Effect of different level of nitrogen on different plant spacing on growth, yield and quality of kale

Abstract

Many vegetables in the Brassicaceae family are being grown in Prayagraj (Allahabad), yet kale is not well-known and not much research is done on this crop in this region. Kale has a high nutritional and economic value, therefore if grown on large scale may help the farmers to procure a better and extra income compared to other well-known crops. A trial was conducted at the Vegetable Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj (UP) during 2023 to study the “Effect of different levels of Nitrogen and Plant Spacing on growth yield and quality of Kale (Brassica oleracea var. acephala)”, with four different doses of nitrogen i.e.15 kg, 20 kg, 25 kg and 30 kg each arranges at two different plant spacings of 40 cmx25 cm and 50 cm x 35 cm. The results revealed that maximum plant height, leaf area, number of leaves per plant, average head weight, yield per plot, yield per hectare, TSS and ascorbic acid content were found in T8 (Nitrogen = 30 kg and spacing = 40 cm x 25 cm).
