A pelletized feed production unit to cater the need of nutritionally balanced, optimally processed, cost and time effective availability of feed for livestock /aqua farming may be adapted as a potential business enterprise. ... -
Mechanized Harvesting of Leafy Parsley Crops in the Region of South Banat
So far, many types, styles and sizes of mowing equipment has been developed and introduced in the agricultural practice. Therefore, leaf crops harvesting seems to be easier to mechanize with respect to other cultivars. ... -
Theoretical and Experimental Research of Strength of Soldered Joints (Metal of Share – Metal Ceramics)
This article presents theoretical estimate of soldered strain and the obtained equivalent stresses distributions along the share length. It is suggested to estimate the soldered joints strength taking into consideration ... -
Results of Preliminary Laboratory Studies After Pre-Sowing Electric Treatment of Pea Seeds
In many countries, the possibilities for stimulation of the sowing qualities and yield of cultivars after pre-sowing electric treatment of their seeds have already been identified. At the University of Ruse, Bulgaria, ... -
Respiratory Behaviour of Mature Light Green Guava (Psidium Guajava L.) under Closed System
Respiratory behavior is an important aspect in designing and operating systems such as controlled and modified atmosphere storage that will extend the shelf life of the perishable produce. The respiration rate and respiratory ... -
Development of Air Assisted Sprayer for Greenhouse Floriculture Crops
Floriculture is one of the major sectors in Indian agriculture. Main threats to floriculture production are insects, pests and diseases. Therefore, a motor operated air assisted sprayer was developed for greenhouse ... -
Acute Oral Toxicity Study of GAL-57 (Bentazon + Dicamba) Herbicide in Rats
An acute oral toxicity study of the herbicide GAL-57 (Avalon), a mixture of bentazon and dicamba as active ingredients, was investigated on rats, using a new method that has been used in the past several years (2001). Clinical ... -
Development and Comparative Study of Cast Iron Rasp Bar and Nylon Rasp Bar Threshing Cylinders for Paddy Threshing
Two types of threshing cylinders, namely cast iron rasp bar threshing cylinder and nylon rasp bar threshing cylinder, were developed and fitted with portable paddy thresher. Each threshing cylinder was tested for its ... -
Effect of Feed Rate, Concave Clearance and Peripheral Speed on the Performance Evaluation of Pre Thresher for Onion Umbels (Allium cepa var. aggregatum L.)
Freshly harvested, sun dried onion umbels consists of florets attached to the hard umbel heads. Conventional threshing method involves tractor treading, rubbing umbels using rubber slippers on hard surface and beating with ... -
Application of Cooling in Postharvest Handling of Grain
The present paper addresses the issue of postharvest handling of grain with focus on storage, when cooling is used in order to maintain the quality of the processed product and the required storage period. The paper presents ... -
Naturally-Occurring Entomopathogenic Fungi on Three Bark Beetle Species (Coleoptera: Curculionidae) in Bulgaria
Bark beetles (Coleoptera: Curculionidae: Scolytinae) belong to one of the most damaging groups of forest insects and the activity of their natural enemies – pathogens, parasitoids, parasites or predators suppressing their ... -
Efficacy of Different Lambda-Cyhalothrin Formulations against Ticks
Ticks (Acari:Ixodida) are arthropods of special biomedical importance, well known as transmitters of several zoonotic diseases. Various acaricides have been used to control them but their number has decreased over the ... -
In vitro Toxicity of Fungicides of Different Mode of Action to Agaricus bisporus (Lange) Imbach
Isolates of Agaricus bisporus strains F56 and U3 were tested for sensitivity to several selected fungicides in vitro. The analysis showed that flusilasole + carbendazim and cyproconazole + carbendazim were the most toxic ... -
Health Constraints in Fish Farming in the Mediterranean
Culture of warmwater aquatic species in the Meditaranian region has sustained continues growth through the past 20 years. There are many reasons for the sustained growth of the industry in this region, including advances ... -
Preliminary Results on the Phytophagous Insect Fauna on Onopordum acanthium (Asteraceae) in Bulgaria
The Scotch thistle, Onopordum acanthium (Asteraceae) has the Eurasian origin and represents an invasive weed in the USA and Australia. It is a serious problem in pastures, along roadsides, rangeland, etc. The weed is ... -
