Growth and yield performance of late sown Toria (Brassica rapa subsp. Toria) under integrated nutrient management practices in Assam

Abstract

A field experiment was carried out to quantify the effect of integrated nutrient management practices on late sown Toria
during Rabi seasons of 2017-18 and 2018-19. The experiment was laid out in randomized block design with ten treatments
viz., 100% (40-35-15 kg N-P2O5-K2O/ha + 10 kg borax/ha) and 75% RDF along with a successive combination of
vermicompost (@ 2 t/ha), sulphur (20 kg/ha), zinc (4 kg/ha and biofertilizers (Azotobacter and Azospirillum). The result
revealed that application of 100% RDF + vermicompost @ 2 t/ha + 20 kg S/ha + 4 kg Zn/ha + seed treatment with
biofertilizer consortia significantly increased the plant growth parameters and yield attributing characters in both the
years as compared to other treatments. The same treatment also registered the highest seed yield (945 and 1025 kg/ha)
and stover yield (2237 and 2292 kg/ha) during 2017-18 and 2018-19, respectively. Where as in both years the highest oil
content was obtained in treatment having 75% RDF + vermicompost @ 2 t/ha + 20 kg S/ha + 4 kg Zn/ha + seed treatment
with biofertilizer consortia
