Abstract

Sukoharjo Regency, Central Java, is an example of successfully implementing rice planting using the Planting Index 400 (IP-400). This study aimed to analyze the difference in total farming costs between IP-400 and non-IP-400 rice varieties and their sustainability. Farmers in Sukoharjo have succeeded in planting rice three to four times a year in rice fields with technical irrigation. This activity was carried out in five stages, i.e. 1) a Discussion with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Central Java and his staf; 2) Focus Group Discussion (FGD) with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Heads of Farmer Groups and their members, Delegates from the Directorate General of Food Crops, Ministry of Agriculture, as well as related parties; 3) Field visits to rice seed entrepreneurs; 4) Field visits to "integrated farming" entrepreneurs who implement IP-400 rice cultivation; and 5) Field visits and interviews with farmers accompanied by extension workers and the Department of Agriculture as farmer advisors. Socialization and discussions have effectively increased stakeholders’ understanding of the implementation of IP-400 rice planting. This success is due to adequate technical support and infrastructure and close cooperation between farmers, local governments, and other related parties. By continuing these efforts and adapting to local conditions, the IP-400 program can become a model for other regions to sustainably increase rice production

Abstract

Topographical tetrazolium (TZ) pattern to determine viability, vigor and field stand on soybean seeds cv. Burangrang was studied.  Laboratory test for standard germination, vigor index, speed of germination, accelerated aging, seedling growth rate and field performances were performed on five lots (A,B,C,D,E) of soybean seeds.  The viability and vigor categories of each pattern were determined by Root Mean Square (RMS), regression, and correlation analysis.  Ten topographical patterns were recognized. The laboratory test results and field performances were compared with topographical pattern. Combination of patterns 1,2,3,4 (embryonic axis and cotyledon completely and/or gradually stained) selected as viable category as it gave the least RMS value, the highest determination (R2) and correlation (r) coefficient with standard germination (RMS=6,46; R2=0,37; r=0,61). Combination of patterns 1,2,3 (embryonic axis and cotyledon completely stained) selected as vigor category as it gave the least RMS value, the highest R2and r with relative speed of germination (RMS=7,96; R2=0,44; r=0,66), vigor index (RMS=6,66; R2=0,36; r=0,6), field emergence (R2=0,79; r=0,89) and field stand (R2=0,65; r=0,80). The combination of patterns 1,2,3 is recommended for estimating field emergence and field stand.   Key words :  Tetrazolium, topographical pattern, viability, vigor, accelerated aging, field stand, soybean seed.
