Effect of prunning technique and foliar fertilizer application had been conducted to improve yield of pecco in the Research Institute for Tea and Cinchona experiment station, Gambung, Indonesia with altitude of 1.350 m above sea level, and with andysol soil type. The experiment was held from July to October 2015 in tea production field area containing 480 plants. The clone was GMB 7and was in the fourth prunning year, interval of plucking pecco was seven days. The experiment was arranged in a randomized block design with four treatments, replicated six times. Foliar fertilizer application was performed following every plucking. The results indicated that breaking apical dominance of tea short by 5 cm–10 cm of prunning above plucking table combined with foliar fertilizer application of N 1% and ZnSo<sub>4</sub> 2% + 0,1% of humic acid, could increase weight of pecco per plot in the first nine weeks of the prunning. This treatment was better than the other three. But the percentage of pecco shoots was low, lower than 50%, the weight of one pecco was also very low 0,7 g, indicating that the treatment of harvesting pecco in the fourth prunning year was not recomended to be practiced in improving yield of pecco.

<p>Buah biwa (Eriobotrya japonica) sangat baik untuk kesehatan tubuh dan dapaat digunakan sebagai bahan baku obat-obatan. Budidaya tanaman biwa di tingkat petani saat ini masih bersifat tradisional, sehingga produksinya masih rendah dan belum dapat memenuhi kebutuhan konsumen. Salah satu penyebabnya ialah keterbatasan informasi mengenai penggunaan pupuk yang efektif dan efisien pada pembudidayaannya. Penelitian bertujuan mengetahui pengaruh pemberian pupuk N, P, dan K pada tanaman biwa. Penelitian dilakukan di Kebun Percobaan Tanaman Buah Berastagi dengan ketinggian tempat 1.340 m dpl., dengan jenis tanah Andisol, yang dilaksanakan dari bulan Januari sampai dengan Desember 2006. Percobaan menggunakan rancangan  acak kelompok pola faktorial dengan dua ulangan. Perlakuan terdiri atas tiga faktor yakni : N (0, 180, dan 360 kg/ha), P (0 dan 36 kg/ha), dan K (0, 180, dan 360 kg/ha). Hasil penelitian menunjukkan adanya  interaksi NxP dan NxK terhadap pertambahan tinggi tanaman pada umur 6 dan 8 bulan setelah pemberian pupuk pertama.Tidak ada interaksi NxP yang nyata terhadap pertambahan diameter batang, namun ada interaksi NxK yang nyata terhadap pertambahan diameter batang pada umur 4, 6, dan 8 bulan setelah pemberian pupuk pertama. Taraf dosis pupuk N:P:K (360:36:180) kg/ha menghasilkan pertumbuhan vegetatif tanaman biwa (tinggi tanaman, diameter batang, serta jumlah tunas) yang lebih baik dari perlakuan lainnya. Hasil analisis daun biwa memperlihatkan bahwa kandungan hara N, P, dan K   terbesar dalam daun yang ditemukan pada perlakuan dosis pupuk N:P:K (360:36:180) kg/ha. Implikasi dari penelitian ini adalah sebagai pedoman pemupukan pada budidaya biwa.</p><p> </p><p>Loquat fruits is very good for human health. Furthermore, it can be used as the raw material for some medicines. Until now the loquat cultivataion is still traditionally practiced by farmers, so its production is still very low and can not fulfill consumers demand. One of the reasons is that the information of effective and efficient fertilization is not available. The objective of the research was to determine the effect of  N, P, and K fertilizers on the growth of loquat. The research was conducted at Berastagi Experimental Fruit Farm, at altitude of 1,340 m asl, with  Andisol soil type, on January to December 2006. A randomized block design was used with two replications. The research consisted of 18 treatments combination with three factors i.e. N (0, 180, and 360 kg/ha), P (0 and 36 kg/ha), and K (0, 180, and 360 kg/ha). The results showed that there were significant interaction effects of NxP and NxK to plant height on 6 and 8 months after the first fertilizer application. The significant interaction effect of NxK was also stem diameter on 4, 6, and 8 months after the first fertilizer application. The  dosage of N:P:K (360:36:180 kg/ha) exhibited better vegetative growth of loquat (plants height, stem diameter, and number of shoots) compared to other treatments. The analysis of loquat leaves indicaated that the content of N, P, and K nutrients on leaves was higher on the fertilizer dosage of N:P:K = 360:36:180 kg/ha  compared to the other fertilizer treatments.Implication of the research is to guide fertilizing on loquat cultivation.</p>

