Correlation Analysis of Horticultural Traits of Apricot as Influenced by Phyto Bio-Stimulants

To feed the growing population, phyto bio-stimulants play a key role in enhancing fruit yield without compromising quality, especially in the temperate fruit industry.Sitofex (CPPU) and Elanta Super (NATCA) are two new-generation phyto bio-stimulants in the fruit industry.To evaluate its efficacy on apricot, as many as 11 treatments with three replications comprising two doses of CPPU(5 and 10 ppm) and NATCA (50 and 100 ppm) and a combination of their lower doses (5 + 50 ppm) at two different stages i.e. pink bud stage (PBS) and petal fall stage (PFS) were designed.Results inferred that 10 ppm CPPU at PFS increased the overall vegetative growth, yield, and yield-attributing factors.On the other hand, 50 ppm NATCA at PBS reduced increased quality attributes of apricot fruits as compared to untreated control.A very strong relationship (R 2 > 0.80) was observed among yield and annual shoot growth, leaf area, fruit set, fruit retention and fruit equatorial diameter.The regression analysis was also carried out between yield and yield attributing parameters to know the trend towards yield when phyto bio-stimulants were used.
