| dc.description.abstract | Pakcoy is one type of green vegetable that is still in the same family as mustard
greens. The growth of vegetable plants can be increased by applying biofertilizers,
biofertilizers contain Plant Growth Promoting Rhizobacteria (PGPR) which is a
class of bacteria that live and develop well in soil rich in organic matter, these
bacteria actively colonize the root area of plants, have an important role for plants,
namely: As a biofertilizer PGPR is able to accelerate the process of plant growth
through accelerated absorption of nutrients, as a biostimulant PGPR can spur plant
growth through the production of phytohormones and as a bioprotectant PGPR
protects plants from pathogens. This study aims to determine the growth and
production response of pakcoy plants to different doses and fertilization times of
liquid biological fertilizer. This research will be conducted from July to August
2023. This study used a factorial Randomized Group Design (RAK) consisting of 3
replicates with 2 treatment factors. Factor I Dosage of Liquid Biofertilizer: 10 L/ha,
20 L/ha, 30 L/ha. Factor II Application Time: 7 days after transplanting, 10 days
after transplanting. Based on the research that has been done, it is found that the
application of liquid biological fertilizer has a significant effect on increasing plant
height, stem diameter, total leaf area, crown fresh weight, crown dry weight, root
fresh weight, root dry weight, and biomass weight, by giving a dose of liquid
biological fertilizer of 20 L/ha to increase the best growth and production with
application time can be used at any time in the vegetative phase of pakcoy plants
recommended at 7 days after transplanting. | en_US |
