Defect parameter extraction plays an important role in process control and yield prediction. A methodology of evaluating wafer level defect clustering will be presented to detect equipment specific particle contamination. For that, imaginary wafermaps of a variety of different chip areas are generated to calculate a yield-to-area dependency. Based on these calculations a Micro Density Distribut...

The mutagenic effect of gamma rays, ethyl methane sulphonate (EMS) and sodium Azide (SA) used either singly or in combination were observed for induced genetic variability for yield and yield traits in M and 2 M generation in the two cultivars of Basmati rice. The observation mean range and coefficient of variation (CV) 3 suggest that the mutagen treatment had wider values than the control. The...

Year-to-year variations in crop yields can have major impacts on the livelihoods of subsistence farmers and may trigger significant global price fluctuations, with severe consequences for people in developing countries. Fluctuations can be induced by weather conditions, management decisions, weeds, diseases, and pests. Although an explicit quantification and deeper understanding of weather-indu...

Field studies with and without Bradyrhizobium was carried out with five mungbean varieties to observe the yield and yield attributes of mungbean. Five mungbean varieties viz. BARI Mung-2, BARI Mung-4, BARI Mung-5, BINA mung-2 and Barisal local, and the rhizobial inoculum (Bradyrhizobium strain BAUR-604) were used. The seeds and stover were dried and weighed adjusting at 14% moisture content and...

A study was conducted to evaluate the seasonal influence on yield and yield contributing characters of four lablab bean genotypes: IPSA Seam-1, IPSA Seam-2, BU Seam-3 and JER during September 2000 to December 2001 covering one main season (winter) and two off-seasons (early summer and late summer). Compared to off-seasons, all the genotypes performed better for all the parameters during winter....

Recurrent drought and late blight disease are the major factors limiting potato productivity in the northwest Ethiopian highlands. Incorporating drought tolerance and late blight resistance in the same genotypes will enable the development of cultivars with high and stable yield potential under erratic rainfall conditions. The objectives of this study were to assess combining ability effects an...

Twelve cultivars of bambara groundnut were sown for evaluation of variability and genetic correlation among agronomic characters and seed yield in 2004 and 2005 in a randomized complete block design with three replications. Combined analysis of variance revealed highly significant effects (p<0.05) for genotypes (G), year (Y) and G x Y interaction for most characters evaluated. Estimates of geno...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to assess the effect of weeding on growth, yield and yield contributing characters of mungbean (Vigna radiata L.) cv. BINA mung4 during October 2011 to February 2012. The experiment was laid out in a randomized complete block design with four replications. The trial comprised seven tre...

The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

Background & Aim: The genus Satureja belonging to the family of lamiaceae and consists of over 235 different species throughout the world. Fourteen species grow naturally in IRAN of which eleven species are endemic. Different species of Satureja are used in food, Healthy, cosmetic and medical industry. This reseach has been carried due to selection and introduction of...
