Abstract
Response of greengram and blackgram to method and levels of micronutrients
mixture application in soils of Cauvery Command Area was studied at College of
Agriculture, V.C. Farm, Mandya during Kharif 2017 and 2018. The experiments were
laid out in RCBD with fourteen treatments viz., control, RDF + FYM, foliar application
of MMF1 (Fe + Mn+ Zn + Cu + Mo) and MMF2 (MMF1+B) at 20 DAS, 40 DAS, 20
and 40 DAS and soil application of MMS1 (2 times of MMF2), MMS2 (2 times of
MMS1), MMS3 (MMS1 –B) and MMS4 (MMS2 –B). The results revealed that
application of FYM + RDF + MMF1 at 20 DAS and MMF2 at 40 DAS recorded
significantly higher yield in greengram (1054.55 kg ha-1) and blackgram (1591.52 kg ha-
1) compared to all other treatments except FYM + RDF + MMS2 and FYM + RDF +
MMF2 at 40 DAS treatments. The content of Fe (51.23 and 47.60 %), Mn (36.25 and
9.11 %), Zn (28.04 and 29.99 %), Cu (12.36 and 6.00 %) and B (22.99 and 18.64 %) in
seeds were increased due to application of FYM + RDF + MMF1 at 20 DAS + MMF2 at
40 DAS over FYM+RDF treatment in greengram and blackgram, respectively. The
nutritional factors like protein, antioxidants activity were increased, while antinutritional
factors decreased with the micronutrients mixture application. Soil available nutrients
were significantly higher with the soil application of micronutrients mixture + FYM +
RDF treatments compared to control and FYM + RDF. Higher benefit cost ratio (1.98
and 3.24) was observed with the application of MMF1 at 20 DAS + MMF2 at 40 DAS +
FYM + RDF in greengram and blackgram, respectively and was on par with MMF2
application at 40 DAS.
