Effect of Substrate Media on Pea Sprouts Production

Abstract

The objective of this research was to study the effect of substrate media on pea sprouts production. The experimental design was Complete Randomized Design (CRD) consisted of 7 treatments: 1) peat moss 2) coconut coir 3) burnt rice husk 4) soil:burnt rice husk (1:1) 5) coconut coir:burnt rice husk (1:1) 6) coconut coir:burnt rice husk:soil (1:1:1) and 7) coconut coir:burnt rice husk:sand (1:1:1). The experiment was carried out during June to December 2020 at Microgreen Production Learning Center, Faculty of Agricultural Technology, Phetchaburi Rajabhat University. It showed that in the first harvest the substrate medium soil:burnt rice husk (1:1) provided the best results with the germination rate of 4.00 days, percentage of germination of 92.00%, germination speed index of 23.20, seedling height of 9.95 cm and fresh yield of 32.88 g. In the second harvest the substrate medium coconut coir:burnt rice husk:sand (1:1:1) provided the best results with the germination rate of 4.00 days, percentage of germination of 98.25%, germination speed index of 19.65,  seedling height of 8.94 cm and fresh yield of 17.56 g.
