“Pengaruh Dosis dan Jenis Jus Buah terhadap Pertumbuhan Dan Produksi Tanaman Kentang (Solanum tuber rosum)

Abstract

Pemberian jus buah terhadap tanaman kentang yang memiliki berbagai jenis kandungan sangat bermanfaat untuk mengurangi pencemaran limbah buah buahan dan juga dapat menghemat penggunaan pupuk kimia yang harganya relatif mahal. Penelitian ini bert ujuan untuk mengetahui pengaruh pemberian jus buah jeruk dan tomat terhadap pertumbuhan dan hasil produksi tanaman kentang ( Solanum tuber osum L. ) . Penelitian ini menggunakan metode Rancangan Acak Kelompok ( RAK) dengan 2 perlakuan dan masing masing perlakuan di ulang sebanyak tiga kali. Perlakuan pertama yaitu pemberian jus buah jeruk yang terdiri dari 5 taraf konsentrasi yaitu: J0=0%(kontrol), J1=25%, J2=50%, J3=75%, J4=100% dan perlakuan kedua yaitu pemberian jus buah tomat yang terdiri dar i5t ar afkonsent r asiy ai t u:J0=0%( kont r ol ), J1=25%, J2=50%, J3=75 %, J4=100%. Terdapat 25 kombinasi perlakuan yang diulang sebanyak 3 kali sehingga menghasilkan 75 sampel tanaman penelitian. Parameter yang di ukur adalah jumlah daun, tinggi batang tanaman, jumlah umbi ken tang, berat umbi kentang. Data hasil penelitian di analisis dengan menggunakananalisis ofvarians ( ANOVA) dan di lanjutkan dengan uji beda rataan Duncan’ s Multiple RangeTest ( DMRT). Hasil penelitian menunjukkan bahwa pemberian jus buah jeruk dan tomat terhadap tanaman kentang sangat berpengaruh bedanyata ( sangat signifikan) terhadap setiap ulangan pada pengamatan juml ah daun, tinggi batang dan berat umbi kentang. Sedangkan pengamatan terhadap jumlah umbi kentang tidak berpengaruh beda nyata terhadap setiap ulangan (blok). Giving fruit juice to potato plants that have various types of content is very useful for reducing fruit waste pollution and can also save on the use of chemical fertilizers which are relatively expensive. The aim of this study was to determine the effect of giving orange and tomato juice on the growth and yield of potato (Solanum tuber osum L.) crop. This study used a Randomized Block Design (RAK) method with 2 treatments and each treatment was repeated three times. The first treatment was giving orange juice which consisted of 5 concentration levels, namely: J0=0% (control), J1=25%, J2=50%, J3=75%, J4=100% and the second treatment was giving tomato juice. which consists of i5t ar afconsent r asiy t u:J0=0% (control), J1=25%, J2=50%, J3=75 %, J4=100%. There were 25 treatment combinations which were repeated 3 times to produce 75 samples of research plants. Parameters measured were number of leaves, plant stem height, number of potato tubers, and weight of potato tubers. The research data were analyzed using the analysis of variance (ANOVA) and continued with the Duncan's Multiple Range Test (DMRT) mean difference test. The results showed that the application of orange and tomato juice to potato plants had a very significant effect on each replication in the observation of the number of leaves, stem height and weight of potato tubers. Meanwhile, the observation of the number of potato tubers did not significantly affect each replication (block).
