Abstract:
Field experiment was conducted during Rabi, 2022 at Instructional Farm, Department of Agronomy, College of Agriculture, Dapoli, Ratnagiri, Maharashtra in lateritic soils of Konkan to study the effect of nitrogen levels and nano urea on growth, yield and quality of mustard (Brassica juncea) under lateritic soils of Konkan. The treatments comprise of various levels where, main factor (nitrogen levels) viz., 0, 100, 75% of RDN and sub factor (nano urea) viz., 0, 20, 40, 60, 80 ppm @ 30 and 60 DAS. Significantly positive effects and higher values were observed on plant height, number of branches plant^-1, number of functional leaves plant^-1 and dry matter production at 40, 60 and 80 DAS (Days after sowing) of mustard crop with the application of 75% RDN (F₃) and two spray of nano urea @ 40 ppm (N₃) whereas, least values were recorded with untreated control (F₁N₁) treatment combination. Significantly higher seed yield (2083.57 kg ha^-1) and straw yield (3646.24 kg ha^-1) were observed when 75% RDN (F₃) and two spray of nano urea @ 40 ppm (N₃) was applied over other treatments and lower seed and straw yields ware observed with respect untreated (F₁N₁) treatment combination.
