Abstract
To find out the suitable variety of linseed for achieving higher productivity and profitability under different nutrient management practices, a field experiment was conducted during Rabi 2018-19 at Palampur. Twelve treatments comprising of four nutrient management practices (viz. Inorganic (RDF), Organic, Natural and Integrated Nutrient Management) in main plots and three varieties (viz. ‘Him Palam Alsi-2’, ‘Himani’ and ‘Priyam’) in sub plots were evaluated in Split Plot Design with three replications. The soil of the experimental field was silty clay loam in texture, acidic in reaction (pH 5.9) and medium in available nitrogen (243.3 kg/ha), phosphorus (24.7 kg/ha) and potassium (145.4 kg/ha). Results, revealed that among different nutrient management practices, Integrated Nutrient Management being at par with inorganic practice resulted in significantly taller plants with more dry matter, yield attributes, higher uptake of nutrients and thereby higher yield (1184 kg/ha) with highest net return of
21935/ha. However, INM practice has significant advantage over inorganic practice for enhancing microbial count and other soil properties with 7.53 per cent increase in yield. Among varieties, ‘Him Palam Alsi-2’ has significantly more dry matter, number of primary branches, capsules/plant, higher uptake of NPK and superseded all other varieties with significantly highest yield (1169 kg/ha) and maximum net return (
20567/ha). Soil properties were not influenced by different varieties. In integration, variety ‘Him Palam Alsi-2’ sown under integrated nutrient management practice resulted in significantly higher seed yield (1297 kg/ha) and net return of
26429/ha. Thus ‘Him Palam Alsi-2’ along with INM may be recommended for higher sustainable yield of linseed.
