Menekan Kerentanan Budidaya Gandum (Triticum aestivuml.Var. Dewata) Akibat Perubahan Pola Hujan Melalui Model Tumpangsari Dengan Tembakau (NicotianatabacumL.)

Abstract

This articel is a review of research on intercropping between wheat and tobacco in the highland of Temanggung, Boyolali and Magelang district wich unexpectedly experienced in a periode of excessive rainfall during the growing season of 2010. The intercropping model that was applied were the monoculture of wheat; monoculture of tobacco; tobacco population fixed + 1 line of wheat; tobacco population fixed + 2 lines of wheat; population of tobacco : wheat (1:1). The Experiment design of the study is The Randomized Block Design, Factorial (2 factors with 5 replications each model). The most obvious impact is the yield of the wheat much lower than its potential, due to the sensitivity of wheat plan in high rainfall, during both vegetative and generative phase. However, model intercropping of tobacco + 1 line of wheat, give the LER (Land Equivalent Ratio) are highest among the other models, namely 1.8. In the meaning of wheat cultivation this aspect implies that intercropped whith tobacco is more profitable than growing wheat in monoculture, especially in the face of changes in rainfall patterns that are essentially difficult to be predict
