Growth, Productivity, Competitive Ratio, Maize Equivalent Yield, Land Equivalent Ratio, and Profitability of Hybrid Maize as Influenced by Relay Cropping with Mukhikachu (Colocasia esculenta Schott.) during Rabi Season

Relay cropping is a method that increases total productivity through maximum utilization of resources. In this study, we planned field experiment, which was conducted at the Regional Agricultural Research Station, Ishwardi, Pabna during 2016-2017 and 2017-2018 to find out most suitable way relaying mukhikachu (MU) with hybrid maize get benefit. Seven treatments: T1= silking stage (100 DAS), T2 = blister (110 T3 milk (120 T4 dough (130 T5 dent (140 T6 Sole maize, T7 mukhikachu, were compared in study. It found among treatments (relay sole stand), there no significant difference terms yield attributes both base (maize) relay crop (mukhikachu). entire treatment, yielded 10.54-11.30 t ha-1 results 3.28-3.66 MJ m-2day-1 light energy interception 2.68-2.84 LAI DAS) 1534.63-1592.69 g m-2 TDM (140DAS). The 26.88-27.28 system. Maize equivalent (MEY) BCR ranged from 28.48-29.18 2.33-2.39, respectively, amongst treatments. land ratio (LER) treatment produced almost double (1.934-1.996) crops. Farmers can benefit by adopting technology when they grow long-duration crops, lead improved system productivity.
