Abstract
A field experiment was conducted to study the effect of Intigrated nutrient management (INM) modules on indian mustard (Brassica juncea L.) in Western
U.P. ,variety Pusa Vijay at Crop Research Centre (CRC), Main Campus, modipuram Meerut, during rabi season, 2020-21. The soil of experimental field was sandy loam texture, alkaline in nature with pH (8.25), low in organic carbon (0.42%) and available nitrogen (181.60 kg/ha), available phosphors (16.50 kg/ha), available potassium (230.47 kg/ha), available sulphur (7.38 kg/ha). Ten treatments of different nutrient management practices consisting T1 Control, T2 100% RDN (120 kg. N/ha), T3 75% RDN, T4 75% RDN + 25% Vermicompost (VC), T5 75% RDN + 25% Poultry Mannure (PM), T6 75% RDN + 25% Press Mud Compost (PMC), T7 75% RDN + 25% Through [ VC , PM (1:1) ], T8 75% RDN + 25% Through [VC, PMC (1:1) ], T9 75% RDN + 25% Through [PM , PMC (1:1) ], T10 75% RDN + 25% Through [VC , PM, PMC (1:1:1) ]. were tested in randomized block design with three replication. The experimental results revealed that maximum growth parameters (plant height, branches plant-1, dry matter accumulation and leaf area index), yield attributes (siliqua length, siliqua plant-1, seeds siliqua-1 and test weight), yield (grain and stover), nutrient uptake (N,P,K and S) by grain and stover and available soil nutrient (N,P, K and S) were recorded with application of 75% RDN + 25% Through [VC , PM, PMC (1:1:1) ] higher than the rest of the treatments. The increment in seed yield with application of 75% RDN + 25% Through [VC, PM, PMC (1:1:1)] was
130.98 % over control. Maximum gross return, net return were recorded with the application of 75% RDN + 25% Through [VC , PM, PMC (1:1:1) ], however B:C ratio was lower than the use of RDF only but in application of vermicompost, press mud compost and poultry mannure improved the physio chemical properties of soil which may improved the sustainability of production system.
