Title

Diversity of Functional Soil Microbes in Manures and Its Effect on Organic Mustard Green (Brassica juncea) Production Kurniawati, Ari; Melati, Maya; Aziz, Sandra Arifin; Purwono, Purwono

The application of organic fertilizer, especially manures, for crop production has long-term effects for soil nutrients availability and improvement of soil structure. The improvement of soil properties involves interactions of various types of microorganism in the soil. The research aimed to study the effects of different types of manures on the diversity of functional soil microbes and its effects on organic green mustard production. The experiment was conducted at IPB organic research field, Cikarawang, Darmaga, Bogor, from April to June 2015. The experiment used a randomized complete block design with two factors; the first factor was types of manure, i.e. chicken, cow, and goat manures; the second factor was manure rates, i.e. 0 and 10 ton.ha-1, so there were six treatments in total, replicated three times. The results showed that chicken manure application resulted in a higher mustard green yield and soil-P content than application of goat manure. The addition 10 ton.ha-1 of manures increased C-organic, N, K, and C/N ratio in soil significantly, but mustard green production was not affected. The diversity of microbe population of the soil treated with all types of manures was high. The addition 10 ton.ha-1 of manures decreased the total number of microbes, but increased the number of cellulose-degrading microbes. The population of cellulose-degrading and phosphate-solubilizing microbes in the soil applied with cow manure was higher than those applied with the other manures.

Potassium Sources and Rates for Drip Irrigated Polyethylene Mulched Chilli Pepper Hamdani, Kiki Kusyaeri; Susila, Anas Dinurrohman; Purwono, Purwono; Suketi, Ketty

Fertigation with drip irrigation is one of the technologies to solve fertilization and irrigation problems in chilli pepper production using polyethylene mulch. Potassium (K) is one of the important macro nutrients that affect plant growth and development due to its roles in the biochemical and the biophysical processes in plants. The objective of this study was to determine the best sources and the optimum rates of potassium for drip irrigated polyethylene mulched chilli pepper field production. The study was conducted in January until July 2018 at Tajur Experimental Farm, Center for Tropical Horticulture Study, Bogor Agricultural University. The experimental design was a split plot with the K sources (KCl, ZK, NPK) as main plots and K rates that consisted of five levels (0, 68, 136, 204, 272 kg K2O. ha-1) as sub-plots. The results showed that the best optimum rate of K to produce fruit is 101.11 kg K2O.ha-1 with a maximum yield of 2.26 t.ha-1. Chilli crops fertilized with NPK and KCl had the greatest fruit weight per plant, fruit weight per plot, and fruit weight per hectare.

Chilli pepper is the one of most important vegetable crops in Indonesia, and nitrogen is an essential macronutrient ‎to support plant growth. This study was conducted to determine the best source of nitrogen (N) and its optimum rate ‎for drip irrigated polyethylene mulched chilli pepper at. The study site is located at ‎‎ Tajur II ‎Experimental Field of Center for Tropical Horticulture Studies Bogor Agricultural University, West Java, Indonesia, 250 m above the sea level (-6.6364580S, 106.8231460E) from January to August 2018. The experiments were organized in a factorial split-plot with sources of‎ N fertilizer as the main plots (Urea, ‎NPK, and ZA) and rates of N as a sub-plots (0, 115, 230, 345, and 460 kg.ha-‎‎1). The ‎results showed that NPK fertilizer had the best source of N compared to ‎other sources. The maximum yield of 9.01 kg per plot, or equivalent to ‎10.46 t.ha-1, was obtained with N fertilization at 265 to 295 kg.ha-1.‎
