Each treatment consisted of 5 plants, the number of plant are 200 plants. asperellum + spraying frequency of 3 times). asperellum + spraying frequency of 2 times), J ( T. asperellum + spraying frequency of 1 times), I ( T. viren + spraying frequency of 3 times), H ( T. viren + spraying frequency of 2 times), G ( T.
viren + spraying frequency of 1 times), F ( T. harzianum + spraying frequency of 3 times), E ( T. harzianum + spraying frequency of 2 times), D ( T.
harzianum + spraying frequency of 1 times), C ( T. The research was arranged in randomized block design non factorial, consisted of 10 treatments and 4 replications, i.e : A = control, B ( T. The choice of location was based on a history of the cocoa pod disease in the previous period or the location was endemic.
This study was conducted in farmer's field in The East Aceh District, at June to Desember 2014. Qualities observation of seed were watched colour, size and protein degree.The research objective was to determine the effect of Trichoderma species and spraying frequency on the intensity of black pod disease ( Phytophthora palmivora) and cocoa yield. Variety were not significantly different on number of branch 9 weeks after planted, total peds, percentage pods producing seed, total seed per pod, total pod per plot, number of seed per plot, seed weight per plot, dry weight of shoot, dry weight of root and grow plant percentage. Varieties showed significantly different on plant height 2-9 weeks after planted, time of flower initiation, total pods per plant, total pops, total pod producing seed, number of seed per plant, number of seed per plot, 100 seed weight, seed weight per plant, and percentage of peds producing pod. The data was analyzed by Analysis of Variance and continued with Duncan's Multiple Range Test. The experiment used Randomized Block Design with variety treatment that consists of six varieties : Gajah, Jepara, Biawak, Landak, Komodo and Simpai, with four replications. The experiment conducted at BBI Palawija Tanjung Selamat, Deli Serdang (± 57 meters above sea level) from April to July 2012. The aim of the research is to get peanut with high yield and best quality at Clay Texture of Soil. Clay Texture of Soil has capability to defend water and soil minerals, but low infiltration rate, organic substances and Nitrogen, also big cracked in dry season because particle clay of soil was shrink. Peanut is the second legums largest planted in Indonesia after soybean.
