Growth and production of dwarf coconut in saline-sodic soil under doses of potassium sulfate
ABSTRACT The objective was to study the influence of potassium sulfate doses applied to the soil on the growth and production of green dwarf coconut (Cocos nucifera L.) grown in saline-sodic soil. The experiment was conducted from January 2013 to January 2016, in a commercial plantation in the Secto...
