Abstract

The research aimed to increase the quality of manure to “Kotpi Plus” and to study the effect on growth and yield of sweet corn. The research used monofactor randomized block design with six treatments and 5 replications. The treatments were T0. Control; T1. 100% “Kotpi Plus” + 0% Urea and TSP (UT); T2. 75% “Kotpi Plus” + 25% UT, T3. 50% “Kotpi Plus” + 50% UT; T4. 25% “Kotpi Plus” + 75% UT; and T5. 0% “Kotpi Plus” + 100% UT. Parameters measured were plant height, leaf number, cob length, cob weight with cornhusk, and sum of seed row in a cob. Data were subjected to analysis of variance and followed by DMRT at α = 5%. The result on plant height and leaf number showed that T4 167.7 cm was significantly higher compared to control and 8.21 leaves significantly higher compared to control and T1, respectively. “Kotpi Plus” combined with inorganic fertilizer produced cob length significantly higher compared to control. Cob weight with cornhusk on T4 was significantly higher compared to T0 and T1. The given of “Kotpi Plus” fertilizer was not affecting on sum of seed row in a cob. Keywords: Gliricidia sepium, growth, phosphate rock, sweet corn, yield.

Abstract

ABSTRAK  Penelitian bertujuan untuk mengkaji jenis naungan yang sesuai dan sasaran pemberian paklobutrazol yang tepat untuk pertumbuhan serta pembungaan anggrek Dendrobium sp. Penelitian menggunakan Pooled Design dengan perlakuan naungan : N1 (naungan 30%), N2 (naungan 50%), N3 (naungan 70%), serta cara pengaplikasian paklobutrazol : P0 (kontrol), P1 (disemprotkan pada akar), P2 (disemprotkan pada daun), P3 (disemprotkan pada akar dan daun), diulang sebanyak 3 kali. Parameter yang diamati meliputi tinggi tanaman, diameter batang, klorofil total, dan waktu inisiasi bunga anggrek. Data dianalisis ragam dan uji lanjut dengan BNT pada taraf α = 5%. Hasil penelitian menunjukkan bahwa naungan 50% berpengaruh pada tinggi tanaman (26,97 cm) dan diameter batang (1,57 cm), naungan 70% juga berpengaruh terhadap tinggi tanaman anggrek (29,30 cm) dan klorofil total (0,55 mg/g). Paklobutrazol tidak memiliki pengaruh terhadap tinggi tanaman dan diameter batang. Paklobutrazol hanya berpengaruh terhadap kandungan klorofil total. Interaksi antara perlakuan naungan 70% dan pemberian paklobutrazol pada daun, menunjukkan kadar klorofil tertingi sebesar 0,71 mg/g. Faktor pemberian naungan dan paklobutrazol tidak mempengaruhi pembungaan anggrek, tapi inisiasi bunga mulai terlihat di beberapa tanaman. Waktu inisiasi bunga terjadi saat hari ke 71 – 126 setelah perlakuan. Semua inisiasi bunga tidak dapat berkembang menjadi rangkaian bunga. Kata kunci: anggrek, paklobutrazol, naungan, pertumbuhan, pembungaan. ABSTRACT  The research aimed to examine the appropriate shade types and target of paclobutrazol giving for growth and flowering of Dendrobium sp. The research used Pooled Design with shade treatment: N1 (30% shade), N2 (50% shade), N3 (70% shade), treatment of paclobutrazol application: P0 (control), P1 (sprayed on roots), P2 (sprayed on leaf), P3 (sprayed on roots and leaf), replicated three times. Parameters measured were plant height, stem diameter, total chlorophyll, and the initiation time of orchid flowers. Data analyzed with anova and followed by LSD at α = 5%. The results showed that 50% shade affect plant height (26.97 cm) and stem diameter (1.57 cm), the 70% shade also affect plant height (29.30 cm) and total chlorophyll (0.55 mg/g). Paclobutrazol has no effect on plant height and stem diameter. Paclobutrazol only affect the total chlorophyll content. The interaction between the shade treatment of 70% and the application of paclobutrazol in leaves, showed the highest total chlorophyll content of 0.71 mg/g. Shading and paclobutrazol factors do not affect the flowering of orchids, but the flower initiation begins to be seen in some plants. The initiation time of flower occurs at days 71 to 126 after treatment. All flowers initiation didn’t develop into a flower arrangement. Keyword: orchid, shade, paclobutrazol, growth, flowering

