Abstract:
A field experiment was conducted on the concomitant effect of boron, molybdenum and nickel as basal physiological traits and nodulation of blackgram (
Vigna mungo L. Hepper) at Agricultural college farm, Bapatla during
rabi, 2017-18. It consisted of eight treatments of micronutrient application
viz., control (T
1), B (T
2), Mo (T
3), Ni (T
4), B+Mo
(T
5), B+Ni
(T
6), Mo+Ni
(T
7) and B+Mo+Ni (T
8) with randomized block design concept and replicated thrice. The results revealed that application of B, Mo and Ni individually and in combination increased the CGR and RGR. Increase in NAR was observed with T
3 and T
5 to T
8. Increase in internal CO
2 concentration and decrease in transpiration rate was obtained with all treatments T
2 to T
8, but stomatal conductance and photosynthetic rate responded positively with treatments T
5 to T
8. Nodule number and nodule weight plant
-1 found increased with B, Mo and combination treatments T
5 to T
8.
