<![CDATA[Trichoderma sp and cow manure as biofertilation that supports the growth and production of horticultural and food crops. The aim of the research is to determine the application time of Trichoderma sp on purple eggplant plants, to determine the interaction between the Trichoderma sp fungus and which dose of manure provides the best growth and production on purple eggplant plants. This research method was prepared based on a split plot design (SPD), with 12 treatment combinations, each treatment repeated 3 times so that there were 36 experimental units. The main plot is the dose of cow manure (p), consisting of 3 levels, namely, p1 (cow manure dose 500 g/polybag), p2 (cow manure dose 750 g/polybag), p3 (cow manure dose 1000 g/ polybag). The subplot is the application time of Trichoderma sp (a), consisting of 4 application times, namely, t0 (without Trichoderma sp), t1 (1 week before planting), t2 (at planting time), t3 (1 week after planting). The treatment of Trichoderma sp application time has no effect on the growth and production of purple eggplant plants due to the dose of Trichoderma sp is not optimal, giving a dose of manure 1000g.polybag is more effective than 750g.polybag and 500g.polybag on production (length and weight of fruit/plant) purple eggplant. The interaction between the dose of manure 500g.polybag with Trichoderma sp application time 1 week before planting gave the best effect on the growth of crown weight, root weight and production (length of fruit/plant) of purple eggplant]]>
