  The response of rice plants to ordinary urea and slow-release fertilizer were studied in pot experiments at the green house of Tsukuba International Agricultural Training Center, Japan, during 1995. The amount of N in the plants grown under Meister 10 was equivalent to those of basal application of urea. The amount of N in the plants was higher in the post treated with highest dose of ordinary urea (1.5 g N/pot) both as a basal and top dressing application. The brown rice yield of Meister 10 and ordinary urea under the same dose was almost equivalent (11.96 and 11.35 g/plant). The basal application of urea (1.5 g N/pot) increased the brown rice yield (14.723 g/plant), compared with split application under the same dose (11.823/plant). The correlation analysis showed positive relationship between nitrogen content (%) and chlorophyll content r = 0.969 and r = 0.960) at panicle initiation and heading stage.

  The study was aimed at evaluating the performance of five Basmati rice varieties tasted at the Agronomic Farm, Gomal University, Dera Ismail Khan, during 1997. Variety Basmati-385 out yielded rest of the varieties by yielding 3.98 t ha–1 of paddy with maximum normal kernels (77.82%) and lowest sterility (33.28%). It was followed by Basmati-370 on all the parameters studied. Varity C-6129 was highest in straw yield and 1000-seed weight. Variety Basmati-198 didn’t perform well having statistically the lowest score in most of the recorded characters. Amongst these varieties, the productivity and adoption of Basmati-super 385 was remarkable. Although it was also praiseworthy for physicochemical properties yet it was superceeded by Basmati-super on account of slight differences. On the basis of these results, Basmati-385 is recommended for promising yield and Basmati-super for the quality attributes.

  The effect of irrigation frequencies i.e. 0, 2, 4, 6 and 8 was studied at the Faculty of Agriculture, Gomal University, Dera Ismail Khan, during the year 1995. The parameters like plant height, head diameter, number of grains per head, 1000-grain weight and grain yield per hectare were significantly affected by irrigation levels and six irrigations were found optimum for obtaining good yield of sunflower. On the basis of research findings, six irrigation are recommended for sunflower crop to obtain maximum seed yield under irrigated conditions.

  This field experiment was undertaken on already green manured soil for comparing the efficiency of various organic manures used as alone and in combination, for wheat production. Organic matter sources/treatments used in the study were: Farm Yard Manure (FYM), Poultry Litter (PL), Press Mud (PM) and Sewage Sludge (SS). The amount of each organic amendments used singly was 20 t/ha, while their combinations had 10 t/ha for each of the two amendments making a total of 20 t/ha in a treatment. The experiment was conducted on wheat cv. Bhakkar 2002 as test crop for two consecutive growing seasons (year 2004-05 and 2005-06). Results revealed that Application of all types of organic materials (FYM, PL, PM and SS) and their combinations improved the growth and yield attributes of wheat significantly over control in both the years. The highest biological and grain yield was obtained with the application of PL alone followed by FYM+PL and PL+PM, with a significant difference among them. Economic analysis revealed that the value of Cost-Benefit Ratio (CBR) was highest with FYM+PL followed by PM+SS and PL+PM. The lowest CBR values were recorded under FYM alone and FYM+SS. This was mainly due to smaller yield increase and additional income with these treatments.

  A field study was conducted on pre-green manured soil for the comparison of different organic manures applied singly and combined, for the production of wheat cv. Bhakkar 2002. Organic amendments used in the experiment included Farmyard Manure (FYM), Poultry Litter (PL), Press Mud (PM) and Sewage Sludge (SS). Quantity of the organic manures used as alone was 20 t ha-1 and their combinations contained 10 t ha-1 for each of the two amendments making up 20 t ha-1. The study was undertaken for two consecutive wheat growing seasons. The results indicated that combined use of PL, SS and their integration with other organic materials raised N contents in soil, wheat grain and straw to the maximum. The highest P contents in soil, wheat grain and straw were found with SS followed by SS+PL and PL alone and the highest K contents were recorded with PL, PL+PM and PM alone. It was found that N, P and K contents in soil, wheat grain and straw were highly correlated with N, P and K contents in the organic amendments.

  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.
