one of the main problems in crop production in iran is the difference between actual yield and attainable yield which is called yield gap. thus, identifying yield constraints and yield gap are important. to do this, a study was conducted in 95 farms gorgan of in five villages, during two years 2007 and 2008. in this study, all of the information about management operations, soil and crop charac...

As the thermal variation may change total electron emission yield (TEEY) of materials and ultimately result in unexpected surface charging, it is necessary to study TEEY at various temperatures. In this research, we first updated measurement system with a newly designed sample stage for different temperatures (−50, 25, 100 °C) primary from 25 eV 10 keV. By using 30 μs/20 nA beam scanning method...

Prediction of the yield and quality of different types of cheeses that could be produced from a given type and/or amount of goat milk is of great economic benefit to goat milk producers and goat cheese manufacturers. Bulk tank goat milk was used for manufacturing hard, semi-hard and soft cheeses (N= 25, 25 and 24, respectively) to develop predictive formulae of cheese yield based on milk compos...

A study was carried out in mungbean Vigna radiata (L.) Wilczek) with eight ‘lines’ and four ‘testers’ crossed in a Line x Tester Genetic variability, heritability and genetic advance were estimated for marketable and its component yield traits in 48 lines of carrot (Daucus carota var. sativa L.). The study showed high ranges for total yield (3.15 -7.56 kg/plot), marketable yield (2.60 – 6.85 kg...
