Abstract

Two field experiments were carried out in 2002-2003 and 2003-2004
winter seasons to study the effect of some bostimulants (Rhizobacterein and
Phosphorein) and NPK fertilizer levels (0-0-0, 5-5-5 and 10-10-10 kg/fad.) on
plant growth, chemical composition and green pod yield and its components as
well as quality (physical pod characters and nutritive value of seeds) of pea cv
Master B.
The results showed that inoculation of pea seeds with rhizobacterein
increased plant growth (plant height, nurrther of both leaves and branches, fresh
and dry weight of leaves and branches as well as total dry weight, minerals
content of leaves (N, P and K as a concentration), yield and its components
(average of pod weight, weight of podslplant and total green pod yield/fad.), as
well as physical pod characters (dry weight of seeds/pod, pod length, pod
thickness, number of seeds/pod and 100-seeds weight) and nutritive value of
seeds (N, P and K content, protein and total carbohydrates).
Increasing level of NPK fertilizer from 5-5-5 to 10-10-10 kg NPK/fad.
produced the highest values of different stud!ecl characteristics of vegetative
growth, chemical composition, yield and its components as well as their quality.
Rhizobacterein within the lowest used level of NPK fertilizer (5-5-5 kg/fad.)
followed by phosphorein within the highest used level of NPK fertilizer (10-10-10
kg/fad.) resuLted the highest values of rnosl studied characters.
