Agroforestry-based coffee is one of the conservation efforts to restore the damages at the Citarum watershed. Planting annual crops between coffee rows could potentially contribute income for the growers during the immature non-productive coffee growth. The aims of the research is to study the effect of various types of agroforestry models in the upstream Citarum watershed on the growth of coffee, and growth and yields of the intercrops. The research was conducted in September 2018 to June 2019 at the upstream Citarum watershed of Tarumajaya Subdistrict Kertasari, Bandung Regency, West Java, Indonesia. The research was arranged with a randomized block design with two factors. The first factor was the cropping system, i.e. coffee monoculture, coffee and corn, coffee and sweet corn, coffee and red beans, and coffee and habanero chili. The second factor was organic matter application, i.e. with and without application of in situ organic matter. The results of the research showed that coffee intercropped with habanero with application of in situ organic matter had the best vegetative growth, indicated by taller plants, more leaves, increased leaf P and Mg levels, and the maximum income from the intercrop. Coffee intercropped with corn with application of in situ organic matter had a maximum corn production but had the lowest income. Therefore, the model of coffee intercropped with habanero chili with application of in situ organic matter was the best model from several intercropping systems tested.

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Tailings are waste generated from the processing of gold ore. The tailings in Kertajaya Village, Sukabumi are generally dumped into a pond or garden which is then used by the community to grow crops. The characteristics of the tailings, which contain low organic matter, microorganism activity, CEC and essential nutrients, make it necessary to improve their condition. This study aimed to determine the effect of adding top soil and compost to the tailings on the growth of sweet potatoes in the vegetative phase. This experiment used a factorial randomized block design with two factors, namely a top soil-tailing ratio of 3 levels (70: 30% w/w; 50: 50% w/w; and 30: 70% w/w) and a compost dose of 4. level (without compost (control); 10 t ha-1; 20 t ha-1; and 30 t ha-1) with 3 replications. The results showed that the combination of the addition of top soil ratios and the dose of compost to the tailings had no effect on the addition of tendrils length, tendril diameter and number of sweet potato branches during the vegetative phase. The addition of 70% top soil independently on the tailings had an effect on the highest increase in tendril length, tendril diameter and number of branches of sweet potato. Meanwhile, the application of compost dosage of 30 t ha-1 had the highest effect on the number of branches of sweet potato.
