Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk anorganik dan pupuk organik diperkaya N, P organik terhadap penyerapan unsur hara tanaman selada. Penelitian ini menggunakan RAL monofaktor yang terdiri dari 9 perlakuan dengan 3 ulangan. Perlakuan pupuk yaitu urea (T1), TSP (T2), urea + TSP (T4), Pupuk kandang (pukan) (T4), Pukan + gamal (T5), Pupuk kandang + BP (T6), pukan + guano(T7), Pukan + BP + gamal (T8), dan pukan + guano + gamal (T9). Perlakuan diulang sebanyak 3 kali. Parameter yang diamati adalah berat kering, rasio tajuk akar, serapan nitrogen, dan serapan fosfor. Data analisis ragam dilanjutkan uji duncan menunjukan pupuk organik mampu meningkatkan separan hara tanaman setara pupuk anorganik. Perlakuan yang diberikan pada parameter rasio tajuk akar tertinggi didapat pada perlakuan T5. Sedangkan, parameter berat kering, serapan hara N dan P tertinggi didapat pada perlakuan T8. Pemberian perlakuan pukan, BP, dan gamal memberikan hasil terbaik terhadap penyerapan unsur haraKata kunci : selada, anorganik, organik, nitrogen, fosfor

Abstract

The purpose of this research was to study dialel crossing of 4 soybean varieties in order to get drought resistant varieties. The research used Completely Randomized Design with six crossing combination : Dering x Grobogan, Grobogan x Dering, Dering x Detam, Detam x Dering, Dering x Devon, and Devon x Dering. Each combination was repeated five times. Parameters observed were percentage of fertilization, number of seeds in pods, long of pods, weight of 10 seeds. Parameters were analyzed descriptively and heterosis was calculated. The research results showed that crossing between dering and devon had the highest percentage of fertilization. Crossing between dering and grobogan improved number of seed in pod, long of pods and weight of 10 seeds. The highest heterosis of seed number in pod, long of pods and weight of 10 seeds were resulted from crossing dering x devon, Dering x Grobogan, Grobogan x Dering, respectively. Keywords : Crossing, genotype soybean, fist population
