Technology Elements for Irrigated Pepper (Capsicum annuum L.) growth in Field Cultivation Conditions

摘要

Vegetable plants are characterized by very high water content - 85-90%, with water control between 2500 and 4000 m3/ha (Luca and Nagy, 1999). Pepper has a shallow root system with high water requirements, so it requires irrigation during the growing season in order to obtain large and turgid fruit, characteristic for the variety. The research regarding the technology elements for irrigated pepper (Capsicum annuum L.) was installed in the Plaiuri Field, Cluj County, in the climatic Transylvania conditions using seven cultivars (Tab. 1), which were distributed in 4 experimental parcels (the surface of a parcel is 82 m2) on which were applied 4 different experimental technologies, with 3 repetitions (n=3). Plants were irrigated by drip irrigation method, after were made the analysis physical and hydro-physical analysis of the soil. The moment of watering application was determined using the Soil tensiometer method, observed every 10 days, beginning with one decade before planting stock in field, at 25 cm down to 50 cm. The parameters observed were: height and type – for plant; length, diameter, shape, and number of cells, wall and color – for fruit characteristics (Amati et al., 2002).
