in order to study the effect of irrigation interval, n fertilizer and superabsorbent on yield and qualitative traits of sesame (sesamum indicum l.), a split-split-plot experiment was coducted in a farm in khusf of birjand, iran in 2009 on the basis of a randomized complete block design. the main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations were tested in this study: 5, 7.5...

For two consecutive years in Abbi, Delta State of Niger-Delta of Nigeria one, two and three beehives were integrated in oil palm plantation to determine optimum productivity of the oil-palm honey bee farming system. The fresh fruit bunch (economic yield) of the oil palm was statistically similar at 0, 1, 2 and 3 bee hive(s) per hectare. The honey yield were statistically similar for each bee hi...

Despite the importance of sesame (Sesamum indicum L.) in the world, this crop has received least research attention in Pakistan. Therefore, a field experiment was carried out to evaluate the performance of tillage system under various irrigation intervals and phosphorus levels on oil contents, yield and yield attributes of Sesame. The experiment was conducted at New Developmental Farm of the Un...

to determine the most suitable sowing date for rapeseed cultivars this study was carried out in busheshr agriculture research center, borazjan in 1997-1998 cropping season using a strip plot design with four replications. rapeseed cultivars were: global, regent, tower, pf7045/91, pf5045/88 and maluka which were sown on four different dates with fifteen days interval (oct.20, nov.5, no. 20 and d...

In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...

In this study, biodiesel production from microalgal oil by microwave-assisted transesterification was carried out to investigate its efficiency. Transesterification reactions were performed by using Chlorella protothecoides oil as feedstock, methanol, and potassium hydroxide as the catalyst. Methanol:oil ratio, reaction time and catalyst:oil ratio were investigated as process parameters affecte...

Evening Primrose oil (Oenothera biennis L.) is a rich source of Gamma linolenic acid (GLA) and other useful unsaturated fatty acids. Despite the diversity of sources of GLA, due to better absorption in the human body, evening primrose oil is the main source of GLA. In this study, the effects of pollination, harvesting method and application of salicylic acid on yield, yield components, and qual...

The most commonly used method for biodiesel preparation is via transesterification of vegetable oil using alkaline catalysts. Biodiesel yield and oil conversion are affected by operating conditions including the catalyst formulation and concentration. Application of alkaline catalysts can also lead to undesired soap formation. This study evaluated the alkaline catalyst effects on biodiesel yiel...
