Corn Has Diverse Uses and Can Be Transformed Into Varied Products
Maize Based Products Compiled and Edited by Dr Shruti Sethi, Principal Scientist & Dr. S. K. Jha, Principal Scientist & Professor Division of Food Science and Postharvest Technology ICAR-Indian Agricultural Research Institute, Pusa New Delhi 110012 Maize is also known as Corn or Makka in Hindi. It is one of the most versatile crops having adaptability under varied agro-climatic conditions. Globally, it is known as queen of cereals due to its highest genetic yield potential among the cereals. In India, Maize is grown throughout the year. It is predominantly a kharif crop with 85 per cent of the area under cultivation in the season. The United States of America (USA) is the largest producer of maize contributing about 36% of the total production. Production of maize ranks third in the country after rice and wheat. About 26 million tonnes corn was produced in 2016-17 from 9.6 Mha area. The country exported 3,70,066.11 MT of maize to the world for the worth of Rs. 1,019.29 crores/ 142.76 USD Millions in 2019-20. Major export destinations included Nepal, Bangladesh Pr, Myanmar, Pakistan Ir, Bhutan The corn kernel has highest energy density (365 kcal/100 g) among the cereals and also contains vitamins namely, vitamin B1 (thiamine), B2 (niacin), B3 (riboflavin), B5 (pantothenic acid) and B6. Although maize kernels contain many macro and micronutrients necessary for human metabolic needs, normal corn is inherently deficient in two essential amino acids, viz lysine and tryptophan. Maize is staple food for human being and quality feed for animals. -
Different Types of Corn There a Various Types of Corn and They All Have Different Purposes and Distinguished Traits
Different Types of Corn There a various types of corn and they all have different purposes and distinguished traits. Read about the 5 different types of corn and write a 5 paragraph essay on what type of corn you would want to grow. Make sure you do your research! Dent Corn: This type of corn is often used for livestock feeds, industrial products, and as well as used to make processed foods. Another name for dent corn is “Field Corn”. This type of corn is mostly grown in the United States. This corn is a mix of hard and soft starches that become indented when the corn dries out. Flint Corn: Also known as “Indian Corn” is very similar to Dent Corn. They have primarily the same purpose as dent corn, but in the United States its main purpose is decoration. Flint Corn is primarily grown in Central and South America. It has a hard outer shell and the kernels are a variety of colors from red to white. Popcorn: Popcorn is a type of Flint Corn, although it has it has different size, shape, starch level, and moisture content. It has a soft starchy center surrounded by a very hard exterior shell. When popcorn is heated, the natural moisture inside the shell turns into steam and builds up enough pressure until it explodes. Sweet Corn: Also known as “corn on the cob”. This type of corn you will find at your summer BBQ’s and you love to enjoy it with a burger on a hot summer day. This type of corn can be canned or frozen for future consumption. -

Who Doesn't Love Fresh Corn on the Cob in the Summer?
Corn Ahh - who doesn’t love fresh corn on the cob in the summer? It is so good, and so good for you! It not only provides the necessary calories for daily metabolism, but is a rich source of vitamins A, B, E and many minerals. Its high fiber content ensures that it plays a role in prevention of digestive ailments. Growing info: We're expanding our sweet corn production this year by popular demand. The issue with corn, is it takes a lot of space. You can get about 100 ears from every 100 row-feet of planting. When a share consists of 8 ears of corn, this is 8 feet for one share! We plant corn in succession starting in mid May. This will give us a constant supply through summer. Common Problems: Corn ear worms are the TIPS: major pest we deal with in corn. They are tiny little worms that crawl into the tip of the ear and Short-term Storage: Corn converts it's start eating. By the time they get an inch down sugars into starch soon after peak the tip of the ear, they will have grown to a large ripeness, so best to eat it soon. and ugly size. We prevent ear worm by injecting Otherwise, store in a very cold a small amount of vegetable oil into the tips refrigerator. before the worms have a chance of crawling in. Long-term Storage: Cut kernels off the cobs and freeze. You’ll probaby see mostly white corn in 2011.

