DEVELOPMENT OF LOCAL GREEN SPINACH PLANTS BY APPLICATION OF NUCLEAR PHYSICS METHODS (STANDARD MULTI-GAMMA IRRADIATION)

Abstract

This research aims to develop local green spinach with the application of nuclear physics to obtain a superior cultivar that adapts to dryland conditions, is tolerant of pests and diseases, and has high production. This research use irradiation, observation, sampling, careful selection, purification, comparative, and interpretation as the methods. Research procedures: 1) preparing samples, 2) land preparation, 3) sample irradiation at a dose of 2000 rads for 30 minutes, 4) equality of samples that have been irradiated, 5) when the plants were one week old, the spinach seedlings were transferred to a different area has been prepared with a spacing of 50 cm × 30 cm for pickled spinach, 6) weeding and fertilizing spinach plants as needed, 7) careful selection (individual selection), 8) harvesting after planting spinach is approximately 2-3 weeks old for commercial purposes, 9) maintaining several tree crops spinach that will use as seeds for further development, 10) harvesting, cleaning, and store in foil bags to avoid pests, 11) determining the nutritional content of spinach leaves with an analytical service model. The results showed that the development of local green spinach plants by application of nuclear physics methods (multi-gamma irradiation) produces a superior cultivar of local green spinach that is adaptive to dryland conditions, tolerant of pests and diseases, and production significantly increases. The range and average output of superior cultivar of local green spinach irradiated by multi-gamma were 4.86-5.46 t/ha and 5.25 t/ha, with a percentage increase in production of 38.29 %.
