The quest to broaden the narrow range of feed ingredients available to pig producers has prompted research on the use of low cost, unconventional feedstuffs, which are typically fibrous and abundant. Maize cobs, a by-product of a major cereal grown worldwide, have potential to be used as a pig feed ingredient. Presently, maize cobs are either dumped or burnt for fuel. The major challenge in usi...

OLORLESS pericarp and cob is one of the least frequent mutant phenotypes C among the offspring of maize plants carrying the somatically unstable variegated pericarp allele, PV. BRAWN (1956) , for example, found only eight mutations to colorless pericarp and cob in contrast to 125 to red pericarp and cob(P") among 4575 offspring from the mating homozygous variegated times standard colorless (P""...

The P-rr allele of the maize P gene regulates the synthesis of pigments derived from flavan-4-ol in the pericarp, cob glumes and other floral organs. We characterized 21 P alleles derived by intragenic transposition of Ac from three known positions. Ac transpositions can occur in either direction in the P gene, and with no apparent minimum distance: in one case Ac transposed just 6 bp from its ...

The maize P1-rr gene encodes a Myb-homologous transcription factor that regulates the synthesis of red flavonoid pigments. Maize plants transformed with segments of the P1-rr promoter driving a GUS reporter gene exhibit significant variation in transgene expression, both between independent transformation events and among sibling plants derived from a single event. Interestingly, variability in...

Vitamin A deficiency (VAD) is a major public health problem in many developing countries. Orange maize is preferred as green maize and consumed roasted on the cob, especially in Nigeria. This research work was to evaluate the effects of harvest time and husk on the carotenoid contents and sensory properties of roasted orange maize hybrids. The results showed that husk (roasting forms) and harve...

The evaluation of the combinational ability maize I-lines was carried out on basis “the number grains cob”. This parameter is one significant components structure plant productivity and harvest directly dependent grain rows in a cob row. quantitative manifestation this trait significantly influenced by environmental conditions. A negative correlation studied with seed size revealed. Growing con...

Maize is the most important crop in Mexico, being central to diets of consumers, particularly smallholders, and an undetermined amount allocated as straw, green fodder, and, a lesser extent, silage for animal feed. Nitrogen fertilizer considered one factors affecting growth, grain yield, maize biomass production. In this context, main objective study was evaluate effects different levels nitrog...

A study was conducted at Bunda College during the 2003/04 crop season to assess the effect of fertilizer application practices on performance of maize with emphasis on improving the efficiency of using urea as a top dressing fertilizer The treatments were laid out as a split-plot in a randomized complete block design (RCBD) with maize varieties as main plots and fertilizer application practices...
