Abstract

Lettuce (Lactuca sativa L.) classified in compositae family (Asteracea). The genetic source of lettuce derived from America and West Asia, whereas in Indonesia this plant growing so fast as commercial vegetable plant. Lettuce cultivation system that done by Indonesian farmers commonly is conventional. The efforts to increase productivity and quality of lettuce are conventionally hydroponic with wick system through testing of Type and Concentration of Nutrition. This research was held on February – March in Green house of Agriculture Faculty of UPN “Veteran” East Java. This study as factorial experiment 2 factor composed in Complete Random Design (CRD) and repeated 3 times. The first factor is the type of nutrition and the second factor is the concentration of nutrition, results showed there is no real interaction in all observation variables which include: number of leaves, length of the plant, large of leave, fresh weight and dry weight. Nutrition type give real effect on fresh weight, dry weight, and large of leave of the lettuce plant. AB Mix nutrition resulting in highest fresh weight and large of leaves and real different with Riyant nutrition. Concentration treatment unaffected in whole observation changes of growth and lettuce production.

Abstract

Increasing production of cayenne plant commodities can be done easily and cheaply, enough to do with the selection of varieties and appropriate cultivation techniques, one of which is the time of pruning. The purpose of this study was to determine the growth and yield of three varieties of cayenne pepper due to the time of shoot pruning. This research was conducted in the UPT greenhouse for Food Crops and Horticulture Agribusiness Development East Java, Sidoarjo in February-June 2019. This research was a factorial experiment prepared using a Completely Randomized Design (CRD) consisting of two factors and repeated three times. The first factor is the time of shoot topping with four levels of treatment, including without topping, topping 7 HST, 14 HST and 21 HST. The second factor is variety with three levels, namely, Mhanu F1 variety, CR ASA 7 and OR Kencana. Observation parameters included plant height, number of leaves, number of productive branches, number of flowers, number of fruits per harvest period, total number of fruits, fruit set, fresh fruit weight per harvest period and total fresh fruit weight. The combination treatment of P3V3 produced the highest total number of fruits (102,33 fruits) and the heaviest total fresh fruit weight (288.10 g), significantly different from all treatments. The treatment of shoot trimming time significantly affected all observation parameters. The use of three varieties significantly affected the parameters of plant height, number of flowers, number of fruit plants per harvest and weight of fresh fruit plants per harvest

Abstract

The ginger plant (Zingiber officinale) is one of the plant commodities included in the Zingiberaceae family known as ginger. The ginger plant was the most popular spice and was used by Europeans in antiquity. Apart from being an herbal plant, the ginger plant stores antioxidant substances that are useful for the health of the human body. In 2016, ginger crop production tended to decline while demand continued to increase. Therefore, the breeding of ginger plants can be carried out using growth regulators auxin which can spur the growth and development ginger. The purpose of this study was to determine the optimal formulation against the growth of ginger in the vegetative phase. The study was conducted from February to April in Agricultural Land, Faculty of Agriculture, University of National Development "Veteran" East Java. This study used an experiment compiled using a Complete Randomized Design (RAL) and repeated 3 times. Factor I Atonic ZPT Concentration of 0 ml/l (control), Atonic ZPT Concentration of 2 ml/l, Atonic ZPT Concentration of 4 ml/l, Atonic ZPT Concentration of 6 ml/l, Atonic ZPT Concentration of 8 ml/l, and Atonic ZPT Concentration of 10 ml/l. Factor II Emprit Ginger Variety, and Red Ginger Variety. The results showed that the difference in the dose of atonic growth regulator (ZPT) concentration against dry weight in the vegetative phase had a BNT value of 5% amounting to 7.95. This is because proper administration of auxin can increase nutrient absorption through the roots. In the results of the study, there was also a noticeable difference in the differences in ginger plant varieties that differed markedly from the root length with a BNT value of 5% amounting to 12.46. This is because the hormone can spur and spur biochemical activity. In the diameter of the stem, there is a noticeable difference in the difference in ginger plant varieties which is significantly different with a LSD value of 5% amounting to 0.36. This is because the material used to support the formation of rhizomes is available in large supply, the rhizomes formed are larger and affect the diameter of the rhizomes.

