A field investigation was run to ascertain the critical period of weed control in jute (Corchorus olitorius). The study consisted two distinct sets treatments, with one set weeds being left invade crop for a longer time, specifically, 15, 30, 45 and 60 days after sowing (DAS) up harvest. In other plants remained weed-free progressively periods, i.e., DAS, until reduction fibre yield (FY) record...

in this research, the chemimechanical pulps (cmp) with different yields were prepared by using the mixtures of constant raw materials comprising iranian hardwood species such as hornbeam (44%), poplar (31%), maple (15%) and salix (10%). this research was aiming to study cmp pulp properties variations in yields lower than standard limit (85%). four different yields (84, 80, 73 and 67%) were achi...

climate change phenomenon is an important environmental challenge of the world. increasing extension of greenhouse gases and remote relationship phenomena accelerate the speed f climate change. changes in precipitation level, drought occurrence and changes in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study consequences of clima...

A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping system at various combinations of organic manures and chemical fertilizers. The seed yield of inte...

New spectral methods for ratio cut partitioning and clustering. A general purpose multi-way partitioning, Proc. We introduced a new natural metric, Via-Count, to better estimate inter-partition delays for evaluating partitioning solutions. We presented K-VIA-FM, an algorithm that iteratively improve solutions for the new metric. We compared the performance of K-VIA-FM with other algorithms, bot...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (...

delaying bud break, using chemicals is an approach to avoid spring frost damage. therefore, the effect of spraying different concentrations of soybean oil and naphthalene acetic acid (naa) on delaying bud break, altering internal atmosphere and cold hardiness in grape cultivar ‘fakhri’ was studied in 2011 in a commercial vineyard in maryanaj, hamedan using a factorial trial based on randomized ...
