    MANAGEMENT OF WHITEFLY AND THRIPS IN MUNGBEAN WITH SOME SELECTED INSECTICIDES
    (DEPARTMENT OF ENTOMOLOGY, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA., 2014-12) ALAM, MD. SHAH
    The experiment was conducted at the central farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of March to May, 2014 to study the whitefly and thrips incidence in mungbean and their management. BARI Mung-5 was used as the test crop of this experiment. The experiment consists of the following treatments: T1: Nitro 505EC (Chloropyrifos + Cypermethrin) @ 2 ml/L of water at 10 days interval; T2: Casper 5SG (Emamectin Benzoate) @ 2gm/L of water at 10 days interval; T3: Voliam Flexi (Thiamethoxam + Chlorantraniliprole) @ 1.0 ml/L of water at 10 days interval; T4: Tapnor 40EC (Dimethoate) @ 2.0 ml/L of water at 10 days interval; T5: Allion 2.5EC (Lamda-Cyhalothrin) @ 1.0 ml/L of water at 10 days interval; T6: Admire 200SL (Imidacloprid) @ 0.5 ml/L of water at 10 days interval and T7: Control. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The lowest number of whitefly infestation per plant at vegetative (4.18) and reproductive stage (2.13) was recorded from T6 while the highest number of whitefly infestation per plant at vegetative (14.44) and reproductive (8.10) stage was recorded from T7 (Control) treatment. The lowest number of thrips infestation per 10 flower (1.88) was recorded from T6, while the highest number of thrips infestation per 10 flower (6.32) was recorded from T7 (control) treatment. The highest yield per hectare (1.53 ton) in T6 and highest benefit cost ratio (12.81) was found in T3 treatment, while the lowest yield per hectare (1.27 ton) in T7 (Control) and lowest benefit cost ratio (4.16) in T5 treatment. Admire 200SL (Imidacloprid) was the best effective among the management practices for controlling whitefly and thrips of mungbean which was followed by Voliam Flexi (Thiamethoxam + Chlorantraniliprole).

    SOIL AND GROUND WATER APPRAISAL OF LEVEL BARIND TRACT AND NORTH — EASTERN BARIND TRACT FOR IRRIGATED AGRICULTURE
    (HAJEE MOHAMMOD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR, 2007-06) ALAM, MD. SHAH; Dr. Bikash Chaniira Sacker
    A study was conducted to assess the quality of the soil and groundwater collected from three thana of Dinajpur district in Bangladesh. 55 water samples and 15 soil samples were collected from different locations for chemical analyses. The standard parameter were pH, EC, TDS, Hr, Ca, Mg, Fe, Mn, Cu, Cl, HCO3, CO3. SO,4, NOs, etc. The pH value indicated that the water was all most neutral to slightly alkaline. Grading based on B and SSP reflected that all water was good to excellent classes. Rating on TDS and SAR categorized the water as excellent. In respect to hardness, water was moderately hard to soft class. All water was free from RSC and belongs to the suitable category. EC and SAR revealed that water samples were medium salinity and low alkalinity nature and was expressed as C,S;. Other micronutrient like Fe, Zn, Mn and Cu were within the safe limit for irrigating all types of agricultural crops. According to drinking standard, some of the water was detected due to higher concentration of Fe and Mn ions. Other pollutant likes Cl, Cu, Zn and SO, were within the safe limit. The soil of the Dinajpur district was slightly acidic in reaction. The increasing tendency of EC in soil of the study area might lead to soil salinity problem in future. The concentration of P, S, Ca, Mg, Na, K, Na, Fe, Zn, Mn and Cu increased significantly. Organic carbon and total nitrogen exhibited slight or no remarkable change due to longterm irrigation.
