  Cultivated lands in erosion prone agro-ecologies incessantly experience a substantial loss of productive soil and organic matter. Currently, the fertility-management and rainwater-conservation practices are given emphasis separately. This study appraised collectively both the water-conservation and fertility-management practices for the restoration of soil productivity in eroded farmlands. Field experiments were carried out on wheat (Triticum aestivum L.) and maize (Zea mays L.) in eight farmer fields. Four fields of Missa soil series (Typic Ustochrept) and four of Rajar soil series (Typic Ustorthent) were selected. Treatments in each field were: farmers' practice as control without soil-water conservation, and with farmers' rate of fertilizer (per hectare 40 kg N + 30 kg P2O5); improved fertilization (per hectare 100 kg N, 60 kg P2O5, 2 kg Zn, and 1 kg B) without soil-water-conservation practices; soil-water-conservation practices (deep plowing, bund improvement, ploughing across the contour) + farmers' rate of fertilizers; and soil-water conservation + improved fertilization. Crop grain yields were at the highest with soil-water conservation + improved fertilization (per hectare wheat 3.31 Mg and 1.65 Mg in 2004-2005 and 2005-2006; and maize 4.55 Mg and 4.19 Mg in 2005 and 2006, respectively). The lowest yields were recorded under farmers' practice for both crops. Similar was the response for water-use efficiency and plant uptake of nitrogen, phosphorus, zinc, and boron. Missa soil series was more responsive than was Rajar to integrated soil-management practices. Synergistic application of soil-water conservation and improved fertilization practices significantly improved the crop yields, nutrient uptake, and water-use efficiency.

  A field experiment was undertaken for evaluating the performance of three lentil genotypes with phosphorus (P) fertilization at four rates: 0, 40, 60, and 80 kg P2O5 ha-1 under rain-fed conditions. Genotypes of lentil were: Masoor-93, Markaz-2001, and NARC-02/2. Masoor-93 showed the highest seed yield, crop-growth rate, net assimilation rate, and seed protein contents among all the tested cultivars. P applied at the highest rate (80 kg ha-1) caused the best positive response with respect to physiological traits, growth attributes, and yield components. Furthermore, the application of P-fertilizer was found to be feasible in economic terms, as the net return, value-to-cost ratio, and relative increase in income were enhanced successively at higher phosphorus rates. It was concluded that for maximum potential yield of lentil, genotype Masoor-93 is the best suited under rain-fed conditions provided that its P nutrition is enhanced. The pronounced genetic variability in lentil-yield traits suggests that nutrient-efficient germplasm can be screened through breeding programmes to promote lentil production.

  The combined effect of different rates of fertilizer (N + P) and concentrations of a growth regulator commercial product on growth and yield of cotton was studied. There were two types of treatments viz. fertilizer rates (F) and Mixtalol concentrations (M) placed randomly in the field under split-splot design with four replications. Main-plot treatments were: Fo Control/no fertilizer), F1 (half rate of recommended N and P fertilizers viz. 575 and 28.8 kg ha-1, respectively) and F2 (full rate of recommended N and P fertilizers viz. 115 and 57.5 kg ha-1, respectively). The sub-plot treatments included: Mo (Control/no Mixtalol Spray), M1 (2 pm Mixtalol sprays thrice) and M2 (3 ppm Mixtalol spray thrice). Thus there were nine treatments combinations in total. Data on plant height and number of branches per plant showed significantly increased values of these two with the both doses of fertilizer as well as Mixtalol over Control. The difference between M1 and M2 was non significant for both parameters, while the F1 and F2 gave statistically similar values for number of branches and F2 was superior to F1 with respect to plant height. The best combination was F2 x M1 and the lowest values were found in Fo x Mo. As regards the number of bolls per plant and seed cotton yield, F2 gave statistically better results than did F1 and F2. among Mixtalol treatments M1 performed better than M2. the synergistic effect was best with F2 x M1 and it was lowest at Fo x Mo. Thus it was concluded that cotton gave the highest response to full rate of fertilizer (F2) along with lower concentration (2 ppm) sprays Mixtalol (M1) as the most suitable combination.

