Abstract
Cabai rawit merupakan salah satu komoditi sayuran yang mempunyai nilai ekonomi tinggi karena hamper selalu dipergunakan dalam segala macam masakan. Masalah yang sering dihadapi dalam budidaya cabai adalah produksi cabai yang rendah karena teknik budidaya yang belum diterapkan secara benar. Strategi untuk meningkatkan pertumbuhan dan hasil produksi tanaman cabai dengan menggunakan PGPR. Penelitian bertujuan untuk mengetahui pengaruh waktu terbaik dalam perendaman benih cabai dengan menggunakan PGPR, untuk mengetahui frekuensi pemberian PGPR yang terbaik, untuk mengetahui interaksi waktu perendaman benih dan frekuensi pemberian PGPR terhadap pertumbuhan dan hasil tanaman cabai rawit. Penelitian dilaksanakan di Desa barang, Kecamatan Jumo, Kabupaten Temanggung pada bulan juni sampai desember 2014. Metode yang digunakan dalam Penelitian ini adalah metode percobaan lapangan dengan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri atas dua faktor dan ditambah satu kontrol (Direndam air selama 1 jam). Faktor yang pertama (L) lama perendaman benih yang terdiri dari 3 aras yaitu L1 = 2 jam, L2 = 4 jam dan L3 = 6 jam. Faktor kedua yaitu (F) frekuensi pemberian PGPR yang terdiri atas 3 aras F1 = Satu minggu sekali, F2 = Dua minggu sekali dan F3 = Tiga minggu sekali, terdapat 9 kombinasi perlakuan diulang 3 kali. Terdapat interaksi terhadap parameter tinggi tanaman umur 42 hst,bobottotal buah per tanaman sampel dan bobot total buah per petak panen. Kombinasi perlakuan lama perendaman benih dengan frekuensi pemberian PGPR memberikan hasil terbaik pada tinggi tanaman umur 42 hst, jumlah total buahpertanamansampel, bobot total buah per tanaman sampel dan bobot total buah per petak panen. Lama perendamanbenih6 jam paling baik dalam mempengaruhi daya berkecambah, kecepatan berkecambah, tinggi tanaman umur (12, 28, 42 hst), jumlah cabang umur (28, 42, 56 hst), bobot segar brangkasan, bobot kering brangkasan dan bobot kering akar. Kata kunci : Cabai rawit, lama perendaman benih, frekuensi pemberian PGPR. Cayenne pepper is one of vegetables that have high economic value because it is almost always used in all kinds of dishes. Problems often encountered in the production of chili pepper cultivation is low because cultivation techniques have not been applied correctly. Strategy to increase growth and yield of pepper plants using PGPR. The purpose of the research is to determine the best time effect of soaking seeds chili by using PGPR, to determine the best frequency of PGPR, to determine the interaction of seed soaking time and frequency of PGPR on the growth and yield of cayenne pepper. The research was conducted in the Barang village, District Jumo, Temanggung on June to December 2014. The method used in this research is field trials method with complete randomized block design (RAKL) consisting of two factors and one control (Soaked in water for 1 hour). The first factor (L) seed soaking period consisting of three levels, namely L1 = 2 hours, 4 hours and L2 = L3 = 6 hours. A second factor (F) frequency of PGPR which consists of three levels of F1 = one week, F2 = two weeks and F3 = three weeks, with 9 combination treatment was repeated 3 times. The interaction on plant height parameters age 42 days after planting, the total weight of fruits per plant sample and the total weight of fruits per plot harvest. Combination treatment of soaking seeds with a frequency of PGPR give the best results at the age of 42 days after planting are height number of total fruit crop samples, the total weight of fruits per plant sample and the total weight of fruits per plot harvest. 6 hours of soaking seeds are best to influence germination, speed of germination, plant height age (12, 28, 42 days after planting), the number of branches of age (28, 42, 56 days after planting), fresh weight stover, stover dry weight and root dry weight . Keywords : Cayenne pepper, seed soaking period, the frequency of PGPR.
