Germination of sweet corn (Zea mays L.) on moist filter paper or submerged in distilled water or hydrogen peroxide solutions was compared at different temperatures. Subsequent growth in soil was evaluated. Seedling growth from seed pregerminated on moist paper was superior to that from seed pregerminated while submerged in either water or H2O2 solutions. Overnight pregermination on moist paper at 32 C, which corresponded to the first emergence of the radicles, followed by planting in the field, generally resulted in hastened emergence, higher percentage emergence, and increased seedling green weights; however, there was no consistent hastening of maturity or increase in kernel yield in plots thinned to equal stands. Pregermination would probably be most useful with weak seed.

This research was carried out in November 2017 until Januari 2018 at Blang Krueng village, Baitussalam sub-district, Aceh Besar Regency and Physiology Laboratory, faculty of Agriculture, Syiah Kuala University. This research was conducted Randomized Block Design factorial pattern 3 x 2 with 3 replications. The factors studied in this research are mycoriza types and the population of  the plants. 3 types of mycoriza types are glomus mosseae mycoriza, gigaspora and the mixture of glomus mosseae and gigaspora. and 2 types of the population of  the plants are using one seed and two seed.

Introduction. Low seedbed temperatures at the planting and the direct sowing method can reduce the sweet corn germination. Transplanting may offer optimum environmental conditions for seed germination, early crop maturity, and increase sweet corn (Zea mays L. group saccharata) productivity. Boron deficiency depresses sweet corn yield through male sterility. Objective. To evaluate the effect of transplanting and the addition of boron in sweet corn production. Materials and methods. A field experiment was conducted from March 19 to June 20, 2020 at the Research Station of Horticulture Department and Landscape Gardening Architecture, University of Diyala, Baqubah, Iraq. Direct sowing and transplanting, and foliar application of boron at 0, 50, or 75 mg L-1 was evaluated to determine effects on the yield, the yield components, and water use efficiency of sweet corn cultivars: Roi Soleal, Seker misir, and Succar. Results. The cv. Seker Misir matured faster (57.5 days), had wider ears (4.53 cm), more kernel rows (16.0), the highest kernel yield (6.00 t ha-1), and a higher water use efficiency (WUE) (2.85 kg m-3). The cv. Succar had the longest ears (18.48 cm) and the heaviest fresh ears (251 g). Transplanting hastened the time to maturity (54.18 days), and produced the longest ears (17.91 cm), widest ears (4.52 cm), most kernel rows (15.96), heaviest fresh ears (229 g), the highest kernel yield (5.56 t ha-1), and the highest WUE (2.64 kg m-3). The 50 mg L-1 fertilizer treatment produced the longest ears (17.61 cm), widest ears (4.58 cm), more kernel rows (16.61), the highest kernel yield (5.64 t ha-1), and the highest WUE (2.68 kg m-3). The least time to maturity (57.72 days) and heaviest fresh ears (232 g) occurred with 75 mg L-1 of boron fertilizer. Conclusion. The use of 50 mg L-1 boron, as a foliar fertilizer, appears to be, next to the transplanting method, suitable for the cultivation of sweet corn plants to increase productivity and WUE.

Background: Drought is one of the major abiotic factors leading to diminishing growth, development and productivity of plants worldwide. Considering that germination is the first phase of growth which in large measure determines plant quality and yield, knowing the effects of different factors on this process is of major importance. This paper studies the effect of drought-induced stress on seed germination and seedling growth of Zea mays L. (the Sweet corn and the hybrid Pioneer B23). Methods: The effect of water stress was caused by different concentrations of mannitol: 5%, 10% and 20%. In the control, we used distilled water. The germination test was performed in three trials of 45 seeds each. The germination percentage, germination potential, drought resistance index were calculated at 3, 5 and 7 days. Growth of seedlings and biomass content were calculate at 14 days.Result: The results show significant differences between the variety and hybrid examined. The pioneer B23 seed germinated in larger number and more quickly. The Sweet corn variety seedling growth was completely absent after treatment with mannitol. The observed difference is certainly not just a consequence of higher mannitol concentrations, but also a difference in the water-retention capability of the variety and hybrid studied.

To reduce the existing yield gap of maize crop between research and farmer’s field, the experiment was carried out during the period from March, 2014 to June, 2014 at the experimental field of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh. The experiments were laid out in RCBD method with three replications and eight treatments including control viz. Treatment0 = control (no fertilizer), Treatment1=recommended dose N250 P50 K100 S25 Zn2 B1 kg ha-1, Treatment 2=American NPK+N250 P50 K100 S25 Zn2 B1, Treatment3=Bio-forge+N250 P50 K100 S25 Zn2 B1 , Treatment4=Wuxal+N250 P50 K100 S25 Zn2 B1, Treatment5=Peak+N250P50K100S25Zn2B1, Treatment6=Root Feed+N250 P50 K100 S25 Zn2 B1 and Treatment7=Nitro Plus+N250 P50 K100 S25 Zn2 B1 and three maize varieties namely Variety1=BARI Hybrid Bhutta-5, Variety2=BARI Hybrid Bhutta-6 and Variety3=BARI Hybrid Bhutta-9. Growth and yield contributing characters mainly plant height, cob length, cob weight, 100-kernel weight and kernel yield of maize crop were significantly influenced by the next generation fertilizers. Bio-forge along with other recommended fertilizers performed the best compared to other treatments of the study in aspect of kernel yield (5.95 t ha1) and statistically similar result showed by Root Feed along with other recommended fertilizers and produced 5.12 t ha1 kernel yield.
