Effect of ridging on peanut yield
1984
Teerapong Sinprasit
The experiment was statistically designed as split plot with four replications, having two peanut varieties, Tainan 9 and SK. 38 as two main plots. Five hilling up treatments at 20, 30, 40, 50 and 60 days after emergence (DAE), and two treatments at 20, 30, 40, 50 and 60 days after emergence (DAE), and two treatments of planting peanut on ridge and on flat land without ridging, were used as subplots randomized within each main plot. The objective was to identify the suitable time for hilling up peanuts to increase yield. Samples of plants were collected at 65,75 and 85 DAE and at maturity in order to study the growth,yield components of peanut as affected by ridging treatments. Hilling up increased root length, root dry weight, number of branches, total dry matter, number of pods, pod weight, root dry weight, number of branches, total dry matter, number of pods, pod weight and seed weight significantly when compared to plant receiving no-ridging treatments. Hilling up at 20,30 and 40 DAE increased plants growth and yield when compared to the hilling up after 40 days for both peanut varieties. The most suitable hilling up period was at 40 DAE because ridging at this stage resulted in better plants
