The effect of mychorrizal dose interactions with varieties on growth and yield of chili (Capsicum annum L.) in andisol soil Bener Meriah

Abstract

This study aims to determine the interaction of mycorrhizal doses and varieties on the growth and yield of chili plants in Andisol soil. This research was conducted in Blang Kucak Village, Wih Pesam District, Bener Meriah Regency, Green House and Laboratory of Plant Physiology, Faculty of Agriculture, Syiah Kuala Darussalam University, Banda Aceh from January to May 2019. Analysis of the data used in this study was Randomized Block Design, with 3 x 2 factorial pattern with 3 replications. There are 2 series in this experiment namely Series A and Series B, series A is used for data collection of growth and yield of chili plants, while series B is used for data collection of mycorrhizal colonization. The factors observed in this study were mixed mycorrhizal bio-fertilizers and varieties. The dose of mycorrhizal bio-fertilizer used was control (without mycorrhizal), 5 g plant−1 and 10 g plant−1 and the varieties used were varieties of PM-999 and Perintis. The results showed a very significant interaction between mycorrhizal doses and varieties on the parameters of the number of productive branches, besides that there were significant interactions on plant height at 45 DAP, fruit weight, fruit length, number of fruits and yield potential (tons ha−1). The best combination was found in the treatment of doses of 10 g mycorrhizal plants−1 and Perintis varieties.
