Pengaruh Volume dan Frekuensi Pemberian Air Cucian Beras Terhadap Pertumbuhan Bibit Tanaman Karet (Hevea brasiliensis Muell.) Klon GT 1

Abstract

Rubber is one of main commodities of plantation crops that numerously developed in various districts in Indonesia. The role of the plant is strategic in human life in line with the increasing demand of world rubber. The optimum production increament of the rubber plant begins with the selection of a superior clone and the use of quality seeds. Fertilizing as a means of providing soil nutrients to plants should also be taken carefully. One of the fertilization is by the provision of organic fertilizers in the form of washed rice water. This research aims to find out the effect of washed rice water in a different volume and frequency applied as organic fertilizer on the growth of rubber seedling GT1 clone.The experiment wasconductedfrom September 2011 toJanuary2012 atthe Experimental Station of Faculty of Agriculture, Universitas Padjadjaran. The experiment was arranged inRandomized Block Designed, with 9 treatments and 3 replications, thus there are 27 units of the experiment. The treatments were providing 100 ml washed rice water with frequency of 3 days, 100 ml washed rice water with frequency of 5 days, 100 washed ml rice water with frequency of 7 days, 300 ml washed rice water with frequency of 3 days, 300 ml washed rice water with frequency of 5 days, 300 ml washed rice water with frequency of 7 days, 500 ml washed rice water with frequency of 3 days, 500 mL washed rice water with frequency of 5 days, and 500 ml washed rice water with frequency of 7 days. The results of the experiment showed that by providing 500 ml washed rice water with frequency of 3 days gave the best increament for stem height and diameter on rubber seedling GT1 clone.

Pengaruh Pemberian Pupuk Anorganik dan Pupuk Organik Cair (POC) Limbah Air Cucian Beras Terhadap Pertumbuhan dan Hasil Tanaman Sawi (Brassica juncea L.)

“…Air cucian beras merupakan salah satu limbah yang akan mudah ditemui dalam kehidupan sehari-hari. Konsumsi beras yang tinggi menyebabkan banyaknya air cucian beras yang terbuang dan jarang untuk dimanfaatkan (Ariyanti et al, 2018). Pada proses pencucian limbah air cucian beras bewarna putih susu.…”

PENGARUH PEMBERIAN PUPUK KOMPOS SOLID TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L) DI POLIBAG

“…Sebagai pemenuh kebutuhan unsur hara pada tanaman diperlukan penggunaan pupuk organik dan anorganik yang mampu meningkatkan unsur hara pada tanaman kakao. Penggunaan pupuk anorganik secara berlebihan dan digunakan dalam jangka waktu yang lama akan menyebabkan menurunnya kesuburan biologis tanah (Ariyanti et al, 2018).…”

Respon Pertumbuhan Dan Hasil Selada (Lactuca Sativa L.) Terhadap Interval Waktu Aplikasi Pemberian Air Cucian Beras

“…Tidak hanya bermanfaat untuk tanaman hortikultura, nyatanya air cucian beras juga berpengaruh pada tanaman perkebunan yaitu tanaman karet. Air cucian beras sebanyak 500 ml yang diaplikasikan setiap 3 hari sekali memberikan pengaruh terbaik pada pertumbuhan bibit karet klon GT 1 pada variabel pengamatan tinggi dan pertambahan lilit batang [7]. Hasil penelitian menunjukkan bahwa bibit kelapa sawit selama di prenursery mampu meningkatkan variabel tinggi tanaman, lebar daun, panjang daun, panjang akar, berat segar total, berat kering akar dan berat kering total dengan pemberian sebanyak 200 ml air cucian beras dan 300 ml air kelapa [8].…”
