Abstract

A field experiment was conducted for two successive seasons (2015/2016 and 2016/2017) on globe artichoke (Cynara scolymus L.) cv. Fransawy in a randomized complete block, factorial. Factor 1 was manuring (M) treatments of mineral nutrients “ as a reference treatment” “RT” (M1), farmyard manure “FYM” (M2), vermicompost “VC” (M3), chicken manure “CM” (M4) and biogas compost “BC” (M5). Factor 2 was Arbuscular mycorrhiza (A) with treatments of none (A0) and mycorrhiza (A1). Mineral fertilizations (kg ha-1) were 124 N+65 P+200 K. Organic fertilization was on basis of applying 124 kg total N ha-1 of each source with the associated P and K in each. Rates of sources (kg ha-1) were 34972.1 FYM, 4124.6 CM, 6887.9 BC and 7614.9 VC (as an average in both seasons). RT gave greater values of number of leaves, number of off-shoots, plant height as well as NPK contents and yield than any of the organic manures with relative yield production efficiency of 80.9, 76.7, 68.2 and 66.7 % for VC, CM, FYM and BC respectively relative to RT. Vesicular Arbuscular Mycorrhizal (VAM) caused increases in all parameters only under conditions of organic manuring.
