Seed germination, seedling mortality and subsequent growth of Albizia procera seedlings were studied. Seeds were treated with hot water of 50° and boiled water of lOO°C for three minutes and compared against the untreated seeds soaked in cold water. It was observed that the germination per cent was higher and mortality was lower in the case of untreated seeds. Root/shoot ratio oflength and biomass were not different among thOse seeds. The overall performance was found better in the case of untreated seeds though there was a little advantage in shoot length and ischolar_main length in the case of lOO°C treated seeds.

Growth of crops obeys certain physiological principles, which have been described, most of the times, in qualitative terms but can be quantified in response to the environment by mathematical formulae by linking the equations to each other. In process, a mathematical model is obtained that can be written as a computer program. Rapid accumulation of knowledge in the agricultural fields and increased accessibility to information technology have contributed to the development of a wide number of agricultural models. Crop simulation models can be used as a tool to assist farmer in their decisions on agronomic and management operations.Full Text

A field experiment was conducted during the 2016-17 mango cropping season in farmers’ fields of Gazipur, Rajshahi and Chapainawabgonj districts of Bangladesh to find an effective bio-rational management option for controlling the mango hopper, Idioscopus nagpurensis (Pruthi) (Hemiptera: Cicadellidae). Randomized Complete Block Design was used incorporating 8 treatments with 3 replications. The treatments were pruning of overcrowded and overlapping branches, spraying of azadirachtin, Beauveria bassiana (Lycomax, Russel IPM), imidacloprid insecticide, installation of yellow sticky grey and blue sticky trap and untreated control. Lowest leafhopper population was recorded in B. bassiana (3.0 hoppers/sweep/tree) followed by imidacloprid (3.7 leafhoppers/sweep/tree) treatments. Highest number of fruit retention was recorded in imidacloprid (40.00 fruits/20 inflorescence/tree) followed B. bassiana (32.67 fruits/20 inflorescence/tree) and azadirachtin (24.00 fruits/20 inflorescence/tree). Imidacloprid treatment offered maximum marginal benefit cost ratio (5.60). Increasing trend of hopper population was recorded in control. Considering health and environment issues, spraying of B. bassiana @ 5.0g/L of water at flower initiation stage, flowering stage and pea stage may be recommended for controlling mango hopper.Keywords

The experiment was carried out in farmers’ fields of Chaklarhat, Tunirhat, Panchagarh and Research Field of Horticulture Research Center, Bari, Gazipur from October 2017 to June 2018 to findan effective and suitable management approach against tomato leaf miner, Tuta absoluta. There was a total of ten treatments, viz., Treatment 1 = Application of Metarrhizium anisolpiae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water, Treatment 2 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water), Treatment 3 = Foliar spray of Bacillus thuringiensis (Biocure) @ 2g/L of water, Treatment 4 = Mass trapping through installation of delta sex pheromone trap, Treatment 5 = Spraying of spinosad (Tracer 45WSC) @ 0.5ml/L of water, Treatment 6 = Spraying with chlorantraniprole (Coragen 20SC) @ 0.5ml/L of water, Treatment 7 = Hand picking and destruction of infested leaf and fruit, Treatment 8 = Foliar spray of B. thuringiensis (Biocure) @ 2g/L of water + mass trapping through installation of delta sex pheromone trap + application of M. anisolpiae biopesticide in soil @ 5g/L of water, Treatment 9 = Foliar spray of azadirachtin (Bio-Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + Application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water and Treatment 10 = untreated control were evaluated against T. absoluta following RCB design with three replications. Results revealed that foliar spray of azadirachtin (Bio- Neem plus 1EC @ 1ml/L of water) + mass trapping through installation of delta sex pheromone trap + application of M. anisopliae (Lycomax, Russel IPM) biopesticide in soil @ 5g/L of water performed best in reducing T. absoluta infestation, increase of marketable yield and highest marginal benefit cost ratio.Keywords
