The Effect of Plastic Mulch on Pests, Diseases, and Yield of Potato

Info Aktual

The decrease of potato yield in West Sumatra was caused by using of low seed quality, uncompatible of cultural practices, unproper environment, and damaged by pests and diseases. Plastic mulch may give better condition for potato growth. Results of some experiments showed that using plastic mulch increased the growth and yield of potato, especially for tubers class A and class B, and decreased bacterial wilt diseases (Pseudomonas solanacearum) intensity. Using of plastic mulch did not affect Liriomyza sp. and late blight disease (Phytophthora infestans) significantly.

Suporting Technology for Organic Agriculture

Info Aktual

West Sumatra’s vegetable was usually produced through intensive chemical input application. With high fluctuation of yield and agro input price, application of chemical product would not be economic and competitive. Healthy live style by slogan “back to nature” has canghed the human life style into minimizing chemical fertilizers, synthetic pesticides, and growth regulators in producing agricultural product. The agricultural product must have food safety attributes, nutritional attributes, and eco-labelling attributes. Technologies available for healthy vegetable crops cultural practice were: (1) LEISA (Low External Input for Sustainable Agriculture) technology, included deep land preparation, sanitation, using plastic mulch, using 30 t/ha of manure, 1 t/ha NPK, and rotation of pesticides, agonal pesticides (biologist, anabatic) and sintetic pesticides; (2) Take care and use of soil microorganism for increasing soil fertility; (3) Biopesticide developed from crops, animals, or microorganisms; (4) Crops, machines, and materials trapped for pest including pheromone, color, machine that trap insect pest; (5) Biofertilizer including fertilizers developed by using symbiotic or nonsymbiotic microorganisms; and (6) Decomposer microorganism like Trichoderma harzianum.

Study on Potato Cultural Practice at Agam and Solok Regencies

Info Aktual

A study was conducted at two main production areas of potato, Agam and Solok regencies, West Sumatra in 2006. The objective of this study was to evaluate the effectiveness of introduced technology for potato farming, i.e. fertilization, pests and diseases control, and use of mulch, compared to the locally traditional farmers’ practice. Cingkariang variety of potato was planted at Batagak, Agam regency, whereas Granola variety was planted at Alahan Panjang, Solok regency. Results of this study showed that the growth and yield of potato with introduced technology was better and higher than that of farmers’ practice. The yields of Cingkariang variety at Batagak was 8,770 kg/ha using introduced technology, whereas with farmers’ practice it was only 4,981 kg/ha. At Alahan Panjang, the yield of Granola variety was 9,574 kg/ha for introduced technology and 8,690 kg/ha for the farmers’ practice. The main pest found at the two locations was leaf caterpillar. The damaged crops by this pest at Alahan Panjang were 3.55% and 0.43% at Batagak. Liriomyza sp was found at Alahan Panjang with low damaged crops intensity. The main diseases infected potato crops at both locations were Phytophtora infestan and virus. The infected crops by Phytophtora infestan at Batagak were 77.95% for introduced technology and 100% for the farmers’ practice. At Alahan Panjang, the infected crops by this disease were 50.90% for introduced technology and 23.89% for the farmers’ practice. The virus only infected potato crops at Batagak with the damaged intensity was only 5.25%.
