“…Weather indices: The best agro meteorological indices to incorporate in the agro meteorological yield forecast model at F and F stage in maize crop was Tmax (Z11), T min (Z21), 2 3Tmax X Tmin (Z121), Tmin XRF (Z230),RF X RH II (Z350). In Udhampur district, the best agro meteorological indices at F 2 (pre flowering stage) and F (pre harvesting stage) were 3 Tmax (Z11), RH II(Z51), Tmax X Tmin (Z121), Tmax X RH II (Z141), RFXRH I(Z 341) and RF XRH II(Z351).Similar, results were also reported byPatel et al (2018). The validation of results of statistical model during 2020 kharif and results reported that the percent deviation in maize yield at F stage was 2.57 percent and 9.15percent in Jammu and 2 Udhampur district whereas at F stage the percent deviation 3 in maize yield in Jammu and Udhampur district were -3.00…”
