PEMBERIAN CAMPURAN AMELIORAN (KAPUR KALSIT, PUPUK HIJAU KRINYUH DAN BATUAN FOSFAT ALAM) PADA BEBERAPA VARIETAS PADI GOGO (Oryza sativa L.) DI TANAH ULTISOL
Abstract: The purpose of this
research to investigated influence of ameliorant mixture (calsite lime, krinyuh
green manure and natural rock phosphate) toward some varieties upland rice on
Ultisol soil and get the best ameliorant mixture for increase the productivity
of upland rice. Research conducted in BiologicalControl Community (Biccom)
field, (UPT) research farm in Faculty of Agriculture, Riau University on Bina
Widya Campus Km 12,5 Simpang BaruSub-district, Tampan District, Pekanbaru from
December 2014 till May 2015. This research arranged experimentally using
Completely Randomized Design Factorials consist of 3 levels varieties: Inpago
8, Situ Patenggang and Situ Bagenditand 5 levels ameliorants mixture : K0
(without ameliorant mixture), K1 (24,99 lime g+krinyuh green manure 12,49
g/polybag), K2 (lime 24,99 g + BFA 12,49
g/polybag), K3 (krinyuh green manure 12,49 g+BFA12,49 g/polybag) and K4 (lime
24,99 g+krinyuh green manure 12,49 g+BFA 12,49 g/polybag) and then obtained 15
experimental units with 3 sample each unit. Parameter observed of plant height,
maximum tillering amount, flowering time, penicle length, productive tillering
amount, harvest time, 1000 grain weight, percentage of grain pithy, dried grain
weight, weight dry straw plant and ratio of grain and straw. Resultsanalysis of
