AFES Circular 80

To remain competitive, commercial vegetable producers require updated information on the performance of new vegetable varieties under the soil and climatic conditions of southcentral Alaska. Variety trials provide the opportunity to evaluate potentially adapted plant material. Although many varieties are developed in environments considerably different from that of southcentral Alaska, some may prove to be useful to commercial growers in Alaska. The information on new varieties must be collected over several growing seasons to provide sufficient confidence in the observed performance. Additionally, each year of the performance trials, new varieties are grown with traditional or standard varieties which are used to compare the quality of the new varieties. Commercial production of new varieties should be considered after several years of variety trial work with initial plantings on a small production scale.Introduction -- Overview -- Seed Source List -- Weather Summary -- Broccoli -- Cabbage -- Carrots -- Lettuce -- Potatoe

Non-GMO Corn Silage Variety Trial

In 2018, the University of Vermont Extension Northwest Crops and Soils Program evaluated yield and quality of 12 non-GMO corn silage varieties at Bridgeman View Farm in Franklin, VT. A non-GMO milk market has prompted some dairy farmers to start growing corn silage that has not been genetically modified. Conventional farmers have countless corn silage varieties available supported by performance data and trait information. To successfully convert to growing non-GMO corn, farmers are looking for more information on non-GMO varieties that are available and perform well in our region. While the information presented can begin to describe the yield and quality performance of these non-GMO corn silage varieties in this region, it is important to note that the data represent results from only one season and one location

On the hypersurface orbital varieties of sl(N,C)

We study the structure of hypersurface orbital varieties of sl(N,C) (those that are hypersurfaces in the nilradical of some parabolic subalgebra) and how information about this structure is encoded in the standard Young tableau associated to it by the Robinson-Schensted algorithm. We present a conjecture for the exact form of the unique non-linear defining equations of hypersurface orbital varieties and proofs of the conjecture in certain cases.Comment: 17 page

Varieties of uniserial representations IV. Kinship to geometric quotients

Let $\Lambda$ be a finite dimensional algebra over an algebraically closed field, and ${\Bbb S}$ a finite sequence of simple left $\Lambda$-modules. In [6, 9], quasiprojective algebraic varieties with accessible affine open covers were introduced, for use in classifying the uniserial representations of $\Lambda$ having sequence ${\Bbb S}$ of consecutive composition factors. Our principal objectives here are threefold: One is to prove these varieties to be `good approximations' -- in a sense to be made precise -- to geometric quotients of the classical varieties $\operatorname{Mod-Uni}({\Bbb S})$ parametrizing the pertinent uniserial representations, modulo the usual conjugation action of the general linear group. To some extent, this fills the information gap left open by the frequent non-existence of such quotients. A second goal is that of facilitating the transfer of information among the `host' varieties into which the considered uniserial varieties can be embedded. These tools are then applied towards the third objective, concerning the existence of geometric quotients: We prove that $\operatorname{Mod-Uni}({\Bbb S})$ has a geometric quotient by the $GL$-action precisely when the uniserial variety has a geometric quotient modulo a certain natural algebraic group action, in which case the two quotients coincide. Our main results are exploited in a representation-theoretic context: Among other consequences, they yield a geometric characterization of the algebras of finite uniserial type which supplements existing descriptions, but is cleaner and more readily checkable
