Improvement in yield of peanut (Arachis hypogaea L.) with combination treatments of bio-organic fertilizers

Abstract

Peanut is a plant food with high economic value because of their nutritional content, especially protein, and high fat. The nut land needs from year to year continue to increase in line with the increase in number population, nutritional needs of the community, food diversification, and increasing feed and food industry capacity. The present study aimed to determine the effectiveness of bio-organic fertilizers in producing local peanuts (Wadaga) from Muna Island, Indonesia. The randomized block design (RBD) was done with 12 bio-organic fertilizer treatments (T1 to T12) based on arbuscular mycorrhiza fungi (AMF) and cow manure fertilizer (CMF). The variables were viz. pod weight, total pod number, filled pod number, percentage of empty pods, seed number, the weight of 100 seeds, dry seed weight, and productivity were observed. The results of the study showed that the highest average pod weight (55.0 g), total pod number (50.3 pods), filled pod number (46.3 pods), and seed number (84.3 seeds) occurred with the treatment of T8: A2 B1 (AMF 10 g per plant + CMF 3 kg per plot). The highest average productivity was obtained with T3: A0 B2 (without AMF + CMF 6 kg per plot) as 3.97 tons ha-1 . The use of mycorrhizal fungi combined with organic fertilizers can improve the growth of peanut plants which has a positive impact on their production.
