Abstract:
Background and Objective: Lowland rice (Oryza sativa L.) is the staple food for most of Indonesian. Weed an important constraints in increasing rice production in Indonesia that has to be overcome. Weeds reduce the crop yield due to compete with light absorption, oxygen, CO2, space and nutrients. This study aimed to find out the weeds diversity in organic and conventional rice farming system in Purwakarta Regency west Java Indonesia. Materials and Methods: The materials used in this research were land map and questionnaire. The tools used in this research were squared meter (1.0×1.0 m), gauge, scissors, plastic bag, label paper, analytical scales and dryer oven. The method used was qualitative method (weed survey by giving questionnaires to farmers) and quantitative method by using vegetation analysis. This research was conducted from December, 2017 to February, 2018. Results: The vegetation analysis showed that weed diversity on conventional farming system consist of 3 species of grasses, 1 species of sedges and 5 species of broad leaf, whereas in organic farming system consist 2 species of grasses, 1 species of sedges and 4 species of broad leaf. Weeds with the highest SDR (Summed Dominance Ratio) value in both conventional and organic farming system is Fimbristylis miliacea. Conclusions: Weed population in conventional and organic farming system was different. This study can be useful to determine an effective and efficient post emergent wed management strategy for the following season.
