The Effect On Variety Of Growth Response Of Mango (mangiferea Indila) At Vegitative Stage
[To Determine Stem Diameter]

Mango is an important cash crop greatly contributing for food security of fruit growers. However, information was critically lacking with respect to growth response of mango rootstock to varying compositions. Thus, an experiment was conducted during 2022 to evaluate the effect on variety of growth response of mango (Mangiferea Indila) at vegetative stage. Seeds of the mango were sown in full top soil (M1); top soil: sawdust: sand (3:2:1)(M2); top soil: FYM (Farmyard manure): sand (3:2:1) (M3); and top soil: FYM: sawdust: (3:2:1)(M4). 

Randomized complete block design in a factorial arrangement with three replications were used. Data on growth parameters were collected and analyzed using GenStat software. Results: The findings of the experiment revealed that mango cultivar had significantly affected most of the growth parameters except shoot number. Moreover, potting media affected most of the parameters except stem diameter, root number, and shoot number. Interaction effects of cultivar and growing media significantly affected all parameters except internodes length, shoot number and stem diameter. 

Accordingly, interactions of local mango and M3 media combination gave the highest for most of the parameters with the order of M3=M1=M4>M2 for germination percentage, M3=M1>M4=M2 for plant height, M3>M1>M2=M4 for leaf number, M3>M1>M4>M2 for leaf area, M3=M1>M2=M4 for stem diameter, M3=M1>M2>M4 for root number, M3>M2>M1=M4 for root length, M3>M1>M2=M4 for fresh weight, M3>M1=M2=M4 for dry weight and Vigorosity II of mango. 

Conclusion: considering better mango performance on growth response and establishment in the study area, mango growers should use Local mango cultivar with soil potting media combinations of top soil: FYM: sand in the ratio of 3:2:1 for improving productivity and food security.
