Abstract

Abstract : The . - Client was carried out at the laboratory of the Department of Horticulture, Bangabandhu Sheika .:!)bur Rahman Agricultural University, Gazipur, during winter season (November 2005 to Ap “ ■ : 006) to assess the nutritional quality of spinach varieties planted at different dates, in the shallow Red-Brown Terrace Soil. Three varieties (Pusha, Rohini and All green) and three sowing dates (November 24, December 9 and December 24) were used as treatment variables. Just after harvest, crops were thoroughly cleaned and used for biochemical analysis. Sowing dates had no significant effect on nutritional quality of spinach. The amount of water content (%), dry matter (%), ascorbic acid and P-carotene were varied significantly due to varietal differences. Among the three varieties, Rohini resulted highest water content (93.52%) and maximum dry matter (7.39%) was produced by All green variety whereas, the Pusha variety contains the highest amount of ascorbic acid (49.18 mg/lOOg) and p-carotene (8.48 mg/lOOg).
