The optimization of oil quality in sunflower seeds (Heliantus annuus L.) by giving cow manure and EM4

Abstract

Sunflower as a source of oil that is consumed as a provider of high quality protein. Sunflowers play an important role in nutrition for humans. This study aims to examine the optimization of oil quality in sunflower seeds (Heliantus annuus L.) by providing cow manure and EM4 to obtain recommendations for developing cultivation technology engineering formulas to improve oil quality. This study used a Randomized Completely Block Design method consisting of 2 treatments and each treatment was repeated 3 times. The first factor for manure dosing, consists of 4 levels, there are: N0: 0 ton ha-1; N1 : 10 ton ha-1; N2 : 15 ton ha-1; N3: 20 ton ha-1. The second factor is concentration of EM4, consists of 4 levels, there are: D0: EM4 0 cc/lt-1; D1: EM4 15 cc/lt-1; D2 : EM4 30 cc lt-1; D3 : EM4 45 cc lt-1. The variables of this research were: seed weight per plant and per plot, and quality of oil content of sun flower seeds. The results of analysis of variance on the variable seed weight of each plant and per plot showed the interaction between treatments with the best treatment combination was N1D2 (manure dosage of 10 tons ha-1, EM4 concentration of 30 cc lt-1). In the observation parameters, the sunflower seed oil content also has interactions between treatments with the best treatment combination is N2D3 (manure dosage of 20 tons ha-1, EM4 concentration of 45 cc lt-1).
