Abstract

The aim of the research was to investigate the application of plant compost on the growth and yield of tomatoes. The experiment was conducted in Bandar Lampung from October 2009 until February 2010. The experimental design was completely  randomized block design with 3 replications. The treatments were: control; recommended inorganic fertilizers 135 kg N ha-1, 75 kg P2O5  ha-1, and 110 kg K2O  ha-1; white leadtree (Leucaena glauca) compost + recommended inorganic fertilizer; legume compost + 50% recommended inorganic fertilizer; teak (Tectona grandis) compost + recommended inorganic fertilizer; teak compost + 50% recommended inorganic fertilizer; paddy straw (Oryza sativa) compost + recommended inorganic fertilizer; paddy straw compost + 50% recommended inorganic fertilizer; rattlepod (Crotalaria anagyroides) compost + recommended inorganic fertilizer; rattlepod compost + 50% recommended inorganic fertilizer. Our results showed that rattlepod and paddy straw composts gave similar results in tomato growth and yield, and they were better than other plant composts tested. The application of 50% inorganic fertilizers combined with plant compost had the higher yield as compared to recommended inorganic fertilizer treatment. This implied that the use of plant compost could reduce the use of inorganic fertilizers while maintaining higher yield than using inorganic fertilizers only. The soil chemical properties was improved after application of plant compost.     Keywords: inorganic fertilizer, plant compost, tomatoes

Abstract

A study was carried out to determine the effect of  1-MCP applied to intact tomatoes differing in maturity stage on quality of stored tomato slices.  1-MCP (1 mL L-1, 20 °C, 12 h) was applied directly to intact tomatoes from ‘turning’, ‘pink’, and ‘light-red’ stages of maturity. After slicing, slices were stored for up to 10 days at 5 ºC. 1-MCP maintained slice quality during storage following treatment of intact ‘turning’ and ‘pink’ maturity fruit as indicated by higher titratable acidity, higher ascorbic acid concentration, and lower lycopene content.1-MCP treatment did not significantly affect soluble solids and electrolyte leakage.  Slices from ‘light-red’ maturity stage fruit did not respond to 1-MCP.  The results show that application of 1-MCP to intact tomatoes was effective in maintaining tomato slice quality if 1-MCP is applied to fruit at early (‘turning’ and ‘pink’) stages of maturity.   Keywords:  1-methylcyclopropene, soluble solids, acidity, ascorbic acid, lycopene, electrolyte leakage

Abstract

The objective of this research was to study the effect of bokashi livestock on the growth and yield of tomatoes. The experiment was conducted in Bandar Lampung from October 2009 until February 2010. The experimental design was randomized complete block design with 3 replications. The treatments were: control; inorganic fertilizers at a recommended rate of (kg ha-1) 135 N, 75 P2O5, and 110 K2O (RR); chicken manure bokashi + RR; chicken manure bokashi + 50% RR; cow manure bokashi + RR; cow manure bokashi + 50% RR; sheep manure bokashi + RR; sheep manure bokashi + 50% RR; horse manure bokashi + RR; horse manure bokashi + 50% RR. Each bokashi treatment was applied at the rate of 20 ton ha-1. The result of experiment showed that chicken manure bokashi was the best among bokashi livestock. The application of 50% RR combined with chicken, cow, sheep or horse manure bokashi gave a higher yield than treatment with inorganic fertilizer at recommended rates. These results demostrated that the application of bokashi livestock could potentially reduce the use of inorganic fertilizers while maintaining higher yield.

Abstract

The aim of research was to determine the effect of the combination of a single inorganic fertilizers and biofertilizers on the growth and yield of sweet corn (Zea mays Saccharata Sturt) and soil microbial population. Research was conducted in Bandar Lampung from December 2015 to March 2016. The study was conducted using a randomized block design with six treatments and three replications. Those treatments were K0 (control), K1 (Urea 300 kg / ha, SP-36 150 kg / ha, KCl 100 kg / ha), K2 (Urea = 300 kg / ha, SP-36 150 kg / ha, KCl 100 kg / ha) + Biomax Grow, K3 (Urea 180kg / ha, SP-36 to 90 kg / ha, KCl = 60 kg / ha) + Biomax Grow K4 (Urea 60kg / ha, SP-36 30 kg / ha, KCl 20 kg / ha) and K5 = Biomax Grow. The experiment showed the highest production of sweet corn obtained was 13.20 tonnes / ha from a combination of 60% inorganic fertlizers with biofertilizer.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui apakah pupuk cair urine sapi dapat mengurangi penggunaan Urea dalam upaya untuk meningkatkan pertumbuhan dan produksi jagung manis. Penelitian ini dilakukan di Bandar Lampung. Mulai April sampai Juli 2015. Penelitin  menggunakan rancangan acak kelompok dengan lima perlakuan, yaitu (P0) kontrol, (P1) pupuk Urea 270 gram, (P2) urine sapi 7 ml/l (7.000 ppm) pada 2, 4, 6, dan 8 MST, (P3) pupuk Urea 135 gram dan urine sapi 7 ml/l (7.000 ppm) pada 3 dan 5 MST dan (P4) pupuk Urea 135 gram dan urine sapi 7 ml/l (7.000 ppm) pada 2, 4, 6, dan 8 MST.  Hasil penelitian menunjukkan bahwa pupuk cair urine sapi  memberikan pengaruh nyata terhadap variabel pertumbuhan dan produksi tanaman jagung manis.  Perlakuan P2 pada 2, 4, 6 dan 8 MST direkomendasikan sebagai pupuk alternatif Urea.
