Abstract
Carrot is one of the major vegetable crops grown throughout the world and considered to be an important economical vegetable as it has large yield per unit area. The inclusion of carrots in human diet is highly appreciated due to high nutritional and positive impact on human health and immunity systems. This is cheaply available and is equally consumed by poor and rich people in India. The popularity of carrot is increasing day by day due to its high nutritive values and adaptability in diversified agriculture. Plant spacing is one of the important factors for the increased production of carrot. To augment the potential yield of carrot, nutrient management plays a vital role. Different types of fertilizer affect the yield and nutritional quality of carrot. Crop sown at 15 and 30 cm row spacing recorded statistically an equal root length but significantly longer than broadcasting. Carrot sown at 30 cm row spacing confirmed significantly the maximum root girth and it was the lowest when carrot sown by broadcasting. Application of 80% RDF recorded the maximum root length as well as girth and was at par with 100% RDF but these both the levels were significantly superior to the maximum fertility level i.e. 120% of RDF. Both the line sowings were at par and recorded significantly higher root yield than broadcasting on pooled basis. Application of 80% RDF recorded the significantly the maximum root yield of carrot and remain at par with 100% of RDF. The root weight augmentation could be due to the increased vegetative growth and hence increased food production and assimilation into parts. But with excess application of N-fertilizer more of above ground vegetative growth is favored than root growth, so that low root weight could result at higher level of N fertilizers. However, narrow spacing and higher fertility levels increased fodder yield. Application of 80% RDF recorded the maximum gross (Rs.2,12,8001ha) and net profit (Rs.1,67,588/ha) as well as BCR (3.71) values.
