The Increase of Forage Productivity in Ex Coal Mining by Adding Fertilizer and Forage in East Kalimantan

Nur Rizqi Bariroh, Darniati Danial, SG Gunawan


East Kalimantan has many minerals that contribute 47.44% of province income. However, coal mining exploitation resulting poor quality of soil. One effort to recover this condition is by planting a right forage combined with fertilization. This study aimed to know forage productivity in ex coal mining with various fertilizations and forage combinations. This study was conducted in Petangis village, Paser district, East Kalimantan. Research method was Factorial Randomized Block Design. Factor 1 was forage combination, whereas (a) Brachiaria humidicola + centrosema pubescens and (b) Brachiaria humidicola + Stylosanthes guyanensis. Factor 2 was fertilization, whereas (a) control (b) manure (c) manure + lime (d) manure + urea (e) manure + lime + urea. All treatments were replicated three times. Area of each plot was 100 m2. Grass and legume were planted separately in the same plot. Parameters measured were forage height and forage production. Forage height was at the age of 30 days after planting in two seasons. Forage production was the total production of two forages in the same plot. Statistical analysis was performed using SAS portable 9.0. ANOVA was carried out to compare the difference of means. If there was a significant result, it was followed by Duncan test. The result shows that combination between Brachiaria humidicola + Centrosema pubescens and manure + urea was a significant result (P<0.01). The production of this treatment was 9.6 higher than other treatments
