The Effects of Tillage and Irrigation on Sweet Corn (Zea Mays L.) Development, Yield, and Water Use

Category : Sweet corn

Pages : 136
Book Description
'Jubilee' sweet corn was grown under conventional tillage and strip tillage in 1982 and under conventional tillage, strip tillage and no-till culture in 1983. Effects on soil temperature, stand establishment, plant development parameters, overall yield, yield components, and water use efficiency were measured. In 1982, conventional tillage appeared to have a higher yield than strip tillage but the difference was not significant. The 1983 conventional tillage treatment was significantly higher than the strip tillage treatment yield, which in turn was greater than for that of no-till. Yield parameters in both seasons indicated the strip tillage resulted in fewer and less mature ears at harvest than did the conventional tillage treatment. The yield parameters from the no-till treatment in 1983 were also lower than those of the conventional tillage treatment. Depression in plant development parameters and resulting yield appeared to be strongly related to lower soil temperature the first 30 days after planting, which was always highest in the conventional tillage treatment unless the soil was recently hydrated. The cropwater production functions for yield vs. evapotranspiration were different in scale but similar in slope for the three tillage treatments in 1983. The strip tillage and no-till methods did not use water as efficiently as the conventional tillage method to produce the same unit of yield.

Drought Stress in Maize (Zea mays L.)

Pages : 79
Book Description
This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

The Effects of Planting Date, Nitrogen and Boron Application on Mineral Element Concentration, Yield, Dry Weight and Fresh Weight of Sweet Corn

Book Description
The effects of planting date on mineral element concentration in sweet corn (Zea mays L. cv. Jubilee) at six developmental stages and on yield were investigated. Planting dates were chosen to correspond to early, mid-season, and late commercial plantings. Two nitrogen rates were applied since nitrogen is more often limiting than any other nutrient for sweet corn grown in Western Oregon. Boron was also applied since it has been shown to be limiting in many other crops grown in the Willamette Valley. Planting date significantly affected N, P, K, Ca, Mg, Mn, Fe, Cu, B, and Zn concentration in the whole plants during the vegetative growth stages and in the ear leaves during the stages between tasseling and harvest. During the early stage of growth, N, P, K, Ca, Mg, B, and Zn tended to be higher in the early planted corn plants, while later in the development of corn the effects of planting date were more variable. Planting date also affected the fresh and dry weight of whole plants; the later planting produced more dry weight than the earlier two plantings, while the early planted corn produced more fresh weight at harvest than the later two plantings. Consequently, when analyzing sweet corn for nutritional status, date of planting should be considered when interpreting the plant analysis data. The application of B had no effect on yield, fresh weight or dry weight and only increased B concentration at the first developmental stage. The additional application of N, did not significantly increase yield for the late planted corn, but did for early planted corn. N concentration, as well as Mg, Mn, Cu, and Zn concentrations increased with the higher rate of N fertilizer applied (125 kg/ha). Fresh weight and dry weight were both higher in the plants receiving the higher rate of N, with the difference becoming greater as the plants matured.
