RanggaFariyanaPutra, (2016) Pengaruh Pemberian Dosis Pupuk Dan Media Tanam Terhadap Pertumbuhan Tanaman Pak Choy ( Brassica Rapa L. Var Chinenesis ) Di Polibag. Sarjana thesis, Universitas Brawijaya.

Indonesian Abstract

Pak choy ( Brassica rapa L. var chinensis ) merupakan sayuran yang bermanfaat bagi tubuh manusia karena kandungan gizinya. Data produksi pak choy di Indonesia meningkat setiap tahunnya. Periode tahun 2009 - 2011, produksi pak choy meningkat dari 562.838 ton menjadi 591.225 ton (Badan Pusat Statistik, 2011). Daerah pusat penyebaran pak choy antara lain, Cipanas, Lembang, Pengalengan, Malang, dan Tosari. Untuk menunjang kesuburan media tanam pemberian pupuk anorganik juga diperlukan. Faktor lain yang dapat mempengaruhi pertumbuhan pak choy yaitu media tanam,karena media tanam adalah faktor terpenting sebelum kita melakukan penanaman. Berdasarkan uraian diatas penulis tertarik untuk melakukan penelitian respon penelitian Pengaruh beberapa pemberian dosis pupuk dan media tanam terhadap pertumbuhan tanaman pak choy ( Brassica rapa L. var chinensis) di polibag. Tujuan dari penelitian ialah untuk mengetahui pengaruh pemberian dosis pupuk dan juga pengaplikasian media tanam terhadap pertumbuhan yang terjadi pada tanaman pak choy ( Brassica rapa L. Var chinensis). Hipotesis penelitian ini ialah pengaruh pemberian dosis pupuk yang diberikan dan media tanam terhadap pertumbuhan tanaman pak choy ( Brassica rapa L. var chinensis) Penelitian ini dilaksanakan pada bulan juni sampai agustus 2016 di lahan Fakultas Pertanian Universitas Brawijaya, bertempat di perumahan Griyasanta, dengan perlakuan media tanam tanah, kompos, sekam dan juga menggunakan dosis pupuk untuk pertumbuhan tanaman pak choy. Penelitian dilakukan dengan menggunakan Rancangan Acak kelompok faktorial. Rancangan perlakuan terdiri dari dua faktor, yaitu faktor pemupukan dan media tanam. Dari kedua faktor tersebut didapatkan 12 kombinasi perlakuan. Pengamatan non destruktif meliputi Tinggi tanaman, Jumlah daun pertanaman. Pengamatan dilakukan pada umur tanaman 7 hst, 14 hst, 21 hst, 28 hst. Pengamatan destruktif meliputi Luas daun, Bobot basah tanaman, Bobot kering tanaman, dilakukan pada saat tanaman siap dipanen. Analisis data hasil pengamatan menggunakan uji F dengan metode Sidik Ragam (ANOVA) Apabila tidak terjadi interaksi dilakukan uji BNT 5% dilakukan pada hasil rata-rata perlakuan tunggal yang menpunyai pengaruh terhadap variabel pengamatan. Tidak terjadi interaksi antara perlakuan pemberian beberapa dosis pupuk dan media tanam pada parameter pengamatan tinggi tanaman, bobot segar, bobot kering dan luas daun, tetapi pada jumlah daun terdapat interaksi antara pemberian beberapa dosis pupuk dan media tanam yang berbeda nyata. Hasil pengamatan mingguan didapatkan perlaukuan pemberian beberapa dosis pupuk tidak ada interaksi dengan media tanam pada parameter jumlah daun yang tidak berbeda nyata pada 7 – 28 hari setelah tanam. Pada pengamatan bobot segar, bobot kering, dan luas daun tanaman pak choy, diperoleh hasil yang tertinggi yaitu kobinasi perlakuan dengan perbandingan dosis pupuk NPK 100 kg/ha : Urea 125 kg/ha : ZA 100 kg/ha ( P3 ) dan media tanam tanah, kompos, sekam dengan perbandingan 1 : 1 : 1 ( M3 ).

