Abstract:

Rainfall is one of the key component of meteorological parameter that influence crop production. Here, the distribution of rainfall studied by Pearsonian coefficient to the rainfall data recorded over 30 years (1990-2020) for the Prakasam district. In this context crop yield –weather relations, is requisite to account for the influence of improved technology on the crop yields. Analysis has been carried by using 30 year (1990 - 2020) weather data and yields of Redgram. In this study, the concept of continuous time effect in the crop yields in contrast to introducing a discrete-time effect (technology effect) using Kharif yields to Red gram in the Prakasam district. The kharif redgram yield data of 30 years (1990 - 2020) used for the study. Inter annual variability is extensively considered amongst the wide range of time scales. An attempt to estimate decadal analysis by dividing the 30 years in to 3 subperiods each sub period as 10 year identified as relevant. This evokes to examine the individual crop yield –weather relationship corresponding to the technological sub periods is essential for weather response with crop growth stages.
