Abstract

The purpose of this esearch was to study the efficiency in using HeUcoverpa armigera Nuclear Polyhedrosis Virus (HaNPV) and Trichogrammatoidea armigera Nagaraja to improve and simplify' Integrated Pest Control recommendation package for farmers. This research was conducted in Asembagus Experimental Station, Situbondo, East Java, from December 1997 to May 1998. Cotton plants were planted in monocultue system and the pests were controlled using IPM-3 recommendation package. This research was designed in randomized block with 3 treatments, and 3 eplicates. HaNPV spraying was based on the treshold; releasing T. armigera was based on the theshold, and the schedule of insecticide spraying was every 10 days. The esult showed that treatment of eleasing T armigera followed by application of insecticide was the most efficient (B/C ratio ■ 1.39), compared with the insecticide spraying schedule (B/C ratio = 1.21), and spraying of HaNPV fB/C ratio =1.12).

Abstract

Application of technology package of cotton intercropped with soybean in paddy field after riceThe research was conducted in Mantup Village, Larnongan from Feb¬ ruary to July 1998. The objective of the research was: (1) to know the farmers' adoption level of the recommended technologies, and (2) to increase the income of cotton farmers The research covered 30.47 hectaes and 83 cooperative fanners. For comparison, the other 29 IKR farmers surrounding the area were also involved The components of technology that are recom¬ mended for the cooperative farmers include the usage of delinted seeds and the appropiate vaiety of cotton (ISA 205) and soybean (Wins), simultaneous planting ight away after ice, proper application of watering aid fertilization and application of fPM for cotton intercropped with soybean. The observa- tions were made for the number of farmers who applied the recommended technologies, production inputs and their price, the use of labor, production of cotton and soybean. Data analysis was done as per tabulation and enter¬ pise The average of farmers' adoption level of the recommended technology was around 89%. The productivity of cotton and soybean obtained by cooperative farmers were 1 630 kg/ha and 747 kg/ha. respectively. These were higher than those of IKR farmers wbo obtained 1212 kg/ha and 735 kgAia for cotton and soyben. respectively The income of cooperative farmers was Rp 1 901 300 and of DCS farmers was Rp I 197 825 Therefore, the cooperative farmers have a higher income than that of OCR fanners, i.e. Rp 703 475 or 58.73%.
