Plant growth promoting endophytic bacteria, which can fix nitrogen, plays a vital role in plant growth promotion. Previous authors have evaluated the effect of Gluconacetobacter diazotrophicus Pal5 inoculation on plants subjected to different sources of abiotic stress on an individual basis. The present study aimed to appraise the effect of G. diazotrophicus inoculation on the amelioration of the individual and combined effects of drought and nitrogen stress in maize plants (Zea mays L.). A pot experiment was conducted whereby treatments consisted of maize plants cultivated under drought stress, in soil with a low nitrogen concentration and these two stress sources combined, with and without G. diazotrophicus seed inoculation. The inoculated plants showed increased plant biomass, chlorophyll content, plant nitrogen uptake, and water use efficiency. A general increase in copy numbers of G. diazotrophicus, based on 16S rRNA gene quantification, was detected under combined moderate stress, in addition to an increase in the abundance of genes involved in N fixation (nifH). Endophytic colonization of bacteria was negatively affected by severe stress treatments. Overall, G. diazotrophicus Pal5 can be considered as an effective tool to increase maize crop production under drought conditions with low application of nitrogen fertilizer.

Early Agricultural Period

Metric analyses of recently excavated maize (Zea mays, L.) cupules and cob fragments from Early Agricultural period (2000 B. C.-A.D. 50) sites in southern Arizona indicate that early maize cultivars produced small cobs with small cupules. Although it is risky to generalize about the yield potential of a plant that may have no compelling modern analogues, this work provides further support for the claim that ancient Tucson Basin maize plants provided relatively low yields as compared with more recent varieties.

Planting Season

An Implemented pot experiment  has been conducted in Al-Qadisiyah city - sadder AL- Yusufiya - District 9 in Spring planting season 2016 to study the effect of the overlap between the mineral , organic and bio fertilization in some  growth indicators to maize crop (Zea mays) in Silt Loam texture soils with factorial experiement according to completely randomize  design (Complete random design) and with  three replicates. The expenneit has been done by adding  mineral fertilizers (240 kg N. ha-1 and 80 kg P. ha-1 and 120 kg K. ha-1) three levels (0, 50% and 100%) respectively; and two levels of organic fertilizer (0 and 10 Mg. ha-1) respectively; and two levels of bio-fertilizer (0 and 2 ml. L-1) respectively to the irrigation water. The addition of mineral , organic and bio fertilizers has a significant effecct on the dry matter amount  and the treatment (M2O1B1) is given the highest average of  the dry matter,which reaches to 57.27 g.pot-1 as compared with the control treatment (M0O0B0), reacches to 20.46 g.pot-1 and the increasing percentage reach to 179.91%. There are no significant differences between (M1O1B1) and (M2O1B1). The triple overlap among the metal and organic fertilizers and bio has a significant effect on increasing the percentages of N, P and K in maize plants%, the treatment (M2O1B1) has achieved the highest average of 3.67% N and 0.49% P and 2.19% K respectively, compared with the treatment control (M0O0B0) 2.21% N and 0.23% P and 1.33% K sequentially with  increasing which presentage reached  to  66.06 N% and 113.04 P% and 64.66 K%. There are no significant differences between the treatments (M1O1B1) and (M2O1B1).

The efficiency of inorganic fertilizers can also be done by using mycorrhizal biofertilizers. Efforts to increase corn growth need to be done by using inorganic fertilizers and biological fertilizers. This study aims to determine the effect of urea and mycorrhizae doses on the growth of maize (Zea mays. L). The research was conducted in Gejugan Village, Andong District, Boyolali Regency, an altitude of 154 m above sea level with grumusol soil type. This study used a completely randomized block design (RAKL) with two treatment factors, namely the first factor urea fertilizer dosage consisting of 4 levels, namely N0 = 0 kg / ha, N1 = 100 kg / ha, N2 = 200 kg / ha, N3 = 300 kg. / ha, and mycorrhizae consists of 3 levels, namely M0 = 0 g / plant, M1 = 5 g / plant, M2 = 10 g / plant. with 3 repetitions. The results of this study indicated that the dose of urea fertilizer affected the growth of maize, while the mycorrhizal dose did not affect the growth of maize except for the length of the plant roots. The effect of urea dose interaction with mycorrhizae only affected the root length growth of maize. The best growth of maize plants after being given a dose of urea as much as 100 kg/da and mycorrhizal biofertilizer 10 g / plant with the longest roots (40.44 cm)

Corn plants (Zea mays L.) are one of the second staple food plants after rice plants in Indonesia. Some people in Indonesia consume corn as a staple food. Given the importance of corn crop commodities, as one of the staple foods. So there needs to be an effort to increase the growth and production of corn plants. One such effort is the application of bokashi and varieties. This research was conducted in Kranji Village, Paciran District, Lamongan Regency. With the altitude of ± 5 meters above sea level. The time of the study was conducted from March to June 2019. This study uses Factorial Randomized Block Design (RBD), which consists of two factors, namely: bokashi and varieties. Each factor consists of 3 levels that are repeated 3 times, namely: the first factor, bokashi consists of 3 levels, namely without bokashi, bokashi cow cage, bokashi chicken coop. The second factor, the variety consisted of 3 levels namely BISI 18, NK7328 SUMO, and BISI 2. Observation of growth and production of maize plants includes vegetative phase (plant height and number of leaves) and generative phase (ear length, ear diameter, weight of peel cob ear off harvest, weight of peel cob off harvest per hectare and weight of 1000 seeds). The results showed the interaction between the treatment of bokashi and varieties on the height of maize plants and the treatment of NK7328 SUMO varieties had a good effect on all parameters of observation.

The utilization of low-quality water or slightly saline water in sodic-saline soil is a major global conundrum that severely impacts agricultural productivity and sustainability, particularly in arid and semiarid regions with limited freshwater resources. Herein, we proposed an integrated amendment strategy for sodic-saline soil using biochar and/or plant growth-promoting rhizobacteria (PGPR; Azotobacter chroococcum SARS 10 and Pseudomonas koreensis MG209738) to alleviate the adverse impacts of saline water on the growth, physiology, and productivity of maize (Zea mays L.), as well as the soil properties and nutrient uptake during two successive seasons (2018 and 2019). Our field experiments revealed that the combined application of PGPR and biochar (PGPR + biochar) significantly improved the soil ecosystem and physicochemical properties and K+, Ca2+, and Mg2+ contents but reduced the soil exchangeable sodium percentage and Na+ content. Likewise, it significantly increased the activity of soil urease (158.14 ± 2.37 and 165.51 ± 3.05 mg NH4+ g−1 dry soil d−1) and dehydrogenase (117.89 ± 1.86 and 121.44 ± 1.00 mg TPF g−1 dry soil d−1) in 2018 and 2019, respectively, upon irrigation with saline water compared with non-treated control. PGPR + biochar supplementation mitigated the hazardous impacts of saline water on maize plants grown in sodic-saline soil better than biochar or PGPR individually (PGPR + biochar > biochar > PGPR). The highest values of leaf area index, total chlorophyll, carotenoids, total soluble sugar (TSS), relative water content, K+ and K+/Na+ of maize plants corresponded to PGPR + biochar treatment. These findings could be guidelines for cultivating not only maize but other cereal crops particularly in salt-affected soil and sodic-saline soil.
