Abstract


ABSTRACT

Potatoes (Solanum tuberosum, L.) are one of the important food commodities after rice, maize
and wheat whose needs continue to increase both to meet domestic needs and even have the potential to be
exported. This study aims to determine the effect of NPK fertilizer, Liquid Organic Fertilizer, and
Trichocompost on the growth and production of potato (Solanum tuberosum L.). This study used a
literature study method, utilizing the results of research and scientific publications on the effect of NPK
fertilization, Liquid Organic Fertilizer, and Trichocompost on the growth and production of potato plants.
The results showed that the application of NPK fertilizer, Liquid Organic Fertilizer, and Trichokompos
had an effect on the growth and production of potato (Solanum tuberosum L.). The dose of NPK fertilizer
given to potato plants was 700 - 1,400 kg and could be combined with manure, with production 14.7 -22.5
ton ha-1
. The dose of liquid organic fertilizer can be given 5-25 ml / liter of water and can produce potato
production 23.13 - 34.56 ton ha-1

. Tricho-compost biofertilizer can be given in solid form 25 ton ha-1 or in
liquid form 5 ml / l -250 ml / l can be sprayed onto leaves or onto the soil, and can give potato production
36.8 - 38.3 ton ha-1

. Tricho-compost can help suppress and control the attack of soil-borne pathogens such
as Fusarium fungi, Phytophora fungi, and Phytium fungi which are important pathogens in potato
cultivation..
