Analisis Pertumbuhan Tanaman Sawi Caisim (Brasicca juncea L) Akibat Pemberian Dosis Dan Cara Aplikasi Pupuk Urea

Abstract

Mustard caisim (Brassica juncea L) is one of the horticultural crop commodities from a type of vegetable that is used for its young leaves, as vegetable food and has various benefits and uses. In everyday people's lives. Apart from being used as a food ingredient, mustard greens can also be used for treatment to obtain good plant growth results. Research requires proper dosing and application methods. This study aims to determine the interaction of fertilizer dosing and how to apply urea fertilizer on the growth and yield of mustard plants. The research design was prepared using a randomized block design with control, the study consisted of two factorials which were presented as follows: Control, A₁D₁ : doubled + 50kg/ha urea fertilizer dose, A₁D₂: doubled + 100kg/ha urea fertilizer dose, A₁D₃: doubled + urea fertilizer dose 150kg/ha, A₂D₁: leaked+ a dose of 50kg/ha urea, A₂D₂: leaked+ a dose of 100kg/ha urea, A₂D₃: leaked+ a dose of 150kg/ha urea. The results of this study showed that the combination of dosing and application of urea fertilizer gave good results on several plant parameters such as plant fresh weight of 51.30 g with an optimum dose of 100 kg/ha by leaking application and plant fresh weight of 43.02 g with The optimum dose is 130 kg/ha by single application
