Seed Production Potentiality and Viability Improvement of Eryngium. Seed Production Potentiality of Bangladhonia (Eryngium foetidum L.) Influenced by Plant Growth Regulator and Population

      Аннотация: Bangladhonia (Eryngium foetdum L.) is a highly priced aromatic and medicinal culinary herb increasingly cultivated world wide. Seed - its production, rapid viability degradation and low germination rate limits its dissemination and cultivation. Experiments were conducted by the author at the Horticulture Field Laboratory of BSMRAU, Bangladesh to study morphology, fresh herb and seed production potentiality, seed storage and viability improvement. The dissertation includes method of Eryngium cultivation, morphological study, fresh herb and seed production, seed storage, viability and germination enhancement using growth regulators with different plant spacing. The highest seed yield (136.3kg/ha), gross return(BD Tk. 0.75 million/ha) and BCR (4.76) was recorded in 10?10 cm plant spacing. Seed treated with growth regulator solution (GA3 500ppm + Kinetin 50ppm) gave the maximum germination (31.23%), fresh yield (55.90 t/ha), gross return (BD Tk. 1.37 million/ha), gross margin (BD Tk. 1.18 million/ha) and BCR (8.52) with 20 kg seed/ha in broadcasting sowing system. Low temperature (4-5 deg.C) storage with air tight sealed polyethylene bag packaging was found better for storage of seeds.
