Application of Chitosan-AA-PMAA-NPK Micro-fertilizers on Germination of Swamp Jelutung (Dyera polyphylla (Miq.) Steenis) and Paddy (Oryza sativa L.)

Abstract

Degradasi dan deforestasi lahan gambut menyebabkan kerusakan ekologis. Rehabilitasi dan restorasi lahan gambut dapat dipercepat dengan aplikasi pupuk dan penanaman spesies adaptif. Jelutung rawa dan padi Inpara-2 merupakan spesies yang adaptif di lahan gambut. Penelitian ini bertujuan membuat formula Chitosan-AAPMAA-NPK Micro-fertilizers dan menganalisis aplikasinya terhadap pertumbuhan jelutung rawa dan padi. Rancangan yang digunakan adalah Rancangan Acak Lengkap dengan 1 faktor (Micro-fertilizers), 18 taraf, dan empat ulangan pada setiap spesies. Aplikasi Chitosan-AA-PMAA-NPK Micro-fertilizers pada jelutung rawa berpengaruh nyata terhadap daya kecambah, laju kecambah, persen hidup semai, tinggi semai, berat basah semai, berat kering semai, dan jumlah akar semai. Aplikasi Micro-fertilizers tersebut pada padi menunjukkan pengaruh nyata terhadap daya kecambah, persen kecambah normal, potensi tumbuh maksimum, laju kecambah, persen hidup semai, tinggi semai, berat basah semai, berat kering semai, dan jumlah akar. Perlakuan activated micro-carbon (MT) 5% menghasilkan pertumbuhan terbaik pada jelutung rawa, sedangkan perlakuan micro-crystalline cellulose (MK) 3% menghasilkan pertumbuhan terbaik pada padi.

Peatland degradation and deforestation have led to ecological damage. Peatland rehabilitation and restoration could be accelerated by planting adaptive species and fertilizers application. Swamp jelutung and paddy Inpara-2 varieties are the adaptive species in peatland. This research aims to formulate the chitosan-AA-PMAA-NPK micro-fertilizers and analyze the application on germination of swamp jelutung and paddy. The experimental design used a completely randomized design with a factor (micro-fertilizers), 18 levels, and four replications at each species. The chitosan-AA-PMAA-NPK micro-fertilizers application significantly affects the germination percentage, mean germination time, seedling survival rate, seedling height, seedlings wet weight, seedlings dry weight, and seedling root number of swamp jelutung. The micro-fertilizers application on paddy were significantly affects the germination percentage, abnormal sprout percentage, maximum growth potential, mean germination time, seedling survival rate, seedling height, seedlings wet weight, seedling dry weight, and seedling root number. Application of the activated micro-carbon (MT) 5% treatment resulted in the best growth on swamp jelutung, while the micro-crystalline cellulose (MK) 3% treatment resulted in the best growth on paddy.
