TAILIEUCHUNG - Effect of different transplanting dates on productivity and water expense efficiency in rice (Oryza sativa L.)

A field experiment entitled “Effect of different transplanting dates on productivity and water use in rice (Oryza sativa L.)” was conducted at Research Farm, Department of Agronomy, Guru Kashi University, Talwandi Sabo during Kharif season 2017 and 2018. The experiment was conducted in randomized complete block design with four transplanting dates (June 25, July 5, July 15 and July 25), replicated with five times. The soil of the experimental field was loamy sand, with neutral in reaction, low in organic carbon and available nitrogen, medium in available phosphorous and high in available potassium. Transplanting crop on June 25 gave maximum plant height and number of tillers than other transplanting dates. Transplanting paddy crop on June 25 gave significantly higher yield attributes . effective tillers, number of grains per panicle, panicle length, 1000-grain weight, grain yield, straw yield and harvest index than other transplanting dates. Early paddy transplanting (June 25) obtained higher grain yield than later transplanting date (July 25). June 25 resulted in more water use ( cm) followed by July 5 ( cm), whereas July 25 recorded the lowest water use ( cm). Transplanting paddy on June 25 recorded highest water-expense-efficiency as compared to other transplanting dates but it was statistically at par with July 5. | Effect of different transplanting dates on productivity and water expense efficiency in rice (Oryza sativa L.)
