Abstract

Potato is an important food crop in both developed and developing countries and it is the fourth most important food crop after wheat, maize, and rice. Potato production in Indonesia has decreased in recent years, mainly due to the use of low quality tuber seed. The objective of this research was to determine the effect of plant materials, types of nutrients, and planting density on mini tuber formation, as well as to determine the best aeroponics conditions for mini tuber formation of Granola cultivar of potato. This research has been carried out experimentally using a Split-split Plot Design. The main plot was planting materials which consisted of plantlet and knol. The subplot was the type of nutrition media which consisted of Farran nutrition, Otazu nutrition, and AB-commercial mix. The sub-sub-plot was planting density which consisted of 50, 75, and 100 plants/m2. The research results showed that knol planted in aeroponics system on AB-commercial mix at a planting density of 75 plants/m2 resulted in the best mini-tuber production. In this study, for the first time three important factors for potato mini-tuber production have thoroughly been investigated in Indonesia. This finding will be used by Kledung Horticultural Seed Garden, Temanggung, for mass production of high-quality mini-tuber seed, which in turn will provide sufficient tuber seed for the farmer in its surrounding areas. By increasing the production of high-quality tuber seed, it is expected that it will contribute to the improvement of potato productivity and increase Indonesian potato production.

Abstract

Shallot (Allium ascalonicum L) is an important horticultural sub-sector commodity and potential to be developed. Nevertheless, the production fluctuates due to the use of vegetative seeds in cultivation. Currently, there are still a few true seed shallot (TSS) varieties circulating for production. TSS diversity is needed by the colchicine mutation supported by a proper planting media composition. The experiment aimed to determine the effect and obtain the best colchicine concentration with media composition on the performance of Lokananta shallot. The experiment used a randomized group design with two factors. The first factor was colchicine concentrations i.e. 0%, 0.25%, 0.50%, and 0.75%. The second factor was the composition of media i.e. soil + goat manure), soil + husk charcoal, and soil + husk charcoal + manure. The observations were the percentage of growing seeds (%), growth, and yield characteristics. The results showed that the concentration of colchicine and planting media affected on plant height, leaf area, number of leaves, dry plant weight, dry bulb weight, escaped dry bulb weight, number of tillers, and number of bulbs. Colchicine concentration with media composition only interacted on fresh plant weight with 0.75% colchicine with planting media soil + manure (1:1). Bawang merah merupakan komoditas hortikultura penting dan berpotensi dikembangkan sebagai tanaman obat. Produksi bawang merah masih fluktuatif karena menggunakan benih vegetatif pada budidayanya. Saat ini, masih sedikit varietas true seed shallot (TSS) yang beredar di masyarakat. Diperlukan keragaman TSS melalui mutasi dengan kolkisin dan didukung komposisi media tanam yang tepat. Percobaan bertujuan untuk mengetahui pengaruh dan memperoleh konsentrasi kolkisin dengan komposisi media terbaik terhadap penampilan bawang merah Lokananta. Percobaan menggunakan rancangan acak kelompok dengan 2 faktor. Faktor pertama konsentrasi kolkisin yang terdiri dari konsentrasi 0%, 0,25%, 0,50%, dan 0,75%. Faktor kedua komposisi media tanam yang terdiri atas tanah + pupuk kandang kambing, tanah + arang sekam, dan tanah + arang sekam + pupuk kandang kambing. Variabel pengamatan yaitu persentase benih tumbuh (%), karakter agronomi dan hasil. Hasil penelitian menunjukkan bahwa konsentrasi kolkisin dan komposisi media tanam berpengaruh terhadap tinggi tanaman, luas daun, jumlah daun, bobot tanaman kering, bobot umbi kering, bobot umbi kering eskip, luas daun, jumlah anakan, dan jumlah umbi. Konsentrasi kolkisin dengan komposisi media hanya berinteraksi pada bobot tanaman segar. Pemberian kolkisin 0,75% dengan komposisi media tanam tanah + pupuk kandang kambing (1:1) mampu meningkatkan bobot tanaman segar.

