Effect of micronutrients on yield and economics of gynoecious cucumber (Cucumis sativus L) var Kian under naturally-ventilated polyhouse

The economic analysis was conducted for cultivation of gynoecious cucumber var Kian under naturally-ventilated polyhouse during Kharif season of 2014–2015. The experiment consisting of twenty seven treatments was laid out in factorial randomized block design with three replications. The common cost of cultivation for growing cucumber under naturally-ventilated polyhouse was Rs 131.5/m². The maximum yield per plant (5.62 kg), net income of Rs 498.17/m² with highest B-C ratio of 3.71 was obtained with foliar application of treatment B₂Zn₂Fe₂(boron at 40 ppm + zinc at 40 ppm + iron at 80 ppm) and it was found significantly superior over control.