Zimmerer 1 ABSTRACT. I examined agrobiodiversity in smallholder cultural landscapes with the goal of offering new insights into management and policy options for the resilience-based in situ conservation and social-ecological sustainability of local, food-producing crop types, i.e., landraces. I built a general, integrative approach to focus on both land use and livelihood functions of crop landraces in the context of nontraditional, migration-related livelihoods amid global change. The research involved a multimethod, case-study design focused on a cultural landscape of maize, i.e., corn, growing in the Andes of central Bolivia, which is a global hot spot for this crop’s agrobiodiversity. Central questions included the following: (1) What are major agroecological functions and food-related services of the agrobiodiversity of Andean maize landraces, and how are they related to cultural landscapes and associated knowledge systems? (2) What are new migration-related livelihood groups, and how are their dynamic livelihoods propelled through global change, in particular international and national migration, linked to the use and cultural landscapes of agrobiodiversity? (3) What are management and policy options derived from the previous questions? Combined social-ecological services as both cultivation and food resources are found to function in relation to the cultural landscape. -
Integrated Control of Seed Maturation and Iermination Programs by Activator
Downloaded from genesdev.cshlp.org on September 25, 2021 - Published by Cold Spring Harbor Laboratory Press Integrated control of seed maturation and iermination programs by activator and@ repressor• functions of Viviparous-1 ot maize Ute ~oecker,'Indra K. Vasil, and Donald R. ~c~arty~ Plant Molecular and Cellular Biology Program, Department of Horticultural Sciences, University of Florida, Gainesville, Florida 3261 1 USA The Viviparous-1 (VP1) transcriptional activator of maize is required for abscisic acid induction of maturation-specific genes late in seed development leading to acquisition of desiccation tolerance and arrest in embryo growth. Here, we show that VP1 also inhibits induction of the germination-specific a-amylase genes in aleurone cells of the developing seed and thereby appears to be involved in preventing precocious hydrolyzation of storage compounds accumulating in the endosperm. In developing seeds of the somatically instable vpl-m2mutant, hydrolase activity was derepressed specifically in endosperm sectors underlying vpl mutant aleurone. A barley a-amylase promoter-GUS reporter construct (Amy-GUS) was induced in developing vpl mutant aleurone cells but not in wild-type aleurone cells. Moreover, transient expression of recombinant VP1 in vpl mutant aleurone cells strongly inhibited expression of Amy-GUS and thus effectively complemented this aspect of the mutant phenotype. VP1 specifically repressed induction of Amy-GUS by the hormone gibberellic acid in aleurone of germinating barley seeds. Deletion of the acidic transcriptional activation domain of VP1 did not affect the inhibitory activity, indicating that VP1 has a discrete repressor function. Hence, physically combining activator and repressor functions in one protein may provide a mechanism to integrate the control of two normally consecutive developmental programs, seed maturation and seed germination. -
The Archaeology of Maize
chapter 1 The Archaeology of Maize the domesticators domesticated The story of maize begins at least 9,000 years ago in southwestern Mex- ico as small groups of nomadic people found themselves attracted to stands of a rather tall, bushy tropical grass now known as teosinte (fi gure 1.1). We don’t know what name these early indigenous Mexi- cans had for teosinte, but by the time of the Spanish Conquest there were many names for it, including cincocopi, acecintle, atzitzintle.1 Today evidence of these fi rst farmers and the teosinte plants they har- vested is almost invisible—but we can see some traces left behind by the early descendants of both the plants and the people. For example, pho- tographs of the tiny maize cobs, classifi ed as Zea mays ssp. mays, that were found in Guilá Naquitz cave, Oaxaca, by Kent Flannery and his crew in the mid-1960s show parts of the earliest known individual plants that are descended from an ancestral teosinte plant (fi gures 1.2 and 1.3).2 In order for these cobs, which are directly dated to 6,230 cal BP,3 to have existed, not only did the ancient Oaxaqueños living near Guilá Naquitz cave have to have planted individual seeds, but their ancestors and neighbors also had to have planted and harvested teosinte seeds for hundreds of previous generations. We do not know if these particular early Oaxacan maize plants themselves had descendants. After all, their seeds could have been com- pletely consumed by people or animals and not gone on to propagate 17 BBlakelake - 99780520276871.indd780520276871.indd 1717 005/06/155/06/15 99:06:06 PPMM figure 1.1. -
