tailieunhanh - Productivity and water expense efficiency of rice (Oryza sativa L.) under different irrigation scheduling in South-west Punjab

A field experiment entitled “Effect of irrigation scheduling on performance and water expense efficiency in rice (Oryza sativa L.) in South-west Punjab” was conducted during the rabi season of 2017 at Research Farm of Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The experiment was laid out in RCBD (Randomized complete block design) with 4 treatments viz., T1: Continuous standing of irrigation water, T2: Irrigation one day after infiltration of pounded water, T3: Irrigation two days after infiltration of pounded water, T4: Irrigation four days after infiltration of pounded water. The results showed that the application of irrigation one day after infiltration of ponded water recorded significantly higher no. of tillers/hill (), plant height ( cm), no. of effective tillers/hill (), panicle length ( cm), number of grains/panicle (), grain yield ( q/ha), straw yield ( q/ha), biological yield ( q/ha) and water expense efficiency ( kg/ha/cm) than other treatments. Application of irrigation one day after infiltration of ponded water do not produced only higher grain yield but also helped to save 27% irrigation water compared to continuous flooding. The findings can be useful for improving rice productivity with less water consumption in Punjab state. | Productivity and water expense efficiency of rice (Oryza sativa L.) under different irrigation scheduling in South-west Punjab
