PENGARUH INOKULASI MIKORIZA, KOTORAN WALET DAN PEMUPUKAN PHOSPHAT TERHADAP PERTUMBUHAN DAN HASIL TANAMAN JAGUNG MANIS (Zea mays L. Saccharata) DI TANAH PASIR
Abstract
This reasearch aims to comprehend the reaction of VMA inoculation and swallow dung on the growth of sweet corn on the sand field. It also aims to obtain the best and the most appropriate Phosphorus Fertilizer of all treatment toward the growth of sweet corn in the beach sand. This research is conducted on January–September of 2017 in the Green House, Laboratorium of Agrobiotechnology and Research Laboratorium of Faculty of Agriculture, UMY.
This research is conducted with the design of compiled single factor Completely Randomized Design (CRD) and consist of 5 treatments such as : Fertilizer SP-36 100% of recommended dosage + MVA (A). Fertilizer SP-36 75% of recommended dosage + swallow dung 25% + MVA (B), Fertilizer SP-35 75% of recommended dosage, swallow dung 25% (C), Fertilizer SP-36 50% of recommended dosage, swallow dung 50%. The observed parameters were the number of mychorrhizal spores, infection percentage, isolation and identification of bacterial solvent phosphat, root length, fresh root length, dry root weight, plant height, leaf number, leaf area, fresh plant weight, dry plant of weight, number of rows per cob, diameter of cob, dry weight of plant, fresh weight of cobs weighted, uneconomical weight of cob and potential of crop.
The research result showed that the application of fertilizer SP-36 75% and swallow dung 25% in th sweet corn gave the best result of the leaf number and economical weight of cob in the coastal area.
