Effect of Immersion Time of Shallot Extract and Atonicon Seed Germination of Shallot

Abstract

The need for raw materials of fried onions derived from 'lembah palu Shallot tubers variety is high enough and can not be fulfilled, because the productivity is still low. This study aimed to find the type of plant growth regulator substances (PGR) with a long period of proper immersion to improve the germination of Shallot tuber. The research was conducted on Mei until June 2017 in Bulupontou Village, Sigi Regency. The study used two factorial Randomized Block Design (RBD). First factor of type RGS: (Z1) onion extract 100 g/l water, and (Z2) atonic 5 ml/l water. The second factor was long seed immersion in PGR: (T1)=30 min; (T2)=60 minutes; (T3)=90 minutes, and (T4)=120 minutes. Each treatment was represented 20 plants and repeated 3 times, so it was used 480 plants. The results showed that (i) red onion tubers soaked with Shallot extract 100 g/liter of water for 30-90 minutes yielded 100% Germinations, and tubers soaked in red onion extract for 30 minutes resulted in germination rate 31.3%/etmal, (ii) the type of growth regulator of shallot extract and atonic (PGR) effect was not significant on the germination of shallot; and (iii) the 30 minute long growth regulator immersion produced the highest hypothetical vigor index.

Keragaan Teknologi untuk Meningkatkan Produktivitas Bawang Merah Varietas Lembah Palu: Sebuah Review

“…Selanjutnya, Azwar et al, (2018) menunjukkan bahwa konsentrasi Atonik 2.0 ml L -1 air memberikan hasil terbaik terhadap pertumbuhan dan hasil tanaman bawang merah, dibandingkan dengan perlakuan lainnya. Selanjutnya, Bahrudin et al (2019) menemukan bahwa perendaman benih bawang merah pada zat pengatur tumbuh alami dan sintesis berpengaruh nyata terhadap perkecambahan tanaman bawang merah. Perendaman benih pada ekstrak bawang merah konsentrasi 100 g L -1 air selama 30-90 menit menghasilkan perkecambahan 100% dan indeks vigor lebih tinggi dari perlakuan lainnya.…”

Tropic soil properties and productivity of Shallot Lembah Palu variety

“…One of the famous superior commodities in the Palu Valley is the Palu Valley Variety Shallots. Shallots of the palu valley variety are the raw material of the fried shallot industry which is widely known by the public including those who visit the city of Palu both as local tourists and other guests [1][2][3] Shallots generally have wide adaptability and can grow and produce well to highlands in wet climates [4]. Unlike other IOP Publishing doi:10.1088/1755-1315/1253/1/012052 2 varieties of shallots, the Palu valley variety is found only in the Palu Valley and cannot adapt either in the midlands or in the highlands [2].…”

“…The low fertilization efficiency apart from being caused by soil properties that do not support also farmers' knowledge about the type of fertilizer, fertilizer dosage, application method and the right application time has not been well understood [8]. Various studies have been conducted to increase their productivity including treatment of seeds to improve quality, accelerate germination and growth of shoots [3,7,9].…”
