EVALUATION OF IMPACT OF WEATHER ON MULBERRY LEAF YIELD

摘要

A synthetic yield-weather model on mulberry was developed through mining of archived yield and spatio temporal weather data for the period from Oct, 2002 to Sept, 2013. The data sets were finally re-analyzed crop-wise into 16 agro-meteorological variables vis-a-vis yield data of ruling mulberry variety S1635. Data were subjected to regression analysis. The ensuing equation led to construction of the final synthetic yield-weather model of mulberry foliage under standard package of practices(irrigated) at 24°06'North Latitude and 88° 15' East Longitude geo-referencing the institute farm. Retrospective model validation for the regression equation developed with data from 2002-03 to 2009-10 vis-a-vis the rest of the period under study i.e. from 2010-11 to 2012-13 confirmed that there had been no significant deviation of mulberry foliage yield from the prediction.
