The invention claimed is: 1. A seed tube, through which individual seeds pass, for an agricultural seeding machine, said seed tube comprising: a side wall having a continuous non-disjoint substantially smooth surface exposed to said seeds and including at least a portion thereof comprised of a substantially transparent material; and a sensor including a transmitter, said transmitter positioned adjacent an outside of said side wall, and operating through said transparent material to detect passage of individual seeds through said seed tube. 2. The seed tube of claim 1, wherein said transparent material is opaque to ambient light and transparent to said transmitter. 3. The seed tube of claim 1, wherein said side wall includes a window comprised of said transparent material, a remainder of said side wall being opaque to ambient light. 4. The seed tube of claim 3, wherein said remainder of said side wall comprises one of an opaque material, a transparent material with opaque tinting, and a transparent material with an opaque coating. 5. The seed tube of claim 1, wherein said side wall includes a sensor mount. 6. The seed tube of claim 5, wherein said sensor mount includes a sensor pocket. 7. The seed tube of claim 6, further including one of a seal and an adhesive between said sensor and said sensor pocket. 8. The seed tube of claim 1, wherein said transparent material comprises a substantially clear plastic material. 9. The seed tube of claim 1, wherein said transparent material comprises one of a plastic material and glass. 10. The seed tube of claim 1, wherein said transmitter comprises a light source. 11. The seed tube of claim 10, wherein said light source comprises an LED. 12. The seed tube of claim 1, wherein said side wall comprises a front wall. 13. The seed tube of claim 1, wherein said side wall includes an outer surface which is textured in an area away from said sensor. 14. A seed tube, through which individual seeds pass, for an agricultural seeding machine, said seed tube comprising a front wall and a rear wall defining a hollow interior therebetween, at least one of said front wall and said rear wall having a continuous non-disjoint substantially smooth surface exposed to said seeds and including at least a portion thereof comprised of a substantially transparent material, and a sensor mount positioned in association with said transparent material on a side opposite said hollow interior to detect passage of individual seeds through said tube. 15. The seed tube of claim 14, wherein at least one of said front wall and said rear wall include a window comprised of said transparent material, a remainder of said front wall and said rear wall being configured opaque. 16. The seed tube of claim 15, wherein said remainder of said front wall and said rear wall comprises one of an opaque material, a transparent material with opaque tinting, and a transparent material with an opaque coating. 17. The seed tube of claim 14, wherein at least one of said front wall and said rear wall includes a sensor mount. 18. The seed tube of claim 14, wherein each of said front wall and said rear wall has an outer surface which is textured in an area away from each said sensor. 19. An agricultural seeding machine, comprising: a seed meter; and a seed tube positioned to receive individual seeds from said seed meter for passage through said seed tube, said seed tube including: a side wall having a continuous non-disjoint substantially smooth surface exposed to said seeds and including at least a portion thereof comprised of a substantially transparent material; and a sensor including a transmitter, said transmitter positioned adjacent an outside of said side wall, and operating through said transparent material to detect passage of individual seeds through said seed tube. 20. The agricultural seeding machine of claim 19, wherein said side wall includes a window comprised of said transparent material, a remainder of said side wall being configured opaque. 21. The agricultural seeding machine of claim 20, wherein said remainder of said side wall comprises one of an opaque material, a transparent material with opaque tinting, and a transparent material with an opaque coating. 22. The agricultural seeding machine of claim 19, wherein said side wall includes a sensor mount. 23. The agricultural seeding machine of claim 22, wherein said sensor mount includes a sensor pocket. 24. The agricultural seeding machine of claim 23, further including one of a seal and an adhesive between said sensor and said sensor pocket. 25. The agricultural seeding machine of claim 19, wherein said side wail has an outer surface which is textured in an area away from said sensor.
