This study was conducted at the open field of the Vegetable Project of Quezon National Agricultural School, Silangang Malicboy, Pagbilao, Quezon from June to September 2015 to evaluate the effect of spatial arrangement of carrots and broccoli on growth and yield of the plants when applied with different levels of vermicompost. Two factors were considered as Factor A: Spatial Arrangement, Factor B: Level of Vermicompost. Single, double and triple row was used for spatial arrangement and 1 ton/ha, 3 tons/ha, 5 tons/ha and 7 tons/ha for levels of vermicompost.
The study used a 3 x 5 factorial experiment in Randomized Complete Block Design with four (4) replications. It aimed to evaluate the effect of spatial arrangement on the growth and yield of carrots intercropped with broccoli; determine the effects of different levels of vermicompost on the growth and yield of carrots and broccoli; evaluate incidence of pests and diseases of carrots and broccoli; and determine the cost and return on production of carrots and broccoli in different spatial arrangement and application levels of vermicompost.
Spatial arrangement and different levels of vermicompost affect yield of carrots in terms of weight, diameter and length. However, it does not significantly influence plant height increment of carrots and broccoli and number of leaves of broccoli. Higher levels of vermicompost application enhances the diameter, length and weight of the carrots at harvest.
