Quantitative and qualitative appraisal of constraints inhibiting the diffusion and adoption of optimized gobhi sarson agronomic practices on heavy soil agro-ecosystems in South-Eastern Punjab

Abstract

Gobhi Sarson is an important winter oilseed crop, offers a viable diversification option in Punjab’s rice–wheat cropping
system. Despite its potential, the adoption of recommended production technologies remains limited in the south
eastern region of Punjab, particularly in Fatehgarh Sahib district characterized by heavy-textured soils. The present
study assessed the extent of adoption of agronomic practices and identified major constraints faced by farmers in Gobhi
Sarson cultivation. A structured survey was conducted over two consecutive rabi seasons, covering 100 farmers from
two blocks- Khamano, and Khera. The results revealed higher adoption of time of sowing (70%), plant protection
practices (74%), and varietal selection (68%), while fertilizer application (38%) showed lower adoption. Major constraints
included weed infestation (MPS: 80.0), non-availability of phosphorus fertilizers (74.6), difficulties in manual harvesting
and threshing (82.0), and fluctuating market prices (75.3). A significant negative relationship (r = –0.29) was observed
between constraints and adoption levels. The study emphasizes the need for timely input availability, mechanization
support, and effective price stabilization. Strengthening extension services and improving access to quality inputs can
significantly enhance Gobhi Sarson adoption and productivity in the region
