RESPONSE OF DATE OF SOWING AND VARIETIES ON NUTRIENTUPTAKE AND ECONOMICS OF MUSTARD (BRASSICA JUNCEAL.) UNDER HUMID CLIMATIC CONDITIONKamaliya, Y.H., Patel, H.F., Sutariya, M.R. and Patel, S.P.
A field experiment was carried out at College Farm of N. M. College of Agriculture, Navsari AgriculturalUniversity, Navsari to study the âResponse of date of sowing and varieties on growth and yield of mustard(Brassica juncea L.) under South Gujarat conditionâ. The experiment was conducted with randomize blockdesign with factorial concept (FRBD) replication three times and nine treatments combinations, comprisingtwo factors with three date of sowing viz., D1: (19th November), D2: (3rd December) and D3: (17th December)and three varieties viz., V1: (GM-3), V2: (GDM-4) andV3: (GDM-5). Effect of date of sowing innutrient contentand uptake. Significantly maximum nitrogen content in seed (2.73 %), nitrogen content in stover (0.93 %),nitrogen uptake by seed (61.78 kg/ha), nitrogen uptake by stover (44.85 kg/ha), phosphorus content inseed (0.63 %), phosphorus content in stover (0.12 %), phosphorus uptake by seed (14.31 kg/ha), phosphorusuptake by stover (5.86 kg/ha), potassium content in seed (0.74 %), potassium uptake by seed (16.75 kg/ha)and potassium uptake by stover (62.85 kg/ha) was recorded with treatment D1 (19th November). Effect ofvarieties in nutrient content and uptake. Significantly higher nitrogen content in seed (2.69 %), nitrogencontent in stover (0.91 %), nitrogen uptake by seed (56.39 kg/ha), nitrogen uptake by stover (42.15 kg/ha),phosphorus content in seed (0.61 %), phosphorus content in stover (0.11 %), phosphorus uptake by seed(12.77 kg/ha), phosphorus uptake by stover (5.31 kg/ha), potassium content in seed (0.72 %), potassiumuptake by seed (15.04 kg/ha) and potassium uptake by stover (58.81 kg/ha) was recorded with treatmentV2 (GDM-4). Effect of date of sowing and varieties in economics. Significantly highest net realization of(61937 /ha) with B:C Ratio of 3.70 was obtained with treatment D1V2 (19th November, GDM-4).
