Effect of organic sources of nutrient and biofertilizers on growth, yield and quality of leafy coriander (Coriandrum sativum L.) under various shade net conditions

A field experiment to understand the effect of organic sources of nutrient and bio-fertilizers on growth, yield and quality of leafy coriander (Coriandrum sativum L.) under various shade net conditions was carried out during summer season of 2019 at College of Horticulture, SDAU, Jagudan, Dist. Mehsana (Gujarat). Experiment laid out in a split plot design consisted three shade net conditions as main plot treatment viz., 50 per cent white shade net, 50 per cent black shade net and 50 per cent green shade net, and sub plot having seven combinations of various sources of organics and bio-fertilizers, i.e., m1 (RDF through chemical fertilizer), m2 (75% nitrogen through FYM), m3 (75% nitrogen through vermicompost), m4 (75% nitrogen through neem cake), m5 (T2 + Azotobacter + PSB + KSM), m6 (T3 + Azotobacter + PSB + KSM) and m7 (T4 + Azotobacter + PSB + KSM), which made 21 treatment combinations and replicated thrice having a plot size of 2.5 × 1.8 m with a spacing of 20 cm between two rows. Observations were recorded on important growth, yield and quality characteristics of coriander. Results revealed that the maximum plant height (19.68, 17.34 and 14.90 cm), number of branches (7.26, 7.55 and 7.18), green biomass yield per plot (2.26, 3.04 and 1.03 kg) at and each subsequent cuttings, respectively, as well as green biomass yield per m2 area (1.96 kg) and per plot (6.34 kg) (m6). As far as quality traits were concerned maximum chlorophyll a, b, total chlorophyll and carotenoid contents (0.86, 1.19, 1.98 and 4.30 mg 100 g-1) were observed with the application of 75 per cent nitrogen through vermicompost + Azotobacter + PSB + KSM) (T6).
