Abstract

The purpose of this study was to determine the productivity of elephant grass (Pennisetum purpureum) planted with leguminosae at various doses of bioorganic fertilizers. This study used a completely randomized design with two factorial patterns. The first factor was the type of leguminosae (T= without leguminosae; R= Arachi pintoi; L= Alysicarpus vaginalis; and the second factor was the dose of bioorganic fertilizer (D0= 0 kg Nha-1; D1= 100 kg Nha-1; D2= 200 kg Nha-1; and D3= 300 kg Nha-1) There were 12 treatment combinations, each treatment was repeated 5 times so that it consisted of 60 experimental units. The observed variables included growth, yield and growth characteristics variable. The results showed that there was no interaction between leguminous species and fertilizer dosage, both leguminous species only increased leaf area per pot, bioorganic fertilizer D1 and D2 doses tended to increase, while D3 dose increased leaf dry weight, total forage dry weight, and leaf area per pot of elep- hant grass (Pennisetum purpureum). It was concluded that the type of leguminous did not affect the productivity of elephant grass, the dose of bioorganic fertilizer increased crop yields, the highest yields at a dose of 300 kg Nha-1 bioorganic fertilizer.

Abstract

The research aims to obtain a dose of NPK fertilizer substituted for cow biourine that can produce the best productivity of Asystasia gangetica (L.) subsp. Micrantha, used a completely randomized design consisting of 9 tre- atments repeated 7 times, so there were 63 experimental units. Treatments consisted of D0: no fertilizer, D1: NPK 200 kg ha-1, D2: Cow biourine (CB) 5,000 l ha-1, D3: CB 7,500 l ha-1, D4: CB 10,000 l ha-1, D5: NPK 50 kgha-1 + CB 5,000 l ha-1, D6 : NPK 50 kgha-1 + CB 7,500 l ha-1, D7 : NPK 100 kgha-1 + CB 5,000 l ha-1, and D8 : NPK 100 kgha-1 + CB 7,500 l ha-1. The results showed that Asystasia gangetica that received the D5 treatment produced a higher number of leaves, leaf dry weight, stem dry weight, and total forage dry weight compared to D0 and the same as the D1 treatment. It was concluded that Asystasia gangetica (l.) subsp. Micrantha that received D5 fertilizer treatment (NPK 50 kgha-1 + cow biourine 5,000 l ha-1) showed better growth and yield compared to without fertilizer and the same as D1 treatment (NPK 200 kg ha-1).
