Effect of herbal extracts on growth, physiological parameters, yield and yield attributes of Indian mustard

Abstract

A field experiment was conducted during winter season of 2016-17 at ICAR-Directorate of Rapeseed and Mustard
Research, Bharatpur, Rajasthan to evaluate the effect of herbal extracts on growth, physiological parameters, yield and
yield attributes of Indian mustard (Brassica juncea L.). The experiment was laid out in randomized block design with four
treatments and five replications, viz. herbal extracts, RDF + one irrigation, RDF + KNO3 spray and Control. Results
revealed that maximum plant height (231.2 cm), plant leaves (49.6), Leaf area index (5.9), chlorophyll content (50.8),
primary (7.3) and secondary branches (20.6) had with T2 treatment receiving RDF + one irrigation. The yield and yield
attributes; length of silique (5.1 cm), number of seeds/siliqua (17.0), and test weight (5.2 g) were highest under the
treatment of RDF+one irrigation as compared to other treatments. This study indicated that application of recommended
dose of fertilizers with one irrigation at 65 days after sowing was found more beneficial in terms of getting higher yield
and plant growth in climatic conditions of Rajasthan.
