Agronomic Traits and Fruit Quality of Pineapple with Different Levels of Chicken Manure Application

Auraiwan Isuwan




Abstract


The responses of the pineapple (Ananas comosus (L.) Merr cv. Pattavia) grown in a fine-silty soil to
various levels of chicken manure, in terms of plant growth, and fruit yield and quality, were investigated at
a farm plantation in Petchaburi, Thailand. A randomized complete block design with 4 replications was used.
Treatments were the chicken manure applied in levels equivalent to 0 (control), 3, 6 and 9 g nitrogen (N)
plant-1. The manure was manually and thoroughly mixed with the soils, which was incubated for 30 days
prior to pineapple planting. Agronomic traits of the pineapple plants and chemical composition of the
pineapple fruits were determined. Plant growth and fruit size were linearly increased (p
