ABSTRACT   This research aimed to determine the effects of compost applications on ex-mining lands by using chinese cabbage as indicator. The experiments were conducted at the Faculty of Agriculture greenhouse and the soil and compost analysis were done at the Soil Chemistry and Fertility Laboratory for a duration of two months. The research employed a Completely Randomized Design method with 5 treatments repeated 3 times to get 15 experimental units. The analysis on ex-mining soil revealed that it contained only trace amounts of soil nutrients N, P, and K. The laboratory analysis on the compost sample resulted in a C/N ratio of 11.87 which suggested that the compost was mature and ready to be used. The Analysis of Variance on research data showed that compost applications did not affect plant height between treatments at each weekly observation, and similarly did not affect leaf quantity and fresh weight at harvest time.  However, the research found that the compost applications tended to improve plant height, leaf quantity, and fresh weight of plants at harvest time.  The minimal effect of compost applications between treatments suggested that the plants did not utilized the nutrients supplied by the compost in their early stages of development.  Moreover, it was also suspected that the compost applications had not been sufficient in supplying the soil nutrients needed by the plants to ensure proper growth which ultimately affected the fresh weight of the plants at harvest time.

High salinity irrigation will cause nutrient uptake and shallot growth to deplete due to its sensitivity to salinity. This research aimed to investigate the effect of biochar and compost on shallot growth and nutrient uptake in sandy soil like Entisol when irrigated using salty water. This research carried out some pot experiments and put on the field using a completely randomized design. The first factor was based on the amendment with control of 20 tons ha<sup>-1</sup> of Biochar, 10 tons ha<sup>-1</sup> of compost, and a mixture of 10 tons ha<sup>-1</sup> biochar and 5 tons ha<sup>-1</sup> of compost; the second factor was composed of 3 shallot cultivars (Brebes, Pemalang, and Purbalingga). Each pot was filled with 15 kg of soil; the pot 30 cm in diameter, incubated with saline water and irrigated by 2 dS m<sup>-1</sup>. The results show that irrigation with ground saline water causes Entisol to increase exchangable Na, Ece and SAR, decrease exchangeable Ca and Mg. The application of all treatments decreased SAR. The application of compost significantly increased N and K uptake but made soil pH, EC, and SAR to decrease while fresh weight and dry weight of bulb in Brebes cultivars increased. The combination of biochar with 5 tons ha<sup>-1</sup> of compost produced the highest yield on plant height and number of tuber in Pemalang cultivars and had the largest tuber diameter in Purbalingga cultivars. There is an interaction between amendment and cultivar on plant height, fresh weight of tuber (P&lt;0.01), dry weight of tuber (P&lt;0.01).
