Abstract

ABSTRACT Response of rice to paclobutrazol (PBZ) depends on plant variety. This experiment were done to know the influence of PBZ to growth and yield of local rice Wesel using randomized block design (RBD). The treatment consist of four dosages of PBZ with four replications. The results showed PBZ treatmant enhance of grain yield per plant, number of productive tillers (NPT),  weight of 1.000 grains, crop growth rate (CGR), and leaf chlorophyll content.Keywords: Paclobutrazol (PBZ), crop growth rate (CGR), chlorophyll, yield, local rice

Abstract

Tailing is a type of waste produced by mining activities and is characterized by very low physical, chemical, and biological fertility, requiring efforts to amend its quality. The addition of organic materials as a soil ameliorant is one such effort of amendment to enhance success in rehabilitating these degraded areas. The aim of this study is to measure the effects of ameliorant on the growth and yield of sweet corn, determine dosage that will give the best growth and yield, and find out if residual mercury exists in the resultant sweet corn crop. This study used a randomized block design with 6 treatments: A= 40 tons/ha of organic fertilizer; B2= 50 tons/ha of organic fertilizer, C = 60 tons/ha of organic fertilizer, D = 40 tons/ha of organic+ fertilizer, E = 50 tons/ha of organic+ fertilizer, F = 60 ton/ha of organic+ fertilizer. The organic fertilizer used was a mix of 50% water hyacinth + 50% chicken manure, while organic+ fertilizer was a mix of 20% water hyacinth + 20% cow manure + 20% chicken manure + 20% traditional market waste + 20% rice straw. Every treatment was replicated four times, resulting in 24 experimental pots. Variables observed were: 1) cob length, 2) cob diameter, 3) cob weight. Data was analyzed using ANOVA and Tukey’s HSD at a test level of 5%. Results show that organic+ fertilizer increases the yield of sweet corn. A dosage of 60 tons/ha gave the best cobs with a weight of 199,89 grams per cob.

Abstract

Abstrak Tujuan penelitian ini mengkaji pengaruh zat pengatur tumbuh paklobutrazol (PBZ) terhadap kualitas bunga cengkeh (Syzygium aromaticum (L) Merr dan Perry). Perlakuan PBZ terdiri dari empat dosis, yaitu: 1). 0,0 g PBZ/phn/thn (kontrol), 2).  1,0 g PBZ/phn/thn, 3). 1,5 g PBZ/phn/thn, dan 4).  2,0 g PBZ/phn/thn. PBZ dilarutkan ke dalam 220 ml air mineral lalu disiram di tanah di bawah proyeksi tajuk tanaman. Hasil penelitian menunjukan bahwa PBZ mampu: 1)  meningkatkan ukuran panjang bunga dari 3,95% sampai 15,70%, 2) meningkatkan diameter bunga kering dari 6,52% sampai 14,58%, 3) meningkatkan jumlah bunga per tandan dari 4,91% sampai 72,50%, 4) meningkatkan berat cengkeh 1.000 butir bunga kering dari 10,28% sampai 23,88%, tetapi sesudah itu menurun menjadi  20,99%, 5) meningkatkan hasil bunga kering per pohon dari 37,22 % sampai 136,85 %. Secara keseluruhan, PBZ meningkatkan kualitas bunga cengkeh. Kata kunci: cengkeh (Syzygium aromaticum (L) Merr dan Perry), hasil, kualitas bunga, paklobutrazol (PBZ), Abstract The aim of this research was to evaluate the effect of growth hormone paclobutrazol (PBZ) on the flower quality of clove (Syzygium aromaticum (L) Merr and Perry). The treatment was the dosage of PBZ and consisted of 1) 0,0 g PBZ/tree/year (control), 2) 1,0 g PBZ/tree/year, 3) 1,5 g PBZ/tree/year, and 4) 2,0 g PBZ/tree/year. PBZ was diluted in 220 ml mineral water, then drenched to the soil next to the clove stem. The results showed that PBZ was able to enhance 1) the dry flower length as much as 3,95-15,70%. 2) the diameter of dry flower (6,52-14,58%), 3) the amount of flower per inflorescence  (4,91- 72,50%, 4) the weight of 1.000 dry flower (10,28-23,88%) followed by the decline of 20,99 %, 5) the yield per plant as much as  37,22-136,85 %. PBZ enhanced the quality of clove flower. Keywords: clove (Sysygium aromaticum (L) Merr dan Perry), flower quality, paclobutrazol (PBZ), yield.
