Abstract

This study aimed to examine the effect of different concentrations of biofertilizer and NPK fertilizer dosages on the growth and yield of lettuce (Lactuca sativa L.). The research was conducted at the Experimental Field of BPP Cilimus, Kuningan, West Java, from June to July 2023 using a Randomized Block Design (RBD) with two treatment factors: biofertilizer concentration (5 ml/L, 10 ml/L, and 15 ml/L) and NPK fertilizer dosage (100 kg/ha, 150 kg/ha, and 200 kg/ha). The combination of treatments resulted in nine treatment levels, each replicated three times, yielding a total of 27 experimental units. The main parameters observed included plant height, number of leaves, leaf width, stem diameter, root volume, root length, and plant fresh weight. The results showed that the treatment combination significantly affected the number of leaves per plant, but had no significant effect on plant height. The best treatment was obtained from the application of 10 ml/L biofertilizer combined with 100 kg/ha NPK fertilizer, which produced the highest average number of leaves (17.93 leaves). Thus, the proper combination of biofertilizer and NPK fertilizer can improve the vegetative growth of lettuce and may serve as an alternative strategy for farmers to enhance lettuce productivity.
