Abstract

Tanaman Jagung (Zea mays L.) Varietas Pulut merupakan varietas jagung lokal dengan potensi hasil rendah, yaitu kurang dari 2 ton ha-1. Tujuan penelitian ini yaitu mengetahui pengaruh jenis tanah dan menentukan jenis tanah yang paling sesuai terhadap pertumbuhan dan hasil tanaman jagung (Zea mays L.) Varietas Pulut. Metode penelitian yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan faktor tunggal dan terdiri dari 4 perlakuan yaitu tanaman jagung varietas pulut yang ditanam pada tanah Regosol bukit-pasir, tanah Grumusol, tanah Latosol, dan tanah Mediteran. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, panjang akar, bobot segar akar, bobot kering akar, luas daun, bobot segar tajuk, bobot kering tajuk, laju asimilasi bersih, laju pertumbuhan tanaman, bobot tongkol dengan klobot, bobot tongkol tanpa klobot, diameter tongkol, panjang tongkol, jumlah baris biji, bobot 1000 biji, potensi hasil tanaman. Hasil penelitian menunjukkan perlakuan jenis tanah memberikan potensi hasil pada perlakuan tanah Regosol bukit-pasir sebesar 2,6 ton ha-1, tanah Latosol sebesar 2,46 ton ha-1, tanah Grumusol sebesar 2,05 ton ha-1, dan tanah Mediteran sebesar 2,04 ton ha-1. Berbagai jenis tanah cenderung memberikan hasil yang relatif sama, sehingga berbagai jenis tanah dikatakan sesuai dalam pertumbuhan dan hasil tanaman jagung varietas pulut.

Abstract

Indonesian soybean production could not reach national needs. Thus to increasing of soybean productivity could be developed by using agricultural intensification through implementing nano technology on fertilizers that applied to new varieties of soybean. The aim of this research was to study the effect and determine the appropriate concentration of nano phosphate fertilizer from chicken bone ash via foliar application on growth and yield on soybean (Glycine max L.) variety Dega 1. This research was conducted with experimental method in polybag with a single factor treatment arranged in a Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications: 100 % SP-36 fertilizer , 50% SP-36 fertilizer SP-36 + 0,1% nano phosphate, 50% SP-36 fertilizer +0,2% nano phosphate, dan 50% SP-36 fertilizer +0,3 % nano phosphate. Data research consists of growth and yield responses parameters and were analyzed by using ANOVA (Analysis of Variance) then continue analyzed with Duncan Multiple Range Test (DMRT) at α level 5%. The results revealed that various concentrations of nano phosphate fertilizer from chicken bone ash were effective to increase soybean growth and yield. Treatment of 50% SP-36 + 0,1% of nano phosphate choosen as best concentration.
