Growth and Yield of Transplant Aman Rice (BRRI dhan38) as Affected by Weeding and Zinc Level

The study was conducted at the Agronomy Field Laboratory Department of Agronomy and Agricultural Extension, University of Rajshahi, during the period of July 2019 - December 2019 to study the effect of zinc and weeding on the yield of transplant Aman rice (BRRI dhan38). The experiment consisted of two factors i.e., i) four weeding treatment viz. (control), 1, 2 and 3 hands weeding (at 20, 40 and 60 DAT) and ii) four levels of Zinc treatments (0, 5, 10, 15 kg Zn ha-1). The study was conducted in a Randomized Completely Block Design (RCBD) with three replications. The area of each unit was 10m2. Results revealed that the effect of weeding was significant on plant height, number of tiller hill-1, number of effective and non-effective tiller hill-1, panicle length, number of grain panicle-1, number of effective grain panicle-1, number of non-effective grain panicle-1, weight of 1000 grain, grain yield and straw yield. Among the different weeding regimes the highest result obtaind from the three weedings (completely weed-free condition). The lowest grain yield and yield characters that contributed were produced from no weeding condition. On the other hand, zinc treatment had a significant effect on yield parameters expect the number of non-effective grain panicle-1. Among the different zinc treatment, the maximum grain yield was gained from the fourth level of zinc (15 kg Zn ha-1) and the minimum grain yield was produced from control treatment (0 kg Zn ha-1) From the results, it may be said that four weedings with 15 kg Zn ha-1 is better for transplanted aman rice yield (BRRI dhan38).
