Biocontrol of Phytophthora parasitica and Fusarium oxysporum by Trichoderma spp. in Hibiscus sabdariffa plants under field and greenhouse conditions

The efficiency of the biological control agent Trichoderma spp was tested against Phytophthora parasitica and Fusarium oxysporum in Roselle plants under field and greenhouse conditions. Under field conditions, three Trichoderma doses were applied to the base of the plant, and azoxystrobin and benomyl were applied at 30 and 60 days after planting. Also, 30 day-old plants were inoculated with 7 g of corncob/Trichoderma...

Straminipiles fungi growing on the alevins of the Nile tilapia in limnologically and trophically different water bodies

The authors investigated the growth of straminipiles fungi on the alevins of Nile tilapia (Oreochromis niloticus niloticus L.) in water from eight limnologically and trophically different water bodies. Twenty-seven species were recorded. The largest number of species occurred on alevins in water from the Biala River and Fosa Pond (more biogenic), and the fewest in water from Dojlidy Pond and Lake Blizno (poor in...

Influence of girdling and zinc and boron application on growth, quality and leaf nutrient status of olive cv. Frontoio

The experiment was carried out during 2008 to 2009 and 2009 to 2010 with the aim to study the effect of girdling and foliar application of zinc and boron on growth, quality and leaf nutrient status of olive cv. Frontoio. The experiment was laid out in a randomized block design with seventeen treatments. Maximum shoot extension growth (8.92 cm) was observed with the spray of 0.6% ZnSO4 in combination with 0.6% boric...

Optimization of pre-treatment conditions for maximum pulp recovery with optimum quality from bael fruit (Aegle marmelos Correa.)

The effect of pH, heating temperature, heating time and crude mass to water ratio on yield, total soluble solids and ascorbic acid content of pulp were studied. A central composite design was used to optimize the conditions of pulp extraction from bael fruit to maximize pulp yield, total soluble solids and maximum retention of ascorbic acid in pulp. The regression model describing the changes of pulp yield, total...

Sweet potatoes in Cameroon: Nutritional profile of leaves and their potential new use in local foods

Sweet potato (Ipomoea batatas) leaves especially the beta-carotene fortified varieties are rich in functional macro - and micronutrients such as dietary fibres, antioxidants and other micronutrients deficient in the predominantly starchy staples of most nutritionally vulnerable Africans. In this study, the nutrient content of young leaves and succulent green stems of local and exotic varieties were evaluated using...

Guidance of an agricultural robot with variable angle-of-view camera arrangement in cornfield

Guidance performances of an agricultural robot were evaluated when the robot traveled along cornrows and performed the row to row turning maneuver in cornfield with variable angle of view (AOV) camera arrangement. The arrangement with one low-cost camera has flexible AOV by controlling Servo motors motions as human vision. In this work, a forward far AOV was used to segment clearly and quickly cornrows due to more crop...

Ergonomic study of farm women during wheat harvesting by improved sickle

A study was conducted in Chandangaon village of Chhindwara district of Madhya Pradesh in 2009 to 2010 to determine the physical fitness, time and activity profile and physiological stress of farm women during wheat harvesting activity. A technically prepared serrated sickle was tested on farm women to improve work efficiency and to reduce the drudgery of women. The results revealed that 19.5% of working efficiency is...

Epidemiological study on foot and mouth disease in cattle: Seroprevalence and risk factor assessment in Kellem Wollega Zone, West Ethiopia

A cross-sectional study was conducted in three districts of Kellem Wollega Zone of Oromia Regional State, West Ethiopia between November, 2011 to March, 2012 with the objectives of determining the seroprevalence of foot and mouth disease (FMD) in cattle and assessing the potential risk factors associated with the disease. Antibodies against non-structural protein of FMD virus using 3ABC ELISA was measured as an...

Impact of climate change on grasses cultivation potential of three altitudinal strata-agricultural lands of Mexico

This study estimated the impact of climate change in the period 2040-2069 on six grasses potential areas in three altitudinal zones of México: 0 to1200 m (lowlands), 1200 to 2200 m (midlands) and >2200 m (highlands). Topography, soil and climate variables were used to depict potential areas. Climate data for  1961-1990 (reference climatology) and 2040-2069 were obtained from the WorldClim Earth System...

Effect of ultraviolet (UV) protectant added emamectin benzoate on codling moth (Cydia pomonella L.).

The efficacy of emamectin benzoate with ultraviolet (UV) protectant at different doses was compared with the emamectin benzoate for the control of codling moth on the apple trees at EÄŸirdir/Isparta and Çivril/Denizli during 2012. The types of treatments were control (water), the highest concentration of emamectin benzoate (0.20 g L-1) and different doses (0.12, 0.15, 0.17 and 0.20 g L-1) of emamectin benzoate...

Alleviating harmful effects of chilling stress on rice seedling via application of spermidine as seed priming factor

Chilling stress is a major limiting factor for rice production in many parts of the world. The study was carried out in the Seed Research Laboratory of the Department of Crop Science, Ferdowsi University of Mashhad in summer 2011. Rice (cv. Khazar) seeds were soaked in 50, 150 and 300 mg L-1 spermidine aerated solutions for 48 h and then dried back to the original moisture content and were sown in three temperatures...

Forage production, straw, structural characteristics and nutritional value of white oat in crop-livestock integrated systems

This study was aimed to evaluate the production of forage and residual straw, structural characteristics and nutritional value of white oat under different soil use in an integrated crop-livestock system. The experiment was conducted in the autumn–winter seasons of 2009, 2010 and 2011 using a randomized block design in a scheme of tracks. Six forms of soil were distributed in tracks and were used to cultivate...
