VARIOUS IMPACTS OF DOSAGE AND TIME OF BIO-ORGANIC FERTILIZER APPLICATION TO THE GROWTH AND PRODUCTION OF SHALLOT (Allium ascalonicum L.)
Abstract
Organic matter has the ability to improve physical, chemical and biological properties of the soil to support crop productivity. Provision of bio-organic fertilizer will increase the growth and production of shallots. The aim of this study was to obtain the dosage and time of application of bio-organic fertilizer on the growth and production of shallots (Allium Ascalonicum L.). The study used a factorial randomized block design of two factors with three replications. The first factor is the dose of bio-organic fertilizer with 3 levels, namely: P1 = 425 gram bio-organic fertilizer/ plot, P2 = 525 gram bio-organic fertilizer/ plot, P3 = 625 gram bio-organic fertilizer/ plot, while the second factor when the application of bio-organic fertilizer: W1 = 2 MBT, W2 = 1 MBT, W3 = 1 MST, W4 = 2 MST. The parameters observed were: Plant Height (cm), Number of Cloves (tubers), Wet Weight per Plot (g), Dry Weight per Plot (g), Wet Plant Weight Sample (g), and Dry Weight of Sample Plant (g). The results showed that various doses and time of application of bio-organic fertilizer independently affected the growth of 8 MST onion height, number of cloves, plots plant wet weight, plots plant dry weight, plots plant wet weight, sample plant dry weight. The interaction of the effects of various doses with the time of application of bio-organic fertilizer did not affect all observed parameters.
