ABSTRACT
The experiment was carried out to investigate the influence of PGR's (Herbozyme 2 ml/lit. and Paclobutrazol with soil application @ 750 mg/m. and foliar application with 100, 50, 25 ppm) and nutrient chemicals (19:19:19 @2%, 0:52:34 @ 2%, and 13:0:45 @ 3% NPK) on two groups of 34 years old Alphonso mango trees aim to increase fruit retention and yield. All the treatments were significantly influenced the yield and yield attributes. Paclobutrazol by soil application 750 mg/m (14, 5, 0.91, 0.56). Resulted in higher no. of fruits set per panicle followed by foliar application at 3% KNO3 (12.33, 40.92 and 0.57) over control (5.83, 1.20, 0.30 and 0.08) at peanut , marble, egg and harvest stage of growth. Paclobutrozol (PP333), the member of triazole which is growth retardant and anti gibberellins in action affects the plants growth and development. Regarding the yield in terms of number of fruits, soil application of paclobutrazol recorded significantly more number of fruits (249.33) followed by 2% 13:0:45(3%) NPK (234.6) and paclobutrazol 100ppm (226.5) over control (157.33).
Key words :
Alphonso mango, fruiting attributes, Mangifera indiaca, nutrient chemicals, paclobutrazol, physiological traits.
