Growth, yield and essential oil of coriander (Coriandrum sativum L.) variety ACr-2 as influenced by various nutrient levels and crop geometry

Abstract

A field experiment was carried out Rabi season of 2017-18 at research farm of ICAR-NRCSS, Ajmer, Rajasthan to study the growth, yield and essential oil characterization of coriander variety Ajmer Coriander-2 (ACr-2) as influenced by nutrient levels and crop geometry. The experiment was laid out in Factorial Randomized Block Design with four replications. The experiment was comprises three treatment of each crop geometry and nutrient management. Crop geometry G1 (30 cm x 15 cm), G2 (30 cm x 10 cm) and G3 (30 cm x 5 cm) with nutrient levels N, P2O5 and K2O of kg/ha F1 (40:20:10), F2 (50:25:15) and F3 (60:30:20). The results revealed that the maximum plant height (91.38 cm), primary branches per plant (10.90) and secondary branches per plant (13.28) were recorded with application of 60:30:20 kg/ha NPK and crop geometry of 30 cm x 10 cm. Similar trends were found in yield attributes like number of umbel per plant (34.09) and number of umbellates per umbel (5.91). Seed yield per hectare (1271.25 kg/ha) and essential oil yield (6.74 kg/ha) was also observed with application of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm. Based on the results it is concluded that nutritional level of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm is better for realizing higher seed yields of coriander variety ACr-2.

Growth and yield of AGCr-1 coriander affected by plant geometry and nutrition

“…The reduced intensity of light at the base of the plant might have hastened elongation of poorer internodes leading to increased height of the plants. The recorded crop behaviour under closer spacing is in solid agreement with the results of Diwan et al (2018) and Lal et al (2020), where they reported that in various crops up to a certain level of population, plants grow fast due to self shading but beyond this, elongation is ceased due to reduced photosynthetic activity.…”

“…The efforts like nutrient management and crop breeding programs are important to get better seed yield due to its higher demand for use in confectionery, perfumery and medicine. Application of nutrients at optimal level and geometry of crop (row to row and plant to plant spacing) are the key factors to improve the seed yield of this important spice crop (Lal et al, 2020) The yield levels can be enhanced with the application of optimum nutritional doses and sowing of the crop at appropriate spacing. Since Ajmer Green Coriander-1 (AGCr-1) is a newly developed variety, it was felt that it is necessary to study the response of this variety to the application of different levels of major nutrients (Nitrogen, phosphorous and potassium) and different plant geometry for vegetative growth, yield attributing characters and seed yield.…”

NPS Fertilizer and Spacing Effects on Yield and Quality of Coriander (Coriandrum sativum L.)

“…Despite Ethiopia being a centre of primary diversity for the crop 8 , the attention given so far in research and development was very limited. Moreover, crop production remained low compared to its potential yield, which might be due to the deficiency of essential nutrients including nitrogen and phosphorus 19 . In Ethiopia, farmers have been producing different crops including coriander using the blanket recommendation of urea and DAP fertilizers 20 .…”

Seed Yield and Economic Returns in Coriander in Relation to Different Nutrient Combinations

“…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 [7]. Green leaf is having high essential oil with good aroma and flavour [8]. The essential oil content in seeds of coriander is 0.47-0.53 per cent whereas major chemical constituents of essential oil are linalool, linalyl acetate along with other important constituents such as thymol, geraniol, carophyllene and pinene [8].…”
