Waste cobs from variously processed (premature, uncooked, roasted, cooked salted, cooked unsalted) maize (Zea mays) were used as raw materials to prepare growth agar media for six moulds: Rhizopus nigricans, Aspergillus niger, Trichoderma viride, Alternaria tenuis, Fusarium sp, Penicillium sp. and one yeast: Debaryomyces sp. All the formulated media supported the growth of the microorganisms te...

A field experiment was conducted on maize (Zea mays L.) during rabi (November - February), 2018–19 to study the effect of drip fertigation Nitrogen (N), Potassium(K) and microbial consortium (MC) at Water Technology Centre, College Agriculture, PJTSAU, Rajendranagar, Hyderabad. The laid out in randomized block design replicated thrice. treatments, comprising two fertility levels viz., 75% 100% ...

Key impediments to increased corn yield and quality in the southeastern US coastal plain region are damage by ear-feeding insects and aflatoxin contamination caused by infection of Aspergillus flavus. Key ear-feeding insects are corn earworm, Helicoverpa zea, fall armyworm, Spodoptera frugiperda, maize weevil, Sitophilus zeamais, and brown stink bug, Euschistus servus. In 2006 and 2007, aflatox...

Dry matter (DM) partitioning is function of the solar radiation intercepted by the crop canopy and their plant’s leaf area exposed within the canopy. Row orientation (RO) and Row-spacing (RS) within canopy influenced the leaf size and might be the light use efficiency. We, therefore, studied cob bearing leaf area and leaf-area-profile (LAP) of maize planted at different RO, RS and N-rates (0, 1...

Maize originated under warm, seasonally dry conditions of Mesoamerica, and was by human selection converted from a low-yielding progenitor species into its modern form, with a large rachis (cob) of the female inflorescence bearing up to 1,000 seeds. Maize is a C4 plant and is very efficient in water use. If subjected to water stress, however, especially during the mid-season pollination process...

Siderophore facilitates iron availability in soil, but its assistance in iron transportation to different plant parts is not reported till date. Therefore, it is worthwhile to study the effect of siderophore produced by Pseudomonas for iron acquisition in the presence and absence of iron. To study these effects, two siderophore-producing Pseudomonas aeruginosa strains RSP5 and RSP8 were selecte...

The present investigation for studying correlations and path analysis estimates grain yield contributing characters in maize was carried out at Maize Research Centre Seed Farm, Devihosur eleven characters. Days to 50 per cent tasseling significantly positively correlated with days silking negatively plant height, ear cob length, shelling percentage, hundred weight yield. significant percentage ...

Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...

Tandemly repeated endogenous genes are common in plants, but their transcriptional regulation is not well characterized. In maize, the P1-wr allele of pericarp color1 is composed of multiple copies arranged in a head-to-tail fashion. P1-wr confers a white kernel pericarp and red cob glume pigment phenotype that is stably inherited over generations. To understand the molecular mechanisms that re...
