Two years field experiments were conducted at the Indian Institute of Rice Research Farm, Hyderabad, to compare the performance of field fortified poultry manure applications on some of the microbiological properties of soil. Continuous application of MEC treatments resulted in decline in the pH of the soil in all the treatments from the initial levels of 8.07. Analysis of post harvest soils of MEC for physical parameters revealed that plots treated with inorganic fertilizer alone had an adverse effect on soil dehydrogenase activities, soil phosphatase activites and soil microbial carbon. Soil microbial biomass C μg C/g soil dry wt was recorded in all the MEC plots compared to control and RDF. Soil enzyme observations such as Alkaline phosphatase μg p-nitrophenol/g soil/ha assayed in all the MEC plots were highly skewed. Lowest value of dehdrogenase μg TPF/g soil/24h activity was observed in the RDF plots. Higher values of soil dehdrogenase activities were recorded in all the MEC plots compared to control and fertilized plots.Keywords

Two years field experiments were conducted at the Indian Institute of Rice Research Farm, Hyderabad, to compare the performance of field fortified poultry manure applications on physical dynamics of soil. Continuous application of MEC treatments resulted in decline in the pH of the soil in all the treatments from the initial levels of 8.07. Analysis of post harvest soils of MEC for physical parameters revealed that plots treated with inorganic fertilizer alone had an adverse effect on bulk density, porosity, water holding capacity, void ratio and available water after harvest of crop. The values of bulk density ranged from 1.2 to 1.35 g/cc with a mean value of 1.3g/cc. Similar trends were noticed in terms of water holding capacity and percentage porosity values. The lowest bulk density (1.17g/cc) was observed in case of control plots whereas maximum (1.35 g/cc) was observed in case of NPK treated plots.Keywords

Pre experimental one group pre test- post design was conducted to assess the effectiveness of structured teaching programme on first aid management of Minor abrasions among elementary school children at Tirupati. Cluster random sampling technique each school was considered as a cluster and 50 children were selected by simple random sampling technique and assessed their knowledge by using structured questionnaire. Structured teaching programme on first aid management of minor abrasions were conducted. After seven days of the structured teaching programme the post-test were conducted by using the same pre-test questionnaire. Out of 50 children 18% (9) had inadequate knowledge, 80% (40) had moderately adequate knowledge and 2% (1) had adequate knowledge in pre test. 2% (1) had inadequate knowledge, 34% (17) had moderately adequate knowledge, and 64% (32) had adequate knowledge in post test. There was a significant improvement in knowledge and knowledge on practices related to prevention of minor abrasions at 0.01 levels. There is no significant difference between demographic variables of pre test and post test scores of knowledge and knowledge on practices.- Physiological and Molecular Characterization of Three Rice Genotypes with Differential Nitrogen Use Efficiency

Identification and adaptation of rice genotypes with high nitrogen use efficiency (NUE) is a potential approach in optimizing N
requirements, lowering the cost of cultivation and reducing the environmental pollution through the reduction of nitrous oxide
emission in rice. Three rice genotypes differing in their NUE were grown in hydroponics and field conditions and characterized for
physiological, yield parameters and NUE indicators along with expression analysis under low and recommended nitrogen conditions.
Significant variations were observed in 18 physiological, yield parameters and 8 NUE indicators among genotypes confirming the
genotypic variability for the traits under low nitrogen conditions. Reduction of yield related parameters except thousand grain
weight were noted. Correlation analysis of various yield components explains the significance of total biomass for grain yield,
straw yield, N content in grain, straw and nitrogen absorption efficiency. Differential expression of OsNIA2 gene in NUE efficient
genotypes viz., in shoots of GQ25 and ischolar_mains of IR55178 in the present study suggests its possible role in N metabolism and is
encouraging for exploring the possibilities of improving nitrogen use efficiency in rice.
