Respon Pertumbuhan dan Hasil Tanaman Bawang Merah (Allium Cepa L.) Varietas Bima Brebes Akibat Pemberian Pupuk Organik Teknologi Nano

Abstract

The development of organic fertilizer technology continues to advance in order to achieve 
optimal shallot production. The use of nano-technology organic fertilizer can help reduce the 
dependence on chemical fertilizers, as its nano-sized particles enable faster nutrient 
absorption and enhance nutrient retention within plant tissues, thereby minimizing nutrient 
losses through volatilization or leaching. This study aimed to determine the optimum 
concentration of nano-technology organic fertilizer that provides the best effect on the growth 
and yield of Bima Brebes shallot (Allium cepa L).The experiment was conducted at the KO 
Diklat Complex, Bumiwangi Village, Ciparay District, Bandung Regency, West Java, 
Indonesia, at an altitude of 701 meters above sea level. The experimental site receives an 
average annual rainfall of 2,430.7 mm and is classified as Oldeman C3 rainfall type. The study 
was carried out from March to July 2025.The research employed an experimental method 
using a Randomized Complete Block Design (RCBD) consisting of six treatments and four 
replications. The treatments consisted of different concentrations of nano-technology organic 
fertilizer: A (0 mL L?¹), B (1 mL L?¹), C (2 mL L?¹), D (3 mL L?¹), E (4 mL L?¹), and F (5 mL 
L?¹).The results showed that treatment F (5 mL L?¹) was the optimum concentration, producing 
the highest growth and yield in most of the observed parameters, particularly fresh bulb weight 
per clump and fresh bulb weight per plot, which are the primary indicators of shallot 
productivity.
