The main purpose of this paper is to evaluate the effect of crude oil price on global fertilizer prices in both the mean and volatility. The endogenous structural breakpoint unit root test, ARDL model, and alternative volatility models, including GARCH, EGARCH, and GJR models, are used to investigate the relationship between crude oil price and six global fertilizer prices. The empirical result...

The main purpose of this paper is to estimate the volatility in global fertilizer prices. The endogenous structural breakpoint unit root test and alternative volatility models, including the generalized autoregressive conditional heteroskedasticity (GARCH) model, Exponential GARCH (EGARCH) model, and GJR model are estimated for six global fertilizer prices and the crude oil price. Weekly data f...

Abstract Background : Suicide is a complex phenomenon determined by the interaction of various risk factors. The Major Histocompatibility Complex most polymorphic gene cluster entire human genome, being linked to both regulation immune system and psychiatric diseases. aim this study was identify HLA-DQB1 DRB1 alleles genotypes susceptible influence suicidal behavior. Methods We explored associa...

The present study aims to determine the optimal dose of ox dung and sowing density that optimize yield seed cotton in region BERE North-West Côte d'Ivoire. Six fertilizer doses (T0, T1, T2, T3, T4 T5) were tested. Among these six doses, T3 are composed a mixture NPK mineral fertilizer, T0 is T5 only cattle dung. These tested on plants through 4 seeding densities : low (LowD 50 cm x 80 with 2 pl...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 4. The 4-year average for the different fertilizer backgrounds indicated that the least total grain damage by cereal bug larvae was in the block with organic-mineral fertilizer, 5.6 %. Damage in the blocks without fertilizer and with only organic fertilizer was 5.9 and 6.0 %, respectively. Total damage was 4.2–4.9 % in seed with a score of 2, w...
