Abstract
This study aims to see the growth and yield of hybrid red chili with various varieties and the dose of NPK Mutiara fertilizer and to see the interaction between hybrid red chili varieties and the dose of NPK Mutiara fertilizer. This study used a factorial randomized block design (RAK) consisting of 2 factors, namely the red chili variety factor (V) which consisted of 3 types: V1 = Kastilo F1, V2 = Laju F1, and V3 = Lado F1. The combination factor of NPK fertilizer (P) consisted of 3 levels: P1 = 19 g/plant, P2 = 23 g/plant, and P3 = 28 g/plant. Parameters observed included flowering age (Days), stem diameter (cm), number of chilies per plant (fruit), chili length (cm), chili diameter (cm), fresh chili weight per plant (gr), and fresh fruit weight. per plot (gr). The results showed that hybrid red chili varieties had a significant effect on the parameters of the number of chilies per plant, the weight of fresh chilies per plant, and the weight of fresh chilies per plot. The best results were obtained in the V2 treatment (F1 Laju). The dose of NPK Mutiara had a significant effect on the parameters of flowering age and chili length. The best results were obtained in the P3 treatment (28 g/plant). The interaction of hybrid red chili varieties with NPK Mutiara fertilizer had a significant effect on chili length parameters and the number of chili peppers per plant. However, it had no significant effect on flowering age, stem diameter, chili diameter, fresh chili weight per plant, and fresh chili weight per plot. The best interaction was found in the V2P3 treatment (F1 rate + 28 g/plant).

Pengaruh aplikasi pupuk hayati terhadap pertumbuhan dan produktivitas tanaman cabai rawit (Capsicum frutescens L.) varietas Bhaskara di PT Petrokimia Gresik
Summary
Hasil uji F pada analisis ragam menunjukkan bahwa umur berbunga tidak berpengaruh nyata terhadap perlakuan varietas namun berpengaruh nyata akibat perlakuan pupuk NPK Mutiara. Hal ini diduga ketersediaan unsur hara dalam tanah relatif rendah sehingga tidak menunjukkan pengaruh yang nyata terhadap diameter batang cabai. Hal ini diduga pemberian pupuk NPK Mutiara dapat meningkatkan ketersediaan unsur hara N, P dan K dalam tanah khususnya peranan unsur P yang sangat dibutuhkan tanaman untuk mempercepat pembungaan. Hal ini diduga karena tingkat curah hujan yang tinggi menyebabkan terjadinya pencucian terhadap unsur hara dalam tanah dan pupuk yang diaplikasikan terhadap tanaman sehingga mempengaruhi terhadap hasil tanaman cabai. Hal ini sesuai dengan pendapat Setiawan, (2016) yang menyatakan bahwa curah hujan yang tinggi dapat menyebabkan unsur hara dalam tanah terbawa oleh air hujan dan tidak dapat diserap oleh akar secara optimal sehingga mempengaruhi pertumbuhan dan hasil produksi tanaman.
