Pemberian Biourin Sapi dan Pupuk Fosfor terhadap Pertumbuhan dan Produksi Tanaman Jagung Manis (Zea mays saccharata Sturt.)
The need for sweet corn increases along with the increase in population. Increasing corn production can be done by using cow biourine and phosphorus fertilizer. This research aims to determine the interaction and combination of giving cow biourine with phosphorus fertilizer on the growth and yield of sweet corn plants. This research used a completely randomized design (CRD) consisting of two factors. The first factor is the provision of cow biourine which consists of 4 levels, namely without cow biourine (B0), 50 ml per plant (B1), 100 ml per plant (B2) and 150 ml per plant (B3). The second factor is the provision of phosphorus fertilizer which consists of 4 levels, namely without phosphorus fertilizer (F0), 100 kg.ha-1 (F1), 150 kg.ha-1 (F2) and 200 kg.ha-1 (F3). The two factors were obtained in 16 combinations and repeated 3 times to produce 48 experimental units. Observation parameters were plant height, number of leaves, stem diameter, flower appearance time, harvest age, weight of cornhusk cobs, weight of cobs without cornhusk and production amount. The data obtained were analyzed statistically with analysis of variance and Duncan's multiple range test (DNMRT) at the 5% level using SAS version 9.1. The results of the research showed that giving 150 ml of cow biourine per plant and 200 kg ha-1 of phosphorus fertilizer significantly increased plant height, number of leaves, flowering age, stem diameter, harvest time, weight of cobs with cornhusk, weight of cobs without cornhusk and corn production.
Keyswords: cow biourine, phosphorus fertilizer, sweet corn
