Abstract
Two field experimenls were carried out at Dekerniss distract. Dakahlia Governorate. Egypt during the two successive winter seasons of 2000/2001 and 2001/2002 to evaluate the effeci of phosphorous fertilizer levels wilh or without phosphorien and some different growth promoters enner single or in combined applicalions on the vegetative growth, yield and its components of pea plant (Pisum sstivcm L.) c«. Master-B.
Split-split plot syslem in a rancorntzed block design with three replicates was used in bolh growing seasons. The foliar treatments (control, vitamin Bl, yeast extract and vitamin Bl + yeast extract) were randomly located in the main plot whereas the sub-plots were devoted for Ihe phosphorous fertilizer levels (100,150 and 200 kg calcium superphosphatelfed.) and Ihe biofertilizer treatments (with and without phosphorein) were assigned to the sub-sub plots.
The results of the following treatments (foliar application with vitamin BI + yeast extract, phosphorous at 200 Icg/fed. calcium superphosphate and biofertilizing with phosphorein as a single factors) showed a significant increase in growth vegetative parameters, chemical content of leaves, also they reduced the number of days to the first nower. For this reason they tended to increase both tolal fresh and dry yield.
The interaction between (vitamin 6, + yeast extract) 'combined with (200 kg/fed. calcium superphosphate) caused a Significant increase in both totat fresh and dry yield. Also, the combination between (vitamin 8, .;. yeast extract) combined with biofertilizer gave 5i milar results as previous ones.
Using foliar applications of yeast extract + vitamin B, at 200 kg/fed. calcium superphosphate plus phosphorien, caused a marked increase in pea yield and its components as compared with control (200 kgtred. calcium superphosphate).
It was noticed that using foliar application of yeast extract at 100 kg/ted. calcium superphosphate in combination with seed inoculation with phosphorien gave yield as high as 200 kglfed catcium superphosphate alone and consequently decreased the environmental pollution.