Abstract

ABSTRACT Orchids are ornamental plants that lived in the wild as epiphytes, utilized the visual side of the flower. Problems arise is a relatively long time to be able to enjoy the flowers. Split technique is an alternative that produces special orchids especially of Dendrobium type with the same properties as its mother in a relatively short time. The research was conducted in July-September 2017 in screenhouse, Faculty of Animal and Agricultural Sciences, Diponegoro University. This study aimed to know the interaction between type of nitrogen fertilizer and place of planting to vegetative growth of split Dendrobium sp. This study used Split Plot Design of Complete Randomized Design scheme with ten replications. The main plot was place of planting : T1 = attached to the coconut fiber then hung and T2 = grown in pot (coconut fiber) and subplot was the type of fertilizer: P1 = POC goat + Azolla microphylla, and P2 = Synthetic fertilizer. The variables observed were plant height, number of leaves, stem diameter, number of roots, and number of buds per plant. Data were analyzed by analysis of variance followed by LSD test at 5% level. The results showed that hook planting places significantly increased plant height and stem diameter. Synthetic fertilizer significantly increased plant height and number of leaves.There was interaction between nitrogen fertilizer and place of planting to stem diameter on vegetative growth results of split Dendrobium (Dendrobium sp.). Keywords: Dendrobium sp., nitrogen fertilizer, place of planting ABSTRAK  Anggrek merupakan tanaman hias yang hidup di alam bebas secara epifit, dimanfaatkan sisi visualnya terutama dari bentuk dan warna bunga. Masalah yang timbul adalah waktunya yang relatif lama untuk berbunga. Teknik split merupakan alternatif yang menghasilkan anggrek khususnya jenis Dendrobium dengan sifat sama seperti induknya dalam waktu yang relatif singkat. Penelitian dilaksanakan pada Juli-September 2017 di screen house, Departemen Pertanian, Fakultas Peternakan dan Pertanian, Universitas Diponegoro. Tujuan penelitian adalah untuk mengetahui pengaruh interaksi jenis pupuk dan tempat tanam terhadap pertumbuhan vegetatif hasil split Dendrobium sp. Penelitian ini menggunakan Rancangan Petak Terbagi (Split Plot) skema RAL dengan 10 kali ulangan. Petak utama (main plot) adalah tempat tanam: T1 = dilekatkan pada serabut kelapa kemudian digantung dan T2 = ditanam dalam pot (serabut kelapa) dan anak petak (sub plot) adalah jenis pupuk: P1 = POC kotoran kambing+Azolla microphylla, dan P2 = pupuk sintetis. Variabel yang diamati antara lain adalah tinggi tanaman, jumlah daun, diameter batang, jumlah akar, dan jumlah tunas per tanaman. Data yang diperoleh dianalisis dengan ANOVA dan dilanjutkan dengan uji BNT (Beda Nyata Terkecil) pada taraf 5%. Hasil penelitian menunjukkan bahwa tempat tanam gantungan meningkatkan tinggi tanaman dan diameter batang secara signifikan. Pupuk sintetis meningkatkan tinggi tanaman dan jumlah daun secara signifikan. Terjadi interaksi antara pemberian pupuk nitrogen dan tempat tanam terhadap diameter batang pada pertumbuhan vegetatif hasil split Dendrobium (Dendrobium sp.).
