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)
