Pengaruh Pupuk Organik Dan Anorganik Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.)
ABSTRACT
This study aims to determine the single factor of petroganic organic fertiliser, the single factor of NPK phonska fertiliser and the interaction of petroganic organic fertiliser with NPK phonska and get the best dose. The research was conducted at the Faculty of Agriculture, Riau University for three months starting from January to March 2022. The first factor was the dose of petroganic (L) which consisted of L0: 0 tonnes.ha-1, L1: 1,250 kg.ha-1, L2: 2,500 kg.ha-1, L3: 3,750 kg.ha-1. The second factor is the dose of NPK phonska fertiliser (V) which consists of V0 = 0 kg.ha-1, V1 = 100 kg.ha-1 V2 = 200 kg.ha-1, V3 = 300 kg.ha-1. The experiment consisted of 16 treatment combinations, and each treatment combination was repeated three times, thus requiring 48 experimental units. The results showed that the interaction of petroganic organic fertiliser with NPK phonska had a significant effect on the parameters of tuber diameter, number of tubers per clump, wet weight of tubers per clump and dry weight of tubers per clump. The provision of NPK phonska fertiliser has a significant effect on the parameters of tuber diameter, number of tubers per clump, wet weight of tubers per clump and dry weight of tubers per clump. The application of petroganic organic fertiliser has no significant effect on all treatments. The application of petroganic organic fertiliser at a dose of 3.750 kg.ha-1 and NPK phonska fertiliser at a dose of 200 kg.ha-1 give the best results on the growth and production of shallot plants.
