Pengaruh Pemotongan Umbi Dan Pemberian Beberapa Dosis Pupuk Npk Majemuk Terhadap Pertumbuhan Dan Hasil Tanaman Bawang Merah (Allium ascolanicum L.)

Abstract

Implementation of good cultivation systems can improve onion (Allium ascalonicum L.) yield. The purpose of this study was to determine the effect of tuber cuttings and the dose of NPK fertilizer on the growth and yield of onion. The experimental design was factorial randomized block design arranged consisting of two factors. The first factor was tuber cuttings which consists of without and with ¼ and 1/3 cut; the second one was dosage of NPK fertilizer which consists of without and with 200 kg/ha; 400 kg/ha; 600 kg/ha. There are 12 combinations of treatments, each of which is repeated three times. The results showed that there was no interaction effect between tuber cutting and NPK dosages on growth and yield of onion. independent effect of tuber cuttings and NPK dosages also didn’t inflence both parameter. Tuber cuttings only increase pant height at one and two weeks after planting. Overall, cutting-quarter of the tuber could induce better fresh weight and dry weight of tubers although statistically didn’t significant.

The Effect of Various Types of Mulch on the Growth and Yield of Dayak Onions (Eleutherine palmifolia (L.) Merr)

“…But in the research of Fauzi et al (2016), using silver black plastic mulch in onion cultivation produced more leaves than mulch and without mulch. Fatmawaty et al (2015) said that the vegetative growth activity of plants can be indicated by the parameter number of plant leaves. Leaf formation itself is influenced by the genetic traits of plants but can be accelerated by a good growing environment.…”

Agronomic characteristics and shallot production in Tomohon city, North Sulawesi

“…Potassium is indispensable for the process of photosynthesis process and can increase the weight of shallot tubers [20]. Furthermore, Fatmawaty et al [21] the provision of NPK compound fertilizer can affect the increase in shallots' growth and yield and increase crop yields. According to Asrijal et al [22], the growth and production of shallots are influenced by the potential and quality of seeds or seeds sourced from various types of varieties.…”

Respons Tanaman Bawang Merah Terhadap Pemberian Pupuk Organik Cair Air Kelapa dan Mikroorganisme Lokal Bonggol Pisang

“…Faktor yang kedua adalah pada usia 8 MST atau 56 HST ini menurut Pusat Penelitian dan Pengembangan Hortikultura (2020) sudah memasuki fase pematangan umbi bukan lagi fase vegetatif. Hal tersebut sejalan dengan pendapat Fatmawaty et al, (2015) yang menyatakan, umur pemanenan tanaman bawang merah yang dimulai sejak 60 HST atau apabila dikalkulasikan berkisar antara 8 sampai 9 MST itu tidak akan mengalami pertumbuhan dan juga penurunan atau konstan.…”

“…Jumlah rata-rata daun belum sesuai dengan deskripsi tanaman, terlepas dari faktor utama perlakuan yang diberikan yaitu air kelapa dan MOL bonggol pisang sebenarnya daun terbentuk dipengaruhi oleh beberapa faktor. Fatmawaty et al, (2015) mengemukakan bahwa pembentukan daun pada tanaman dipengaruhi oleh faktor internal yaitu genetik dari tanaman itu sendiri, tetapi faktor eksternal yaitu lingkungan yang mendukung dapat membantu untuk mempercepat pembentukan daun.…”
