A field experiment was carried out at the Agronomy Field of Bangladesh Agricultural University, Mymensingh, during the period of March to June 2010 to study the effect of variety and date of harvest on the performance of summer mungbean. The experimental treatment includes (i) 3 varieties viz. Bina Mung 5, Bina Mung 6 and Bina Mung 7; (ii) 3 date of harvest viz., One time harvest (H₁) = when 80% pods became matured, Two times harvest (H₂) = when 50% pods became matured + when 70% of the rest pods became matured and Three times harvest (H₃) = when 50% pods became matured + when 70% of the rest pods became matured +when 80% of the rest pods became matured. The experiment was laidout in a randomized complete block design with four replications. Results revealed that variety and date of harvest had significant influences on various crop characters and seed yield. The varietyBina Mung 7 showed superiority in plant height, number of branches plant⁻¹, number of effective pods and total pods plant⁻¹ and number of seeds pod⁻¹ over other two varieties resulting in highest seed yield of 1856 kgha⁻¹. Among the harvesting date treatments, H₃ (three times harvest) was superior in relation to number of branches plant⁻¹, number of effective and total pods plant⁻¹, number of seeds pod⁻¹, 1000-seed weight and plant population per m² compared to H₁ and H₂ treatmentswhich resulting the highest seed yield of 1792 kg ha⁻¹. In case of interaction effect of variety and date of harvest, V₃H₃ treatment combination showed superiority in crop characters and yield attributes and yield (1950 kg ha⁻¹) of summer mungbean variety than any other treatment combinations.
