Download or read book Growth and Productivity of Winter Maize Zea mays L Under Different Levels of Nitrogen and Plant Population written by Jiban Shrestha and published by Universal-Publishers. This book was released on 2015-09-29 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment was conducted at farmer’s field of Anandapur, Mangalpur VDC-3, Chitwan, Nepal during winter season from September 2006 to February 2007 to study the effects of nitrogen and plant population on maize. Fifteen treatment combinations consisting of five levels of nitrogen: 0, 50, 100, 150 and 200 kg N/ha and three levels of plant population; 55555 plants/ha (60 cm × 30 cm spacing), 66666 plants/ha (60 cm × 25 cm spacing) and 83333 plants/ha (60 cm × 20 cm spacing) were tested in factorial randomized complete block design (RCBD) with 3 replications. “Rampur Composite” variety of maize was planted on sandy silt loam and strongly acidic soil having medium in total nitrogen (0.123%), high in soil available phosphorous (77.56 kg/ha) and low in soil available potassium (23.25 kg/ha). The research findings revealed that each level of nitrogen significantly increased grain yield upto 200 kg N/ha. The grain yield (6514.48 kg/ha) obtained under 200 kg N/ha was significantly higher than that of 0, 50, 100 and 150 kg N/ha. The percent increment in yield due to application of 50, 100, 150 and 200 kg N/ha was to the extent of 62.11, 104.74, 135.68 and 154.74%, respectively over control. Significant effect on grain yield due to different levels of plant population was observed. The grain yield (5113.46 kg/ha) obtained under 66666 plants/ha was statistically at par with that under 83333 plants/ha, but significantly superior over that under 55555 plants/ha. The interaction between different nitrogen levels and plant densities on grain yield showed that the highest grain yield (6925.79 kg/ha) was obtained under treatment of 200 kg N/ha + 66666 plants/ha. The yield attributes namely number of cobs/plant, cob length, cob diameter, number of grain rows/cob and 1000 seed weight significantly increased with increasing N levels and decreasing plant population levels. The number of barren plants/ha decreased with increasing levels of N but increased with increasing levels of plant population. The net return (Rs. 42188.74/ha) and benefit:cost ratio (1.67) obtained under 200 kg N/ha were significantly highest than that obtained under other levels of nitrogen (150, 100, 50 and 0 kg N/ha). The plant population of 66666 plants/ha gave the highest net returns (Rs. 25812.28) which was 10.19 and 49.64% higher than that of 83333 plants/ha and 55555 plants/ha, respectively. The benefit: cost ratio (1.44) obtained under 66666 plants/ha was significantly higher than that of 55555 and 83333 plants/ha. The interaction between different nitrogen levels and plant densities on economics of maize production showed that significantly highest net return (Rs.48606.98) and B:C ratio (1.78) were under treatment of 200 kg N/ha + 66666 plants/ha. The highest grain yield and maximum profit were obtained when maize variety “Rampur Composite” was planted with 200 kg N/ha and plant population level of 66666 plants/ha (60 cm × 25 cm spacing).

Available in PDF, EPUB and Kindle. Book excerpt: This open-access edited book is a collection of 17 chapters, synthesized primarily from the lectures delivered by eminent Indian and international experts during a series of capacity-building programmes organised in India during 2020 and 2021 under the aegis of 'Indo-German Cooperation on Seed Sector Development', a component of the Bilateral Cooperation between the Governments of India and Germany. Seed Science and Technology, a multi-disciplinary subject, is advancing rapidly keeping pace with the development of improved plant varieties and other climate-resilient technologies. Knowledge of the underlying biological processes and application of appropriate technologies for variety maintenance and seed production; quality assurance, testing and enhancement; processing, packaging and storage etc., are important in a seed programme. Chapters presented in the book is a blend of basic seed biology covering seed development, maturation, dormancy, germination, vigour and invigoration, and seed deterioration; variety maintenance and production of genetically pure seed of open-pollinated and hybrid varieties in a few key field crops and vegetables, and fundamentals of seed processing, packaging and storage; and seed quality assurance systems followed in different countries; testing the essential components of seed quality including seed health, application of molecular technologies for precision in testing, and enhancement of seed quality. It concludes by identifying the key areas of future seed research and technology development. The book covers the fundamentals and recent advances of seed science and technology with the latest research information and an exhaustive and updated list of references on different topics. It is expected to benefit the students as well as the scientists, faculty members and seed sector professionals, working in the public and private seed sectors, certification authorities and seed producing agencies in India, and elsewhere.

This book was released on 2018-02-07 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is an important staple crop in Ghana, but maize productivity is low. Other countries with similar agroecological conditions have increased maize productivity by increasing the use of maize hybrids. This paper presents the results of maize trials in northern Ghana, in which hybrids were tested to see if they performed significantly better than the varieties planted by farmers. This paper details the procedures of the maize trials and presents descriptive statistics of the trial results. The trials demonstrated that two foreign hybrids performed consistently better than Obaatanpa, the most widely used variety in the north. The foreign hybrids performed consistently well in all districts and appear to be well-suited for planting in northern Ghana.

Book excerpt: Maize is one of the versatile emerging crops with wider adaptability under varied agro-climatic conditions. Globally, maize is known as queen of cereals because it has the highest genetic yield potential among the cereals. It is cultivated on nearly 150 m/ha in about 160 countries having wider diversity of soil, climate, biodiversity and management practices that contributes 36 % (782 m/t) in the global grain production. The United States of America (USA) is the largest producer of maize contributes nearly 35 % of the total production in the world. It is the driver of the US economy. This book talks about the improvement, production, protection and post harvest technology of the maize crop.

Book excerpt: This book attempts to present a readable format on plant breeding principles and their application, based on the collective experience of the three authors, but with a heavy dependence on the scientific literature. Modem pedagogy recognizes that teaching can occur when students are motivated to learn. Subject matter must be communicated in an interesting, appealing, and understandable fashion. In preparing the text, every effort has been made to translate pertinent plant breeding references into a clear, logical, and comprehensible format for those studying the challenging and dynamic field of plant breeding.
