ABSTRACT

Brassinolide, a steroidal compound of plant origin and salicylic acid, a phenolic
compound have been found to increase yield in green gram. But, the physiological
and biochemical basis of yield improvement are yet to be ascertained. A field
experiment was conducted to understand the influence of brassinolide (0.10, 0.25
and 0.50 ppm) and salicylic acid (500, 1000 and 1500 ppm) on certain physiological
and biochemical aspects of green gram plant leading to higher yield in this crop.
Altogether,8 treatments were given as foliar spray including two types of control –
namely water spray and no spray. Foliar application of these plant growth regulators,
once at pre-flowering and second time at flowering stage of the crop significantly
increased chlorophyll-a, b and total chlorophyll content, Hill activity in the leaves of
green gram plant. Reducing, non-reducing sugar, starch and soluble protein content
in the leaves were also increased over control and water spray due to these treatments.
Brassinolide at 0.25 ppm and salicylic acid at 1000 ppm were found to be most
effective indicating optimum doses respectively and brassinolide seems to be superior
than salicylic acid to influence these physiological and biochemical yield parameters
