ABSTRACT
The present investigation titled, “Standardization of natural farming module for seed
production in Sweet William (Dianthus barbatus L.)” was carried out at the Khaltoo experimental farm
of Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry,
Nauni, Solan (HP)-173 230 during 2018 to 2020 to find a suitable treatment module for obtaining better
plant growth, flowering seed yield and quality of Sweet William. The treatment modules comprised of
different doses of Jeevamrit applied as drench at monthly interval and foliar spray at 15 and 20 days
interval + Brahmastra @ 2.5 % and Drekastra @ 2.5 % at 10-12 days interval, alternatively. Field
experiment was laid out in Randomized Block Design (RBD) with 14 treatment modules replicated thrice
and the laboratory studies were conducted with four replications. Among different treatment modules,
earliest flowering (103.21 days), maximum values for plant height (48.81 cm), plant spread (36.81 cm),
number of inflorescences per plant (12.02), diameter of inflorescence (10.14 cm), number of florets per
plant (265.37), duration of flowering (46.81 days), number of seeded capsules per plant (235.14), number
of seeds per capsule (54.01), seed yield per plant (11.43 g), seed yield per plot (102.87 g), 1000 seed
weight (0.98 g) as well as minimum number of non-seeded capsules per plant (31.84) were recorded in
treatment module M5 {Drenching with Jeevamrit @ 100 % at monthly interval + Foliar application of
Jeevamrit @ 30 % at 15 days interval + Brahmastra @ 2.5 % and Drekastra @ 2.5 % at 10-12 days
interval, alternatively}. Similarly, maximum germination (95.38 %), speed of germination (12.20),
seedling length (7.64 cm), seedling dry weight (0.57 g), SVI-I (728.17), SVI-II (54.05) and lowest seed EC
(0.153 dS/m) were also obtained in M5. The highest viable microbial count i.e. bacteria (41.61 × 107 cfu/g
soil), fungi (12.76 × 102 cfu/g soil) and actinomycetes (32.78 × 103 cfu/g soil) were found under treatment
module M5. However, maximum nitrogen (541.20 kg/ha), phosphorus (80.87 kg/ha) and potassium (302.01
kg/ha) were found under treatment module M13 {RDF (100 % NPK) + FYM @ 5 kg/m2}.