Abstract

Salah satu cara peningkatan produksi komoditas tanaman cabai rawit dapat dilakukan dengan waktu pemangkasan pucuk. Tujuan dari penelitian ini adalah untuk mengetahui pertumbuhan dan hasil tiga varietas cabai rawit akibat perlakuan waktu pemangkasan pucuk. Penelitian ini dilaksanakan di greenhouse UPT Pengembangan Agribisnis Tanaman Pangan dan Hortikultura Jawa Timur pada Pebruari-Juni 2019. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua faktor dan diulang tiga kali. Faktor pertama yaitu waktu pemangkasan pucuk dengan empat taraf perlakuan, antara lain tanpa pemangkasan pucuk, pemangkasan pucuk 7 hst, 14 hst dan 21 hst. Faktor kedua yaitu varietas dengan tiga taraf yaitu, varietas Mhanu F1, CR ASA 7 dan OR Kencana. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, jumlah cabang produktif, jumlah bunga, jumlah buah per periode panen, jumlah buah total, fruit set, bobot buah per periode panen dan bobot total buah segar. Perlakuan kombinasi P3V3 (pemangkasan pucuk pada umur 21 hst, varietas OR Kencana) menghasilkan jumlah buah total terbanyak (102 buah) dan bobot buah segar total terberat (288,10 g), berbeda nyata dengan semua perlakuan. Perlakuan waktu pemangkasan pucuk berpengaruh nyata pada semua parameter pengamatan. Penggunaan tiga varietas berpengaruh nyata pada parameter tinggi tanaman, jumlah bunga, jumlah buah tanaman per panen dan bobot buah segar tanaman per panen.

Abstract

Tanaman jahe (Zingiber officinale) merupakan salah satu komoditas tanaman yang termasuk dalam suku Zingiberaceae yang dikenal dengan ginger. Tanaman jahe merupakan rempah yang paling populer dan dimanfaatkan bangsa Eropa pada jaman dahulu. Selain sebagai tanaman herbal, tanaman jahe menyimpan zat antioksidan yang berguna bagi kesehatan tubuh manusia. Pada tahun 2016, produksi tanaman jahe cenderung mengalami penurunan sedangkan permintaan terus meningkat. Oleh karena itu, perkembangbiakan tanaman jahe dapat dilakukan dengan menggunakan zat pengatur tumbuh auksin yang dapat memacu pertumbuhan dan perkembangan tanaman jahe. Tujuan penelitian ini adalah untuk mengetahui formulasi yang optimal terhadap pertumbuhan tanaman jahe pada fase vegetatif. Penelitian dilakukan pada bulan februari hingga bulan April di Lahan Pertanian, Fakultas Pertanian, Universitas Pembangunan Nasional “Veteran” Jawa Timur. Penelitian ini menggunakan percobaan yang disusun menggunakan Rancangan Acak Lengkap (RAL) dan diulang sebanyak 3 kali. Faktor I Konsentrasi ZPT Atonik sebesar 0 ml/l (kontrol), Konsentrasi ZPT Atonik sebesar 2 ml/l, Konsentrasi ZPT Atonik sebesar 4 ml/l, Konsentrasi ZPT Atonik sebesar 6 ml/l, Konsentrasi ZPT Atonik sebesar 8 ml/l, dan Konsentrasi ZPT Atonik sebesar 10 ml/l. Faktor II Varietas Jahe Emprit, dan Varietas Jahe Merah. Hasil penelitian menunjukkan perbedaan dosis konsentrasi Zat Pengatur Tumbuh (ZPT) Atonik terhadap berat kering pada fase vegetatif memiliki nilai BNT 5% sejumlah 7,95. Hal ini disebabkan karena pemberian auksin yang tepat dapat meningkatkan penyerapan unsur hara melalui akar. Pada hasil penelitian juga didapatkan perbedaan yang nyata pada perbedaan varietas tanaman jahe yang berbeda nyata terhadap panjang akar dengan nilai BNT 5% sejumlah 12,46. Hal ini disebabkan karena hormon tersebut dapat memacu serta memacu uatu aktivitas biokimia. Pada diameter batang memiliki perbedaan yang nyata pada perbedaan varietas tanaman jahe yang berbeda nyata dengan nilai BNT 5% sejumlah 0,36. Hal ini disebabkan karena bahan yang digunakan untuk menyuplai pembentukan rimpang tersedia dalam jumlah banyak, maka rimpang yang terbentuk lebih besar dan memengaruhi diameter rimpang.
