Pengaruh Abu Sekam Padi Dan Pupuk Kandang Sapi Terhadap Pertumbuhan Dan Hasil Tanaman Jagung Manis (Zea mays Saccharata) Pada Tanah Gambut

Abstrak

This study used a completely randomized design (CRD), with a factorial pattern, the treatment consisted of 2 factors, namely: the first factor was Rice Husk Abu with code A, consisting of 3 treatment levels, namely: a0 (0 gram/plant), a1 (60 gram/ plant) and a2 (80 gram/plant). The second factor is cow manure with code S, consisting of 3 treatment levels, namely: s1 (400 grams/plant), s2 (800 grams/plant) and s3 (1,200 grams/plant). Each treatment was repeated 3 times and each repetition consisted of 3 plants. The variables observed in this study were plant height (cm), number of leaves (strands), cob diameter without husks (cm), cob weight without husks (grams), number of cob rows, cob length (cm). The results showed that there was an interaction effect of rice husk ash and cow manure on the growth and yield of sweet corn (Zea mays Sacharata S.) on peat soil, namely the weight of cobs without husks. In the single factor, cow manure had a significant effect on plant height, number of leaves, diameter of cob without cob and cob length without cob, and had a very significant effect on cob weight without cob. Then the analysis of diversity in the single factor of rice husk ash had a significant effect on the number of rows of sweet corn plants. The a0s3 treatment gave the highest average for the variable plant height (203.78 cm), cob length without cob (20.10 cm), while the a2s3 treatment gave the highest average for the variable number of leaves (10.56 strands), cob diameter without cob (5 .41 mm), the weight of the cobs without cobs (354.44 grams) and the number of rows on the cob (15.78)
