Fertilizer use efficiency of nitrogen is very low due to various types of losses. This two year field experiment was carried out to investigate the effect of various levels of nitrogen and its application methods on phenology, growth indices and quality of wheat. Fertilizer application methods (broadcast and side-dressing) were placed in the main plots, while nitrogen levels (60, 90, 120, 150, 180 and 210 kg/ha) applied in sub plots. Crop data showed that nitrogen methods had non-significant effect on phenology, physiology and quality parameters. Fertilizer application rates rendered significant effect on various parameters except days to emergence. Nitrogen at 210 kg/ha gave significant increase in the phenological and growth parameters. Leaf area index and leaf area duration were significantly affected by the rate of nitrogen fertilizers. Protein contents were also increased by the application of higher amount of nitrogen. Interaction among application methods and nitrogen levels showed significant variations in net assimilation rate, while crop growth rate remained significant in the second year and protein content had shown significant variation during the first year of study. |

Beta carotene is a precursor of Vitamin A and is abundantly found
in different vegetables and possess significant anti-oxidant potential. In the
present study an attempt was made to determine the concentration of β-carotene
from different vegetables sources viz carrots, corn, paprika and pumpkin. After
the extraction its concentration was quantified by using spectrophotometer and
the data was statistically analyzed. The results expressed that corn had highest
amount of β-carotene (31%) followed by paprika (25%) then carrots (24%)
and pumpkin (20%). This study provides a base line for extraction of costly
β-carotene from local vegetable that can overcome the problem for the import
β-carotene. Other findings revealed significant potential of this compound
from indigenous sources and also found cheaper than the synthetic sources. |
