Abstract

This study aimed to find out the effect of bokasi gulma application time and leaf trimming on the production of Sorghum. This research was carried out during period from Desember 2015 to april 2016. The Research conducted in the Public Land on Jalan Penerbangan RT/05 RW/08 Kelurahan Simpang Tiga, Bukit Raya District, Pekanbaru City. The experiment was laid out in a completely randomized design in a 4 x 4 factoria. The First factor was time of bokasi gulma application, consisting og W1. (2 weeks before planting), W2. (planting time), W3. (2 weeks after planting), and W4. (4 weeks after planting). The second factor was the leaf trimming, consisting of T1 (without trimming), T2 (pruning age of 25 days after planting), T3 (trimmed age of 50 days after planting), T4. (trimmed age of 75 days after planting). The parameters observed were the length of panicle per panicle (cm), panicle dry weight per panicle/ plant (g) with water contain by 12%, weight of 1000 seeds per plant (g) and production (water contain by 12%) of dry sorghum per hectare (kg). The best treatment was W2T4 (time of giving bokasi gulma at planting and trimming the leaves when the plants of 75 days after planting) with the results; length of panicle per panicle (19.48 cm), panicle dry weight per panicle/plant of 112 grams KA 12%, weight of 1000 seeds per plant (38.07 grams), and production (KA 12%) of dried sorghum per hectare (6473.52 kg).

Abstract

Maize is the most important food commodity containing carbohydrate at the second rank after rice. Organic agriculture is natural farming which is able to suppress the use of organic material giving negative effect on environment. This research aims to examine the response of giving type and dosage of bokasi on growth and yield of Sweet Corn. The completely randomized design was used with 4 x 4 factors. The treatment used four bokasi type namely: weed bokasi (J1), maize bokasi (J2), coconut waste bokasi (J3), and manure bokasi (J4). While, Bokasi dosage consisted of 10 grams per plant (D1), 20 grams per plant (D2), 30 grams per plant (D3), and 40 grams per plant (D4). The parameters observed were cob length, cob diameter, and cob weight per con. The results showed that the best response of giving type and dosage of bokasi was found on weed bokasi under dosage 10 grams per plant with cob length of 13.70 cm, cob diameter of 4.10 cm and cob weight of 95 grams per cob.
