PENGARUH PENGHEMATAN PUPUK BUATAN MELALUI PENGGUNAAN PUPUK ORGANIK TERHADAP PRODUKTIVITAS PADI (Oryza sativa L.) PADA SISTEM TANAM SRI

The study of influence organic manure to save the fertilizer to get yield of rice (Oriza sativa L.) at system
plant SRI have been conducted at paddy soil at Manggindo Jorong Sangkir Kenagarian Lubuk Basung Province
West Sumatra in the year 2009. Target was to get measuring fertilize able to be economized by using organic
manure to increase result of rice field paddy in conducting of SRI. Attempt used Complete Random Design (RAL),
with treatment of comparison of thrift of usage of fertilizer with addition of organic manure 6 treatment and 4 times
restating, so that there were 24 attempt plot. As for fertilizer and organic manure which used in this research [is] :
200 kg/ ha Urea, 100 kg / ha SP-36, 50 kg / ha MOP and 10.000 Sink / ha Compost hay + cage manure ( v / v). The
treatment [is] : 100% Manure Made in without organic manure ( A); 100% manure made in + 100% organic manure
( B); 75% manure made in + 100% organic manure ( C); 50% manure made in + 100% organic manure ( D); 25%
manure made in + 100% organic manure ( E); and 100% organic manure without manure made in ( F). Data of analysis variance, if F [count/calculate] bigger than real F level 5% continued with Test of Duncan New Method of
Range Test ( DNMRT) [at] real level 5% by using a program of SPSS 15. Perception, for example, is a. High [of] crop,
Amount of tillering per clump, Amount of productive tillering per clump, Amount of productive tillering, length panicles, Amount of shell of rice per malai,. Amount of shell of rice of bernas per malai, wight 1000 seed, dry
Production shell of rice per plot and per hectare. Best result obtained from treatment with [gift/ giving] of manure
made in 100% with organic manure 100% with a production rate of grain dry equal to 5, 05 ton / Ha. Boundary thrift
of usage of manure made in with the addition of organic manure able to be lenient by paddy of IR42 to obtain get a result of maximal [at] this research [is] treatment that is 25% manure made in + 100% organic manure.
