Growth and yield of irrigated mustard (Brassica juncea (L.) Czern and Coss) cv. NRC-HB-101 as influenced by nutrient sources and secondary nutrients in South Eastern Coastal plain agro-climatic Zone of Odisha

Abstract

A field experiment entitled “Growth and yield of irrigated mustard (Brassica juncea (L.) Czern and Coss) cv. NRC-HB-101 as influenced by organic nutrient sources and secondary nutrients in South Eastern coastal plain agro-climatic zone of Odisha was conducted during the rabi season 2022-23 at the Agriculture Research Station, Binjhagiri of Faculty of Agricultural Sciences, SOADU, Bhubaneswar, Odisha. The experiment was laid out in a split-plot design with three replications. The treatments comprised of organic nutrients (RDF, Farm Yard Manure @5tonnes/ha and Vermicompost @2.5 tonnes/ha) along with the RDF assigned in the main plot and four secondary nutrients (control, lime @0.2 LR, sulphur @ 45 kg/ha and combination of lime 0.2LR and sulphur @45kg/ha was assigned in the subplots. The soil of the experimental plot was sandy loam in texture with pH5.8, low in organic carbon (0.45%) available nitrogen 130 kg/ha phosphorus 14.67kg/ha, sulphur 27.21 ppm and available potassium 132 kg/ha. The test variety used in this experiment was NRCHB-101(110 days). The recommended dose of fertilizer (RDF) was (80:40:40 N:P2O5:K2O kg/ha). From the field experiment it was observed that application of [email protected]/ha increased the growth attributes like plant height (188.90 cm), number of primary (5.50) and secondary branches (11.60), LAI (5.48) and dry matter (55.10g/plant) and the yield attributes i.e number of siliqua/plant, seeds/ siliqua and test weight (g) which was at par with the application of RDF+FYM @5 tonnes /ha. Similarly, among the secondary nutrients, combined application of lime 0.2LR and sulphur@45kg/ha had the highest plant height, branches, LAI dry matter and other yield attributes i.e. no siliqua /plant, seeds/siliqua and test weight. The seed yield (18.63q/ha), stover yield(59.57q/ha), harvest index of 33.94 and oil yield of 12.13q/ha was recorded with the combined application of RDF +VC @2.5 tones /ha along with lime @0.2LR and sulphur @45kg/ha.
