Chicken manure and biofertilizer for increasing growth and yield of potato (Solanum tuberosum l.) of Granola varieties

Abstract

The experiment aimed to assess the characteristics of growth and yield of potato due to the application of chicken manure and biofertilizer was conducted. The research began on from February until June 2018, in Pangalengan The experiment arranged as factorialized randomized block design, consisted two factor with three replications. Cchicken manure dosage (k1 = 5 ton ha−1, k2 = 10 ton ha−1, k3= 15 ton ha−1 ) and Biofertilizer concentrate (h1 = 2,5 mL L−1, h2 = 5,0 mL L−1, h3= 7,5 mL L−1). The measured parameters were the growth (plant height, number of stem, number of leaf) and yield of potatoes (weight number of tuber, weight of tuber per plot, number of tuber per plant, weight of tuber, potato weight classification). The result showed that the interactions between the chicken manure dosage and biofertilizer concentrate affected the number of potato tubers per plant, weight of potato tubers per plant, and potato yield per plot. The highest yield (55.30 kg per plot) was obtained by combination k2h3 (chicken manure dosage 10 ton ha−1 and biofertilizer concentre 7,5 mL L−1). These findings concluded that the chicken manure combined with biofertilizers could be applied to increase the growth and productivity of potatoes.
