Cutting Management and Nitrogen application influences Fodder Quality and Productivity of Dual Purpose Oat (Avena sativa L.)
A field experiment was conducted during Rabi 2016-17 at Instructional Farm, Rajasthan College of Agriculture, Udaipur. The objectives were to find out proper cutting management and nitrogen level for fodder quality and productivity of dual purpose oat. The experiment comprising combinations of five cuttings and four nitrogen level. Thus, 20 treatments; all were evaluated in split-plot design of single cut and randomized block design of double cut with three replications keeping cutting management in main and nitrogen in sub plots. The results of experiment revealed that cutting management at first and second cutting gave significantly higher plant height, dry matter accumulation, number of tillers, leaf stem ratio, green and dry fodder yield and crude fibre at C3 treatment and C5 treatment, respectively. Application of 30 kg N ha-1 after first cutting recorded significantly higher plant height, dry matter accumulation, leaf stem ratio, green (23.5 t ha-1) and dry fodder yield (11.7 t ha-1), production efficiency and chlorophyll content. Total green (43.24 t ha-1) and dry fodder yield (12.58 t ha-1) were recorded maximum with the application of 30 kg N ha-1 which was at par with 20 kg N ha-1. The application of 30 kg N ha-1 after first cutting recorded maximum ash content and crude protein which was at par with application of 10 and 20 kg N ha-1 after first cutting. Crude fibre per cent was maximum in control that at par with 10 and 20 kg N ha-1.
Pruning impact on flowering in Tamarind clones under high density planting
High density planting of six different tamarind clones viz., FCRI-TAM-06, FCRI-TAM-09, PKM 1, FCRI-TAM-03, FCRI-TAM-04 and FCRI-TAM-08 with spacing of 6 x 6 m was planted at Precision Silvicultural Field, Forest College and Research Institute, Mettupalayam in the year 2018. Pruning operation was adopted for the quick initiation of flower buds which was standardized at the height of 4 ft. Results of pruning revealed that significant difference was observed for chlorophyll content, leaf nutrient viz., Nitrogen, phosphorus and potassium in different stages of fruit formation. Clone varied considerably in number of fruits and fruit yield per tree, in which FCRI-TAM-06 recorded maximum yield (4.78 kg/tree) and minimum fruit yield was recorded in FCRI-TAM-04 (0.05 kg/tree).
Friction Characteristic of Bearing Alloy Steel used in Tractor
The purpose on this research is to examine friction characteristics of bearing alloy steel with paraffin oil lubrication and nitrogen gas lubrication in the cylinder block on tractor. Bearing steel is a type of steel with high resistance to wear, relatively low cost, and superior mechanical properties. An experiment was done to analyze the friction characteristics without using a coating treatment. The friction tests were performed using a pin-on-disk tester. Friction tests were conducted with different loads of 2 to 10 N and sliding velocities of 0.06 to 0.34 m/s using bearing steel. The experiment was done with nitrogen lubrication and paraffin oil lubrication. Paraffin oil lubricant was used to prevent wear during process. Nitrogen is shown to be effective for reducing the friction coefficient of bearing steel materials that are in contact with each other and subjected to a load and velocity.
Characteristics of Thermal Insulator for Various Aluminum-cotton Layer in Greenhouse
Greenhouse is known as one of the media commonly used for the planting process with a room control system. In accordance with its work objectives, a greenhouse was formed to be able to produce a room whose environmental conditions can be controlled properly. The use of aluminum-cotton as a greenhouse cover material is expected to be an alternative to better maintain temperatures in the greenhouse and also more economical. Lately the improvement of cotton features in various fields and utilization has also begun to be done. In this study, variations in fabrication layers were made to determine the effects of layers and also the appropriate type of fabric used as thermal insulators. There were nine types of aluminum cotton fabric layers as the variation. As a testing tool, the heating simulator system was self-designed using wood and aluminum plates. The analysis conducted in this study was the temperature changes that occur in the control room after 5 and 10 minutes of testing. The results of analysis showed that variations in fabrication layers provided a significant effect on material weight, controlled room temperature after 5 minutes, and controlled room temperature after 10 minutes. The most suitable samples to be used as thermal insulators based on tests in this study were samples A and E, which showed that there was a significant increase in temperature after 5 and 10 minutes of processing: 5ºC and 6ºC for sample A, and 1.67ºC and 2ºC for samples E.
ISOLATION AND IDENTIFICATION OF BRUCELLA MELITENSIS IN SHEEP IN TAMILNADU
The present study was carried out to find out the cause for abortion in a sheep flock in Thanjavur district of Tamilnadu, India. Out of 100 sheep in the flock, 20 abortions were recorded by the farmer. Based on the report, Vaginal swabs from recently aborted sheep and sera samples were collected from all affected animals. All tested sera samples were found positive for brucellosis. Culture and isolation were done on nutrient agar and blood agar media. Primary characterization was carried out by catalase test, oxidase test and modified ZN staining technique. Two suspected cultures were subjected to molecular characterization using the B.melitensis specific primers (IS711) found to be positive for Brucella melitensis. Outbreak of Brucellosis has been confirmed. This is a primary report of Brucella melitensis outbreak in Cauvery delta region of Thanjavur district, Tamilnadu. Study shows the occurrence of Brucella melitensis in the area which is of major zoonotic concern.
