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. |

Field experiment was conducted to evaluate difference among various
levels of Nitrogen (N) fertilizer, its application techniques and their interaction
on the growth, yield components and yield of wheat. Treatments of N fertilizer
application techniques, viz., broadcast and side-dressing were allocated to
main-plots and nitrogen levels, viz., 60, 90, 120, 150, 180 and 210 kg N/ha
were placed in sub-plots. This experiment was repeated for two years with the
same treatments. Results revealed that nitrogen application techniques had non-significant
impact on most of the crop parameters except count of fertile tillers. Various
rates of nitrogen showed significant influence on all the parameters under study
and showed significantly higher grain yield of wheat with successive increase
of dose up to 180 kg N/ha. Maximum plant height and biological yield were obtained
under the highest nitrogen level, viz., 210 kg N/ha. However, the highest count
of fertile tillers, spike length, number of grains, 1000-grain weight and harvest
index were recorded in the treatment receiving 180 kg N/ha. Interactions between
fertilizer application techniques and nitrogen levels were non-significant for
all the crop parameters studied in this experiment on wheat. |

To investigate the effect of different levels of potassium fertilizer with
and without use of Farmyard Manure (FYM) on growth, yield and nutrition of tomato
a study was carried out in year 2011 in pots. FYM was kept as main plots with
five treatments of potassium (0, 60, 90, 120 and 160 kg K2O/ha) replicated four
time. The results indicated that application of FYM and various K levels had
significant effect on the growth, yield and nutrient content of tomatoes. The
highest yield of tomatoes was (39.05 t/ha) observed in the pots receiving FYM
and 41.97 t/ha was found in the treatment receiving K @ 120 kg/ha. The growth
parameters including number of flowers per plant, number of fruits per plant
and fruit diameter were also found significantly different by the application
of FYM and K fertilizer. The mineral nutrition of tomato showed significant
effect of FYM and K levels on plant P and K. FYM and K levels also significantly
improved soil K content. It may be concluded that the Potassium applied @ 120
kg/ha along with the FYM was effective in improving the tomatoes attributes
as well soil K content. |
