Abstract:
A field experiment was conducted during the
rabi season of 2017 on mustard crop (var. DHARA) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P.). To study the effect of integrated nitrogen management on growth and yield of mustard. The experiment consisted of providing 80 kg nitrogen to mustard by supplying 50 kg nitrogen through urea and 30 kg nitrogen either through poultry manure or by farmyard manure or by vermicompost with and without
Azotobacter seed inoculation, which was compared with 80 kg nitrogen supplied through urea alone. Hence, comprising of seven treatments, which were laid out in Randomized Block Design and replicated thrice. The result showed that Application of 50 kg nitrogen through urea + 30 kg nitrogen through poultry manure +
Azotobacter (seed inoculation) gave higher growth attributes
viz., plant height (153.53 cm), plant dry weight (59.95 g), crop growth rate (2.64 g m
-2 day
-1) and higher yield attributes
viz., number of siliqua plant
-1 (365.75), number of seeds siliqua
-1 (14.53), test weight (4.90 gm), seed yield (2.37 t ha
-1), stalk yield (6.62 t ha
-1) and consequently, harvest index (26.35).
