plant nutrients on yield and quality of brinjal" was carried
out at the College of Horticulture, Kerala Agricultural
University, Vellanikkara during 1993-1997.
Results showed that yield attributes of brinjal like
number of fruits, volume of fruits, yield per plant and yield
per plot was maximum with highest level of poultry manure (155
Kg N ha-1)
The crop duration as well as the number of harvests were
significantly increased when poultry manure was applied at the
highest level (155 kg N ha-1).
Quality parameters like ascorbic acid and total soluble
solids were maximum with the highest level of poultry manure.
,
The starch content as well as reducing sugar content of fruits
were maximum with higher level of FYM and poultry manure while
all the organic treatments were at par with regard to total
sugars. Moisture content of fruits increased with increasing
levels of N.
The appearance, flavour, texture and taste of cooked
fruits were superior from treatment involving lower level of
poultry manure while the colour preference was for the fruits
from treatments having inorganic fertilizers alone at lower
level.
Maximum per cent of unmarketable fruits after five days
and seven days of storage was obtained from the plants
supplied with inorganic fertilizers alone and minimum in
plants given with organic manures alone.
Seed characters like number of seeds per fruit, weight of
seeds per fruit, seed yield per plant and germination per cent
of seeds were maximum in treatments having higher level of
poultry manure (155 kg N ha-1).
Shoot and fruit borer attack was reduced with the
application of FYM alone, while incidence of epilachna beetle
was reduced with the application of FYM or poultry manure
alone.
Physical as well as chemical properties of soil in terms
of bulk density, organic carbon, total N, available P and K
were improved with the continuous application of organic
manures alone.
Total uptake of N, P and K were maximum for the plants
applied with higher level of poultry manure.
Poultry manure at higher level showed average stability
with regard to almost all yield contributing characters.
Brinjal cultivation was found to be more remunerative
with the application of poultry manure at higher level (155 kg
N ha-1) .
