Oil constituents of European dill (Anethum graveolens L.) Affected by irrigation and FYM Levels and storage conditions

Abstract

A field as well as laboratory experiment was conducted to investigate the effect of irrigation and farmyard manure as well as storage conditions on oil constituents of European dill (Anethum graveolens L.). At field level, treatments viz., 4 levels of irrigation scheduled at 50 (I50), 100 (I100), 150 (I150) and 200 (I200) mm CPE and 3 levels of farmyard manure like 0 (F0), 15 (F15) and 30 (F30) t FYM ha-1 were conducted for two seasons from 2005-06 and 2006-07 in completely randomized blocks with 3 replications. In laboratory, oil was extracted from seeds stored upto 90 days and kept at cloth bag at room temperature, cloth bag in deep fridge, poly bag at room temperature, poly bag in deep fridge and oil constituents were determined by using Gas-liquid chromatography. Findings suggested that European dill may be irrigated at 100 mm CPE depends on rainfall and fertilized with 15-30 t FYM ha-1. Also, seeds may be stored for two months in polythene or polythene lined bags under room temperature without loss of oil quality
