Pemupukan terpadu organik dan anorganik pada budidaya tanaman kacang panjang (Vigna Sinensis L)
Integrated fertilization is an alternative to increase soil and plant productivity on marginal lands. The integrated fertilization principle is to combine and apply inorganic and organic fertilizers simultaneously, aiming to add nutrients into the soil and improve soil propoerties. This study aimed to determine the composition of integrated organic and inorganic fertilizers for the best growth and yield of asparagus bean. This experimental research was carried out in the field using a randomized block design (RAK), consisting of the following seven treatments: T0 (Without fertilizer), T1 (Chicken manure fertilizer), T2 (Shrimp waste), T3 (Chicken manure+urea+TSP+KCL), T4 (Cicken manure+phonska), T5 (Shrimp waste fertilizer+Urea+TSP+KCL) and T6 (Shrimp waste fertilizer+phonska). The parameters observed were plant height, stem diameter, flowering age, pod length, and pod weight. The data obtained were analyzed using an F test, and for data influenced by the treatment were then tested at BNT level 5%. The results showed that the application of integrated organic and inorganic fertilizers treatment only affected plant height at 2 WAP and pod length, while no effect was found in any other parameters. Despite statistically no significant effect, in general, integrated inorganic and organic fertilization with shrimp waste+urea+TSP+KCL (T5) presented the best asparagus bean pod weight compared to the other treatments with a value of 143.7 gr.
