Respon Tembakau Madura Terhadap Dua Tipe Pupuk Organik

Responses of madura tobacco to two types of organic fetilizersThe research was conducted to find out the effect of the Enriched Organic Fertilizer (POD) of industrial by product and Farmyard Manure (FYM) on soil physical properties, nutrient uptake, plant performance, yield, and quality of madura tobacco. Field experiment was conducted from April to September 2002 in upland ield of Guluk-guluk village, Guluk-guluk sub district, Sumenep. The research used randomized completely block design (RCBD) with 9 combinations of organic fertilizer kinds and dosages and 4 replications. The results showed that the POD gave higher effect and nutrient contents than that of FYM. The POD could increase the field capacity soil moisture and K biomass concentration. The best treatment of the POD was 5 000 kg/ha, which gave yield I 156 kg, dried sliced leaves/ha, quality index 73.4 and crop index 77.2. The application of the POD 1 000 kg/ha produced 849 kg dried sliced leaves/ ha, quality index 76.8, and crop index 60.0, which was better than that of FYM 5 000 kg/ha. The application of POD 7 000 kg/ha caused worse response of tobacco compared to that of 5 000 kg/ha
