Influence of different organic manures and fertility levels on growth and quality aspects of okra [Abelmoschus esculentus (L.) Moench] under semi-arid conditions

Abstract

A field experiment was conducted during kharif season at Jobner, Rajasthan to study the influence
of different organic manures and fertility levels on growth and quality attributes of okra viz.
[Abelmoschus esculentus (L.) Moench] with 16 treatment combinations of organic manures (control,
FYM @ 15 t/ha, vermicompost @ 5 t/ha, poultry manure @ 5 t/ha and 4 fertility levels viz. (control,
50% RDF, 75% RDF and 100% RDF. Results revealed that application of poultry manure @ 5 t/ha,
significantly showed higher plant height, number of branches per plant, leaf area, chlorophyll content
in leaves and also increased levels of NPK and protein content in fruits as compared to control,
FYM @ 15 t/ha and remained at par with vermicompost @ 5 t/ha, while the application of 75 % RDF
was significantly at par with 100 % RDF and showed enhanced growth and quality over rest of the
levels. However, crude fibre content remained materially unchanged under different organic manures
and fertility levels.
