Abstract

An experiment was conducted during kharif 2019-20 at Agriculture Research Station, Rajasthan to find out the impact of foliar application of gibberalic acid on growth, yield and economics of pigeon pea. The experiment was laid out in a Randomized Block Design with eleven treatments which were replicated thrice The results showed that treatment GA3 @ 75 ppm at flower initiation & pod initiation stages resulted maximum grain yield (1270 kg/ha) and proved significantly superior to control, Water spray at flower initiation (FI) and pod initiation stages (PI), GA3 @ 25 ppm at FI stage and GA3 @ 25 ppm at FI stage. Maximum net return (Rs. 36000/-) was obtained with the GA3 @ 50 ppm at FI & PI stages and Maximum B: C ratio (2.04) was obtained with GA3 @ 25 ppm at flower initiation & pod initiation stages.

Keywords

Pigeonpea, GA3, foliar application, Correlation and regression

Conclusion

Based on the finding of the investigation it may be concluded that for obtaining optimum grain yield of pigeonpea with treatment GA3 @ 75 ppm at flower initiation stage is the best management practice. Whereas, optimum net return can be achieved with the foliar application of GA3 @ 50 ppm at flower initiation & pod initiation stages.
