Abstract:
The present research entitled “Studies on effect of organic and inorganic nutrients on growth and yield of capsicum (Capsicum annuum L. var. Grossum).” was carried out at the research block of the Medicinal and Aromatic Plant Research Station, Rajendranagar, during Rabi-2020. The experiment was laid in factorial randomized block design with three replications. Results revealed that organic nutrients [Neem cake (1t/ha), Azotobacter (4 kg/ha) + Azospirillum (4 kg/ha), Azotobacter (4 kg/ha) + PSB (4 kg/ha), Azospirillum (4 kg/ha) + PSB (4 kg/ha)], inorganic nutrients (100% RDF, 75% RDF, 50% RDF) and its combinations significantly improved the plant growth and yield parameters. Azospirillum + PSB significantly recorded the maximum plant height (77.66 cm), primary branches per plant (3.68), polar diameter of fruit (9.21 cm), equatorial diameter of fruit (7.20 cm), number of fruits per plant (9.93), fruit weight (105.39 g), fruits yield per plant (1.05 kg), fruit yield per plot (21.37 kg) and fruit yield per hectare (35.64 t). Azospirillum + PSB treated plant also took least number of days taken to 50 per cent flowering (39.61days) and first picking (60.38 days). Among the different levels of inorganic nutrients, 100% RDF through inorganic nutrients recorded significantly maximum plant height (78.99 cm), primary branches per plant (3.78), polar diameter of fruit (9.41 cm), equatorial diameter of fruit (7.33 cm), number of fruits per plant (10.27), fruit weight (107.56 g), fruit yield per plant (1.10 kg), fruit yield per plot (22. 09 kg), fruit yield per hectare (36.81 t). 100% RDF through inorganic nutrients treated plant also took minimum number of days taken to 50 per cent flowering (39.14 days), days taken to first picking (59.96 days). The interaction between organic nutrients and inorganic nutrients sources had shown significant results. Maximum plant height (79.95 cm), primary branches per plant (3.86), polar diameter of fruit (9.61 cm), equatorial diameter of fruit (7.48 cm), number of fruits per plant (9.93), fruit weight (108.32 g), fruit yield per plant (1.15 kg), fruit yield per plot (23.03 kg), fruit yield per hectare (38.32 t), and least number of days taken to 50 per cent flowering (38.70 days), days taken to first picking (59.26 days) was noticed in Azospirillum + PSB in combination with 100% RDF.
