The intensive application of synthetic/inorganic fertilizer on shallot cultivation tends to contaminate the environment and reduce soil quality. Meanwhile, the decrease of farmland area has been a limiting factor in increasing shallot production. Shallot farmers in Bantul District, D. I. Yogyakarta, commonly combine organic and inorganic fertilizers. Therefore, an alternative technology to sustain the production of shallot is through the application of fertilizer at the right rates and the practice of multiple cropping system. The objective of this research was to determine the growth and yield of shallot as affected by the reduced rates of inorganic fertilizer and different multiple cropping systems. This research was conducted from August to November 2016 in Srigading Village, Sanden Sub-District, Bantul District, D. I. Yogyakarta. The research was arranged in a split plot design with three replications. The main plot was cropping system consisting of monoculture system (shallot) and multiple cropping system (shallot – chili). The subplot was fertilizer rates consisting of 100 % as control, 50 %, and 25 %. The result of this research showed that multiple cropping system did not decrease the growth and yield of shallot. Likewise, reducing inorganic fertilizer rates to 50% of control did not decrease shallot yield. However, the inorganic fertilizer rate of 25% significantly decreased shallot yield to 12.15 %.

Moringa plants grow in Sumenep with semi-intensive planting at the moor and several planting sites. Sumenep is one of the districts in Madura Island, which is categorized as a dry area based on the Oldeman climate classification. Based on the color of the leaf stalk, moringa plants growing in Sumenep area are categorized as green and purple moringa. The study aimed to examine the differences in physiological characteristics of two accession of moringa plants at different planting sites in Madura. The study was arranged in Oversite Sub-sampling Design with planting site as first factor consisting of Bluto with E5 climate type and Guluk-guluk with D3 climate type. Meanwhile, the second factor was the type of moringa consisting of moringa with green and purple leaf stalks. The results showed that the different planting sites represented the differences in environmental elements, which influenced the physiological characteristics of moringa plants. Based on the observation in September 2016, moringa plants with green stalks planted in Guluk-guluk had high ANR content. The stomatal opening on moringa leaves with green stalks was larger than that on moringa plants with purple stalks, whereas ANR content in green-stalked moringa was lower than in the purple-stalked ones. Meanwhile, in February 2017, the purple-stalked moringa plants planted at Bluto had the highest transpiration rate and proline content compared to the others.
