Abstract: Solar powered irrigation system (SPIS) has emerged as a promising technology in Bangladesh. The aim of this study to find the financial and environment importance of SPIS. This study also analyzes the factor demand and elasticity of substitute for SPIS irrigation in Boro rice production. The financial analysis indicate that SPIS user had significantly higher gross return, net return and benefit cost ratio (BCR) than diesel powered irrigation system (DPIS) user. The value of BCR for SPIS user was found 1.313 and 1.029 for DPIS user. Replacing half of diesel powered irrigation system can reduce more than one million carbon emission in environment from agricultural source. The result also revealed that irrigation system is highly inelastic and the result showed that an increase and decrease in price of irrigation wouldn’t have significant impact on demand of irrigation. The result indicates that for Boro rice production farmer had to use required amount of irrigation in field. Complementary relationship was found between seed and human labour, irrigation and human labour. Substitute relationship was found between machinery and seed, machinery and irrigation, machinery and human labour, machinery and fertilizer, seed and irrigation, seed and fertilizer, irrigation and fertilizer, human labour and fertilizer.
