    EFFECT OF DIFFERENT LIMING CONDITIONS ON ROOT GROWTH, YIELD AND PROTEIN CONTENT OF SUMMER MUNGBEAN
    (HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2010) MUSTARY, SHOBNOM; Dr. Bikash Chandra Sarker
    A field experiment was carried out to investigate the root growdi and yield potential and protein content of summer mungbean under different levels of lime. Different doses of dolomite (CaCoa-MgCos) lime are used for liming materials (T,- 0 kg lime ha'', 500 kg lime ha', T3= 1000 kg lime ha'', T4= 1500 kg lime haT5- 2000 kg lime ha'', Ts- 2500 kg lime ha*', T7= 3000 kg lime ha ', T8= 3500 kg lime ha''). The highest number ofleafnumber plant' (23.4) found in followed by T5, T3, T4, T7, T4, and Tg mungbean plants at 50 days after sowing (DAS). The lowest leaf number plant’' was (17.5) found in Ti mungbean plant. The tallest plant height (38.23 cm) was found in Tg at 50 DAS followed by T4, Tj, T7, T|, T^ and T3 and the lowest height was (28.47 cm) originated in T2, at 40 DAS. The leaf surface area was 71.5 cm^ in Te plant while the lowest was 52 cm^ in Ti plant at 45 DAS. The T7 plant showed significantly greater effect on root dry weight and root length while the lowest was in control plant for both cases. Root weight, length as well as root volume markedly increased under liming conditions. The number of root nodule plant'' was found statistically significant. Liming effect on the number of seed pod'' was found statistically significant. The highest number ofseed pod'' (12.3) was found in Tg similar to that of T4, T5, T? and Tg plants. The lowest number of pod plant'' (9.56) was found in Ti. Liming effect on grain yield was found statistically highly significant. The highest grain yield (1635.3 kg ha') was found in T5 similar to that of T7 and Tg. The lowest grain yield (1505.8 kg ha ') was found in Ta. Liming effect on dry biomass plot' was found statistically significant. The protein content in seed was 25.05 to 26.35%. There was no significant influence oflime on protein content in mungbean seed in the present study. This study infers that lime application at the rate of 2000 kg ha"' is recommended for the study area for better root growth and higher yield in summer mungbean.
