Abstract
Fertilization is indispensable in maintaining chemical quality of soil, avoiding nutritional imbalance in trees and obtaining high quality consistent production with the least possible environmental effect.
Reduction of environmental impact can be accomplished with sustainable agricultural practices such as a soil handling, rational use of fertilizers and watering, use of high quality organic matter and commercial bioinoculants based on selected beneficial microorganisms which allow promotion of plant growth.
In this research, we evaluated the use of integrated nutrition handling in orchards of 8-year-old Lapins cherry (Prunus avium L.) established on clay loam soil, located in Requinoa Commune, VI region of Chile.
Two treatments were established (T1: conventional fertilization, T2: integrated nutrition), on a random block design with five repetitions.
The integrated nutrition treatment included reduction of chemical fertilization of NPK of 50% in relation to the conventional treatment that consisted of 60 kg/ha, 15 kg P2O5/ha based on Entec 26®, phosphoric acid, potassium nitrate distributed on applications in spring and post-harvest, in spite of application of 15 kg de C/ha as Liberex 85%® (50% of carboxylic acids, 30% of fulvic acids and 5% of organic acids) and 30 L/ha of commercial inoculant Soil Builder® (1*106 ufc/ml, carbonated basis, nutrients, ureases, phosphatases and plant hormones). Five months after the application of bioinoculant and organic matter, measurements were taken on the production of root dry matter and fruit quality parameters such as yield, soluble solids, pulp pressure, fruit dry matter and fruit size.
The results were analyzed by ANOVA. The integrated nutrition treatment was significantly (p<0.05) better in terms of root dry matter (15% increase), fruit dry matter (5% increase) and fruit yield (8% increase). There were not statistical treatment effects on soluble solids, pulp firmness and fruit size.
This study suggests that inoculation of microorganisms and organic matter contributes to benefit cherry trees, and improves rhizogenic effect, increasing and maintaining fruit quality parameters, establishing themselves as useful tools of integrated nutrition handling in order to accomplish sustainable cherry production and soil quality through time.