[APPLICATION OF LEAF FERTILIZER TO INCREASE THE GROWTH AND YIELD OF BAWANG DAYAK (Eleutherine palmifolia (L.) Merr)]. Bawang Dayak (Eleutherine palmifolia (L.) Merr) is a potential medicinal plant and required improved growth and yield through the application of appropriate fertilizers. This study aimed to increase the growth and yield of bawang Dayak by determining the optimum concentration and time interval of foliar fertilizer application. The experiment was arranged in a completely randomized block design factorial. The first factor was the concentration of foliar fertilizer, consisting of 0,1, 2, and 3 g/L. The second factor was interval application of foliar fertilizer, consisting of every day, every 3 days, every 6 days, and every 9 days. The results showed that bawang Dayak did not show a significant response to foliar fertilizers. However, there was an interaction between the concentration and interval of foliar fertilizer application which had a significantly different effect on plant height. The highest plant height occurred at intervals of 3-day foliar fertilizer application with a concentration of 3 g/L. The concentration of foliar fertilizer had a significant effect on the variables of plant height, bulb fresh weight, as well as the bulb numbers. All concentrations of foliar fertilizer (0-3 g/L), and time intervals of foliar fertilizer application (1-9 days) affected the same growth and yield response of Bawang Dayak.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

ABSTRACTResistance Test of Potato Clones Derived from Crossing of Atlantic x Repita to Late Blight (Phytophthora infestans)Late blight, incited by Phytophthora infestans is the most destructive disease of potato. The management that is effective and environmentally-friendly is the use of resistant variety. The objective of this study was to test the resistance of the six potato clones (AR 04, AR 05, AR 06, AR 07, AR 08 and AR 09) derived from crossing var. Atlantic x var. Repita to late blight caused by P. infestans. Var. Atlantic, Repita and Granola were used as susceptible, resistant and susceptible but the most-grown variety, respectively. Field test was located in Ciwidey, one of the potato growing center where late blight is endemic since potatoes are continuously grown. The treatments were arranged in a randomized block design with 3 replicates. The result showed that clones AR 07 and AR 08 were more resistant than the other potato clones, but it still below the resistance level var. Repita. However, based on statistical test on the diseases development (AUDPC), clone AR 08 could be categorized as resistant, equal with of the resistance level of var. Repita.Keywords: Potato clones, Rsistance, P. infestansABSTRAKPenyakit hawar daun yang disebabkan Phytopthora infestans merupakan penyakit utama pada tanaman kentang.

Utilization of maize waste as the organic matter sources in agricultural land couldn’t be directly applied, caused by late decomposition prosess. An effort to accelerate of maize waste decomposting needed bioactivator. The research was conducted in green house and Bajeng Research Intallation from March to August 2015. The research was arranged in randomized block design using isolate bacteria and fungus just one or theier combining ie: three bacteria  (B7.1,E7.7and E7.11), three fungus (M7, O5, P7), and four bacteria-fungus combining(B7.1+O5, B7.1+M7, E7.7+P7, B7.1+E7.7+O5), EM4 and N,P,K fertilizer(200,45,60) ha-1as the check treatment. Just one isolate fertilized by 75 percent N,P,K while combine isolate fertilized by 50 percent N,P,K recommended. The results indicated that just one decomposer E7.7 produced high enouugh grain yield not siqnificantly different by N,P,K (200,45,60) and five other just one treatment (E7.11,B7.1,M7 and O5), however siqnificantly different with combining decomposer (B7.1+O5, E7.11+M7, E7.7+P7, B7.1+E7.7+O5 and EM4). This mean that using stalk plus leaf waste maize compost could be subtitution in organic fertilizer untill 25 percent. Meanwhile combining decomposer was good enough for composting stalk and leaf of maize waste ie. isolate B7.1+O5 and E7.7+P7 although not significntly different with the other combine isolate including EM4. Thise case related by applied 50 percent N,P,K inorganic recommended fertilizer did not sufficient to supporting maize nutrient.Key Words: Decomposer, Bacteria, Fungus, Composting,Maize waste

It was evaluated by the Cornell System carbohidrates fractions and nitrogenous compounds of the following grasses at the cutting ages of 14, 28, 42, and 56 days: nilo grass (Acroceras macrum), angola grass (Brachiaria purpurascens), aleman grass (Echinochloa polystachya), limpo grass (Hemarthria altíssima), setaria grass (Setaria anceps), tanner grass (Brachiaria arrecta), and tifton-85 grass (Cynodon spp). The experiment was carried out in a complete randomized block design, in a split plot arrangement in a way that the grasses were evaluated in the plots and the ages of cut in the split-plots. The age of cutting had an effect on the composition of the studied grasses. In most of the grasses, total carbohydrate levels, non-fibrous carbohydrates and A+B1 fraction carbohydrates increased linearly according to the age of cutting. The potentially degradable fraction of carbohydrates (fraction B2) showed a quadratic behavior according to the cutting ages for all grasses. The C fraction of the carbohydrates in tifton-85 grass linearly increased with the age but it did not increase significantly for the other grasses. In setaria grass, the intermediate levels of B2 and B3 nitrogenous fractions were high, which might represent a potential source of protein for ruminal degradation and for the small intestine. Except for setaria grass, all studied grasses show similar values of the A, B1, B2 and B3 nitrogenous fractions.
