Double Cross Hybrids Performance for Quality and Earliness Traits in some Egyptian Cotton Genotypes [PDF]

open access: yesJournal of Plant Production, 2021
Genotypes used in present investigation consisted of five cotton varieties belong to (Gossypium barbadense, L.). Three of these varieties were long staple, BBB (big black boll) (P1), Australian (P2) and G97 (P3) while the other two varieties were extra ...

Constructive Canonicity of Inductive Inequalities [PDF]

open access: yesLogical Methods in Computer Science, 2020
We prove the canonicity of inductive inequalities in a constructive meta-theory, for classes of logics algebraically captured by varieties of normal and regular lattice expansions.

Varieties of K-lattices

open access: yesFuzzy Sets and Systems, 2022
In this paper we deal with varieties of commutative residuated lattices that arise from a specific kind of construction: the {\em twist-product} of a lattice. Twist-products were first considered by Kalman in 1958 to deal with order involutions on plain lattices, but the extension of this concept to residuated lattices has attracted some attention ...

Varieties of bounded K-lattices

open access: yesFuzzy Sets and Systems, 2022
In this paper we continue to study varieties of K-lattices, focusing on their bounded versions. These (bounded) commutative residuated lattices arise from a specific kind of construction: the {\em twist-product} of a lattice. Twist-products were first considered by Kalman in 1958 to deal with order involutions on plain lattices, but the extension of ...

Performance, Variance Components, and Acceptability of Pro-vitamin A-Biofortified Sweetpotato in Southern Africa and Implications in Future Breeding

open access: yesFrontiers in Plant Science, 2021
In sub-Saharan Africa (SSA), vitamin A deficiency (VAD) is a major cause of blindness in children under 5 years. Sweetpotato (Ipomea batatas L.) is widely grown in this region, and pro-vitamin A varieties could help to combat such problems.

Varieties of Lattices with Geometric Descriptions [PDF]

open access: yesOrder, 2011
A lattice L is spatial if every element of L is a join of completely join-irreducible elements of L (points), and strongly spatial if it is spatial and the minimal coverings of completely join-irreducible elements are well-behaved. Herrmann, Pickering, and Roddy proved in 1994 that every modular lattice can be embedded, within its variety, into an ...

Bases for certain varieties of completely regular semigroups [PDF]

open access: yes, 2021
summary:Completely regular semigroups equipped with the unary operation of inversion within their maximal subgroups form a variety, denoted by $\mathscr{CR}$. The lattice of subvarieties of $\,\mathscr{CR}$ is denoted by $\mathcal{L}(\mathscr{CR})$.

Nutritional management and maize variety combination effectively control Striga asiatica in southern Africa

open access: yesCABI Agriculture and Bioscience, 2022
Maize (Zea mays L.) is an important staple food crop in sub-Saharan Africa (SSA) and contributes significantly to food security. Due to Striga, maize yield loss is estimated between 20 and 80% forcing some farmers to abandon their land therefore ...

Genetic parameters of agronomic traits and yield components of soybean genotypes in the Colombian Altillanura

open access: yesRevista U.D.C.A Actualidad & Divulgación Científica, 2022
Soybean cultivation expansion in Colombia has generated the need to seek varieties with high genetic merit. A soybean genetic breeding program seeks to generate varieties with competitive and sustainable yields, and high-quality grain adapted to the ...
