Comparative effect of organic and inorganic fertilizer on the growth and yield of maize variety Hicorn-984 was studied at agronomic research area of University of Agriculture, Faisalabad during the year 2005. The trial was laid out according to randomised complete block design in triplicate and plot size was 3 m × 6 m. There were six treatments comprising of various levels of organic and inorganic fertilizer in different combinations and a control. Combined application of organic and inorganic fertilizer differed significantly from control as well as from their sole application. Comparison of treatments showed that inorganic fertilizer application at the rate of 70-50-35 kg NPK/ha along with 5 t/hapoultry manure showed maximum plant growth parameters such as leaf area (1537 cm2), plant height (195 cm), number of grains per cob (452) and thousand grain weight (234 g) which were at par with T5(70-50-35 kg NPK/ha along with 8 t/ha FYM) but significantly higher than the treatments where organic manures and inorganic fertilizers were applied separately. Maximum grain yield (5.7 t/ha) and cost-benefit ratio (1.7) were achieved in the treatment T6(NPK at 70-50-35 kg/ha along with 5 t/ha poultry manure) while, minimum grain yield (2.3 t/ha) and cost benefit ratios (1.1) were recorded in control. Combined application of organic and inorganic fertilizer results in increase in yield and profitability to farmer as compared to their sole application.

Field experiments were conducted at two locations in order to formulate phosphorus and potassium fertilizer recommendations of groundnut (Arachis hypogea) based on Mitscherlich-Bray equation. The treatments comprised four levels of phosphorus (0, 30, 60, and 90 kg phosphorus pentoxide (P2O5) ha-1) and three levels of potassium (0, 30, and 60 kg potassium oxide (K2O) ha-1) in all possible combinations. Theoretical maximum yield of groundnut was calculated by plotting log y (pod yield) versus 1/x (amount of nutrients applied). Fertilizer recommendation for various soil fertility levels and yield target were developed, and their validities were tested by conducting two field verification trials on the same soil. The results showed that although general recommended fertilizer dose resulted in highest yield of groundnut at both the locations, but value cost ratio and rate of increase in income were lowest with this fertilizer treatment, and 90% of maximum yield treatment was superior in terms of economics of fertilizer and risk factor.

Field experiments were conducted at two different locations (Barani Agriculture Research Institute Chakwal and farmer's field in Talagang) in northern rainfed Punjab, Pakistan, to assess relative efficiency of two sources of sulfur (S) in enhancing nitrogen (N) fixation and yield of chickpea (Cicer arietinum L.). The treatments were four combinations of two levels of S (15 and 30 kg ha -1) from two sources [gypsum and ammonium sulfate (AS)] and a no-S control. Application of S significantly increased seed yield up to 12% and 14% at Chakwal and Talagang, respectively. Response (kg seed yield kg -1 S) at economic optimum dose (EOD) was greater for AS than for gypsum. Sulfur application enhanced the S uptake at both locations significantly. Sulfur harvest index and S economic yield efficiency ratio were greater at Talagang than at Chakwal. Sulfur application resulted increases in N uptake by 19% and 20% and N fixation by up to 19% and 30% at Chakwal and Talagang, respectively. Ammonium sulfate was more effective in increasing N fixation and uptake as compared to gypsum at Chakwal, whereas the difference between the two sources was nonsignificant at Talagang. Thus, it can be concluded that S should be applied to chickpea crop to enhance yield and improve soil fertility status as result of greater amount of N fixed. © 2012 Copyright Taylor and Francis Group, LLC.

