Abstract

THE EFFECT OF UREA FERTILIZER ON THE GROWTH OF SPINACH (Amaranthus Tricolor L.) in RICE SOILS IN RANOKETANG ATAS VILLAGE

This study aims to determine the effect of urea fertilizer on the growth of spinach plants in rice soils. This research was conducted in Ranoketang Atas Village, Touluaan District, Southeast Minahasa Regency. This experiment used a completely randomized design (CRD) consisting of one factor with 4 treatments of urea fertilizer doses and repeated 3 times, so there were 12 total trials. The treatment given was a dose of urea fertilizer, which consisted of 4 treatments, namely, P0= Control, P1= 100kg Urea/ha, P2= 200kg Urea/ha and P3= 300 kg Urea/ha. Observed variables included plant height, number of leaves and plant fresh weight. The data obtained were analyzed using analysis of variance with Completely Randomized Design (CRD) if there was a significant (significant) difference, it would be continued with the smallest significant difference test (BNT) at 5% level. The effect of urea fertilizer on the growth of spinach plants did not significantly affect this treatment based on the results of analysis of variance but in the treatment of urea fertilizer there was an increase in plant growth. Spinach plant height growth had the highest value in the P2 treatment (200 Kg/ha) after P0 (control). The highest number of leaves was found at P0 (control) after that in the treatment of P2 fertilizer (200 Kg/ha). And the good fresh weight of spinach plants was found in the P2 treatment (200 Kg/ha).
