Abstract:
A field experiment was conducted during Rabi season of 2021 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, and Uttar Pradesh, India. The soil of experimental field is Sandy loam in texture, nearly neutral in soil reaction (pH 7.0). To determine the “Effect of nitrogen and boron on growth and yield of Mustard (Brassica juncea L.)” The treatments consisted of nitrogen and boron viz., Nitrogen levels at 70 kg/ha, 80 kg/ha and 90 kg/ha and Soil application of Boron at 1 kg/ha, 1.5 kg/ha and 2 kg/ha whose effect is observed in Mustard. The Experiment was laid out in Randomized Block Design with Nine treatments Replicated thrice. The results obtained that the treatment 8 with (Nitrogen 90 kg/ha + 1.5 Boron kg/ha)was recorded significantly maximum plant height (181.90 cm), Number of Braches (11.17) dry weight (31.60 g/plant), number of siliqua per plant (242.00),number of seed per siliqua (11.33), Test weight (4.44), seed yield (1.97), stover yield (4.87 t/h), harvest index (28.81).The results obtained with the treatment of T8(Nitrogen 90 kg/ha + 1.5 Boron kg/ha) was recorded maximum crop growth rate (13.81g/m2/day) and relative growth rate (0.03g/g/day).The results obtained with the treatment of T8 recorded higher gross return (137900 INR/ha), net return (92999 INR/ha) and benefit cost ratio (B:C) (2.09). The results obtained with the treatment of T9 recorded higher cost of cultivation (47449 INR/ha).
