Sweet Potato Propagation with Jason Griffin


Well, welcome to the Kansas State University John C pair horticultural center Beautiful hundred and twenty acres just outside of Haysville Kansas, which is a little south of Wichita Kansas and we are a research and extension facility for the Department of horticulture and natural resources at Kansas State University and one of the unique things that we do Here is we grow certified organic sweet potatoes and sweet potato slips We do this in an effort to promote sweet potatoes for as a really viable crop for Kansas You’ve got the right soils Kansas is a perfect climate for growing sweet potatoes So we produce our sweet potato slips. We ship those across the country We grow our own sweet potatoes to provide our own slips for the following year And we have enjoyed the sport of north central sare grant which we have been investigating Post-harvest handling of slips to see how long we can improve the shelf-life of these slips And we’ve also been looking at the potential for growing slips in high tunnels if a grower has some extra space in high tunnels how efficient is It to use that space to produce sweet potato slips What is the quality of those slips and what is the shelf life of those slips? Thus those are questions We’re sort of trying to answer with our with our North Central Sarah Sarah grant highly nutritious crop makes that it’s Kansas beautiful place to grow it any place It’s got a nice sandy soils and nice warm summers like we’re having this year And a super tattle slip is nothing more in the spring we put a sweet potato on the ground that we have stored we cover them with soil and Like you would expect us potato or super to do that They send up shoots the shoots get eight to ten inches tall We cut them off and ship those out and that shoot that we cut off that’s 18 inches tall. That is a slip So sweet potatoes could It could have a very bright future here in Kansas. As far as especially as far as sustainability goes It’s a different sort of crop. It’s a root crop. It’s not a leaf crop that’s harvested It fits well into it into a rotation But there are potentials for larger economic growers using them. In fact this year we have worked with one of the large Center pivot growers who was looking at growing sweet potatoes in the corners of his field where the center pivot doesn’t grow And so there’s a it’s a nice option. It’s an it’s a nice crop again to sort of fit into a low maintenance Trillo maintenance sort of operation So we’ve had really good success with our organic production of sweet potato cents remarkably good success weeds are our biggest problem But we we manage them through through cultivation and some good old manual labor but some of the common issues associated with Sweet potatoes such as wireworms and scurf which is a pretty devastating disease for sweet potatoes We have had no issues with those in the last ten years at all that we believe our crop rotation Field only gets sweet potatoes every third year and in between there, we’ve got cover crops. So we think we are Beating back those very common sweet potato pests to through crop rotation. It’s been very successful for us we are hoping through our operations here to Demonstrate we’re hoping not only to demonstrate that sweet potato is a fantastic crop for the area, but we’re also with our slip production we’re actually trying to provide the industry With the necessary tools the the thing that they need to do that so we’re not only are we doing it by demonstration? But we’re also committed to supplying certified growers with certified slips so they can get there if their feet wet with sweet potato production You
