Abstract:
The present investigations entitled “Effect of Fertigation on Granulation in Kinnow mandarin” was carried out in the Horticultural Garden, Bihar Agricultural University, Sabour, Bhagalpurduring the year 2016-2018. The experiment was laid down in Randomized Block Design with 5treatments and 4 replications. The study comprises of one experiment in which Kinnow trees underinvestigation were subjected to different level of fertigation, viz. T1- 120% of RDF as fertigation; T2- 100% of RDF as fertigation; T3- 80% of RDF as fertigation; T4- 60% of RDF as fertigation; T5- 100% of RDF as soil application and fruit samples were harvested monthly starting from the month September till December for analysis. The results revealed that the degree of granulation found maximum (1.75 %) in 60% RDF as fertigation (T4) which is at par with T3 and minimum degree in 120 % of RDF as fertigation. Enzymatic activity linked to granulation as like diastase activity was recorded highest (24.80 mol/min.) in 100% RDF as fertigation and lowest (16.81mol/min) in 60% RDF as fertigation and with advancement in fruit ripening diastase activity decreases. However, for the pectin esterase activity, there was non significant effect of the different ferigation treatments and its value decreases as fruit undergoes maturation.
