Yield gap in mulberry and cocoon production under rainfed and irrigated conditions in Chamarajanagar District, Karnataka State

Mr. M. Raju, Dr. B. Sannappa

Abstract :

An investigation has been conducted to know the extent of yield gap existed in mulberry and cocoon production among rainfed and irrigated sericulture farmers in Chamarajanagar district of Karnataka state, India, in order to find the ways to reduce the gap and improve upon the productivity of sericulture. In mulberry production, potential yield, potential farm yield and actual yield of farmers varied considerably between rainfed and irrigated conditions. Yield gap–1, yield gap–2 and index of yield gap were very narrow under rainfed condition when compared to irrigated condition with fewer gaps among big farmers over medium and small farmers. Similarly, index of realized potential yield and index of realized potential farm yield were also better with rainfed farmers over irrigated farmers being higher yield realization among big farmers as compared to medium and small farmers. In silkworm cocoon production, potential yield was same for both rainfed and irrigated conditions. Potential farm yield and actual yield of farmers were higher with irrigated farmers over rainfed farmers. The variation existed in yield gap–1, yield gap–2 and index of yield gap were less under irrigated condition over rainfed condition with least gap among big farmers as compared to medium and small farmers. Similarly, index of realized potential yield and index of potential farm yield were superior under irrigated farmers over rainfed farmers with higher yields among big farmers over medium and small farmers.
