Abstract

Keterbatasan lahan potensial menyebabkan perluasan areal pertanian mengarah pada lahan gambut. Kendala pengembangan lahan gambut adalah rendahnya kandungan hara tersedia bagi tanaman. Fosfat (P) merupakan salah satu unsur hara makro yang penting untuk pertumbuhan dan produksi tanaman, disisi lain ketersediaan hara ini pada lahan gambut terbatas karena ikatan asam organik dan sifat yang mudah tercuci. Penelitian untuk menguji pengaruh ameliorasi dan inokulasi mikroba pelarut fosfat terhadap ketersediaan hara P di lahan gambut dilakukan di kebun pembibitan kelapa sawit petani di Riau dari Oktober 2013 - Maret 2014, menggunakan Rancangan Acak Kelompok pola Faktorial dengan 30 kombinasi perlakuan dan 3 kali ulangan. Variabel yang diamati meliputi: tinggi tanaman, lingkar batang, jumlah daun, lebar daun, panjang daun, kandungan hara tanaman, dan bobot biomasa bibit setelah 5 bulan di pembibitan. Hasil penelitian menunjukkan bahwa ameliorasi menggunakan kompos tandan kosong kelapa sawit mampu meningkatkan P tersedia, serapan P oleh batang dan akar, berat brangkasan dan berat kering batang. Sedangkan mikroba pelarut fosfat berpengaruh secara tidak nyata.The limitation of potential land leads agricultural development expansion to the peat soil area. Constrain of the peatland development is the low nutrient content that is required by plant. Phosphate is one of major growth and production limiting nutrient because of the solublelize of the organic acids and immobility The research was conducted from October 2013 – March 2014 at the farmer main nursery in Riau province to test the effect of amelioration and phosphate solubilizing microbe inoculation on P availability on palm oil seedling growth and production at peatland, used Randomized Block Design with 30 treatments and 3 replications. The parameters observed were plant height, leaf number, leaf width, leaf length, stem diameters, nutrient contents, also fresh and dry weight after 5 months at the main nursery. The result showed that palm oil empty fruit bunch compost as ameliorant increased P nutrient avaibility, P uptake, fresh and dry weight, whereas phosphate solubilizing microbe was unsignificant.
