Effect of different phosphorus and sulfur levels on nitrogen fixation and uptake by chickpea (Cicer arietinum L.)
Provedor de dados: 115
Autores: Islam,Muhammad; Mohsan,Saleem; Ali,Safdar.
Nitrogen fxing 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 afect 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 P2O5 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...

Effect of integrated application of sulphur and phosphorus on nitrogen fixation and nutrient uptake by Chickpea (Cicer arietinum L.)
Provedor de dados: 115
Autores: Islam,Muhammad; Safdar,Ali.
Nitrogen fixing capability of legumes can be enhanced by the supply of adequate amounts of nutrients, especially phosphorus (P) and sulphur (S). However, combined application of P and S may have synefgistic oí antognistic effects on crop yield, depending upon initial fertility status of soil, level of nutrients applied and test crop used. Field experiments were conducted at two different locations (Barani Agriculture Research Institute, Chakwal, and farmer's field, Talagang) in northern fainfed Punjab, Pakistan, to assess nodulation, nitrogen fixation and nutrient uptake by chickpea (Cicer arietinum L.) in response to application of P (0, 40 and 80 kg ha-1) and of S (0, 15 and 30 kg ha-1) in different combinations. Application of P and S significantly...
