ABSTRACT
An investigation on nano nitrogen and nano zinc with different levels of nitrogen approaches on growth and yield of paddy was conducted during rabi and kharif seasons of 2020-21 and 2021-22 at Krishi Vigyana Kendra, Gangavathi, Koppal, Karnataka, India. The experiment was laid out in split-split plot design with three replications, which consisted of four levels of nitrogen in main plots, three levels of nano nitrogen in sub plots and two levels of nano zinc in sub-sub plots. The treatment with application of 125 per cent Recommended Dose of Nitrogen (RDN) has recorded significantly taller plants (97.11 and 96.54 cm), higher number of tillers hill-1 (19.65 and18.14) and total dry matter (70.06 and 64.54 g hill-1) at harvest stage of crop and the Soil Plant Analysis Development (SPAD) values (46.69 and 42.60) and Normalized Difference Vegetation Index (NDVI) values (0.85 and 0.82) at flowering stage of crop, Similarly, foliar spray of nitrogen @ 4000 ppm has recorded significantly higher plant height (95.44 and 91.33 cm), higher number of tillers hill-1 (17.75 and 16.01), total dry matter (66.84 and 62.31 g hill-1) SPAD values at flowering stage (44.89 and 41.29), NDVI values at flowering stage (0.81 and 0.74), grain yield (5623 & and 6840 kg ha-1) and straw yield (5352 and 6581 kg ha-1). Interaction effect showed non-significant effect with different combination treatments.
ABSTRACT
Audit of phototherapy aims to examine their efficacy and functioning. Twenty-four centres providing neonatal care were visited by a team of two persons. Data form were completed with information regarding age of phototherapy units, its buildup in relation to number of tubelights, type of light and irradiance provided. Total of 58 units examined had a wide variety in relation to their build. There were only 21 units (36.2%) in which all the lights were in working order. Only five of the units (8.6%) had the recommended special blue lights. Only 18 of the units (31%) provided an acceptable level of irradiance. Phototherapy demonstrates a dose response relationship. By not providing optimum irradiance, the efficacy is compromised. This prolongs hospital stay and treatment costs. Acceptable standards should be insisted upon in purchase and maintenance of medical equipments.
