Sweet Corn

Jagung manis (Zea mays saccharata Sturt) merupakan salah satu jenis tanaman yang dipanen muda dan banyak diusahakan di daerah tropis.  Jagung manis atau sering disebut sweet corn dikenal di Indonesia pada awal tahun 1980  dan merupakan salah satu komoditas sumber pangan yang penting, karena jagung manis memiliki nilai gizi yang berbeda dengan jagung biasa. Kandungan yang terdapat pada jagung manis antara lain 70,7% karbohidrat, 13,5 % air, 10,0 % protein, 0,4 % lemak dan zat-zat lain. Salah satu teknologi yang dapat digunakan untuk meningkatkan produksi dan pendapatan usaha tani jagung manis adalah urin kelinci sebagai pupuk organik cair (POC). Pengaplikasian POC urin kelinci dapat meningkatkan hasil jagung manis sebesar 173 kg/125 m2 (13,84 ton/ha), sedangkan produksi jagung manis tanpa POC urin kelinci adalah 129 kg/125 m2 (10,32 ton/ha). Pengaplikasian POC urin kelinci meningkatkan pendapatan usaha tani dengan R/C ratio lebih tinggi yaitu 1.83, profitabilitas 83.7% dibandingkan dengan tanpa POC urin kelinci yaitu sebesar 1.70 dengan  profitabilitas 70

Salinity Levels

An experiment was carried out hydroponically under laboratory conditions to investigate the effect of salt stress on several physiological and biochemical parameters of three sweet corn (Zea mays L. var. saccharata) genotypes: lines 6-13, C-6 (pollen source) and their heterotic F1 hybrid ?Zaharina?. The degree of salinity tolerance among these genotypes was evaluated at three different sodium chloride (NaCl) concentrations: 0 mM, 100 mM, 125 mM and 150 mM. Seed germination, plant growth and biochemical stress determining parameters such as malondialdehyde (MDA), proline content and hydrogen peroxide (H2O2) levels were compared between seedlings of lines and hybrid. The obtained results indicated that both lines and hybrid have similar responses at different salinity levels for all examined traits. All the seedlings? growth parameters, such as germination percentage, root length, shoot length, root and shoot fresh and dry weight, decreased with increasing salinity level. MDA, proline and H2O2 increased at different saline conditions in comparison to the control. Based on the results, of the three genotypes examined, the hybrid Zaharina, followed by line C-6, was more salt-sensitive than line 6-13 in salt stress condition.

Millet Seed

The wild type of broom corn millet (Panicum miliaceum) is a serious emerging weed currently prevalent in New Zealand sweet corn (Zea mays) crops This study shows its seed is nearly twice the weight of other common grass weeds and can germinate in the temperature range 1634C with 50 germination at 26C and greatest germination occurring at 31C At 15C it took 8 days for seedlings to emerge but required only 4 days at 25C Seed was able to emerge from depths of up to 170 mm in a range of soils Experiments showed that broom corn millet seed can persist in the soil for longer than 2 years in the field but is killed in silage stack and bales Immersion in stock effluent for up to three months reduced seed germination to less than 40 These characteristics are discussed in relation to herbicide and management control options for this weed

And Control

The effect of chilling temperatures on the porphyrin pathway leading to chlorophyll was studied in Seneca Chief hybrid sweet corn. One-week-old seedlings grown at 28 °C in a 14 h light: 10 h dark photoperiod synthesize negligible amounts of chlorophyll when exposed to 12 °C for a subsequent 6 d. When the chilled plant is then brought back to 28 °C, chlorophyll synthesis is restored to control levels. Little difference in carotenoid content was detected between chill-stressed and control tissue even after 4 d of stress. Small differences in the chlorophyll content per 106 chloroplasts could be detected between stressed and control seedlings. Etiolated seedlings synthesize negligible amounts of chlorophyll or its precursors when illuminated at 12 °C. Incubation of tissue with aminolevulinic acid at various temperatures from 12 to 22 °C resulted in an accumulation of precursors comparable to 28 °C control tissue. The ability of etiolated tissue to accumulate aminolevulinic acid was negligible when illuminated at 12 °C as compared with that in tissue illuminated at 28 °C.
