The Introduction Of An Anticipative Rice Plant Technology On El-Nifio In Grobogan Regency

Abstract

The climate anomaly   had impact  on agricultural sector in Central Java for the last five years. Abaout 15.000  paddy  fields had;    12.889   was flood and 8,448 acre was faidure to be  harvested. The research  needs  related  to fluctation of farm productifity as effect of climate change are needed  by policy  makus and practicioners.   Other aspect which  is also impartant to be assessed is  switability   of farming system practiced on the location  in  response to cli• mate change. This assessment can be done using simulation  model or model existing on the farm.  The anticipative rice culture technologi on  El-Nifio  was assessed in  Sengon Wetan Village, Kradenan subdistrict,   Grobogan  Regency. Participatory Rurral Appraisal (PRA) survey was conducted before introducing the technology. The exeperiment design of randomly complete block desigh was employed using  4 treatments with 5 replicaton.  Those treatments were :   (1) the farmer technology   package by the width of 2.500  meter square,  (2) the intro• duction technology  package by the width of 1.000 meter square, (3) the farmers treatment package repaired by the width of 500 meter square and (4) the control.  Parameters measured were plant heght,  number number  of tillers,   grain yield and Content of grain. The results indicated  plant hight,  maximum plant height and maximum number of tillers of technology package introduced were 86,98 cm, 91,8   cm and 20,8 respectively. tillers  per plants, respec• tively.  In addition,  the rice production  reached 50,8 kg  per 100 m2 with 19,62  % of wath content.  Whereas number of tillers at 60 day after transplanting (DAT) plants of the farmer technology package was 15,78 tillers per plant.