English Abstract

Pakcoy (Brassica rapa L. var chinensis) is a vegetable that is beneficial to the human body because of its nutrient content. Additionally, mustard commonly found on farms in Indonesia. The production data pak choy in Indonesia is increasing every year. The period of 2009 - 2011, pak choy production increased from 562 838 tonnes to 591 225 tonnes (the Central Bureau of Statistics, 2011). The central area of deployment pakcoy among others, Cipanas, Lembang, Canning, Malang, and Tosari. Especially areas that have a height above 1,000 masl. Society generally prefer fresh vegetables. This requires distribution and proper handling, so that the product pak choy is not damaged or wilted. To support the planting medium fertility inorganic fertilizer application is also required. Inorganic fertilizer containing nitrogen and are common elements include urea and ZA. With the provision of inorganic fertilizers or artificial fertilizers, especially fertilizers ZA, is expected to add to the content of N in the soil and can overcome the shortcomings of N in the soil, where ZA is very sour and is expected to lower the pH of the soil, thus increasing the levels of soil N, N uptake and pak choy crop. Urea is a fertilizer while the amine-containing organic compounds that have hygroscopic properties and are not easily terdenitrifikasi (Tisdale et.al, 1990). Another factor that can affect the growth of pak choy, namely the growing medium, because of the growing media is the most important factor before we do the planting. In the composition of planting pak choy composition planting medium used consisted of soil, compost and straw. Expected combination of the composition of the growing medium to optimize the growth of seedlings. Based on the description above, the writer interested in conducting research on the response research on influence of some degree of shade and growing media on plant growth pak choy (Brassica rapa L. var chinensis) in polybags. The purpose of the research was to determine the effect of the application of fertilizers and growing media on growth that occurs in plants pak choy (Brassica rapa L. var chinensis). The hypothesis of this study was the effect of a given dose of fertilizer and growing media on plant growth pak choy (Brassica rapa L. var chinensis). This research was conducted in June to August 2016 in UB Faculty of Agriculture land, located in a residential Griyasanta, with the medias treatment of planting soil, compost, husk and also use fertilizers for plant growth mustard or pakchoi. The tools used, polybags, buckets, shovels, lux meter, mica, bamboo, markers, writing equipment. While the materials used are of superior vaeietas mustard seed, soil, compost, ash, urea, ZA fertilizer, pesticides, water. The study was conducted using a factorial randomized design. The design of treatment consists of two factors, with three replications. The first factor is fertilization (P) consists of three levels, namely P0 = Without fertilization, P1 = NPK 50 kg / ha + Urea 75 kg / ha + ZA 50 kg / ha, P2 = NPK 75 kg / ha + Urea 100 kg / ZA ha + 75 kg / ha, P3 = 100 kg NPK / ha + 125 kg urea / ha + ZA 100 kg / ha. The second factor is the growing media (M) consists of three levels, namely M1 = Media planting soil: compost: chaff in the ratio 6: 3: 1, M2 = Media planting soil: compost: chaff in the ratio 3: 2: 1, M3 = media planting soil: compost: chaff in the ratio 1: 1: 1. Of these two factors combined treatment obtained 12. Observations using two non-destructive and destructive ways. Observations non destructive include plant height, number of leaves planting, stump diameter, light intensity (%). Observations were made on the age of the plant 7 hst, 14 hst, 21 hst, 28 hst. Observations destructively include leaf area, wet weights per plant, dry weight per plant, carried out when the plants are ready for harvest. Analysis of the observed data using the F test method Fingerprint Car (ANOVA) If there is no interaction do LSD 5% performed at an average yield of single treatment that menpunyai influence on observation variables. No interaction between treatment administration of multiple doses of fertilizers and growing media on the observation parameters plant height, fresh weight, dry weight and leaf area, but the number of leaves there is interaction between administration of multiple doses of fertilizers and growing media are significantly different. Weekly surveys obtained perlaukuan giving several doses of fertilizer there is no interaction with the planting medium on parameters number of leaves that are not significantly different at 7-28 days after planting. In observation of fresh weight, dry weight and leaf area of plants pak choy, obtained the highest results that kobinasi treatment by comparison dosage of NPK fertilizer 100 kg / ha: Urea 125 kg / ha: ZA 100 kg / ha (P3) and the planting medium ground , compost, husk with a ratio of 1: 1: 1 (M3).
