Garima Diwan, BP Bisen and Pankaj Maida Abstract The present investigation was carried out during Rabi season of 2017-2018 at the Horticulture complex, Department of Horticulture, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.). The treatment combinations consisting of five levels of nitrogen (50, 60, 70, 80 and 90 kg N ha -1 ) and three row spacing (30, 40 and 50 cm) replicated thrice. Highest growth characters were higher in the treatment combination N5S3 (N: 90 kg N ha -1 , S: 50X10 cm) viz., number of branches, total biomass production of the plant on dry weight basis(g), days taken to 50% flowering, Days taken to maturity and yield attributes the treatment combination N5S3 (N: 90 kg N ha -1 , S: 50X10 cm) viz., umbels plant -1 , umbellets plant 1 , seeds umbel -1 , test weight (g), Seed yield plant -1 (g). Maximum seed yield of 16.66 q ha - 1 was obtained in coriander (Jawahar Dhaniya -2) with treatment combination N5S1 (N: 90 kg N ha -1 , S: 30X10 cm) and maximum net return of Rs 79,221.06 ha -1 and cost benefit ratio 1:3.11. Keywords: coriander (Coriandrum sativum L.), growth, nitrogen, row spacing, seed yield Introduction Coriander (Coriandrum sativum L.) is one of the most important vegetable, spice and medicinal plant. It is small seeded aromatic annual herb of family apiaceae. Coriander plant gives two primary products that are used for flavouring purposes: fresh green herb and spice. Coriander leaves are being used in cooking, flavouring, beverages etc., and seeds are being used for preparing value added products such as coriander powder, dhana dal, condiment, oleoresin, essential oil, medicine and cosmetic industries. The essential oil content of locally available seeds of coriander is 0.2–0.3 per cent whereas major chemical constituents of essential oil are d-linalool, linalyl acetate along with other important constituents such as thymol, geraniol, carophyllene and pinene [1] . It has traditionally been used for its anti- inflammatory, anti-diabetic, cholesterol lowering effects and also is good appetizer health benefits of coriander include treatment of swellings, diarrhoea, mouth ulcers, anaemia, digestion, menstrual disorders, small pox, eye care, conjunctivitis, skin disorders, blood sugar disorders, protects and soothes liver etc. India is the largest producer, consumer and exporter of coriander in the world. In India the major coriander growing states are Rajasthan, Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka, Madhya Pradesh, Bihar, Uttar Pradesh [2, 3] . The area under coriander cultivation in India is 663 thousand hectare and production is 609 thousand MT and in Madhya Pradesh, coriander is cultivated over an area of 200 thousand hectare and production is 102.50 thousand MT [4] . Among the primary nutrients, nitrogen has a considerable effect, not only on quality of produce but on quantity of produce also. It is involved in photosynthesis, respiration, carbohydrate synthesis and protein synthesis. It impart the dark green colour of the leaves, promotes vigorous vegetative growth and more efficient use of available inputs finally leads to higher productivity. The various agronomic practices such as application of nitrogen fertilization and plant spacing are the important deciding factors influencing growth and yield parameters of coriander. Coriander plant could be used as indicator plant for rapid determination of N, P and K deficiency of Indian soils. Optimum crop geometry is one of the important factors for crop growth and production because of efficient utilization of resources. The aim of this work was to evaluate, growth and yield of coriander as influenced by different levels of nitrogen and plant spacing.
