Keragaan Produksi Padi, Serangan Opt, dan Kondisi Mineral Tanah Pada Lahan Sawah pada Penerapan Budidaya Konsep Leisa dan Konvensional

Abstrak

Land resources for agriculture in Indonesia both dry land and wetland dominated by sick or troubled land . The production process in the conventional rice cultivation land use is very intensive , relying on the use of inorganic materials , and external input that results in a decline in health and quality of soil . The purpose of this study : to determine the production of rice plants cultivated with the concept of LEISA and conventional, pest attacks , and the condition of the mineral soil in paddy fields where the application of the concept of LEISA farming and conventional farming . The study was conducted in paddy fields in the village of Banjarrejo, Batanghari Sub-district, Lampung Timur District. Activities carried out in the first planting season of 2013 from March to August 2013 . Observations on two culture systems was conducted on the 10 member group of farmers who was apply the technology package and as a comparison taken 10 farmers who have not adopted the technology package . Observation parameters such as: production (ton ha-1), the intensity of important pests in both cultivation systems were calculated with absolute attack or attacks gradually . Analysis of soil minerals in Chemical Analysis Laboratory at the Polytechnic of Lampung. The results showed is known that the rice production technologies in the application package Low External Input Sustainable Agriculture (LEISA) is higher than the conventional rice cultivation . Intensity of some important pests in the cultivation of the concept LEISA lower than conventional farming, mineral soil condition at LEISA technology package despite an increase in status has not yet reached the ideal condition. Keywords: production, LEISA, important pests