  Experimental trials were conducted at Integrated Pest Management Programme, National Agriculture Research Centre Islamabad, to evaluate the resistance of host plants (cereals) against Rhopalosiphum padi (L.). For evaluation of susceptibility, twenty varieties/-advanced lines of National Uniform Wheat Yield Trails (NUWYT) Normal (N) of year 2004-2005 were used. In seedling bulk tests varieties/advanced lines were grouped into three categories resistant, moderately resistant and susceptible. Data from seedling bulk tests showed that DN-47 and PR 87 lines of wheat were resistant to aphid as compared to the other varieties/-advanced lines. In antixenosis tests varieties/-advanced lines were grouped into three categories, least preferred, moderately preferred, highly preferred. Lines V-01180, DN-47 and PR-84 were least preferred, sixteen varieties/-advanced lines were moderately preferred and only one variety V-9021 was found to be highly preferred.

  Effect of Effective Microorganisms is seen on groundnut growth. EM is applied on two varieties (V1 =1 C G -2261 and V2 = 1CGV-86550) in three treatments. These three treatments are T1 = control, T2 = seed inoculation and T3 = seed inoculation with EM EM spray , Treatment 13 showed more growth than T2 and T1 because in T3, EM is applied in the form of seed inoculation as well as EM spray on ground. So, growth can be increased by the application of more EM concentration,

  Integrated use of plant nutrients aim at combined use of inorganic and organic sources of plant nutrients to improve efficiency of applied nutrients, reduce environmental hazards and improve crop productivity. A field experiment was conducted at the Research Farm of Soil Science and SWC, Arid Agriculture University, Rawalpindi, Pakistan. It was laid out according to RCBD in split-plots with three replications. The sub-plot size was 6 m x 4 m (24 m2). The wheat-maize cropping system was used to record data of two summer maize crops in under rainfed environment. There were nine treatments of integrated plant nutrient management practices. These included: control (without NPK fertilizer, FYM or biofertilizer); half of recommended NPK; full dose of recommended N-P2O5-K2O (120-90-60 kg/ha); FYM @ 20 t/ha, FYM on N requirement basis + make-up dose of P/K fertilizer; ½ NPK + FYM @ 10 t/ha; ½ NPK + Biopower; ½ FYM + Biopower and ½ NPK + ½ FYM + Biopower. The significant increase in various yield attributes due to IPNM produced highest biological and grain yield of 8579 kg/ha and 3128 kg/ha in 2005; while these were recorded 8475 kg/ha and 3119 kg/ha respectively in 2006. Integrated plant nutrient treatments especially with Biopower improved NPK uptake over sole mineral/organic fertilizers. The economic analysis revealed that wheat-maize cropping system was profitable with integrated use of mineral, organic and/or biofertilizer Biopower under rainfed condition.

  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.

  A field study was conducted to determine the effect of Zinc (Zn) application as well as interactive effect of organic and mineral fertilizer sources of nitrogen (N) on maize productivity and nutrient uptake during 2008 at NARC, Islamabad. Four combinations of N sources, viz. control; 100 % recommended dose of N from Chemical Fertilizer (CF); 75% N from CF + 25% N from Farm Yard Manure (FYM) and 50% N from CF + 50% N from FYM and three levels of Zn fertilizer, viz. 0, 4, 8 kg Zn/ha were applied. Maximum maize grain yield, viz., 5.18 t/ha was obtained with 75% + 25% (CF + FYM) and 4 kg Zn/ha. It was statistically at par with treatment having 50% + 50% (CF + FYM) and 4 kg Zn/ha as well as 75% + 25% and 8 kg Zn/ha. Zinc application also enhanced maize grain yield by 12% over treatment where no Zn was applied i.e. 4.08 t/ha. Highest N uptake, viz., 98.7 kg/ha was observed with 50% + 50% (CF + FYM) and 8 kg Zn/ha application. Similarly, maximum Zn uptake, viz., 250.7 g/ha was observed with 75% + 25 % (CF + FYM) and 4 kg Zn/ha application. The study revealed that substitution of 25 or 50% N with FYM + 4 kg Zn/ha performed better than 100% N fertilizer alone, with respect to leaf area index, grain and straw yield, soil organic matter content and nutrient uptake.

  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.
