DETERMINATION OF PROPOSED MAXIMUM RESIDUE LIMIT OF DELTAMETHRIN IN BLACK PEPPER (PIPER NIGRUM L.)

Research Article of American Journal of Agricultural Research DETERMINATION OF PROPOSED MAXIMUM RESIDUE LIMIT OF DELTAMETHRIN IN BLACK PEPPER (PIPER NIGRUM L.) Yap Chin Ann, Zehnder Jarroop, Lawrence Tuah, Sang Jam Research and Development Division, Malaysian Pepper Board, Lot 1115 Jalan Utama, Pending Industrial Area, 93916 Kuching, Sarawak, Malaysia Residue trials of deltamethrin in black pepper (Piper nigrum) were conducted to estimate the maximum residue limit (MRL). Five residue trials were conducted at three commercial growers’ plots in Johor, Perak and Sarawak (Malaysia). The study plots contained 120 mature pepper vines which were selected and treated with deltamethrin using the manufacturer’s recommended rate (0.01 kg a.i./ha). The insecticide was applied with a motorized sprayer on monthly intervals. Green pepper berries samples (500g) were randomly collected from the plots at 1, 3, 5 and/or 7 days after the last spray. Analytical procedure of deltamethrin extraction was validated prior to actual analysis. Satisfactory recoveries ranging from 86.2% to 110.2% were obtained for the fortified pepper berries samples. The limits of detection and limits of quantification for deltamethrin were 0.521 μg kg−1 and 1.63 μg kg−1, respectively. Results showed that deltamethrin residues were at the low level with the residue value ranging between <0.08 mg/kg to 0.032 mg/kg. Dissipation of deltamethrin in black pepper berries followed first-order kinetics, and the mean half-lives was 3.2 days after the last treatment. The results also indicated that pepper berries could be safely consumed after 5 days of application. The determined value of proposed MRL for deltamethrin was 0.5 mg/kg. The Dietary Intake Assessment based on Malaysian Food Consumption Pattern confirmed that the proposed MRL concentration will not cause health risks to consumers. Results obtained also showed that all the pesticide residue were stable at -20oC and did not show any significant decrease or increase in the ...

VERTICAL LAYERS OF TITHONIA DIVERSIFOLIA FLAKES AMENDMENT IMPROVES PLANTAIN SEEDLING PERFORMANCE

Research Article of American Journal of Agricultural Research VERTICAL LAYERS OF TITHONIA DIVERSIFOLIA FLAKES AMENDMENT IMPROVES PLANTAIN SEEDLING PERFORMANCE C. A. Ewané1,2*, A. Meshuneke1, R. N. Tatsegouock 1 and T. Boudjeko1,2 1Laboratory of Phytoprotection and Plant Valorization, Biotechnology Center, University of Yaoundé 1, P. O. Box 3851, Messa-Yaoundé, Cameroon; 2Department of Biochemistry, Faculty of Science, University of Yaoundé 1, P. O. Box 812, Yaoundé, Cameroon. Plantain seedlings availability in sub-Saharan countries are very weak to support a high productivity level required. The plantain cultivation faces problem of the seedling’s unavailability in quantity and quality for intensification of this crop. The amendment of PIF substrate production with natural products could be an alternative to this problem. This study objective is to evaluate the effect of vertical layers of Tithonia diversifolia flakes on the performance of PIF plantain seedlings in terms of vegetative growth and susceptibility to black Sigatoka disease (BSD) in nursery. The vertical layer of T. diversifolia flakes amendment was introduced in the propagator in the presence of the control without amendment in controlled and uncontrolled conditions for shoots, then seedlings generation, followed by the evaluation of the vegetative growth parameters, the inoculation of the leaves with Mycosphaerella fijiensis and the pool of biomarkers evaluation. The treatment increases the germination rate, the number of shoots, the height and the diameter of shoots, the area of leaves as well as the seedlings roots, but also protects the seedlings against BSD up to about 56% compared to the controls. It also enhances the accumulation of proteins, polyphenols content and enzymes such as peroxidase, polyphenoloxidase and glucanase. The dual role of the vertical layer of T. diversifolia flakes in seedling production as a biofertilizer and as a biopesticide was revealed in this research. Taking into account this bad herbs flakes as a tool for sustainable ...

