The Impact

Bio-activated organic fertilizers (BOZ) were produced by enriching the zinc oxide (ZnO)-orange peel waste composite with Zn solubilizing bacteria (ZSB: Bacillus sp. AZ6) in various formulations (BOZ1 (9:1), BOZ2 (8:2), BOZ3 (7:3) and BOZ4 (6:4)). The produced BOZs, along with ZnO, ZnSO4, ZSB were applied to maize crop (Zea mays L.) under field conditions in two different cropping season and the growth, yield, physiology, plant Zn contents and quality of maize were investigated. Results revealed significant variation in the aforementioned parameters with the applied amendments. The BOZ4 performed outclass by exhibiting the highest plant growth, yield, physiology, Zn contents, and quality. On average, an increase of 53%, 49%, 19%, 22%, 10%, 4%, and 30% in plant height was noticed with BOZ4 application over control, ZnO, ZnSO4, BOZ1, BOZ2, BOZ3, and ZSB, respectively. BOZ4 enhanced the dry shoot-biomass 46% than control. Likewise, the photosynthetic rate, transpiration rate, stomatal conductance, chlorophyll contents, carotenoids, and carbonic anhydrase activity were increased by 47%, 42%, 45%, 57%, 17%, and 44%, respectively, under BOZ4 over control in both cropping seasons. However, BOZ4 reduced the electrolyte leakage by 38% as compared to control in both cropping seasons. BOZ4 increased the Zn contents of grain and shoot by 46% and 52%, respectively, while reduced the phytate contents by 73% as compared to control. Application of BOZ4 revealed highest average fat (4.79%), crude protein (12.86%), dry matter (92.03%), fiber (2.87%), gluten (11.925%) and mineral (1.53%) contents, as compared to control. In general, the impact of cropping seasons on maize growth, yield, physiology, Zn contents, and quality were non-significant (with few exceptions). Thus, bio-activation of ZnO with ZSB could serve as an efficient and economical strategy for boosting up the growth, yield, physiological, and quality parameters of maize under field conditions.

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

Growth Chamber Studies

A comparison of biomass and nitrogen (N) parameters from 23 maize (Zea mays L.) inbreds was conducted between hydroponic culturing during two growth chamber studies and soil in the field for two harvests during 1984. The growth chamber studies and first field harvests were sampled at a similar growth stage (approximately nine-leaf); the second field harvest was at anthesis. Shoot dry matter accumulation was greater under hydroponic than under field conditions at a similar vegetative growth stage. Significant inbred differences for shoot biomass, reduced and total N contents and reduced and total N concentrations were determined for the growth chamber and both field harvests. Correlation coefficients were low and not significant (P < 0.05) between inbred parameters in the growth chamber and in the field. In summary, traits from hydroponic plants were not predictive of those from field plants. However, N parameters and biomass of inbreds harvested in the field at a mid-vegetative stage were predictive of inbred performance at anthesis.Key words: Zea mays L., maize, biomass, nitrogen, field, hydroponic

Aims: One of the alternatives proposed to improve the sustainability and productivity of agricultural systems is the use of organic fertilizers based on arbuscular mycorrhizal fungi. The objective of the study was to evaluate the effectiveness of the native mycorrhizal fungus Rhizophagus intraradices in the field at Ouenou in North Benin for improved maize (Zea mays L.) production. Study Design: The experimental design was a complete random block of three treatments. Mention the design of the study here. Place and Duration of Study: Endomycorrhizal infection was assessed on roots of corn plants at 78 days post-seed. Methodology: Corn variety 2000 SYN EE-W was inoculated with the strain in combination with the mineral fertilizer (NPK) half-dose. Results: Results showed that of the three treatments, the highest heights were observed in plants treated with Rhizophagus intraradices +½ dose of NPK (15:15:15) and urea. The same observations were made with respect to leaf number and leaf area of plants and grain yield. Regarding the endomycorrhizal infection of plants inoculated with Rhizophagus intraradices +½ dose of NPK (15:15:15) and urea, of the three producers, the observation was that the endomycorrhizal infection was elevated to the level of the second producer (P2) which was of the order of (50%) while the mycorrhizal intensity was lower (24.6%) in the same producer. Conclusion: The native mycorrhizal fungus R. intraradices plus the half-dose NPK plus urea, had a positive impact on most of the various parameters.

A glass house study was conducted to evaluate the contribution of indigenous arbuscular mycorrhiza fungi (AMF) in improving maize yield grown on sandy loam of Northern Lombok. The package of organic fertilizers treatments were tested including: without inoculation of mycorrhiza, inoculation mycorrhiza and no added inorganic fertilizers, inoculation of mycorrhiza with cattle manure added, inoculation of mycorrhiza with rock phosphate added and inoculation mycorrhiza with inorganic fertilizers. The treatments were arranged using a Completely Randomized Design with four replications. The results of the study show that the inoculation of AMF significantly increased soil concentration of N, available-P, K and organic-C by 37.39%, 60.79%, 66.66% and 110.15% respectively observed at 60 days after sowing (DAS). The similar trend was also found at 100 DAS, where those nutrients increased by 21.48%, 69%, 43.93% and 37.07%, respectively compared to control. The improving of soil fertility status was also reflected by nutrients uptake (i.e. N, P, K, Ca) as well as growth and yield of maize. N, P, K and Ca uptake increased by 1,608%, 1,121%, 533% and 534%, respectively. Roots and top dry biomass at 60 DAS increased by 718.40% and 337.67%, respectively. The trend increased of the biomass was followed by observation at 100 DAS. Yield components including cobs, grain and weight of 100 grains increased by 313.60%, 411.84% and 137.54%, respectively. In addition, the inoculation of AM with F2 contributed significantly to the spore numbers and root infection.[How to Cite : Astiko W, IR Sastrahidayat, S Djauhari, and A Muhibuddin. 2013.

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.
