Integrated nutrient management in coriander (Coriandrum sativum)

The field study was carried out to study the integrated nutrient management in coriander (Coriandrum sativum L.) var. GCo-3” during rabi, 2023–24 at Regional Horticultural Research Station, ASPEE College of Horticulture, NAU, Navsari, Gujarat, India. The experiment was conducted in randomized block design with ten treatments and three replications consisting of viz. T₁: FYM 10 t/ha and 100 % RDF (60:30:00 kg NPK/ha), T₂: FYM 5 t/ha + 75 % RDF, T₃: FYM 10 t/ha + 50 % RDF, T₄: vermicompost 2 t/ha + 75 % RDF, T₅: vermicompost 4 t/ha + 50 % RDF, T₆: biocompost 2 t/ha + 75 % RDF, T₇: biocompost 4 t/ha + 50 % RDF, T₈: FYM 5 t/ha + 50 % RDF +1 % novel organic liquid nutrients T₉: vermicompost 2 t/ha + 50 % RDF + 1 % novel organic liquid nutrients and T₁₀: biocompost 2 t/ha + 50 % RDF + 1 % novel organic liquid nutrients. The application of FYM 5 t/ha + 50 % RDF + 1 % novel organic liquid nutrients (T₈) gave maximum plant height (24.17 cm, 60.71 cm, 112.15 cm and 116.29 cm), highest number of primary branches/plant (1.990, 2.67, 4.07 and 4.27), total number of branches/plant (7.60, 9.53, 11.80 and 15.40), petiole length (21.18 cm, 18.68 cm, 13.50 cm and 8.48 cm) and leaf length (3.52 cm, 3.67 cm, 3.77 cm and 3.85 cm) 30, 60, 90 days and at harvest after sowing, respectively. Maximum number of umbels/plant (17.47), number of umbellates/umbel (5.87), number of seeds/umbellates (7.93), highest seed weight/plant (5.94 g), test weight of (000 seed weight) (14.33 g), seed yield (2002.93 kg/ha) and straw yield (2541.67 kg/ha) as well as oil yield (14.21 kg/ha) were observed under application of FYM 5 t/ha + 50 % RDF + 1 % novel organic liquid nutrients (T₈). The highest benefit:cost ratio (1.79) and maximum net realization (1,35,062 %/ha) were obtained under FYM 5 t/ha + 50 % RDF + 1 % novel organic liquid nutrients (T₈). Whereas, application of FYM 10 t/ha + 50 % RDF (T₃) improved soil nutrient status.
