Effectiveness of Mycorrhiza and Phosphorus of Phosphate Rock on Growth and Yield of Eggplant (Solanum melongena L.) | Efektivitas Mikoriza dan Fosfor dari Batuan Fosfat pada Pertumbuhan dan Hasil Terong Ungu (Solanum melongena L.)

Indonesian. Dalam percobaan ini dilakukan penelitian pengaruh pupuk hayati mikoriza dan batuan fosfat terhadap pertumbuhan dan hasil tanaman terong (Solanum melongena L.) dengan takaran pupuk yang berbeda. Pupuk hayati mikoriza diberikan ke tanah sebesar 0, 10, dan 20 g per lubang tanam, sementara batuan fosfat yang telah dihaluskan diberikan ke tanah sebesar 0, 45, dan 90 kg P2O5/ha. Interaksi antara mikoriza dan batuan fosfat nyata meningkatkan tinggi tanaman terong, bobot rata-rata terong per buah, dan hasil terong  dibandingkan dengan tanpa pemberian pupuk. Aplikasi mikoriza nyata meningkatkan tinggi tanaman terong dan bobot rata-rata terong per buah, sedangkan aplikasi batuan fosfat hanya nyata memengaruhi tinggi tanaman terong. Pada perlakuan tanpa batuan fosfat dengan takaran dua kali mikoriza menunjukkan bahwa bobot rata-rata terong per buah nyata lebih tinggi daripada tanpa aplikasi mikoriza. Hal ini menunjukkan bahwa mikoriza mempunyai pengaruh positif terhadap pertumbuhan dan hasil terong dan pada ketersediaan fosfor bagi tanaman terong.

English. In this study, effect of biofertilizer of mycorrhiza and phosphate rock on growth and yield of eggplant (Solanum melongena L.) under different fertilization rates had investigated. Biofertilizer of mycorrhiza were applied to soil as 0, 10, and 20 g per planting hole, meanwhile grinded phosphate rock were added into soil as 0, 45, and 90 kg P2O5 ha-1.  Interaction between mycorrhiza and phosphate rock significantly increased the height of eggplant, average weight of an eggplant, and eggplant yield compared to no fertilization treatment. Mycorrhiza application significantly increased the height of eggplant and the average weight of an eggplant, whereas phosphate rock application affected significantly only on the height of eggplant. In the treatment at 0 doses of phosphate rock with double doses of mycorrhiza showed that the average weight of an eggplant were significantly higher than without mycorrhiza application.  It was determined that mycorrhiza had positive effect on growth and yield of eggplant and phosphorus bioavailability to eggplant.
