4 J ~ 4"t An improved system for growing plants is pro- vided which includes an envelope having a closable seam along at least one edge and having sheets of porous flexible material which carry a number of dry nutrient packs supported within the envelope. Plants may be inserted at intervals along the open seam and the seam partly closed by clamping means around the stems of each of the plants. In one embodiment of the invention a vertical configuration is employed while in other embodiments, a horizontal configuration is em- ployed.

This invention relates to a method for biological control of multiple plant weeds, sicklepod, showy crotalaria, and coffee senna. The control is accomplished using a specific host strain of the fungus Alternaria cassiac to produce typical le- sions in and kill the multiple weeds. Alteruaria cassiac is on deposit with the USDA-SEA-AR Southern Weed Science Laboratory in Stuneville, Miss/ss/ppi; the Mycological Ser- v/ces, Botany Department, Un/versity of Mas- sachusetts, Amherst; and with the Agricultural Research Culture Collection (NRRC), Peoria, Illinois and assigned the £12553.

Two powdered protein products are produced from animal raw material of varying composi- tion, in particular offal from bacon factories and cattle slaughterhouses. The offal is heat treated and separated mechanically into a fluid phase and a solid phase, which is powder-dried with subsequent removal of bone pieces to obtain the first protein powder. The fluid phase is separated into a sludge which is returned into the process, into a fat phase-which is processed into technical fat and into a size phase which is spray-dried separately in order to obtain the second protein powder. The powders produced are free flowing without any lumping tendency. The first powder has a protein content which corresponds to the content of conventionally produced meat-bone meal, whereas the second powder has a high pro- tein content and has gluing properties and may therefore be used as a giuing agent or as a protein supplement for fodder.

A lymphoblastoid cell line of turkey origin designated as MDTC-RP-19 and deposited un- der the ATCC Accession No. CRL-8135 has been found useful for the in vitro propagation of hcmorrhag/c enteritis virus (HEV). Cocultiva- tion of the apathoganic strain of HEV with the cell line is useful in the production of a vaccine for protecting fowl against virulent HEV.
