Abstract
A field experiment was carried out at College Farm of N. M. College of Agriculture, Navsari AgriculturalUniversity, Navsari to study the ââ¬ÅResponse of date of sowing and varieties on growth and yield of mustard(Brassica juncea L.) under South Gujarat conditionââ¬Â. 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).
