Potential of liquid organic fertilizer from horse and cow urine on shoot growth of Cattleya labiata Lindl.

Abstract Liquid organic waste from animals can be fermented into liquid organic fertilizer, so it can be an alternative to increase plant growth. This study aims to determine the effect of giving horse and cow urine LOF, as well as its interaction on shoot growth in the Cattleya labiata Lindl orchid plant. The method used is a factorial experimental method with a randomized block design and three replications. Liquid organic fertilizer from horse and cow urine with a concentration of 0%, 10% and 20%. There were 9 treatment combinations with 27 experimental units. The results showed that the LOF application of horse and cow urine and their interactions had a very significant effect on the growth of Cattleya labiata shoot diameter in the 4th week. The application of horse urine LOF and its interaction with cow urine LOF had no significant effect on the growth of the number and height of shoots, but had a very significant effect on the administration of cow urine LOF. The best treatment was found in the application of 20% cow urine LOF without horse urine LOF (K0S2); obtained the highest growth of one shoot 4.8 cm with the highest diameter of 1.8 cm. LOF application of cow urine is more effective in increasing the growth of orchid shoots including: number, height, and diameter of shoots.
