Performance of new genotype of gobhi sarson (Brassica napus L.) ‘AKMS 8141’ at varying fertility level in mid hills of Himachal Pradesh

Abstract

A field experiment was conducted under All India Coordinated Research Project on Rapeseed-Mustard at CSK HPKV, Shivalik Agriculture Research and Extension Centre, Kangra in rabi 2019-20. The experiment comprised of one test genotype of gobhi sarson ‘AKMS 8141’and three checks, viz., GSL1, Kranti & GSC 6 in main plots and three fertility levels viz., 100, 125 & 150 % RDF (recommended dose of fertilizers ) in subplots were tested in split plot design. The test genotype ‘AKMS 8141’(193 cm) was significantly taller than Kranti by 12 cm and GSC 6 by 38 cm. Significantly more seed yield was recorded by the test genotype ‘AKMS 8141" (1260 kg/ha) being at par with GSC 6 (1249 kg/ha) compared to GSL 1 (996 kg/ha) and Kranti (910 kg/ha) attributed to the higher value of siliquae perplant (366), seeds per siliqua (23.8) and test weight (3.28g). The test genotype ‘AKMS 8141’ having seed oil content of 40.8%, resulted in oil productivity 514.4 kg/ha on par with GSC 6. Significant variation in seed and oil yield was not recorded due to varying fertility level. Thus, it may be concluded that the new genotype of gobhi sarson ‘AKMS 8141’is productive and profitable and may be grown by the farmers of mid hills of Himachal Pradesh.
