Study on the effect of growth regulators and the concentration of coconut water on the growth and yield of garlic shallots (Allium ascalonicum L.)

Abstract

An investigation on the influence of Atonic Growth Regulatory Substances and coconut water immersion on the growth and yield of shallots was conducted from March 3 to May 9 in 2023, in Tawangrejo Village, Ngrambe, Ngawi. The objective of this study is to analyze the impact of different doses of ZPT Atonik and coconut water on the growth and yield of shallots (Allium ascalonicum L). The experiment was designed using a Completely Randomized Block Design (RAKL), which included two factorials. The first factorial was the level of coconut water immersion concentration (K), consisting of four levels, namely K0 = 0%, K1 = 80%, K2 = 90%, and K3 = 100%. The second factor in this study is Atonik (A), which consists of four levels: A1 = 0 ml/l, A1 = 1.5 ml/l, A2 = 3.0 ml/l, and A3 = 4.5 ml/l. Each experiment in this study will be repeated three times and comprise four treatment levels, resulting in a total of 16 treatment combinations. We analyzed the data using Analysis of Variety followed by the Honest Significant Difference Test (BNJ) at the 5% level. The study results revealed that the Atonik treatment and coconut water immersion did not have a significant effect on the observed parameters of the number of leaves (40.30), number of tubers (17.87), tuber diameter (2.45 cm), fresh weight (130.63 g), and dry weight (109.22 g), but had a significant effect on the observed parameter of plant height (41.33 cm).
