A field experiment was conducted in the agricultural season (2016 - 2017) in one of the fields of college of Agriculture - University of AL-qadisiyah on mays L. Zea to study the interrelated effect of both the acid and Azotobacter and Azospirillum. The experiment was applied according to RCBD design and three replicates. The treatment included 12 treatments resulting from the treatment of Control and Azotobacter , Azospirillum , organic fertilizer, The most important results reached:1. Azotobacter + Azospirillum + organic fertilizer have the superior to the vegetative growth characteristics of mays by giving the highest average (number of leaves, dry weight of leaves, dry weight of root total) (24.67, 17.5 g, 8.17) g respectively, except for treatment (Azospirillum + organic fertilizer) was superior in plant height 92.0 cm.2. Azotobacter + Azospirillum + organic fertilizer has the highest values for the chemical grade of mays in (potassium, calcium, sodium, respectively (0.243, 2.60 and 0.077) %.

Black corn has its advantage compare to regular corn due to the nutrition component. This could lead the increase of demant to this corn variety. The Effect of providing various biochar sources and various manure on the growthand production of Zea mays black maiz L. The study used factorial randomized block design with two factors, namely the provision of various biochar sources which was combined into several organic fertilizer. Parameters observed were plant height, stem diameter, number of leaves, wet production weight/sample using klobot, wet production weight/plot using klobot,wet production weight/sample without klobot, wet production weight/plot without klobot, dru production weigh of pipil/sample, dry weight of production of onehundred grain pipil. The results of the study showed that the effect of giving various biochar of rice husk corn cobs of candlenut shells did not signficantly affect all observation parameters and various manure, namely cows, chickens and goats also did not significantly affect all observed parameters.

The open-pollinated corn (Zea mays L.) cult Gaspé Flint and three hybrids, Guelph GX122, Harrow 691, and Pioneer X306, were selected to examine the effects of photoperiod and temperature on the number of days to tassel initiation. The range of maturity of this material varied from extremely early to subtropical. The experiments, conducted in growth cabinets, examined photoperiods of from 10 to 20 h in 21/2-h increments. Constant day–night temperatures examined were 20, 25, and 30 C. Photoperiod and temperature affected number of days to tassel initiation. The response was not consistent for each genotype. As daylength increased from 10 to 20 h all but the earliest genotype, Gaspé Flint, took longer to reach tassel initiation. The latest hybrid, Pioneer X306, was affected relatively more by photoperiod. The delay in tassel initiation with longer photoperiods was apparent at all temperatures; however, the magnitude of the response was less at the high temperature. With longer photoperiods, there was an increase in the amount of vegetative growth and development prior to tassel initiation. This was apparent from the greater number of emerged leaves, the longer stem length, and the greater plant dry weight at tassel initiation.

One way to improve maize (Zea mays L.) production is through land extension using Andisol land. However, andisol soil has phosphate (P) fixation problem due to the high amorphous material. Hence, the use of organic material in the form of humic acid that has greater affinity to amorphous minerals is recommended to solve the problem. This research was conducted in February-May 2017 at Tri Dharma field of Faculty of Agriculture, Gadjah Mada University. The Andisol land used has a low available P category from Datar, West Java and Wonosobo, Central Java. This research was arranged in a Randomized Complete Block Design (RCBD), consisting of 2 factors. The first factor was maize cultivar (Bisi-2 and Pioneer-35). The second factor was the doses of humic acid, consisting of control treatment (without fertilizer and humic acid), NPK without humic acid, and NPK + humic acid at 5%, 10%, and 15%. The percentage of humic acid given, based on the amount of NPK 16:16:16 fertilizer, was 350 kg ha-1. Fertilization was applied 3 times 100 kg ha-1 on 1 WAP, 150 kg ha-1 at 3 WAP and 100 kg ha-1 at 7 WAP. The results is, humic acid treatment had the same effect with NPK fertilization treatment only and control on P available Andisol soil. Humic acid, also has the same effect with NPK fertilizer treatment in increasing the yield component of 100 seeds weight, dry weight of seeds, harvest index, length of cobs and productivity.

This research was conductedat the experimental field, the Laboratory for Research and Technology Faculty ofAgriculture, University of North Sumatra, Medan from August to November 2016. Thethe design used in this study is a randomized block design factorial using two factors:organic fertilizers (O) with treatment as follows: O0 = Without organic fertilizers,O1 = 100% of doses of organic fertilizer, O2 = 75% of doses of organic fertilizer, O3= 50% of doses of organic fertilizer, O4 = 25% of doses of organic fertilizer.inorganic fertilizer application (A) with treatment as follows: A0 = Withoutinorganic fertilizers, A1 = 100% of doses of inorganic fertilizer recommendations,A2 = 75% of doses of inorganic fertilizer recommendations, A3 = 50% of doses ofinorganic fertilizer recommendations, A4 = 25% of doses of inorganic fertilizerrecommendations. The variables measured were: plant height, shoot dry weight, rootdry weight, dry seed weight. Results showed that 100% Organic fertilizer canincrease growth and yield of corn were higher in soil ultisol. This is indicated bytheir real influence on the growth of plant height ages 8 and 12 WAP, the weight ofdry seed, uptake of N and P, but no significant effect on shoot dry weight, root dryweight and uptake K. Inorganic fertilizer application of 100% can increase growthand yield of corn was higher in soil ultisol. This is indicated by their real influenceon the growth of plant height age 8 WAP, root dry weight and the weight of dry seed,but did not significantly affect plant height age of 12 WAP, shoot dry weight, uptakeof N, P and K. The interaction of the two combination treatments showed significantlyeffect on the weight of dry seed.

A field experiment was conducted during the autumn season of 2018 at agricultural research station in Al- Qurna district (80 km north of Basra center). The aim was to study the effect of spraying different concentrations of humic acid (HA) and silicon on the some growth characteristics of maize (Zea mays L.). The experiment was conducted using Three Concentration of humic acid were used 0, 2 and 4 gm L-1, which took the following symbols H0, H1, and H2 respectively and four concentrations of silicon 0, 1, 2 and 3 mML-1 which took the symbols S0, S1, S2 and S3 respectively. A factorial experiment was used in randomized completely block design with four replicates. Maize seeds cv. Fajir1 were planted at 20/7/2018 in a silty loam soil. The results showed that the concentrations of HA differed significantly in all most of the studied characteristics, plant height, leaf area and ear length with an increase by 11.69, 24.89 and 3.49% respectively as compared to the control treatment (H0). The spraying with silicon showed a significant effect. Moreover, the concentration of S3 gave the highest values for plant height, stem diameter, leaf area and ear length. The interaction between HA and silicon showed a significant effect on some of the studied characteristics, the combination of S3×H2 produced the highest values of plant high (174.42 cm) and leaf area (7390.65 cm2).

The response of rate and duration of kernel dry matter accumulation to temperatures in the range 10–25 °C was studied for two maize (Zea mays L.) hybrids grown under controlled-environment conditions. Kernel growth rates during the period of linear kernel growth increased linearly with temperature (b = 0.3 mg kernel−1 d−1 °C−1). Kernel dry weight at physiological maturity varied little among temperature treatments because the increase in kernel growth rate with increase in temperature was associated with a decline in the duration of kernel growth proportional to the increase in kernel growth rate.Key words: Zea mays L, period of linear kernel dry matter accumulation, controlled-environment conditions, kernel growth rate