A field experiment was conducted at Barani Agriculture Research Institute Chakwal Punjab, Pakistan to assess the seed yield, nitrogen fixation and nutrient uptake by chickpea (Cicer arietinum L.) in response to application of different levels of phosphorus (P) and sulfur (S). The treatments comprised three levels (0, 40 & 80 kg P 2O 5 ha -1) of P and three levels (0, 15 & 30 kg S ha -1) of S from two sulfur S sources (gypsum & ammonium sulfate) in different combinations. The trial was laid out according to randomized complete block design with split split plot arrangement. Application of P and S resulted in significant increase in seed yield by 21 and 12% over control, respectively. Effect of combined application of P and S was synergistic at nutrient application rate of P 40S 15, while antagonistic at P 80S 30. Sulfur application had significant effect on percent nitrogen derived from atmosphere (% N dfa), while effect of P was non-significant. There was significant increase in protein content of chickpea seed due to application of S. Application of both P and S resulted in increase in nitrogen (N) fixation by 16%. Value cost ratio was less than 2 for higher level of P either sole or in combination with S. A fertilizer combination of P 40S 30 is more economical and cost effective for chickpea production under rainfed conditions. © 2011 Friends Science Publishers.

Seed yield and nitrogen fixation of legumes can be enhanced by supply of adequate amount of nutrients and inoculation. A field experiment was carried out at the Research Farm of Arid Agriculture University Rawalpindi (Pakistan) during summer 2009 using soybean (Glycine max) as test crop. The objective of this study was to investigate the effect of inoculation in combination with different sulfur rates (0, 15 & 30 kg S ha -1) on soybean growth, nitrogen fixation and soil nitrogen balance. Experiment was laid according to randomized complete block design in triplicate. Combined application of inoculation and sulfur (30 kg ha -1) resulted in significant increase in seed yield and yield attribute relative to control. Soybean plant height, number of pods per plant, straw yield, seed yield and dry matter yield increased up to 14, 56, 25, 20 and 26% as compared to control, respectively. Nitrogen uptake and fixation increased from 180 to 271 and from 83 to 143 kg ha -1 in the treatment of inoculation +30 kg S ha -1. Soil nitrogen balance after harvest of soybean crop was negative in all the treatments and this deficit increased with increase in dry matter yield. © 2011 Friends Science Publishers.

A two year field study was conducted at two different locations in northern rainfed Punjab, Pakistan to assess the effect of different rates of sulfur application from various sources on soil sulfur fractions and growth of Brassica napus. The treatments included three sulfur sources i. e., single super phosphate, ammonium sulfate and gypsum each applied at five different rates (0, 10, 20, 30 and 40 kg S ha -1). Sulfur application had a significant positive effect on the growth and yield parameters of Brassica napus. Among the sulfur sources ammonium sulfate resulted in maximum increase in plant growth and yield parameters, followed by single super phosphate. Sulfur content and uptake by crop plants was significantly higher with ammonium sulfate application as compared to other two sulfur sources. Sulfur application also exerted a significant positive effect on different S fractions in the soils. On an average, 18.0% of the applied sulfur got incorporated into CaCl 2- extractable sulfur fraction, while 15.6% and 35.5% entered into adsorbed and organic sulfur fractions in the soils, respectively. The value cost ratio increased significantly by sulfur application up to 30 kg ha -1. Among sulfur sources, ammonium sulfate performed best giving the highest net return.

Nitrogen fixing capacity of leguminous plants can be increased by the supply of adequate amounts of nutrients, especially phosphorus and sulfur. Some nutrients have direct involvement in the process of nitrogen fixation while others affect by improving growth of host plant. Field experiments were conducted at two different locations in northern rainfed Punjab, Pakistan, to assess the amount of nitrogen fixation and nitrogen uptake by chickpea (Cicer arietinum L.) during crop growing seasons 2006-2007 and 2007-2008. Treatments were: phosphorus levels (0, 40 and 80 kg P 2O 5 ha -1); sulfur sources (gypsum and ammonium sulfate) and levels (0, 15 and 30 kg S ha -1). The experimental design was randomized complete block with split-split plot arrangement: phosphorus levels in main plots, sulfur sources in sub-plots and sulfur levels in sub-sub-plots. Phosphorus (80 kg P 2O 5 ha -1) increased nitrogen fixed and uptake by 33 and 31 % over control. However, effect of phosphorus on nitrogen derived from atmosphere was not significant while that of sulfur was significant. Sulfur (30 kg S ha -1) increased nitrogen derived from atmosphere, amount of nitrogen fixed and nitrogen uptake by 6, 25 and 17 % over control. Ammonium sulfate treatments caused significantly higher amount of nitrogen fixed and higher nitrogen uptake as compared to gypsum treatments, although both sulfur sources were similar regarding percent nitrogen derived from atmosphere. A strong positive correlation (R= 0.98**) between amount of nitrogen fixed and nitrogen uptake at both locations was observed. There was a direct effect of sulfur on the process of nitrogen fixation, whereas phosphorus mainly affected growth of chickpea.

