Morning FOG Benefits| 63 DAS Panicle Formation to Booting

Morning fog and the associated early morning humidity provide several key benefits to rice crops, particularly in terms of  moisture management, heat stress mitigation, and physiological conditioning.  Improved Hydration and Water Status: Early morning dew and fog help keep the rice crop h useydrated before sunrise. This high humidity improves the leaf water content, allowing the plant to maintain a better physiological state. Reduced Heat Stress: The fog layer keeps ambient temperatures cooler in the early hours. This is critical for preventing heat stress, particularly during the sensitive flowering stage of the rice plant. Maximized Photosynthetic Activity: By reducing early morning water stress, the fog allows the plant to rapidly activate photosynthesis as soon as the sun rises, maximizing the crucial morning growth period. Synergy with Early Morning Flowering (EMF): Rice varieties with the Early Morning Flowering (EMF) trait flower during cooler, foggy, or humid hours to avoid high-temperature-induced spikelet sterility. The fog ensures that the environment remains within the optimal temperature range for this process. Moisture Retention in Soil: Foggy, high-humidity conditions contribute to maintaining moisture in the soil, which can be beneficial in conjunction with irrigation techniques like Alternate Wetting and Drying (AWD).  #agriculture #drone #farmer #farming For a rice variety with a 118-day maturity (short-to-medium duration) grown via direct seeding, the reproductive stages generally follow a 30–35 day timeline. Based on a typical 120-day maturity formula, the breakdown for the specific stages is as follows:  IRRI Rice Knowledge Bank Panicle Initiation to Booting: Approximately 11–16 days (beginning around 55–60 days after sowing). Booting to Heading: Approximately 8–10 days or more. Total Reproductive Phase (Panicle Initiation to Heading): Approx. 20–25 days.  Facebook +3 In direct-seeded rice, the panicle initiation (PI) generally occurs around 55–60 days after sowing (DAS).  Facebook +1 Detailed Breakdown for 118-Day Direct Seeding: Panicle Initiation (PI): ~55–60 DAS Booting Stage: ~65–75 DAS Heading Stage: ~75–85 DAS Ripening/Maturity: ~85–118 DAS  ScienceDirect.com +3 Note: The reproductive phase (PI to flowering) is generally consistent, while differences in total maturity duration are mostly determined by the length of the vegetative phase.  IRRI Rice Knowledge Bank +3
