PENGARUH AMELIORAN DALAM MENGEFISIENKAN PENGGUNAAN PUPUK P PADA TANAMAN PADI GOGO (Oryza sativa L.) VARIETAS SITU BAGENDIT DI TANAH ULTISOL
Abstract: The research intent
to know ameliorant influence to efficient using of P fertilizers and the best
recommanded for growth and production of upland rice (Oryza sativa L.) Situ
Bagendit variety on ultisol. Research conducted in UPT area of research farm in
faculty of agriculture, Riau University on Bina Widya Campus Km 12,5
sub-district of Simpang Baru, district of Tampan, Pekanbaru from December 2014
until Mei 2015. This research arranged experimentally by using Completely
Randomized Design which consist of 9 treatments and then obtained 27
experimental units with 3 sample each unit. Parameter observed rate of P,
efficient of P absorption, efficient of production gram of grain rice,
ameliorant influence in the efficient to absorp P fertilizer, ameliorant
influence in the efficient to product of grain rice, plant height, productive
tiller number, panicle length, the percentage of pithy grain, 1000 seed weight,
dry of grain weight/family and dry plant of weight. Data were analyzed
statistically using ANOVA and followed by HSD at level of 5%. The result showed
that giving ameliorant be BFA 12,5 g, green manure of krinyuh 12,5 g and green manure
of krinyuh 12,5 g + BFA 12,5 g can give the best result in rate of P, efficient
of P absorption, efficient of production gram of grain rice, ameliorant
influence in the efficient to absorp P fertilizer, productive tiller number,
plant height, dry of grain weight/family and dry plant of weight.
