Simple random sampling technique was done in this experiment A survey method through face-to-face interview by using semi structured questionnaire which was used to collect data from 51 vegetable growers. The findings of the study showed that the percentage of respondents considering facing problems at different levels constraints were 61% low, 35% medium and 4% high level. The constraints of the respondents on organic farming faced according to rank order were insufficient understanding on the principle of OVP, insufficient training, lack of organic pesticides, difficulties on soil management, lack of co-operation, insufficient labor supply, required perception, time requirement for management for better yield, lack of monitoring & evaluation, and unsatisfactory price. Age, ed...

The study also attempted to describe some selected characteristics of organic vegetables cultivation and explore the relationships with knowledge on organic vegetables cultivation. A survey method of face-to-face interview using semi structured questionnaire was used to collect data from organic vegetable growers in Samsung, Khon Kaen, and Northeast Thailand which was selected by using simple random sampling method. Data were collected by semi structured interview schedule from 51 randomly selected households. Data revealed that highest proportion (70.6%) of organic vegetables’ grower had relatively low knowledge while 29.4 % of them had medium knowledge and had 0% of high knowledge. Age, education, family size, farming experience, training receive and the communication of the vegetables grower had significant positive relationship with their knowledge on organic vegetables production while ar...

Most rice bran (80%) is used by the rice miller to feed pigs. The remaining 'grower's share' is split between use as a supplementary feed for scavenging poultry and for fish. The extent of, and constraints to, integration between livestock and fish in the current situation are discussed. Potential fish production through direct use of ricebran and from livestock wastes is modelled based on data from on-station and on-farm research. The impact of changing distribution and use of surplus rice paddy and rice bran in the village on livestock and fish production is then considered. Feeding management for scavenging poultry has an important effect on productivity of both poultry and, subsequently, the amount of wastes available for fish culture. Inorganic fertilisa...

A combination of betaine, biotin, and chromium has been developed to enhance nutrient utilization efficiency. Ideally, the addition of a combination of supplements to livestock feed could improve ruminal fermentation, digestibility and nutrient utilization, nitrogen and energy balance, and metabolism. Abstract The objective of this study was to evaluate the effects of supplementation with a feed additive containing a combination of betaine, biotin, and chromium (BBC) and concentrate-to-roughage ratio (C:R ratio) on nutrient digestibility, blood metabolites, ruminal fermentation, nitrogen balance, and energy utilization in Thai native beef cattle. Five Thai feedlot native beef bulls at one year old of age and 87.6 ± 15.7 kg of body weight were assigned in a (2 × 2) + 1 augmented factorial experiment according to a 5 × 5 ...

Smart farming amalgamates this in order to enhance productivity and cut the operation cost. Thus, in this paper, we propose a novel smart system based on poultry farming over EVAP systems by utilizing mobile and wireless sensor networks with a well–known sensor mote, Tmote Sky, towards a WCF web service interaction. This system assists mobile users/ administrators to observe, and especially control an environmental behavior including an additional alert feature when there is a sudden environmental change with configured thresholds. The paper describes instruments and components of the key design of the system. For performance evaluation, we also practically investigated transmitted power consumption characteristics of sensor nodes using CTP and Dissemination multi–hop routing protocols.
