Abstract
Multiple cropping (i.e. intercropping or mixed cropping) plays an important role in agriculture because of the effective utilization
of resources, significantly enhancing crop productivity compared with that of monocultured crops. The study was planed to assess the
effect of various concentrations (00, 30, 60, 90 kg ha-1) of phosphorous on the biochemical composition of grains of Hordeum vulgare L.
(NDB-1050) in mixed cropping system with Chickpea. Phosphorous is an essential ingredient for plants to convert atmospheric N (N2) into
an ammonium (NH4) as a useable form. The available nitrogen content was found more in the year 2006 (131 kg ha-1) than year 2005 (105
kg ha-1). The results of available nitrogen content were showed that the mixed cropping system enhances N fixation process because
phosphorous also influences nodule development through its basic functions in plants as an energy source. Reducing, non reducing and
total sugar content of H. vulgare L. were influenced by changes in the phosphorous doses. Maximum protein (13.43 %) was obtained at
60 kg P2 O5 ha-1 during the year 2006. Lysine, tryptophan and methionine content were found maximum in year 2006, respectively. Total
mineral content of grains of plant (0.99 g 100g-1) was found maximum by the application of 60 kg P2 O5 ha-1. It is possible that there was
an increase in the soil N made available by the leguminous chickpea species, and this could be another reason why there was an increase
in Hordeum vulgare L. shoot mass per plant with intercropping with chickpea.
