ENVIRONMENTAL EFFECTS ON GROWTH AND YIELD OF GROUNDNUT
1Regional Agricultural Research Station, Tirupati - 517 502, India
ABSTRACT
Field experiments were conducted by taking up sowings of groundnut at fortnightly intervals through out the year to study the environmental effects on growth and partitioning. Mean maximum temperatures that prevailed during the crop growth had significant negative correlation with pod and kernel yield and yield attributes. Day length, mean minimum air temperature and mean soil maximum temperatures had similar influence. Highest pod and kernel yields were obtained when the sowings coincided with shorter days and lower temperatures. Mean minimum air temperature, day length and incident solar radiation were positively related with total dry matter production. Mean maximum temperature was positively associated with haulm yield. Longer days and higher temperatures also delayed harvests.
