Term Field

A short-term field and laboratory experiment was conducted to assess the impact of four traditional tillage methods on the physical, chemical and biochemical properties of a sandy clay loam alfisol under maize (Zea mays L.) cultivation following a fallow period of five years. Treatments included slash only (SO), slash +burn (SB), slash+ ridge (SR) and herbicide (glyphosate) application (HA) at the recommended rate of 2 L/ha-1. Results from the statistical analysis of data from this study showed inconsistent trends of tillage treatments on soil physical properties. However, slash +burn (SB) tillage significantly (p < 0.05) enhanced chemical properties such as the soil pH, available P, exchangeable K+, Ca2+, and Mg2+ compared to their respective values before treatment application in the two years under study. Amongst the treatments, slash + burn (SB) tillage further exerted the most significant (P ≤ 0.05) effect on urease, L-asparaginase, L-glutaminase, dehydrogenase, acid and alkaline phosphatase activities, but recorded the least values for amidase and β-glucosidase activities in soil. Results from this study therefore, suggest that SB tillage treatment was beneficial to the soil environment as it has proven to be more promising and effective for enhancing the selected soil quality indicators on the soil type due to quick mineralization and release of bound nutrients present in the soil and litter.

The Impact

At the SHUATS Department of Soil Science and Agricultural Chemistry Research Farm, an experiment was conducted with the goal of determining the impact of application of macro and micronutrients, on soil health nutrients concentration and uptake by maize (Zea mays L). The experiment was put up based on this over a two-year period, beginning with the 2017 and 2018 cropping periods. Crbd was used as the experimental technique and it was replicated thrice with the following treatments combinations, NPK @ 50 and 100kgha -1, while for the micronutrients (Boron, Zinc and Copper) three levels of combination were used 0.3, 6 and 9kgha-1. The research project's findings showed all the determinants of soil health like soil reaction organic matter among others are at levels suitable for nutrients actions and plant growth, while plant parameters like maize cob diameter, dry matter, and nutrients concentrations in maize tissues have greatly improved. NPK @100kgha-1, Copper, Zinc, and Boron @ 9kgha-1 were the best treatment combinations with the best results. The above combinations of treatments will be suitable for the soils of that location based on the results of these studies.

Routine Handling

Maize (Zea mays L. cv. XL45) plants were grown from seed in controlled-environment rooms. Twice-daily weighings of the plants and containers for 7 days reduced height, and removing plants from the rooms for two 20-min periods daily for 7 days gave significant reductions in stem and leaf dry weights and total leaf area. Transpiration rates were not affected by either of these treatments. Short-term removal from the rooms (up to 10 min daily) produced no significant reductions in plant characteristics. Measuring leaf lengths daily for 10 days resulted in significant reductions in stem dry weight and plant height. It is suggested that control plants should always be subjected to the same degree of handling as treated plants.

Short Term Effects

The effect of 10<sup>-2</sup>-10<sup>-6</sup> M Mn<sup>+2</sup> on the growth and acidification of the incubation medium by <em>Zea mays</em> L. coleoptile segments was studied. It is shown that 10<sup>-5</sup>M manganese stimulated growth (in comparison to a control without Mn<sup>+2</sup>) while concentrations from 10<sup>-2</sup> to 10<sup>-4</sup>M clearly inhibited it. It was also found that manganese at the studied concentration range significantly inhibited acidification of the incubation medium. Auxin, at a concentration of 10<sup>-5</sup>M, reversed the inhibitory effect of Mn<sup>+2</sup> (with the exception of 10<sup>-2</sup>M) on the growth and acidification of the incubation medium by <em>Zea mays</em> L. coleoptile segments.

The Impact

Spring maize (Zea mays L.) is a thermophilic C4 crop which is sensitive to climate change. This paper provides a detailed assessment of the effect of climate change on the crop from a new perspective, by predicting the probability of the potential distribution of spring maize across China. The affected area of spring maize suitability was identified, and then the affected area was subdivided into the improved area and the deteriorated area. Our results confirmed that there was a detrimental consequence for spring maize suitability under observed climate change from 1961–1990 to 1981–2010. However, our results revealed that warming scenarios of 1.5 °C and 2 °C were helpful for the suitable area expansion of spring maize. The affected area was smaller under warming scenarios than under historical climate change, revealing that temperature rise alone was not enough to trigger a “tipping point” (a threshold value after which abrupt shifts occur) for spring maize, even if warming is 2 °C above the level of 1961–1990. Our results not only benefit China in the design of mitigation and adaptation strategies, but also provide a theoretical judgement that the impact of global warming on the crop ecosystem is not serious if other climate factors remain unchanged.
