Effect of Different Treatment Modules on Seed Yield and Quality in African Marigold (Tagetes erecta L.)

The present investigation was carried out at the experimental farm of Department Seed Science and Technology, Dr YS Parmar University Horticulture Forestry, Nauni, Solan (HP)-173 230 during 2018 2019. treatment modules comprising different doses Jeevamrit applied as drench (25ml/m2, 50ml/m2, 75ml/m2 100 ml/m2) foliar spray (5%, 10%, 15% & 20%) 15 days interval, alternatively + Brahmastra @ 2.5 % Neemastra 7 along with RDF, untreated control an organic module based on Trichoderma viride. field experiment conducted in Randomized Block Design (RBD) 19 treatments replicated thrice. Although, maximum values for number seeds per capitulum (268.12), seed yield plant (14.74 g), plot (176.90 hectare (327.59 kg), 1000 weight (2.56 germination (85.13 %), seedling length (12.66 cm), fresh (0.55 dry (7.78 mg), SVI-I (1077.68), SVI-II (662.55) were recorded M18 (RDF (100% NPK) FYM 5 kg/m2) it found to be statistically par M16 (Drenching ml/m2 Foliar application 20 intervals, alternatively) which had highest speed (33.36).
