The quality of potatoes for processing depends on varietal, environmental and crop management factors, and the consumption of potato products has increased.The objective of the research was to determine the effect of calcareous amendments on the production and frying quality of potatoes potato cv. Bicentenaria under high Andean conditions.  The research was carried out in the rural community of Canín at Checras district (Lima) altitude of 3880 masl. The climate of the locality is humid and cold, with an annual rainfall of 800 mm and acid soils (pH 5.0) of sandy-clay texture. Five liming treatments and a control without liming were applied to the soil (agricultural lime 500 kg ha-1 and carbonatite 500, 1000, 1500 and 2000 kg ha-1). Agronomic and biochemical characteristics of the tuber were evaluated and sensory analysis was performed for potato frying. Data were analyzed statistica...

Objetivo: Determinar la efectividad de algunos productos para la inducción de resistencia sistémica adquirida en el comportamiento agronómico con la finalidad de mejorar la sanidad general de los cultivos de papa y camote, incrementar sus autodefensas y reducir el impacto de las aplicaciones de agroquímicos. Material y métodos: Se sembraron 3 genotipos de camote (Ipomoea batatas Lam.) en un DBCA con 3 repeticiones durante dos campañas, una en invierno del 2013 y la segunda en el verano del 2013. Adicionalmente se aplicaron 2 inductores químicos de RSA, fosfito de potasio (2.5 ml/L) y ácido salicílico (100 mg/L) más un testigo control sin aplicación. Asimismo, se realizó un experimento bajo invernadero en 2 clones de papa utilizando tratamientos inductores de resistencia sistémica. Resultados: No existieron diferencias estadísticas entre los tratamientos inductores y el test...
