  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.
