The field investigation entitled "Effect of plant growth regulators on yield and economics of soybean (Glycine max (L.) Merrill)" was conducted at experimental farm, Department of Agronomy, College of Agriculture, VNMKV, Parbhani during kharif 2018-19. The experiment was laid out in a randomized block design with nine treatments and three replications with a view to find out the influence of different growth regulators applied at flowering and pod developing stage of soybean. From the result it was revealed that application of seaweed extract (20%) + organic plant extract (80%) at flowering and developing stage recorded higher seed yield kg ha -1 , straw yield kg ha -1 , harvest index% and monetary returns, it was at par with organic plant extract and brassinosteroides (0.01%) + organic plant extract.

A field experiment was conducted during kharif season of the year 2018-19 at farm, Department of Agronomy, College of Agriculture, VNMKV, Parbhani to study the effect of plant growth regulators and fertilizer spray on growth and yield of Niger [Guizotia abyssinica (L.f.) Cass]." The investigation was carried out in RBD design with three replication and ten foliar application of plant growth regulators and fertilizers such as T1-19:19:19 (1%), T2 -Urea (1%) + DAP (1%), T3 -DAP (2%), T4 -Urea(2%), T5 -Brassinosteroids (0.05%), T6 -NATCA (50ppm), T7 -NAA (20ppm), T8-GA3(20ppm), T9 -Nitrobenzene (400ppm), T10 -Control (no spray). The result of experiment revealed that among the treatments foliar application of Brassinosteroids (0.05%) (T5) to Niger at bud initiation stage recorded significantly higher growth, yield attributes and yield as compare to other treatments and which was at par with foliar application of NATCA(50PPM) and nitrobenzene(400PPM).
