Perbedaan Tinggi, Jumlah Daun, dan Diameter Batang Tanaman Jagung (Zea mays L.) pada Sistem Agroforestri Penanaman Lorong (Alley Cropping) dan Tumpang Sari di DAS Mikro Desa Tukad Sumaga, Kecamatan Gerokgak, Kabupaten Buleleng

Differences in Height, Number of Leaves, and Stem Diameter of Corn (Zea mays L.) in Alley Cropping and Intercropping of Agroforestry Systems at the Micro Watershed of Tukad Sumaga Village, Gerokgak District, Buleleng Regency. Degraded land as a result of land conversion has a very bad impact on the agro-ecosystem. Land conversion caused by the increasing needs of the population. The majority of the livelihoods of the people in Tukad Sumaga village are farmers. The availability of forage is very important to be maintained. Corn plants, in addition to their production in the form of corn, forage fodder on corn plants are very important for the availability of cattle feed. This research was conducted on 28 DAP maize (Zea mays L.) in alley cropping system and intercropping in the micro watershed of Tukad Sumaga Village. The results showed that the highest average plant height, leaf number, and corn stalk diameter were found in the alley cropping system namely 1.03 m, 7.31, and 1.59 cm. There was no significant difference between the height of corn plants in alley cropping and intercropping systems. There is a significant difference between the number of leaves and the diameter of the stems of maize in alley cropping and intercropping systems.

The aim of this work was to evaluate the attenuating effect of the nitric oxide donor (sodium nitroprusside-NPS) on the ecophysiological responses of corn plants (Zea mays L.) submitted to copper toxicity. The corn seeds of the K9606 VIP3 variety were soaked for 48 hours in Germitest with solution containing treatment with sodium nitroprusside Na2 [Fe (CN) 5 NO] 2H2O (0, 200 and 300µM), sodium ferrocyanide Na4Fe (CN) 6 ( 300, 100 and 0 µM) respectively and deionized water (control), sown in buckets with 15 kg of soil incubated for 50 days containing copper concentrations CuSO4.5H2O (0, 60 and 200 mg kg-1). The design consisted of randomized blocks with 12 treatments and 4 repetitions, making a total of 48 plants. in ecophysiological variables: height, leaf area and number of leaves, stem diameter increased by 32, 66% and 11.29% in the treatments with 60 mg kg-1 of copper and 200 mg kg-1 of copper, respectively. There was no effect of treatments on the chlorophyll content measured by the SPAD index and gas exchange. The chlorophyll a fluorescence variables indicate that the concentration of 200 mg kg-1 of copper caused damage to the structure of the PS II reaction center complexes and indicate a slightly protective effect of nitric oxide-NO present in sodium nitroprusside and cyanide present in sodium ferrocyanide, reflecting a smooth functioning of the maximum activity of photosystem II and the electron transport chain.

Antioxidants have the potential as photoprotectors, therefore, plants containing phenolic compounds can be used in the prevention of free radicals. For this reason, researcher is interested in further researching the phytochemical screening, antioxidant activity and sunscreen testing from extracts of stems, leaves, hair and leaf wrapping from corn (Zea mays L.). The samples used were corn plants (corn silk, corn leaves, corn stalks and leaf wrapping corn) originating from Kauditan area, North Minahasa. The results of the study showed that the leaf contained saponin and flavonoid compounds, the stem contained alkaloid and saponin compounds, the hair contained alkaloid and flavonoid compounds, and the leaf wrapping only contained alkaloid compounds. The highest to lowest total phenolic content values starting from the stem were 46.93 μg / mL, the leaf wrapping 37.76 μg / mL, the leaf 26.63 μg / mL and hair 14.49 μg / mL. The leaf has the highest antioxidant activity with a value of 72.81% followed by 62.87% stem then wrapping leaf 43.13% and finally hair 29.14%. The SPF value of the stem was included in the ultra protection with a value of 16.117 followed by the leaves included in the maximum protection with an SPF value of 10.902. While the hair with SPF value of 0.6 and wrapping leaf with SPF value of 0.222 are included in the minimum protection.

Aims: Maize (Zea mays L.) is a major staple food for millions of people in Côte d’Ivoire. Due to its high productivity and low cost of calorie it is preferred crop for food security of the country. Thus, this study was conducted to assess nutritive quality of maize produced and stocked in five purposively selected regions of Côte d’Ivoire which represents five agroecological settings. Study Design: A total of 1500 samples of maize as grains, epis and spathes were collected at rate of 500 samples by region (Gbêkê, Poro, Hambol, Indénié-Djuablin and Gontougo) and sent to the laboratory in order to analyse their nutritional quality. Place and Duration of Study: This study was carried out during March 2016 to January 2017. The collected sample were carried out at the laboratory unit of Food Sciences and Biochemistry of the Félix Houphouët-Boigny University, Abidjan. Methodology: Proximate analyses were carried out using standard methods AOAC (2000). Results: The results show significant difference from the biochemical compositions of maize type and region. Mean value intervals were as follow: dry matter (85.83 – 91.42%), ash (1.19 - 2%), proteins (7.99 - 9.32), lipids (3.21 - 4.47), carbohydrates (71.80 - 77.94), starches (62.30 - 68.44%), fibers (5.03 - 5.83%), total sugars (2,13 - 2.99%), reducing sugars (0.33 - 0.66%), free fat acidity (1.86- 4.50%), peroxide value (1.34 - 3.07 meq O2/kg), iodine value (100.93 - 130.56 g I2/100 g), unsaponifiable (0.89 - 1.54%) and energy values (357.88 - 374.39 kcal). Conclusion: A significant variability from one region to another can be noticed at level of maize quality regardless the type of maize. The nutritive quality of maize seems to be tied to postharvest treatments (drying), type of storage (epis, grains and spathes) and structure of storage.
