Abstract

Shallots are vegetables that have high economic value. Shallots market demand in Indonesia increase over years in order to fulfil national consumption and exports. It is necessary to increase production by cultivating shallots in Utisol dry land which has low fertility and limited water availability. The fertilization with Salvinia molesta compost is an effort to increase the production and productivity of shallots in Ultisol dry land. This study aims were to investigated the effect of Salvinia molesta compost on the growth and yield of shallots, and to obtain the highest yield of Salvinia molesta compost. The study used a randomized block design (RAK) with one factor, the dose of Salvinia molesta compost were 0 ; 5; 10 ; 15 ; 20 ; and 25 tons ha-1. Each treatment was repeated four times. Salvinia molesta compost has no effect on growth, but is able to increase the yield of shallots. The dose of Salvinia molesta compost of 25 tons ha-1 resulted in the highest shallot bulb weight of 589.07 g m-2 (equivalent to 5.89 tons ha-1) an increase of 253.77% compared to the dose of 0 tons ha-1 (without Salvinia molesta compost).  Addition of Salvinia molesta compost up to a dose of 25 tons ha-1 still continues to increase tuber yields per m2.Keywords: organic matter, shallots, production

Abstract

Increasing production and productivity of shallots currently must be done by expanding the area of shallot planting. The expansion of shallot planting in Jambi is constrained by Ultisol land which has low soil fertility. This study aims to look at the response of shallots to the application of cow dung trichocompost doses, and to get a dose which will provide the most effective growth and yield of shallots. The research design used was a randomized block design (RBD) with one factor, namely the dose of cow dungtrichocompost consisting of: 0 tonha-1; 7.5 tonha-1; 15 tonha-1; 22.5 tonha-1; and 30 tonha-1. The results showed that the applying of cow dung trichocompost increased plant height, number of leaves, number of bulbs, tuber weight per clove, and bulb weight per clove of shallot. The dose of trichocompost that gave the most effective growth and yield was 22.5 tonha-1, with production 8.5 tonha-1dry bulbs, almost close to BimaBrebes production (9.9 tonha-1 dry bulbs), or 85.8% of the potential yield.Keywords: doses,production, response,Ultisol

Abstract

Okra (Abelmoschus esculentus L.) termasuk jenis sayuran yang memiliki nilai gizi dan ekonomi tinggi, sehingga sangat potensial dikembangkan di Indonesia. Mengingat masih terbatasnya ketersediaan benih okra maka perlu adanya upaya peningkatan produksi biji. Penelitian ini bertujuan untuk mengetahui pengaruh pemupukan nitrogen dan kalium terhadap pertumbuhan dan hasil biji okra, serta mendapatkan dosis yang memberikan pertumbuhan dan hasil biji okra tertinggi. Percobaan disusun dalam RAK dengan pola faktorial. Faktor I adalah dosis pupuk Urea (N 46%): 0 kg ha (0 gram per tanaman), 150 kg ha-1 (15,0 gram per tanaman). Faktor II adalah dosis pupuk KCl (K2O 60%): 0 kg ha (7,5 gram per tanaman), 300 kg ha-1 (2,5 gram per tanaman), 100 kg ha -1 (0 gram per tanaman), 50 kg ha-1 (10,0 gram per tanaman). Setiap perlakuan terdiri dari 6 tanaman dengan 2 tanaman sebagai sampel, dan masing-masing perlakuan diulang 3 kali. Hasil penelitian menunjukkan bahwa pertumbuhan dan hasil biji okra tidak dipengaruhi oleh interaksi pemberian pupuk nitrogen dan kalium, namun masing-masing faktor tunggalnya berpengaruh terhadap beberapa variabel pertumbuhan dan hasil biji okra. Dosis pupuk nitrogen 15 g per tanaman memberikan jumlah daun, jumlah buah per tanaman, bobot biji per tanaman, dan jumlah biji kecil tertinggi, serta mempercepat umur tanaman berbunga. Dosis pupuk kalium 7,5 g per tanaman memberikan tinggi tanaman dan diamater batang tertinggi, sedangkan dosis pupuk kalium 10 g per tanaman memberikan bobot biji per tanaman dan jumlah biji besar per tanaman tertinggi, serta mempercepat umur berbunga tanaman.
