Abstract

            The objective of study was to determine response of three varieties of rice to timing of providing organic fertilizer on SRI system. The results showed that the timing of providing organic materials exerted a significant effect on grain weight per hill and production per hectare, but no significant effect on variables of other rice growth and production. Provision of organic matter at planting date and a week after planting date gave  better grain weight per hill and production per hectare than a week before planting date. These results were consistent for all the tested rice varieties, i.e. Ciherang, Pandan Wangi, and Angke.  However, to some extent, Pandan Wangi was the best.

Abstract

ABSTRACT             The objective of study was to determine the effective concentration of garlic extract in controlling S. zeamais on maize in storage. Concentrations of garlic extract tested were 2 percent, 4 percent, 6 percent, 8 percent, 10 percent, and 12 percent. The results showed that garlic extracts were potential as plant-based insecticide, indicated by a positive effect of garlic extract on S. zeamais mortality, the average time of S. zeamais death, the maize kernel damage and the number of S. zeamais progeny. Concentration of 12 percent gave the highest mortality rate of S. zeamais, the fastest average time of S. zeamais death, the lowest maize kernel damage and the lowest number of S. zeamais progeny, while the concentration of 2 percent gave the lowest mortality rate of  S. zeamais, the longest average time of S. zeamais death, the highest percentage of kernel damage, and the highest number of S. zeamais progeny.

Abstract

The ojectives of this research were to study effect of media composition and  foliar fertilizer of NOVELGRO concentration on growth Jatropha curcas.  Experimental design used was a factorial 3x4 with three replications. Factors investigated were growth media composition with a ratio of 1:1:1 (soil, compost, sand), (soil, compost, and rice husk), (soil, compost, saw dust), and Novelgro concentration of 0, 1, 2 and 3 cc/L of water.  Results showed that there was a significant effect of growth media composition on plant growth and leaf number  at  35, 45 and 55 day after planting (DAP), stem diameter at 45 and 55 DAP, fresh weight, dry weight and dry weight of root, but the media composition did not show significant  effect on plant growth and leaf number at 25 DAP and stem diameter at 25, 35 DAP. The best growth was found at media composition of soil, compost and sand with a ratio of 1:1:1.  Fertilizer concentration significantly affected stem diameter at 25 DAP but did not show a significant affect on plant growth and leaf number at 25, 35, 45, and 55 DAP, stem diameter at 35, 45, and 55 DAP, fresh weight, dry weight and dry weight of root. Plant growth was best at a fertilizer concentration of 2cc/L of water. There was no significant interaction between growth media composition and fertilizer concentration on all variables observed.

Abstract

ABSTRACT The objective of this study was to evaluate anatomical changes and oligosaccharide content of recalcitrant seed Avicennia marina at various drying rate i.e. fast, medium and slow drying.  Oligosaccharide content was determined, and anatomical embryonic axes was observed at various times during desiccation. The result showed that moisture content of  A. marina seed was 60.75-64.67% at shedding. The highest ratio of (raffinose + stachyose) / sucrose was 0.41, indicating that embryonic axes were more tolerant to desiccation than cotyledon.   Anatomical observation of embryonic axes showed that there was radicle damage due to  medium and slow drying treatment.

Abstract

            Response of plant on agroinputs such as organic fertilizer is different, depending on cultivar. Nutrient composition of organic fertilizer is also varied from one to another. The cultivar of Kipas Putih and Anjasmara were studied. The growth and yield of soybean were significantly affected by cultivar and organic fertilizer,  composted from manure and green manure using EM-4.  The growth and yield of Kipas Putih were significantly better than those of Anjasmara.  Fertilization with 12.5 ton/ha of organic matter also increased growth and yield of soybean.

Abstract

ABSTRACT Study of Biokomplek Trico-G and Inoculation of Rhizobium on soybean yield has been conducted. The aim of research was to evaluate concentration of Biokomplek Trico-G and Rhizobium inoculation on yield.  The experiment used a randomized complete block design 4x2 with 3 replicates. Factors evaluated were concentration of Biokomplek Trico-G, consisted of 4 levels, that is: 0, 5, 10 and 15 g/L water and Rhizobium inoculation, consisted of 2 levels, that is without inoculation and inoculation with ex-soybean soil.  Results showed that the concentration of Biokomplek Trico-G had a highly significant effect on dry weight seed per crop and dry weight seed per hectare and had a significant effect on seed diameter. The best result was concentration of Biokomplek Trico-G at 10 g/L water.  Inoculation of Rhizobium had a highly significant effect on number of productive branches and a significant effect on number of fine pods per crop but insignificant effect on seed diameter, dry weight of seed per crop and dry weight of seed per hectare. The best result was inoculation with ex-soybean soil.

Abstract

            Various forms of soil damage can be seen from the changes in physical properties, chemical and biological soil which happens in almost all coastal areas affected by the tsunami. The objectives of the study were to investigate the influence of organic and inorganic fertilizers in tsunami-affected lands on the growth of lettuce, and elemental content of N, P, and K in soil and plants. Experiment was carried out in polybags. Result showed that organic and inorganic fertilizer increased nutrient status of N and P soil, increased growth and nutrient content of N and P in lettuce plants. While for nutrient content of K, organic and inorganic fertilizer only affected soil and roots of lettuce. Growth and nutrient content of N, P and K in soil and plants due to organic and inorganic fertilizer application was highly dependent on the dosage given. The best growth of lettuce was obtained at combination of organic fertilizer 30 tons/ha with inorganic NPK fertilizer 1000 kg/ha

Abstract

ABSTRACT The purposes of this study were to determine the resistance levels of non-irrigated rice to green bug (Nezara viridula L.) after providing bio-fertilizers and dosages of phosphorus. This research was carried out in the Experimental Farm of Research Center for Agricultural Technology (BPTP) NAD, Banda Aceh. The research applied a completely randomized factorial design with 2 treatments, i.e., 4 dosage levels of bio-fertilizers and 4 dosage levels of phosphorus. The results showed that the percentage of damaged plants, percentage of eating inhibition, and the percentage of infected spikelet showed a significant difference between treatments. The higher the dosages of bio-fertilizers and phosphorus were given, the lesser damage and the greater the eating inhibitions were recorded, and the smaller the grains were broken.
