Impact of Macronutrients and Micronutrients on Soil Health Nutrients Concentration and Uptake by Maize (Zea mays L)

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.

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.

The Impact

We conducted an experiment with two maize hybrids (Zea mays L.) to examine the effect of interplant root competition on root growth and to evaluate the impact to total plant performance. Two maize hybrids (Jinhai 5 and Denghai 3719) were grown either with no root competition in their own plot (owners) or as individuals sharing twice the space and nutrients (sharers). Plants were sampled every other week after pollination to track changes in root and shoot biomass. The carbohydrate allocation was smaller in the roots of sharers compared with owners at the pro-phase of grain filling and shoot accumulation was slightly accelerated during this period. However, at the lag phase, the accumulation rate in the shoots of individual plants was distinctly lower than in owners, as a result of earlier root senescence. Overall, shoot mass was reduced by 8% in sharers of both hybrids, while they showed a similar root to shoot ratio compared with the owners. Although the “sharing” treatment was confounded by larger soil spaces, the effects of larger soil volume and interplant root competition were different, and demonstrate that interplant root competition has an inhibitory effect on roots. Maize plants displayed an overcrowding effect (or an escape strategy) by allocating more carbohydrate to the shoots at the expense of the roots when faced with interplant root competition.Key words: Overcrowding effect, interplant root competition, maize (zea mays L.), root discrimination

Three-year (2014-2016) field experiment was conducted for evaluation of maize (Zea mays L.) based intercropping system for productivity, profitability, energy budgeting and soil health in Eastern Himalayan region. The treatments consisted of four sole crop viz. maize, soybean, groundnut, cowpea and six intercropping treatments viz. maize + groundnut (1:1), maize + soybean (1:1), maize + cowpea (1:1) and strip cropping of maize + groundnut (4:4), maize + soybean (4:4), maize + cowpea (4:4). The highest maize equivalent yield (10.2 t ha-1) was recorded in maize + groundnut cropping system (1:1) followed by maize + soybean (1:1) with 8.9 t ha-1. The highest SNBC (soil microbial biomass carbon) (66.2 mg g-1) and organic carbon (1.3%) were recorded with the cultivation of cowpea as a sole or intercrop. Strip cropping system, maize + cowpea (4:4) recorded the highest soil available N, P2O5 and K2O kg ha-1, highest energy efficiency (12.53) and energy productivity 955.01 g MJ-1

Agriculture in a water-limited environment is critically important for today and for the future. This research evaluates the impact of deficit irrigation in different planting methods on the physio-morphological traits, grain yield and WUE of maize (Zea mays L.). The experiment was carried out in 2015 and 2016, consisting of three planting methods (i.e., BBF, SNF, and DWF) and four irrigation levels (i.e., I10D: irrigation once in ten days, I40: irrigation at 40% DASM, I50: irrigation at 50% DASM, and I60: irrigation at 60% DASM). The results reveal that varying degrees of water stress due to planting methods and irrigation levels greatly influenced the maize physio-morphological traits and yield attributes. The combined effect of DWF + I50 benefited the maize in terms of higher leaf area, RWC, SPAD values, CGR, and LAD, followed by the SNF method at 60 DAS. As a result, DWF + I50 and SNF + I50 had higher 100 grain weight (30.5 to 31.8 g), cob weight (181.4 to 189.6 g cob−1) and grain yield (35.3% to 36.4%) compared to other treatments. However, the reduction in the number of irrigations (24.0%) under SNF + I50 resulted in a 34% water saving. Thus, under a water-limited situation in semi-arid tropics, the practice of the SNF method + I50 could be an alternative way to explore the physio-morphological benefits in maize.
