EVALUASI RESPON PERTUMBUHAN DAN HASIL VARIETAS JAGUNG ASAL TIMOR PADA PERBEDAAN KELAS LAHAN KERING BERBATU

Abstract

Local resources is the rocky dry land have the potential to be developed as productive land if the selection of technology and types of varieties adaptive location.  T he problem is the least information abouton the nature of agronomy and the production of  adaptive local corn varieties at rocky dryland. The study aims to : 1)  gotdata about the agronomic character of local corn varietiesat different class rocky dry land. 2) obtain data about productive corn on rocky dry land. Experiment using R andomized Block D esignwith 9 replications. Treatment is 3 varieties of maize: 1) Haikesak Putih , 2) Tastim I Putih , and 3) Bunga Merah Fatumonas. Different conditions of rocks on the surface are different locations. C riteria of a rocky dry land  class consists of Class 2: consists of  rocks that exist on the surface as much as  0.1-3.0% and the small rock is the distance is about 1 meter. Class 3 : consists of  rocks that exist on the surface as much as  3.0% -15% and the small rock is the distance is about 0,5 meter. Class 4 : consists of  rocks that exist on the surface as much as 15-25% and the small rock is the distance is about 0,3 meter. Observation variables consist of: 1)Growth: a) H eight of plant , b) Diameter of stem, c) Width of Leaf, and 2) Production: a) W eight of maize per plant ,  b) Y ield per hectare . The research results showed  that the local corn varieties of Bunga Merah Fatumonas have the best agronomic at different class of rocky dry land.  T he local corn v arieties of Bunga Merah Fatumonas provide the best response to: height of plant , weight of maize per plant , and  yield per hectare .  Key word: Rocky dry land class, best response
