Hybrid Effects on Canopy Spectral Characteristics, Plant Traits, and Grain Yield written by Steven Robert Paszkiewicz and published by . This book was released on 2001 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a given year within a region, the optimum plant populations for 0.38- and 0.76-m row widths were not different. Row width effects on the R:FR ratio were significant at one sampling date in each year. There was a trend for 0.76-m plots to have a higher R:FR ratio compared to 0.38-m plots across sampling dates. At all sampling dates in 1998 and 1999, the 93 860 plant ha−1 plots had lower R:FR ratio measurements. The erect-leaf hybrid, P3394, had higher R:FR ratio for most sampling dates when compared to the horizontal leaf-type hybrids, P3376 and P3618 in 1998 and 1999. These data suggest that canopy light quality is different for those hybrids that demonstrate upright leaf architecture compared to those with prostrate leaf architecture.

Book Synopsis Response of Leafy Reduced-stature Maize (Zea Mays L.) Hybrids to Plant Population Densities and Planting Patterns in a Short-season Area by : Sultan Hussein Begna
Download or read book Response of Leafy Reduced-stature Maize (Zea Mays L.) Hybrids to Plant Population Densities and Planting Patterns in a Short-season Area written by Sultan Hussein Begna and published by . This book was released on 1996 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The yield of short-season hybrids is lower than long-season hybrids, mainly as a result of the low final leaf area developed by the short-season plants. This is due to the smaller plant stature and smaller leaf number and size of short-season adapted hybrids. In addition, in short-season areas the thermal-time available may be insufficient to mature grain of current maize hybrids. Maize hybrids which accumulate leaf area quickly, mature earlier, yield well and tolerate higher population densities better than the currently available hybrids would be more suitable for production in short-season areas. The "Leafy reduced-stature" maize hybrids, which have only recently been developed, have traits which address these criteria. There has been no previous effort to evaluate the effects of more than two plant population densities or the effects of planting patterns on the yield, yield components and vegetative growth of these hybrids. in 1995, field experiments were conducted at two sites near Montreal to compare the response of leafy reduced-stature (LRS), non-leafy normal stature (NLNS), and non-leafy reduced-stature (NLRS) maize hybrids to plant population densities and planting patterns. LRS maize hybrids showed the most rapid growth of the first ear, and the highest yield per single plant and per hectare at high plant population densities in paired rows. LRS hybrids also had longer grain filling periods, lower grain moisture contents and higher harvest indices than conventional (NLNS) hybrids. Rapid growth of the first ear and a higher harvest index are indications that LRS hybrids should be more tolerant of higher population densities than currently available hybrids. Therefore, LRS hybrids show promise for production in short-season areas at high plant population densities where maize cultivation is not currently economical due to shortness of the growing-season." --

Book Synopsis Plant Population and Row Spacing Influence Maximum Corn Yield by : F. D. Whitaker
Download or read book Plant Population and Row Spacing Influence Maximum Corn Yield written by F. D. Whitaker and published by . This book was released on 1969 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in 1965 and 1966 on a fertile Sharon silt loam near Elsberry. Missouri, to determine the maximum yield response of corn for different levels of plant population and now widths, using two hybrids. Adequate fertilizer and irrigation were applied as needed to limit the study to the above variabels. Analysis of corn leaf and whose-plant samples showed that plant nutrition was nor a variable. Adequate soil water was maintained so that the plants were nor under severe water stress after the seedling stage. Other climatic conditions such as cold, wer periods during the early growing season and above-average temperatures during silking and ear-shoot formation limited the yields to below the maximum potential for this area. It is believed, however, that the differences in yield response to the various treatments are representative. Average grain yields from the Pionner 321 hybrid corn were highest from the 24,000- and 20,000- plants populations and 30-inch row widths. The average yields for the 2 years was 159 bushels per acre both populations.(...).

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).
