Weed management in isabgul (Plantago ovata Forsk)

Abstract

A field experiment was conducted during 2013-14 to 2015-16 at Seed
Spice Research Station, S.D. Agricultural University, Jagudan on
“Integrated weed management in isabgol ( Plantago ovata Forsk )”. The
soil was loamy sand in texture, neutral in soil reaction, with low in organic
carbon, medium in available phosphorus and potash. There were ten
treatments consisting physical and chemical weed control as well as their
integration. Weed control treatments affected considerably on growth and
yield attributes of isabgol. Whereas, there was no positive impact on test
weight. The maximum and minimum values of all the growth and yield
attributes were achieved under treatment when crop was facilitate with two
inter-culturing fb hand weeding at 25 and 40 DAS and unweeded control
treatments, respectively. Similarly, Physical method of weed control i.e.
Two inter-culturing fb hand weeding at 25 and 40 DAS recorded
significantly higher seed yield over rest of the treatments. The weeds were
controlled efficiently resulted in higher seed yield under physical method.
Effective removal of weeds throughout the crop growth period better space
and resources utilization i.e., moisture, nutrients, solar radiation etc. The
adoption of a purely physical method of weed control i.e. treatment T : two9
inter-culturing fb hand weeding at 25 and 40 DAS recorded significantly
lower sedges, monocot, dicot and total weed count and dry weight of
weeds during investigation. Thus, performing two inter-culturing followed
by hand weedings at 20 and 40 DAS produced sustainable and quality
seed yield and maintained the soil health.
