfall data for the 14 districts of Kerala from 1985 to 2014 were used to compute the annual and seasonal rainfall viz. southwest monsoon (June-September), Northeast monsoon (October-December) and summer rainfall (March-May) and IITM's Sub divisional monthly rainfall data from 1951-2014 was also used in the present analysis. The interannu...
A field experiment was conducted at Thrissur during kharif seasons of 2013 and 2014 using two rice varieties (Jyothi and Kanchana) and five dates of planting (June 5th, June 20th, July 5th, July 20th and August 5th). CERES-Rice model of DSSAT v 4.6 was used to simulate the phenology and grain yield of rice. Calibration of genetic coefficients was d...
