Abstract
An experiment was conducted at the College of Horticulture, Vellanikkara during 1979-80 on the effect of shade and moisture regimes on the growth of cocoa Theobroma cacao L.) seedlings.
The investigations were carried out to arrive at the optimum shade and moisture requirement for the growth of cocoa seedlings.
The experiment was laid out in a completely randomised design with four levels of shade and three levels of moisture with four replications.
The study revealed that cocoa seedlings must be shaded and well watered for their better growth. 50 – 55% shade and irrigation at 75% available moisture was found best. Death of all the seedlings in the open by the third month of observation stresses that, cocoa seedlings cannot be grown without any shade irrespective of the frequency of irrigation. Expect net assimilation rate (NAR) and leaf area ratio (LAR) all the growth characters were increasing with increasing shade (up to 50 – 55%) and increasing frequencies of irrigation.
