Abstract
ABSTRAK
Penelitian pengaruh jarak tanam dan pemberian pupuk kascing terhadap pertumbuhan dan produksi padi gogo (oryza sativa L) dilaksanakan di Sei Rumbio Kecamatan Kuantan Tengah Kabupaten Kuantan Singingi. Penelitian bertujuan mengetahui pengaruh jarak tanam dan pemberian pupuk kascing secara interaksi. Penelitian menggunakan Rancangan Acak Kelompok factorial terdiri dari 2 faktor . Faktor Pertama J (jarak tanam) terdiri dari 3 taraf perlakuan yaitu: J1 (15 cm x 15 cm), J2 (20 cm x 20 cm) dan J3 (25 cm x 25 cm). Faktor kedua K (pupuk kascing ) yang terdiri dari 4 taraf perlakuan yaitu K1 ( 250 gr/tanaman), K2 (500 gr/tanaman), K3 (750 gr/tanaman), dengan demikian terdapat 12 kombinasi perlakuan terdiri dari 3 ulangan sehingga terdapat 36 plot. Parameter yang diamati tinggi tanaman (cm), jumlah anakan (batang), jumlah anakan produktif (batang), umur berbunga (hari) umur panen (hari), berat gabah/rumpun (gram). Hasil penelitian menunjukkan bahwa perlakuan jarak tanam dan pemberian pupuk kascing secara interaksi berpengaruh nyata terhadap jumlah anakan, jumlah anakan produktif dan berat gabah per rumpun. Perlakuan terbaik pada J1K2 ( jarak tanam yang ke 2 = 15 cm x15 cm, dengan dosis pupuk kascing
500 gr/tanaman). Sedangkan perlakuan jarak tanam secara tunggal berpengaruh nyata terhadap tinggi tanaman, jumlah anakan, jumlah anakan produktif, umur panen dan berat gabah per rumpun,
perlakuan pemberian pupuk kascing yang terbaik adalah K2 (500 gr/tanaman).

ABSTRACT
The research of the effect of planting space and worm feses on growth and productivity of upland rice (oryza sativa L) were conducted in Sei Rumbio, Kuantan Tengah district, Kuantan Sengingi Regency.The objective this research were to know the effect of planting space and worm feses and that interaction on growth and productivity of upland rice (oryza sativa L). The research consisted of
3 levels are : J1 (15 cm x 15 cm), J2 (20 cm x 20 cm) dan J3 (25 cm x 25 cm). second factor were K (worm feses ) that consisted 4 level that are K1 ( 250 grs/plant), K2 (500 grs/plant), K3 (750 grs/plant). So that have 12 treatments combinationand 3 replications, total are 36 plots. Parameters in this research were plant height (cm), tiller numbers, productive tiller numbers, flowering age (days), harvest age (days), weight grains /clump (grams).The result showed that planting space, feses of worm and that interaction weresignificant effect on tiller numbers, numbers of productive tiller and weight of grains per clump. The best treatment combination were J1K2 ( planting space = 15 cm x15 cm and worm feses 500 grs/plant). However planting space have significant effect on plant height, tiller numbers, productive tiller numbers, harvest age and weight of grains/clump. In single treatment, the best dosage of worm feses were K2 (500 grs/plant).
