cumin is an annual plant suitable for dry and semi-dry regions. it is harvested at two stages to prevent seed shedding. first, the cumin bushes are harvested by hand or using a scythe. after drying, the cumin bushes are beaten with a stick or trampled using animals or a small tractor. this harvesting method is time consuming, requires intensive labor and is an incomplete threshing process resul...

since threshing is one of the most sensitive rice post-harvest processing operations, this study was conducted to evaluate the threshing performance in axial - flow paddy thresher. independent variables consisted of: drum speed at five levels (550, 650, 750 and 850 rpm), equivalent to peripheral velocities of: 14.67, 17.35, 20.01 and 22.37 m/s, respectively, paddy moisture content at two levels...

The aim of this work was to evaluate two operating parameters of seed drying (temperature and initial moisture content) on the tocopherol content of canola oil. The raw material was characterized by moisture, oil, protein, crude fiber and ash content. Seeds at 13.6% and 22.7% moisture content (dry basis, db) were dried at temperatures in the range of 35-100 °C to a safe storage moisture of 7% d...

This study was carried out to appraise whether or not the exogenous application of a potential osmoprotectant, proline, could ameliorate the adverse effects of drought stress on maize seed and seed oil composition, as well as oil antioxidant activity. Water stress reduced the kernel sugar, oil, protein and moisture contents and most of the seed macro- and micro-elements analyzed in both maize c...

Research has been on-going on many plant materials, especially those discarded as waste, to exploit their nutritional and antinutritional properties. This is as a result of the United Nations’ millennium development goal to eradicate extreme poverty and hunger. Avocado (Persea americana Mill) seeds are often discarded after taking the pulp of the fruit. This study is aimed at evaluating the eff...

in order to study the interrelations of photosynthetic rate and surfaces and leaf proline content with yield and yield components of safflower under different irrigation regimes, a field experiment in a split plot arrangement under a ranomized complete block design with four replication was performed at lavark reasrch farm, isfahan university of technology, isfahan, iran in 2007. two irrigation...