Abstract

Pak choy is rich in calcium, magnesium, phosphorus, iron, and vitamin K, all essential for health. Pak choy requires a proper balance of nutrients for optimal growth. In a hydroponic system, any imbalance in nutrient levels can negatively impact plant growth and reduce the nutritional value stored in the tissues.  Selecting suitable varieties and providing appropriate calcium treatment can help increase calcium content and enhance productivity. This study aims to determine the effect of calcium concentration on growth, yield, and Ca content and the most responsive varieties to increased calcium concentration. The research design used was a Split Plot Design with two factors, namely calcium nitrate concentration (k) as the main plot consisting of k0 = without addition of Ca(NO3)2, k1 = addition of 300 mg/L Ca(NO3)2, k2 = addition of 600 mg/L Ca(NO3)2, k3 = addition of 900 mg/L Ca(NO3)2, and k4 = addition of 1200 mg/L Ca(NO3)2. Varieties (v) as subplots consist of v1 = Masbro, v2 = Nauli F1, and v3 = Flamingo. The results showed that the Nauli F1 variety had the best effect on the number of leaves, growth rate index, and fresh weight of shoots. Adding 900 mg/L of calcium nitrate had the best impact on plant growth, while adding 1200 mg/L of calcium nitrate caused plant poisoning. The Masbro variety was responsive to Ca biofortification.

Abstract

Tanaman aaren memiliki prospek yang baik untuk dikembangkan, karena semua bagian dari tanaman aren dapat dimanfaatkan, antara lain menjadi gula aren yang mengalami peningkatan permintaan pasar. Upaya untuk meningkatkan produksi aren harus dilakukan agar permintaan aren dapat terpenuhi, antara lain dengan pemupukan bibit aren menggunakan pupuk organik cair (POC) yang ramah lingkungan. Penelitian ini bertujuan mengetahui pertumbuhan bibit aren pada berbagi konsentrasi dan frekuensi penyemprotan POC. Penelitian ini dilakukan di Desa Sunyalangu, Kecamatan Karanglewas, Kabupaten Banyumas pada bulan Maret sampai Juni 2020. Rancangan yang digunakan dalam penelitian yaitu Rancangan Acak Kelompok (RAK) yang terdiri dari dua faktor, yaitu konsentrasi POC (1 ml/l, 2 ml/l dan 3 ml/l) dan frekuensi penyemprotan ( 1 minggu sekali, 2 minggu sekali dan 3 minggu sekali). Variabel pengamatan terdiri dari tinggi tanaman, jumlah daun, bobot tanaman segar, bobot tanaman kering, bobot tajuk segar, bobot tajuk kering, kehijauan daun, volume akar, panjang akar, bobot akar segar dan kering. Data penelitian diuji dengan uji F (ANOVA) pada taraf kesalahan 5% apabila hasil menunjukan adanya pengaruh nyata, maka dilanjutkan dengan Duncant’s Multiple Range Test pada taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa konsentrasi POC tidak berpengaruh terhadap pertumbuhan bibit tanaman aren. Frekuensi penyemprotan POC hanya berpengaruh terhadap kandungan klorofil daun (27,14 unit) dengan perlakuan terbaik adalah frekuensi 2 minggu sekali. Interaksi kedua perlakuan hanya berpengaruh terhadap tinggi bibit tanaman aren, yaitu dengan perlakuan terbaik pada konsentrasi 2 ml/l dengan frekuensi 2 minggu sekali menghasilkan tinggi tanaman sebesar 72 cm.

Abstract

One of the important factors influencing crop production is nutrition, which depends on soil fertility and fertilizer application. Nutrition will affect the weight loss of shallots. Shallots can loss weight loss of 25-40% during drying and 17% during storage. One of the nutrients that affect weight loss is potassium. Potassium is an element that plays an important role for plants in the process of photosynthesis, energy storage, protein synthesis, translocation of photosynthetic products. Potassium also plays a role in protecting the osmotic potential of plants in regulating the closing and opening of stomata so that plants can maintain water conditions which will have a good impact on photosynthesis and the flow of assimilate from leaves to plant parts. This study aimed to determine the effect of liquid potassium fertilizer plus application on the quality of shallots. The research was conducted in Adipala, Cilacap which has a height of 10 m above sea level and a temperature ranging from 23-30o C. The land area used is 50 m2. The study was conducted from June 2021 to September 2021. This study used a non-factorial randomized block design with four treatments, namely (1) 0 ml/plot, (2) 1 ml/plot, (3) 1.5 ml/plot, and (4) 2 ml/plot with ten replications. Data were analised using Anova and than follow DMRT at error 0,5%. The variables observed were: plant height, number of leaves, number of bulb, total fresh weight, total dry weight of askip, bulb diameter, bulb hardness and crop yield/plot. The results showed that the application of liquid potassium fertilizer plus had no significant effect on plant height, number of leaves, number of bulb, total fresh weight, total dry weight of askip, blub diameter, and crop yield/plot, but significantly affected the hardness of shallot bulbs.
