Effect of Panchagavya as Organic Input on Growth, Yield and Economics of Late Sown Rapeseed

Abstract

A field experiment was conducted in ICR farm of Assam Agricultural University, Jorhat to evaluate the effect panchagavya on growth, yield and economics late sown rapeseed in Assam condition during rabi season, 2020-21. The experiment was laid out in Randomised Block Design with three replications and eight treatments like T1: control, T2: RDN through vermicompost (VC), T3: Vedic panchagavya soil application (3%), T4: 1 tonne VC/ha as basal + vedic panchagavya foliar application (3%), T5: enriched panchagavya soil application(3%), T6: enriched panchagavya foliar application(3%), T7: vedic panchagavya basal application (1.5%) + vedic panchagavya foliar application (1.5%), T8: enriched panchagavya basal application(1.5%) + enriched panchagavya foliar application(1.5%). Results showed that T4 was found to be best among all the treatments regarding growth, yield characteristics, and yield of the late sown rapeseed. The highest values of the growth metrics as well as yield metrics were recorded under treatment T4. This treatment produced the highest seed yield (6.89 q/ha) and stover yield (20.48 q/ha). Likewise, the highest oil yield (258.91 kg/ha) of rapeseed and highest gross return (Rs. 55120/ha) was observed in T4 treatment. But, the maximum net return (Rs. 34020/ha) and B:C ratio (1.90) were recorded under treatment T5.
