Combine organic and inorganic fertilizer increases yield of cucumber (Cucumissativus L.)

Abstract The aim of this study is to determine the effect of combine organic fertilizer (manure) and inorganic fertilizer (NPK and Micro fertilizer) on the growth and yield of cucumber (Cucumissativus L.). This study was conducted in the Experimental station, Agriculture Faculty, Universitas Syiah Kuala, Aceh from February to April2018. This experiment was arranged in a factorial randomized completely block design with two factors and three replications. The first factor was the provision of organic fertilizer (manure) with 3 levels: 10 t ha−1(K1), 20 t ha−1 (K2), and 30 t ha−1 (K3). The second factor was the provision of inorganic NPK fertilizer with 3 treatments: Without NPK fertilizer (control - N0), NPK Fertilizer(N 50 kg ha−1 P2O5 50 kg ha−1 and K2O 50 kg ha−1 (280 kg ha−1Phonska 16-16-16 - N1), and NPK + Micro Fertilizer (N 50 kg ha−1 P2O5 50 kg ha−1 and K2O 50 kg ha−1 (280 kg ha−1Phonska 16-16-16 + 2% Micro fertilizer – N2)). Results show that organic fertilizers (20 and 30 ton ha−1) increase fruit weight of each sample and fruit weight of each plant. The application of NPK + Micro Fertilizer produces in the best fruit weight of each sample and fruit weight of each plant. The combination of organic fertilizer (20 ton ha−1) and inorganic NPK + Micro Fertilizer results in the best fruit weight each plant of cucumber.
