| Abstract | ||||
| Two field experiments were carried out during 2013/2014 and 2014/2015 seasons to study the effect of organic fertilization (farmyard manure “FYM” at the rate of 20 t/fed and humic acid “HA” at the rate of 20 kg/fed), NPK fertilization (50 % of the recommended doses i.e. 40 kg N + 20 kg P2O5 + 40 K2O/fed and 100 % of the recommended doses i.e. 80 kg N + 40 kg P2O5 + 80 K2O/fed) and foliar spraying with some biostimulants (without, foliar spraying with Stemo at rate of 0.5 ml/liter water, potassium salicylate at rate of 2.0 ml/liter water, Super-grow at rate of 1.5 ml/liter water and mixture of Stemo at rate of 0.25 ml/liter water + K. Sal at rate of 1.00 ml/liter water + Super-grow at rate of 0.75 ml/liter water) as well as their interaction on growth, yield and its components and chemical composition of pea Master B cultivar. The experiment was carried out in a strip-split plot design with three replications. The obtained results could be summarized as follows:- The maximum means of all studied characters were recorded by humic acid (HA) at the rate of 20 kg/fed, while the minimum values were resulted from using farmyard manure (FYM) at the rate of 20 t/fed in both seasons. - Increasing NPK fertilization levels from 50 % of the recommended doses (40 kg N + 20 kg P2O5 + 40 K2O/fed) to 100 % (80 kg N + 40 kg P2O5 + 80 K2O/fed) was accompanied with significant increase in all studied characters. - Foliar spraying with mixture exceeded the other treatments with some biostimulants and resulted in the highest means of all studied parameters in both seasons. It could be recommended that organic fertilizing pea plants with humic acid at the rate of 20 kg/fed and mineral fertilizing with 80 kg N + 40 kg P2O5 + 80 K2O/fed in addition to foliar spraying three times with the mixture of biostimulants i.e. Stemo at rate of 0.25 ml/liter water + K. Sal at rate of 1.00 ml/liter water + Super-grow at rate of 0.75 ml/liter water in order to maximizing pea growth, yield and quality. | ||||
