Author(s): C Sudha Rani and C Sudhakar
Abstract: A field experiment was at Agricultural Research Station, Tandur, Professor Jayashankar Telangana state Agricultural University for three consecutive Kharif seasons 2014-15 and 2015-16 2016-17 to assess the Effect of plant growth retardants on growth, yield and economics of Kharif Pigeonpea. Results indicated significant difference between the treatments over control, but there is non-significant difference among the treatments which received foliar sprays of growth retardants with regard to growth parameters like plant height, Primary branches and secondary branches. The treatment which received foliar spray of Mepiquat chloride 2000ppm recorded significantly higher yield of 1940 kg/ha with 69.4 percent of pod retention. Maximum harvest index 23.9 was registered with foliar spray of Mepiquat chloride 2000ppm, Benefit cost ratio ranged from 2to 3.8. Maximum benefit cost ratio was recorded by T5 (3.8) but it is on par with T4. Increase in seed yield of T5 was to the tune of 74% and 66% in T4 more over control.
