Two experiments were conducted in 1987-88 in St. Lucia with a view to extend the dormancy of white yam (Dioscorea alata L). Experiment 1 compared different harvest dates, different storage temperatures and presence or absence of the tuber "head" in cultivar Oriental. Experiment 2 studied the effect of gibberellic acid (GA) solution (1000 p/m) on the dormancy of different cultivars of white yam. Tubers from the early harvest (15 November) had the longest dormancy period (over 7 months), which decreased progressively with delay in harvesting. Storing yam tubers at 20 ± 2°C extended the dormancy by over 5 months as compared to storing them at 30 ± 2°C. The presence or absence of the tuber "head" had no effect. The interaction effects due to dates of harvest X storage temperatures and storage temperatures X manipulation were significant. Cultivars of white yam differed significantly in their dormancy period. Treating the harvested tubers with GA (1000 p/m) for 2 hours extended the dormancy by over 4 months as compared to that of the control (water) treatment.

cayenne pepper plant (Capsicum frutescens L.) is one of the popular vegetables comodity in Indonesia. cayenne pepper plant used as main ingridients for kitchen’s need, sauce industry, chili powder, instant noodle, and pharmaceutical industry. The demand for cayenne pepper plant in Indonesia is considerably high, about 4kg/capita/year. Antrachnose diseease caused by Colletotrichum sp is on of the major problem in cayenne pepper plant cultivation. Colletotrichum sp is from Nectrioidaceae family that has plenty of aservulus beneath the cuticule or on the surface, the diameter is up to 10 nm, black colored and many setae. Several bacteria has antagonist feature either around the root, or endophytes with the roots. Bacillus sp has antagonist feature is consider to treat the Antrachnose disease. Bacillus sp is a marine bactreia that can produce antibiotic to fight pathogen. However, from this study there are two different antagonist activites between two isolate due to different chytinolytic activitiy between the two isolate.

Abstract: Because pesticides are ubiquitous and focused on the food chain, they are a substantial source of possible environmental danger to humans and animals. The highest extremely hazardous herbicides to be launched in 60 years ago is paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride). Although most nations have prohibited or severely limited the use of paraquat (PQ), it is still used in others, particularly in Nigeria. As a result, the present study used a spectrophotometric method to look for PQ in some vegetables, crops, and fruits in Abeokuta that are commonly consumed. The presence and amounts of PQ residues were assessed in 150 samples of various vegetables, crops, and fruits (harvested at Fadama field of the University of Agriculture, Abeokuta). PQ residues were detected in Talinum triangulare, Corchorus olitorius, Amaranthus caudatus, Cratylia argentea, Capsicum frutescens, Lycopersicum esculentum, Raphanus sativus, Zea may, and Dioscorea alata at 0.130.02, 0.27+0.02, 0.06+0.01, 0.10+0.03, 0.15+0.03, 0. Using this technique, no paraquat residues were found in M. paradisicica or C. papaya. At 0.05-1.0 ppm fortification level, the technique yields a mean recovery of over 80% and is reproducible with a total coefficient of variation of 8.0 percent (n=10). All residual levels found were under the PQ tolerance or pesticide maximum limits.

This study was conducted to evaluate the quality characteristics of Dioscorea rotundata and Dioscorea alata as alternative to potato in French fries production and effect of frying time on the quality index and acceptability of resultant yam chips. The yam chips were pretreated by blanching for 10minutes at 90o C, and soaking in 5% citric and sodium metabisulphite acid solution for a period of 30minutes. The treated blanched yam chips were deep fried at 170o C for 21 minutes, but the chips were withdrawn at intervals of 3minutes to determine the moisture content, textural properties and sensory attributes of the chips. The proximate composition of the fried chips was evaluated using established procedures of the Association of Official Analytical Chemists (AOAC). The textural properties such as Peak force and deformation at break of the deep fried chips were determined using a Universal Instron testing machine.The fried yam chips were subjected to sensory analyses (colour, crispiness, mouthfeel, taste, overall acceptability) using a 9- point Hedonic scale. Data obtained were subjected to Analysis of Variance ANOVA and means separated by Duncan Multiple Range test. The result of the proximate analysis on the two varieties of raw yam tubers showed that wateryam (D.alata ) had a significant (p>0.05) higher moisture content (69.49%) and protein values (7.60%) than white yam (D. rotundata) having 64.84% and 4.55% respectively).D alata had a significant (p>0.05) high fibre content of 2.34 % compared to D rotundata which had 1.42%. On the other hand, D. rotundata, has greater amount of carbohydrate (26.70%) than D. alata with (20.18%). A significant (p< 0.05) lower moisture content existed for the fried chips samples from 3 minutes to 18 minutes for both white yam (54.32-32.76%) and water yam (61.32- 31.03%).Frying time had a significant lowering effect on the moisture content of fried chips. White yam (D. rotundata) showed significantly (p>0.05) high force at peak than wateryam (D. alata), with values of 26.30N, and 7.30N respectively. Results showed that frying time had significant (p>0 05) effects on the peak force and deformation at peak of the fried yam chips for the two varieties. The pre-treatments given to the yam chips produced from the two yam varieties, gave some desirable sensory characteristics. The sensory scores showed that fried white yam chips had a significant (p>0.05) highest score (7.14) compared to wateryam fried chips (6.39) at 21st minute frying time even in terms of colour, taste, mouthfeel and overall acceptability. The use of yam as a substitute for potato in French fries production would make fries to be more affordable and promote its utilization in French fries production.

Mikroba Bacillus subtilis merupakan agen pengendali hayati mempunyai kelebihan sebagai Plant Growth Promoting Rhizobacteria (PGPR) yaitu dapat berfungsi sebagai biofertilizer, biostimulan, biodekomposer dan bioprotektan. Tujuan penelitian mengetahui potensi B. subtilis dalam merombak bahan organik sebagai usaha meningkatkan ketersediaan bahan organik tanah yang semakin menurun. Penelitian menggunakan Rancangan Petak Terbagi dengan berbagai  bahan organik sebagai petak utama (B0 = tanpa bahan organik, B1 = kotoran ayam,  B2 = kotoran kambing, B3 = kotoran sapi) dan aplikasi B.subtilis sebagai anak petak (A0 = 0 cc/L, A1 = 5cc/L, A2 = 10 cc/L, Pengamatan meliputi variabel tinggi tanaman, indeks luas daun, jumlah buah per tanaman, berat buah per tanaman, dan bahan organik tanah. Data pengamatan  dianalisis ragam  menggunakan  Statistical Product and Service Solutions (SPSS) versi 25 dan dilanjutkan dengan uji Duncan untuk mengetahui signifikansi perbedaan antar perlakuan. Hasil penelitian menunjukkan tidak terdapat interaksi antara bahan organik kotoran ternak dan konsentrasi B. subtilis terhadap semua variabel pengamatan. Potensi B. subtilis sangat baik dalam mendekomposisi bahan organik yang ditunjukkan dengan peningkatan bahan organik, dan hasil terbaik pada kotoran  sapi (B3) dan konsentrasi B. subtilis 15 mL/L masing-masing sebesar 46.47 % dan 34.76 %. Variabel pertumbuhan tidak berbeda nyata kecuali tinggi tanaman dengan pertambahan tinggi paling banyak pada pemberian kotoran kambing sebesar 170.69 %.
