Peatland in Indonesia has a potential for maize cultivation, but it has constraints that low of soil pH and of nutrient availability. Use of ameliorants from coastal sediment and salted fish waste was an alternative to improve peatlands productivity and maize yields. Objective of the study was to examine effects of coastal sediment and salted fish waste on growth and yield of maize at three kinds of soil of peatlands of Kubu Raya, West Kalimantan. This research was conducted  in  field  using  Inter-area analysis  design.  The  first  factor  was  combination  of  each ameliorants  which consisted of 5 levels, namely: 1) treatment under farmer custom at the sites (control); 2) coastal sediment of 20 Mg ha-1 + 0.75 Mg of salted fish waste ha-1; 3) coastal sediment of 40 Mg ha-1 + 1.5 Mg of salted fish waste ha-1, 4) coastal sediment of 60 Mg ha-1 + 2.25 Mg of salted fish waste  ha-1. The second factor was soil types which consisted of three levels, namely: Typic Haplohemists, Typic Sulfisaprists and Typic Haplosaprists. Each treatment was repeated 5 times. The results showed that combination of 40 Mg ha-1 of coastal sediment and 1.5 Mg ha-1 of salted fish waste was the best combination for all soil type. It increased plant height (33% - 44%), shoot dry weight (74% - 75%), number of seeds per cob (31% -110%), weight of 100 seeds (58% -71%) and dry grain weight per plant (136 % -160 %) at each soil. The highest yield was found in soil of Typic Haplosaprists (219.54 g), followed by Typic Sulfisaprists (210.72 g) and Typic Haplohemists (208.82 g).Keywords: Coastal sediment, maize, peat soils, salted fish waste [How to Cite: Denah S, BH Sunarminto, D Shiddieq and D Indradewa. 2014.

Volunteer winter wheat (Triticum aestivum L.) is a sporadic weed found in corn (Zea mays L.) fields across southern Ontario. Eight trials were conducted over a 2-yr period (2006 and 2007) at four locations to determine the competitiveness of volunteer winter wheat in corn. A soft red winter wheat cultivar (Pioneer 25R47) was seeded at each location at densities of 0 to 30 seeds m-2 late in the fall, prior to corn planting the following spring. Volunteer wheat competition in corn resulted in reduced emergence of corn leaf collars. Competition with volunteer wheat resulted in a 5% decrease in corn leaf collars present at 21 and 70 d after emergence with volunteer wheat densities of 3.0 and 5.2 plants m-2, respectively. Furthermore, volunteer wheat competition reduced total leaf area, leaf dry weight, shoot dry weight, plant and ear height and yield by 5% with densities of 5.1 to 6.0 plants m-2 compared with the weed-free control. The level of competitiveness was dependent on the density of volunteer wheat.

Abstract This study aims to determine the effect of drought stress and mycorrhizal dose on the growth and yield of maize (Zea mays L.). The research was done in the BPTP Banten Screen House and the Soil and Climate Laboratory of the Faculty of Agriculture, Sultan Ageng Tirtayasa University starts from November 2020 until February 2021. This study used a factorial randomized block design (RBD) consisting of two factors. First factor was drought stress with four levels, namely k1 (100% FC), k2 (80% FC), k3 (60% FC), and k4 (40% FC) and second was the mycorrhizal dose with 3 levels, called m0 (0 g/pot), m1 (10 g/pot), and m2 (20 g/pot). There were 12 treatment combinations that were repeated 3 times in order to obtain 36 experimental units. The results showed that the drought stress treatment had a significant effect on maize plant height at 7 WAP of 174.22 cm, plant dry weight of 86.67 g, root dry weight of 21.67 g, and seed dry weight of 37 g. Drought stress of 40% FC can reduce the growth and yield of maize. The mycorrhizal dose treatment had no significant effect on the growth and yield of maize. The application of mycorrhizal dose of 20 g/pot tends to increase the growth and yield of maize. There was no interaction between drought stress treatment and mycorrhizal dose on growth and yield of maize.

In greenhouse and field trials, gibberellic acid (GA) pipetted directly into the leaf whorls of the extremely early-maturing maize (Zea mays L.) inbred 66A4-2 and four of its hybrids reduced the prolific tillering of these genotypes. Early applications were maximally effective and increasing the dosage from 0.1 to 1.0 mg/plant slightly improved the treatment efficacy. Both auxiliary tiller number and dry weights of auxiliary tillers were reduced following early GA application. In field trials the latter character was reduced to 36, 20, 7 and 22% of the control values in 66A4-2, 66A4-2 × CG8, 66A4-2 × CM7, and CM49 × 66A4-2, respectively, following the earliest GA application. Promotions of height growth as a result of both leaf sheath and leaf blade elongation were only temporary as final heights were similar in GA treated and control plants. The inhibition of auxiliary tiller dry weight accumulation was not accompanied by changes in principal shoot dry weight. Thus, GA treatment early in the life cycle can reduce tillering in early-maturing maize without the undesirable side-effect of shoot elongation.Key words: Zea mays L., corn, suckers, plant growth regulators

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.

A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots. The research was established in a completely random design with ten treatments and three replicate pots. The plants were harvested four weeks after sowning, and leaf area per plant (LA), root volume (RV), longest root length (LRL), plant height (PH), fresh (RFW) and dry weight (ROW) of roots, shoot dry weight (SOW), RDW/SDW ratio, and total dry matter production (TDM) were determined. Significant varietal differences for all characters were found, except for LRL. The data obtained allowed to identify Cargill-163 as a poor genotype at low water supply. Danac-3006, FM-6, Sefloarca-91, Ceniap PB-8, and Tocorón-300 hybrids showed the best behaviour in terms of RDW/SDW ratio and root volume. On the other hand, root dry weight was identified as the best indicator and easiest characteristic to determine the drought-tolerance of maize plant.
