Jute is one of the most important crops in Bangladesh and its quality, to a great extent, depends on the system used for drying the fibre. In this study, a solar drying system for jute fibre is developed in order to improve the quality of raw-jute and jute products. A thorough review of existing literature is presented in order to exhibit the current state-of-art of fibre drying. The solar energy availability is reviewed also in the context of Bangladesh. The theoretical and experimental investigations of different solar air collectors used as solar air heaters are carried out. The...

In this present era of Genomics, the genomes of many different organisms or plant species are already sequenced and some are being sequenced. As a result,a huge repository of unknown genes or genes with unknown functions has developed and functional genomics has to deal with the problems of such unknowns . We have constructed a novel VIGS vector,using the minimal replicon region of the DNA-A component of the geminivirus, Mung bean Yellow Mosaic India Virus (MYMIV). The vector is incorporated between the left and right border region of standard pCAMBIA vector so that the recombinant vector...

A field experiment was done at SAU Farm, in winter(10 Nov. 2004-07 Mar.2005)to investigate the effect of vermicompost and NPK (Nitorgen+Phosphorous+Potassium) on the growth, chemical composition and yield of wheat. The experimental soil was silty clay, pH 6.0. The treatments were 4 levels of vermicomposts viz. V0 (0 t ha-1), V1 (1 t ha-1), V2 (2 t ha-1), V3 (3 t ha-1), and 4 levels of fertilizers viz. F0 = (0-0-0 kg ha-1), F1 = low (40-30-20 kg ha-1), F2 = medium (80-60-40 kg ha-1), F3 = high (120-80-60 kg ha-1) of N-P2O5-K2O with 16 treatments combinations and 3 replications. The results...
