Yield Gap Analysis through Cluster Front Line Demonstration in Blackgram at Tiruchirapalli District

Abstract

Background: Black gram is one of the important crops among the pulses. Rice–blackgram cropping system is very common in Tamil Nadu. The traditional practice of broadcasting of seeds in the standing crop of rice does not ensure uniform plant population and moisture which results in poor crop growth and yield. Technology gap is a major problem in increasing blackgram production in Tiruchirapalli district of Tamil nadu State. So far, no systematic effort was made to study the technological gap existing in various components of blackgram cultivation. This project was implemented in Krishi Vigyan Kendra (KVK) with main objective to increase the production and productivity through Cluster Frontline demonstrations (CFLDs) with latest technologies. Methods: The Cluster front line demonstration s were conducted with the objective of increase in pulse production. The five village of fifty nine Frontline demonstrations on blackgram (MDU-1) variety was laid out in an area of 50 hectares in farmer’s field in Ayelapettai, Jadamangalam, Sirugamani, Peruvanallur and Anjalam of Tiruchirapalli district in Tamil Nadu. The inputs i.e. distributed are blackgram (MDU-1) variety seed along with mechanized sowing, Result : There was 81.50 per cent increase in yield observed in demonstration plot over farmers’ practice. It was observed that potential yield can be achieved by imparting scientific knowledge to the farmers, providing the quality need based inputs and proper application of inputs. Combination of technical inputs viz., designer seeds, application of TNAU pulse wonder and biofertilizers with scientific interference have increased the potential yield of a crop.

“…Hence there is an immediate need to replac e traditio nal c ultivatio n prac tices with smart cultivation practices through Frontline Demonstrations (FLDs). FLDs are a novel strategy with the goal of performing demonstrations in wider areas on farmers' fields and raising farmer knowledge about the sustainable crop production technology with a low cost (Amuthaselvi et al, 2023). To the best of our knowledge, no studies have been documented in Andhra Pradesh, specifically within the Scarce Rainfall Zone (SRZ), that focus on groundnut frontline demonstrations (FLDs) in incorporating the modern production technologies.…”