Field experiments were conducted at two different locations under rainfed conditions of Punjab, Pakistan to assess nodulation, nitrogen fixation and nutrient uptake by chickpea (Cicer arietinum L.) in response to application of three rates [0, 40, and 80 kg phosphorus pentoxide (P2O5 ha-1)] of phosphorus and three rates (0, 15 and 30 kg S ha-1) of sulfur in different combinations. Effect of phosphorus application was nonsignificant while that of sulfur was significant on percent nitrogen derived from atmosphere. Both phosphorus and sulfur application resulted in increase in nitrogen fixation up to 38% and 33% over control, respectively. Nutrient uptake [nitrogen (N), phosphorus (P), and sulfur (S)] increased significantly with the application of phosphorus and sulfur and correlated positively with nitrogen fixation. There is direct involvement of sulfur in the process of nitrogen fixation whereas effect of phosphorus on nitrogen fixation is indirect mainly through enhanced growth and dry matter production. © 2013 Copyright Taylor and Francis Group, LLC.

Balanced fertilizer use is the key to get maximum crop yield. It is very important to work out optimum level of each nutrient application since there may be positive (synergistic) or negative (antagonistic) interaction between them. A field experiment was conducted at Barani Agriculture Research Institute Chakwal, Pakistan for two years to assess the seed yield, agronomic efficiency and nutrient recovery by chickpea (Cicer arietinum L.). The treatments comprised three levels (0, 40 and 80 kg P2O5 ha-1) of phosphorus and three levels (0, 15 and 30 kg S ha-1) of sulphur from two sulphur sources (gypsum and ammonium sulphate) in different combinations. The trial was laid out according to randomised complete block design with split-split plot arrangement. Application of phosphorus and sulphur resulted in significant increase in seed yield by 29 and 12% over control, respectively. The economic optimum dose of phosphorus and sulphur, as calculated from quadratic response equations ranged from 56 to 58 and 32 to 53 kg ha-1 respectively. Effect of combined application of phosphorus and sulphur was synergistic at both nutrient application rates of P40S15 and P80S30. Agronomic efficiency and sulphur recovery were higher due to combined application of phosphorus and sulphur as compared to individual ones. Phosphorus recovery was higher at lower level of phosphorus (40 kg P2O5 ha-1) as compared to higher level (80 kg P2O5 ha-1). Value cost ratio was less than 2 for sole application of higher level of phosphorus. A fertilizer combination of P80S30 was more economical and cost effective.

Field experiments were conducted at two different locations (Barani Agricultural Research Institute Chakwal and farm field Talagang, district Chakwal) for two crop-growing seasons in northern rainfed Punjab, Pakistan to assess the yield and micronutrient uptake of chickpea (Cicer arietinum). The treatments were four combinations of two levels of sulfur (15 and 30 kg/ha) from two sources (gypsum and ammonium sulfate) and a no-sulfur control. Application of sulfur resulted in a significant increase in seed yield up to 17% over control. Ammonium sulfate was a more efficient source of sulfur as compared to gypsum at both the locations. Sulfur application resulted in a significant increase in micronutrient uptake by plant; however effect of sulfur application on soil pH at the end of experiment was not significant. Availability of soil zinc and copper increased with sulfur application at the end of two year experiment. Tissue copper and iron and soil available copper and iron correlated negatively with soil pH. Sulfur should be applied to chickpea grown under rainfed conditions in order to increase seed yield, to improve nutritional composition of product and to enhance efficiency of other fertilizers.
