Effect of some fertilization treatments on growth, yield, fruit quality and nutritional status of banana grande naine cultivar

الملخص EN

This work was carried out at the sandy soil of El-Khatatba region, Minofia Governorate, Egypt, through the two successive seasons of 2016 and 2017 to study the effect of organic fertilization combined with chemical fertilizer in presence of bio fertilizer on growth, yield, quality and nutritional status of banana Grande Naine cultivar.

Mother plants were planted at 3×2 m apart in March 2015 and two suckers were selected per each hole and the others were removed.

The obtained results showed that, the highest values of pseudostem height, pseudostem circumference, leaf area and assimilation area per plants were scored by T₁ recommended dose of chemical fertilization (RD), followed in descending order by T₄ treatment (75% RD+21kg compost+5ml bio.

/plant) with non-significant differences between them in the two seasons.

The highest values of bunch length, fruits yield per fed.

, the thickest bunch, the heaviest bunch, the highest number of fingers/hand and the heaviest hand were scored by T₁ treatment, followed in descending order by T₄ treatment in the two seasons.

The highest values of finger length, finger diameter and finger weight as well as the richest fruit pulp total sugars % and T.

S.

S.

% were recorded by T₄, followed by T₇ (75% RD+45g humic+ 5ml bio.

/plant) in the two seasons.

The heaviest pulp weight was obtained by those received T₄ treatment, followed in descending order by T₇ treatments, whereas the highest pulp/peel ratio was registered by T₇ and T₄ treatments in the two seasons.

Banana plants received the full dose of chemical fertilization (100% RD) is being the most promising one for inducing the greatest leaf total carbohydrates, N, P and K percentage, followed in descending order by T₄ and T₇ treatments without significant difference between them in the two seasons.
