Abstract

A field experiment was conducted during the Kharif season of 2013 to study the effect of constraints of various input resources on growth and yield of rice at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The experiment consisting eight treatments viz., T1: Full recommended package (FRP), T2: FRP – Fertilizer (Fert.), T3: FRP – Plant protection (PP), T4: FRP – Weed management (WM), T5: FRP – (Fert. + PP), T6: FRP – (Fert. + WM), T7: FRP – (PP + WM) and T8: FRP – (Fert. + PP + WM). Results revealed that the full recommended package (T1) was found to be better in terms yield and economics over all other treatments. Among various input resource constraints full recommended package (T1) recorded significantly highest grain (45.18 q ha-1) and straw (55.26 q ha-1) yield over all other treatments, except treatment T4. From the economic point of view, gross returns (Rs. 67522.17 ha-1), net returns (Rs. 7773.49 ha-1), and B: C ratio (1.13) were higher under treatment full recommended package (T1) over rest of the treatments, except treatment T4. The skipping of plant protection measures from full recommend package resulted maximum reduction in yield.
