Nutrition of container-grown tuberous begonias

Abstract

Begonia x tuberhybrida was grown in a peat:sand:sawdust (1: L1,v/v) potting medium using a four factor central composite incomplete block design to measure the response to N,P,K fertilisation and liming, each at five levels. This plant responded strongly to Nand P. Nitrogen was singularly the most important nutrient element and its effects were enhanced by P fertilisation and liming.
