Abstract
A field experiment was conducted during the Rabi season 2020-21 at the
Experimental Farm and laboratoryof the Department of Seed Science and Technology, CSK
Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the effect of integrated nutrient
management on seed yield and quality of wheat (Triticum aestivum L.) under mid hill
conditions of Himachal Pradesh. The experiment consisted of ten treatments viz. T1 (100%
RDF (120:60:30 kg/ha)), T2 (FYM @ 10t/ha + 75%RDF), T3 (FYM @ 10t/ha + 100%RDF),
T4 (Vermicompost @ 5t/ha + 75% RDF), T5 (Vermicompost @ 5t/ha + 100% RDF), T6
(FYM @ 5 t/ha + Vermicompost @ 2.5 t/ha + 75% RDF), T7 (FYM @ 5t/ha +
Vermicompost @ 2.5t/ha + 100% RDF), T8 (FYM @ 5t/ha + Vermicompost @ 2.5t/ha), T9
(FYM @ 5t/ha + Fortified Vermicompost @ 2.5t/ha) and T10 (FYM @ 10t/ha +
Vermicompost @ 5t/ha). These ten treatments were tested in randomized block design with
four replications. The results revealed significantly highest growth parameters (plant height
(92.0 cm) and dry matter accumulation (1141.8 g/m²)), yield attributes (number of tillers/m²
(240.55), number of spikelets/m² (218.30), spike length (13.0 cm), spikelets/spike (16.5),
seeds/spike (36.6) and 1000 seed weight (45.82g)), seed yield (3925.8 kg/ha) and seed quality
parameters (seedling length (18.7 cm), seedling dry weight (188.0 mg), vigor index-I (1789.4)
and vigor index-II (17989.7)) was recorded with the application of vermicompost @ 5t/ha
along with 100% RDF treatment T5 which was at par with treatment T3 (FYM @ 10t/ha +
100% RDF) for most of the above mentioned parameters. Further, data on economic part
revealed that though highest gross return (Rs.146325.9) was recorded with treatment T5, but
higher net return (Rs.89681.1) and B:C ratio (1.65) was recorded for treatment T3 as
compared to T5. Hence, it can be concluded that both treatments viz. T5 and T3, can be
recommended for quality seed production of wheat in mid hill conditions of Himachal
Pradesh
