Abstract: A field experiment was conducted at Agricultural College Farm, Bapatla during Kharif 2013 to study the effect of foliar application of potassium, boron and zinc on quality p and seed yield in soybean. The experiment was laid out in clay loam soil in a Randomized Block Design with eight treatments and three replications. Treatments consisted of T1- Foliar applications of potassium nitrate @ 2 per cent at 30 and 60 DAS, T2- Foliar application of boric acid @ 50 ppm, T3- Foliar application of zinc sulphate @ 1 per cent, T4- Foliar application of potassium nitrate @ 2 per cent + boric acid @ 50 ppm, T5- Foliar application of potassium nitrate @ 2 per cent + zinc sulphate @ 1 per cent at, T6- Foliar application of boric acid @ 50 ppm + zinc sulphate @ 1 per cent, T7- Foliar application of potassium nitrate @ 2 per cent + boric acid @ 50 ppm + zinc sulphate @ 1 per cent, T8- Control (Water spray). The results revealed that foliar application of potassium nitrate @ 2 % + boric acid @ 50 ppm + zinc sulphate @ 1 % (T7) at 30 and 60 DAS was found to be superior in increasing the quality parameters like SCMR (29.12% over control), total chlorophyll content (20.60% over control), protein (12.82% over control), oil content (26.24% over control) and yield (28.59% over control) followed by potassium nitrate @ 2 % + boric acid @ 50 ppm at 30 and 60 DAS (T4), boric acid @ 50 ppm + zinc sulphate @ 1 % at 30 and 60 DAS (T6) and potassium nitrate @ 2 % + zinc sulphate @ 1 % at 30 and 60 DAS (T5).
