“…The differential response at different applied rates of S in these studies may be due to difference in initial soil S levels, soil texture, and climatic conditions of experimental sites. The results of the present study are in conformity with previous work (Khan et al 2006), having almost similar soil-test values and climatic conditions. Seed-to-straw yield ratio was greater at Talagang as compared to Chakwal because of better climatic conditions at Talagang.…”

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.

“…He computed (from quadratic equation) 53 kg S ha −1 as the optimum level of S application for maize. Khan et al (2006) suggested 57.52 kg S ha −1 as the critical level for maximum yield of maize. Sharma et al (2007) worked out doses of 44.9 and 37.3 kg S ha −1 in the form of gypsum as EOD for wheat and rapeseed, respectively.…”

“…The lowest sterility percentage was recorded with boron application due to enhanced seed filling activity. Higher 1000 seed weight with sulphur application was in accordance with Khan et al (2003). Yield Seed yield: Application of RDF + ZnSO 4 @ 25 kg ha -1 (2.17t ha -1 ) resulted in the highest seed yield, which was on par with that of RDF+ Boron @ 1 kg ha -1 (2.12 t ha -1 ), while the lowest was recorded under only RDF application (Table 2).…”

Abstract:The field experiment was conducted at Department of Agronomy, College of Agriculture, OUAT, Bhubaneswar during summer 2014 to find out appropriate hybrids and nutrient management practices for summer sunflower. Application of recommended dose of Fertiliser(RDF) i.e. 60-80-60 kg N, P 2 O 5 -K 2 O ha -1 + ZnSO 4 @ 25 kg ha -1 recorded the maximum capitulum diameter (15.60cm), seed yield (2.17 t ha -1 ), stover yield (4.88 t ha -1 ) and oil yield (0.91 t ha -1 ), while application of RDF + Boron@ 1 kg ha -1 recorded the highest number of total seed (970) and filled seed per capitulum (890) with the lowest unfilled seed (80) and sterility percentage (9.0%). The hybrid 'Super-48' recorded the highest seed and oil yield of 2.17 and 0.91 t ha -1 , respectively, at recommended dose of fertiliser + ZnSO 4 @ 25 kg ha -1 . Experiment was conducted in evaluating the new hybrids in addition to evaluate the response of variety to different nutrient management practices.

“…Overall, Cl 2 -dominated irrigation affected maize plant growth more than SO 4 22 . The relatively less adverse effect of SO 4 22 salt on plant growth might be due to the fact that sulfur is as an essential plant nutrient (Khan et al 2006). Most of the crops are quite insensitive to high concentrations of SO 4 22 when grown in nutrient solutions (Eaton 1966).…”

Generation of different biowastes is increasing day by day, and ultimate load on agricultural lands has increased. Concerns over increased phosphorus (P) application with nitrogen (N)-based compost application shifted the trend to Pbased applications. But focus on only one or two nutritional elements will not serve the goals of sustainable agriculture. Full insight into nutrient availability from different composts is necessary. The need to understand the nutrient release and uptake from different composts has increased because of the use of saline irrigation water in the recent scenario of fresh water shortage. Therefore, current greenhouse studies were designed to evaluate the bioavailability and leachability of some micronutrients [calcium (Ca), magnesium (Mg), and zinc (Zn)] from different biocomposts under chloride (Cl 2 ) and sulfate (SO 4 22) saline environment. In the first pot experiment, soil was amended with livestock compost (AC), poultry compost (PC), and composted sludge (SC) at the rate of 200 kg P ha 21 equivalent bases. Pots were irrigated with artificial saline water of sodium chloride (NaCl) or sodium sulfate (Na 2 SO 4 ; 60 mmol c L 21 ), and leachates were collected for Ca and Mg analysis. As composts were applied on total P bases, which left varying amounts of nutrients in each treatment, it was observed that nutrient uptake and release differed greatly regardless of the total amount applied with each compost type. Amount of Ca applied with PC (3.9 g pot 21 ) was greater, but Ca concentration in leachate was greater under AC-amended treatments. Magnesium concentration also varied greatly under compost types. Among the saline irrigation, Ca and Mg concentration in leachate increased under both saline irrigations compared to nonsaline treatment, and SO 4 22 had relatively greater ionic strength to replace cations than Cl 2 . Calcium, Mg, and Zn uptake by maize stem and leaves were greater from SC-amended pots followed by PC, SC, and control. Irrespective of the salt types, Ca and Mg uptake reduced under both saline irrigations, whereas Zn uptake increased as compared to nonsaline treatment. Among the salt types, it was observed that plant growth and nutrient uptake was more influenced by Cl 2 than SO 4 22 saline irrigation. In the second experiment, soil was saturated with NaCl and NaSO 4 (75 mmol c L 21 ) and amended with AC. The trend of nutrient uptake under both salt types was similar to first experiment, and the results of AC amendments have been discussed. It can be inferred from the results that regardless of the total amount applied, nutrient uptake greatly varies under different composts and their availability depends upon the source rather than total amount applied. Analogously, sulfatedominated irrigation water can increase the leaching of Ca and Mg from root zone more than chloride.