Prosopis cineraria (Ghaf): An Unconventional Desert protein rich supplement

Research Article of American Journal of Agricultural Research Prosopis cineraria (Ghaf): An Unconventional Desert protein rich supplement Saif Al Ghais, Vibha Bhardwaj*, Pramod Kumbhar Environment Sustainability Department, Environment Protection & Development Authority (EPDA), Ras Al Khaimah, UAE Prosopis cineraria (Ghaf) is not well known as a rich and sustainable source of protein for many people in the world. It emphasis on its broad food and non-food applications, nutritional values and health benefits. This research was carried out to meet the increasing demand of protein, alternative strategies and unconventional sources of protein for human and animal nutrition. This is probably the first research work which provides a comparative study between the protein content of ghaf leaves with different species of fish muscle protein. Fish muscle homogenate was prepared using ice cold distilled water. The muscle homogenate of Euthynnus affinis showed highest protein 137.5 mg/g. The other fishes muscle protein were Carangoides chrysophrys (43.33 mg/g), Lenthrinus lentjan (105 mg/g), Sardinella longiceps (104.17 mg/g), Pomacanthus maculosus (81.67 mg/g), Nemipterus japonicus (111.67 mg/g), Lutjanus ehrenbergi (99.17 mg/g), Gerres oyena (107.5 mg/g), Argyrops spinifer (100.83 mg/g), Terrapin jarboe (82.5 mg/g), Tilapia mossambica (54.72 mg/g). Ghaf tree is a keystone species having multiple beneficial uses from combating desertification and improving soil fertility in arid environments to being an essential food source, as well as a source of fuel, shelter and medicine for both humans and animal species. The Ghaf leaves extracts were tested for protein content analysis. The protein content in Ghaf leaves was found to be 88.61 mg/g. Thus, the research results revealed that Ghaf leaves has almost similar amount of protein as compared to fish muscle protein and can be used as protein supplement for growth and metabolism of body.

Research Article of American Journal of Agricultural Research Relative plant parts, chemical composition and in vitro gas production evaluation of different Watania corn hybrids silage Gaafar, H.M.A.1; W.A. Riad1; Ghada S. El-Esawy1 and M.E.A. Nasser2 1Animal Production Research Institute, Agricultural Research Center, Dokki, Giza, Egypt. 2Animal Production Department, Faculty of Agriculture, Alexandria University, El-Shatby, Alexandria, Egypt. Four Commercial corn hybrids included 3 white hybrids, single crosses (SC) Watania 4 (W4) and Watania 6 (W6) and three-way cross (TWC) Watania 11 (W11) and 1 yellow hybrid (SC) Watania 97 (W97) were cultivated at 30 thousand plants per feddan, harvested at 92 days, chopped and ensiled in plastic bags for 35 days. Results revealed that W6 showed the highest ear content (36.60%), W97 the highest stems content (52.47%) W11 had the highest leaves content (18.65%). Watania 11 showed higher CP content and W97 had higher CF and fiber fractions content, while W6 had higher contents of EE, NFE and NFC in comparison with the other hybrids. Gas production at different incubation times as well as gas production from the immediately soluble fraction (a), insoluble fraction (b) and soluble and insoluble fractions (a + b) as well as the gas production rate constant for the insoluble fraction (c) values were significantly (P<0.05) higher for W6 than that of W97 with insignificant differences with both W4 and W11. Gas production from the fermentation of soluble fraction (GPSF) of W6 and insoluble fraction (GPNSF) of W4 and W6 were significantly (P<0.05) compared to W97. The concentration of SCFA was significantly (P<0.05) higher for W4 and W6 compared to W97 and not significantly (P>0.05) different with W11. The predicted dry matter intake (DMI) and organic matter digestibility (OMD) of corn silage were higher significantly (P<0.05) for W6 than that of W97, whereas were nearly similar for ...
