Influence of two maturation stages and three irrigation regimes on Chétoui olive oil quality

  The effects of three-irrigation managements (50% evapotranspiration [ETc], 75% ETc and 100% ETc) and two-maturation degrees (maturation I and maturation II) on the quality on Chétoui olive oil were evaluated. The following parameters were monitored: Pomological parameters, free fatty acids, peroxide value, total phenols, bitterness intensity, oxidative stability, fatty acid composition and...

Prediction of water quality parameter in Jajrood River basin: Application of multi layer perceptron (MLP) perceptron and radial basis function networks of artificial neural networks (ANNs)

  River water quality is a significant concern in many countries, considering agricultural and drinking consumptions. Therefore, prediction of salinity index, as the main water quality condition is a necessary tool for water resources planning and management. This paper describes the application of artificial neural networks (ANNs) models for computing the total dissolved solids (TDS) level in Jajrood River...

Effects of feed withdrawal periods of different durations on the growth performance of male Hybro broiler chickens

  The effects of feeding Hybro broiler chickens ad libitum (control), 6 days/week, 5 days/week or every other day from 7 to 35 days of age followed by full feeding to 49 days of age was investigated. During the feed removal period, the control birds consumed more feed, gained more weight and were heavier at the end of the period than the feed-restricted birds. The birds whose feeding periods were...

Assessment of factors affecting the farmer demand for seed potato in Nakuru District, Kenya

  The potato sector in Kenya has been hampered by inadequate use of certified seed mainly due to inefficient delivery of quality seed in the right quantities. This study aimed at estimating the farmer demand for seed as well as analysing the structure, conduct and performance of the seed market. A total of 250 farmers and 36 fertiliser traders were interviewed between February and April 2001, using systematic...

Factors affecting proportions of land allocated to the mini-sett technology by yam producers in Northern Ghana

  The study investigated factors affecting proportions of land allocated to the yam mini-sett technology among 120 randomly selected farmers in Northern Ghana. About 41% of the farmers allocated about 33% of their yam land to the technology. Results from the Tobit regression model suggest that the dissemination of the technology must also target farmers who are non-natives, household heads, less...
