Abstract

Stem rot or foot rot disease caused by Phytophthora capsici is known as an important constraint on pepper cultivation. Research was conducted to determine the effect of arbuskula mycorhizal fungi (AMF) on incidence of foot rot disease of pepper seedlings.  The experiment was done in the net house and arranged using completed randomized design with 6 treatments, i.e. (1) soil infested by P. capsici (TPC) as negative control treatment, (2) sterilized soil (TS) as positive control treatment, (3) TPC with 5 g of AMF, (4) TPC with 10 g AMF, (5) TPC with 15 g AMF, and (6) TPC with 20 g AMF.   Observation involved plant height, number of shoots, disease incidence, the percentage of AMF infection on the roots of pepper plants, and pepper plants dependence on AMF. The results showed that the application of AMF at a dose of 20 g per 10 kg of soil effectively suppressed incidence of foot rot disease and improve plant growth

Abstract

This study aims to determine the effect of local arbuscular mycorrhizal fungi (AMF) on weed density, growth and yield of sweet corn in marginal soils. This study used a randomized block design with local AMF propagules which consisted of 4 levels: 0 g/planting hole or control (A0), 15 g/planting hole (A1), 30 g/planting hole (A2) and 45 g/planting hole (A3). The research parameters observed were: weed density, plant height, stem diameter, crop yield, and the percentage of AMF infection in the roots of corn plants. The results showed that the highest weed dominance value at the age of 14 DAP was Cyperus rotundus as 36.8% in treatment of AMF 45 g/planting hole (A3), age 56 DAP the highest weed dominance value was Hyptis capitata as 47.1% in the treatment of AMF 30 g/planting hole. The best plant height and stem diameter were found in the treatment of AMF 45 g/planting holes (A3) at 56 DAP, the average plant height reached 234.05 cm and the average stem diameter reached 3.72 cm. Increased production of corn plants that were given local AMF ranged from 2.70 to 3.10 tons ha-1 or an average increase in overall corn crop production of 2.86 tons ha-1. The average percentage of mycorrhiza fungi infections in the highest roots of corn plants in the treatment of AMF 45 g/planting hole (A3) as 94%.   Key words: Arbuscular mycorrhiza fungi; vesicles; hypha; maize; ultisols
