<![CDATA[This study aims to see the effect of chicken coop and NPK pearls on the growth and yield of purple sweet potato (Ipomoea batatasL). This study was started in August - November 2020, located on Ikip Mekarsari Street, Tenggarong District, Kutai Kartanegara Regency, East Kalimantan Province. The research was arranged in a factorial Randomized Complete Block Design (RCBD) consisting of 2 factors and repeated 3 times. The first factor is the provision of chicken manure (p) which consists of 3 levels, namely p0 (without treatment), p1 (20 t ha-1), p2 (40 t ha-1). And the second factor is the pearl NPK fertilizer (n) which consists of 3 levels, namely n0 (without treatment), n1 (300 Kg ha-1), n2 (600 Kg ha-1). The results showed that chicken manure had no significant effect on all observed parameters. The highest average yield of plants t ha-1 is the treatment p2 (40 t ha-1) 26,58 t ha-1. while for the lowest treatment with an average of 25,46 t ha-1, namely the p1 treatment (20 t ha-1). The results showed that NPK fertilizer had no significant effect on all observed parameters. The highest average yield of plants t ha-1 was at treatment n2 (600 Kg ha-1) 26,11 t ha-1, while for the lowest treatment with an average of 25,68 t ha-1, namely treatment n1 (300 Kg ) ha-1). The results of the interaction between chicken manure and NPK fertilizer did not significantly affect all parameters. The highest average yield of t ha-1 was the p2n2 treatment with a yield of 26,90 t ha-1. And the lowest average yield of t ha-1 is the p1n1 treatment with a yield of 24,73 t ha-1.]]>
