Physical, Chemical and Biological regulation of fruit characters and yield in Okra (Abelmoschus esculentus L. Moench).

Abstract

An investigation was carried out at Department of Olericulture, College of Horticulture, Vellanikkara, Thrissur during 1989-90 to study effect(s) physical, chemical and biological agents on fruit characters and yield in okra var. Pusa Sawani. Broadcasting and spaced plantings at 60 cm x 60 cm, 60 cm x 45 cm (control), 60 cm x 30 cm and 60 cmx 15 cm were thephysical treatments. Chemical treatments were NAA (15 ppm), 2-4-D (5 ppm), triacontanol (0.25 ppm) and CCC (1000 ppm) sprayed once at second node stage. Azospirillum culture from the Department of Microbiology, TNAU, Coimbatore and local strain of Azospirillum were used as biological agents for seed and soil inoculation. The experiment was conducted during four seasons; summer 1989, late kharif 1989, spring 1989-90 and summer 1990.
