Effect of Nitrogen Fertilization on the Quality of Swiss Chard at Harvest and during Storage as Minimally Processed Produce

2014

The effects of different levels of nitrogen fertilization (0-50-100-150-200 kg ha-1), minimal processing and cold storage (14 days at 4°C) on yield and quality of fresh-cut Swiss Chard (Beta vulgaris L. var. cicla L.) were evaluated. Increasing the level of nitrogen fertilization over 100 kg N ha-1, plants had a higher fresh weight, reduced their dry matter content and resulted taller and leafier. Total and marketable yield increased linearly as increasing nitrogen level. Both nitrate and ascorbic acid content at harvest increased as increasing nitrogen supply. Nitrogen fertilization negatively affected the yield of minimal processing. No effect on appearance and quality loss during cold st…

Role of rotation and nitrogen fertilization on the productive and qualitative response of durum wheat (Triticum durum Desf.)

2012

Correct soil management can improve and/or sometimes restore the fertility of agricultural land. Crop rotations are important to maintain adequate soil organic matter content and to reduce chemical nutritional intake. Qualitative and productive durum wheat response is strongly influenced by soil nutrient availability, necessary for plant growth and development. Nitrogen availability, mainly during the first stage of growth, determines the uptake rate and total nitrogen uptake; later is also responsible of nitrogen translocation from vegetative to reproductive organs, determining yield and grain qualitative characteristics. The aim of the trial was to evaluate cropping system effects and nit…
