The flowering of shallot is influenced by low temperature and difference temperature between day and night. In Indonesia, to flowering shallot in low temperature are possible by planting in highlands. Because of climate change, the temperature difference in the highlands is very pronounced. This study aimed to determine the percentage of flowering and True Shallot Seed (TSS) production of three shallot varieties grown in the highlands. The research was conducted at Pancot Village, Tawangmangu, Karanganyar, Indonesia. The elevation of research site was 1, 300 m asl. The research design used was Split Plot with three replications. The main plot was variety: Bali Karet, Bali Lancur, and Bima Brebes. The subplot was fertilizers composition (Manure, ZA, SP36, KCl) and gibberellins: farmer’s dose (100% Inorganic and Organic) (P1G0), 100% Inorganic and Organic + Gibberellin 50ppm (P2G1), 50% Inorganic and 150% Organic (P3G0), 50% Inorganic and 150% Organic + Gibberellin 50ppm (P4G1), 200% Organic (P5G0), 200% Organic + Gibberellin 50ppm (P6G1). The results showed that fertilizer composition + gibberellins and varieties did not have significant effect on percentage of flowering, number of flowers and percentage of TSS formation. Fertilizer composition + gibberellins just influenced the number of TSS per stalks. Bima Brebes variety with P6G1 was able to flowering at 65 DAP with the flowering percentage reaching 88.87%.

Climate change hurts garlic cultivation. Appropriate technology needs to be created to get good quality tubers, one of them using bulbils. Bulbils are tubers formed from other parts of a plant. In garlic, bulbil grows at the stem, with very small embryo size hence it is necessary to control the environmental conditions in the nurseries. The study aimed to examine the garlic cultivation model using tubers with mulch treatment and a combination of fertilization. Sealing and mulching were conducted to avoid direct solar heat and to control the soil microclimate, respectively. The study used a split-plot design consisting of main plots with mulching and without mulching. The sub-plots were by applying the combination of organic and inorganic fertilizers at several levels, namely: Farmer Recommendation/P1 (50% Organic + 100% Inorganic), P2 (75% Organic + 25% Inorganic), P3 (50% Organic + 50% Inorganic), P4 (25% Organic + 75% Inorganic) and P5 (100% Organic). The results showed there are interactions between mulching and a combination of fertilizers on plant height and root length. Mulch application can stabilize soil temperature and provide better results on growth and yield, but the combination treatment of fertilization has no significant effects on growth variables and yields.

The use of shallot bulbs as the main planting material has many weaknesses, so one of the solutions is to use botanical seeds (True Shallot Seed). Physiologically, good seeds have embryos, endosperm, radicles, and testa. Seed viability demonstrated by the viability of seeds, metabolically active, and has enzymes that can catalyze metabolic reactions for germination. The purpose of this study was to determine the potential of the seed to determine its quality. One method for testing seed potential is the viability test through the tetrazolium test and the vigor test through Germination Rate. This research used local varieties of Trisula yields in 2015 (TR 1), Trisula yields of 2018 (TR 2) and as a control used Tuk-Tuk varieties. The results of the viability test using tetrazolium showed that the average viable seeds in the TR1 variety were 90.5%, TR2 94%, Tuk-tuk 95.5% which meant that the potential of the seed was still good because it was over 80%. The results of the vigor test through the measurement of germination rate gave significantly different results on each variable with an average yield of TR1 8.45% per etmal, TR2 11.41% per et mal, and Tuk-tuk 14.27% per et mal.

Bunga telang (Clitoria ternatea L) merupakan salah satu tanaman leguminosae yang memiliki manfaat farmakologis, namun sebagian besar pemanenannya berasal dari alam dan belum dibudidayakan secara luas.  Oleh karena itu perlu diadakan suatu  penelitian  spesifik terkait morfologi dan kandungan flavonoid bunga telang untuk dijadikan tanaman budidaya. Tujuan riset ini untuk mengkaji karakter morfologi dan kandungan metabolit sekunder (flavonoid) bunga telang di berbgai ketinggian.  Survei dilaksanakan di lokasi berbeda yaitu dataran rendah (Karangasem, Jeyengan dan Purwosari) dan dataran tinggi Ngargoyoso, mulai bulan Februari sampai April 2021.  Lokasi survei dipilih dengan metode acak memihak (purpose random sampling) melalui pendekatan pra-survei dimana tumbuhan tersebut bisa ditemukan, yaitu di dataran rendah Karangasem, Jeyengan, Purwosari dan dataran tinggi Ngargoyoso.  Pengujian kadar flavonoid dilakukan di Balai Besar Penelitian dan Pengembangan Tanaman Obat dan Obat Tradisional Tawangmangu.  Hasil penelitian menunjukkan adanya perbedaan morfologi bunga telang di dataran rendah dan dataran tinggi.  Karakteristik morfologi yang berbeda terletak pada panjang dan lebar daun, bentuk daun, panjang polong dan jumlah biji per polong.  Kandungan flavonoid tertinggi adalah di dataran rendah Karangasem sebesar 0,493% diikuti oleh dataran tinggi Ngargoyoso sebesar 0,458%, Purwosari 0,351% dan Jeyengan 0,297%.

<p>Penelitian ini bertujuan untuk mengidentifikasi pembudidayaan tanaman garut yang dilakukan oleh petani khususnya petani di desa Gilirejo wilayah tepian waduk Kedung Ombo dan mengetahui besarnya keuntungan yang didapat dari budidaya tanaman garut yang diusahakan oleh petani.</p><p>Penelitian ini merupakan penelitian kualitatif dalam bentuk survei tentang pembudidayaan tanaman garut oleh petani di desa Gilirejo tepian waduk Kedung Ombo dan demplot pemupukan pada penanaman garut sebagai pembanding terhadap hasil tanaman garut yang dihasilkan oleh petani. Waktu penelitian dilaksanakan mulai bulan Mei 2002 hiingga Oktober 2002.</p><p>Hasil penelitian menunjukkan: (1) Wilayah desa Gilirejo mempunyai kondisi dan luas lahan yang memungkinkan untuk pengembangan tanaman garut. (2) Cara-cara pembudidayaan tanaman garut yang dikerjakan petani umumnya masih sangat konvensional. Meskipun demikian tanaman garut yang mereka usahakan mampu menyumbang pendapatan bagi keluarga yang cukup bermakna. Dimana rata-rata pendapatan yang diperoleh keluarga dari tanaman garut sebesar Rp. 40.700,- dengan keuntungan bersih Rp. 23.400,-. (3) Pemupukan urea, SP36 dan KCl dengan dosis 100 kg/ha, 200 kg/ha dan 50 kg/ha mampu meningkatkan hasil umbi garut 1 kg/m² yang setara dengan 10 ton/ha. (4) Tambahan biaya tiap ha lahan akibat pemupukan sebesar Rp. 550.000,- ternyata mampu meningkatkan pendapatan sebesar Rp. 3.465.000,- dan keuntungan sebesar Rp. 2.915.000,-.</p>
