Winged bean (Fabaceae) is a tropical crop that has high nutrient content, and almost all parts of the plant are edible. The research aimed to evaluate the growth and production of winged bean in an intercropping system with tomato. The study was conducted at the Cikabayan Experimental Field of Bogor Agricultural University, Bogor, Indonesia, in a randomized block design with three replications during the rainy season of December 2017 to June 2018. Winged beans were planted in high and low population densities and intercropped with three tomato genotypes, “Tora”, F70030081-12-16-3 and “Apel Belgia”. Monoculture winged bean was assigned as control. Tomatoes were planted between the rows of the winged beans in the intercropping treatment. The results showed that the growth of winged bean in monoculture and intercropping systems was not significantly different. The photosynthetic activity of winged bean at three to five weeks after planting remained high, indicating that the vegetative growth was optimal in both systems. Intercropping increased the winged bean number of pods per plant by 12.66-19.52% compared to monoculture, irrespective of population density. Therefore, winged bean could be considered as suitable to grow in intercropping systems.

<p>Perkembangan varietas-varietas bawang merah di suatu daerah ditentukan oleh keserasian dengan lingkungan, potensi hasil, toleransi terhadap serangan organisme pengganggu tumbuhan (OPT), serta umur dan mutu hasil. Penelitian bertujuan untuk menguji penampilan beberapa klon bawang merah dan hubungannya dengan intensitas serangan OPT penting. Penelitian dilaksanakan di Brebes dan Tegal (Jawa Tengah) dari Bulan Juni sampai dengan September 2011. Perlakuan yang diuji ialah 10 klon bawang merah hasil silangan tahun 2004 dan 2005, serta dua varietas bawang merah sebagai pembanding (Bauji dan Bima Brebes). Rancangan percobaan yang digunakan ialah acak kelompok dan diulang tiga kali. Parameter yang diamati ialah pertumbuhan tanaman (tinggi tanaman, jumlah daun, dan jumlah anakan), hasil panen, dan serangan OPT penting. Hasil penelitian menunjukkan bahwa klon no. 2005/1 dapat beradaptasi dengan baik di Brebes dan Tegal, mampu menghasilkan produksi tertinggi masing-masing sebesar 9,95 dan 17,50 t/ha, mempunyai diameter umbi terbesar (1,87 dan 2,41 cm), bentuk umbi bulat, dan berwarna merah tua, sedangkan klon no. 2004/11 mempunyai pertumbuhan dan  produktivitas yang tinggi, relatif toleran terhadap serangan Spodoptera exigua, Alternaria porri, dan Colletotrichum gloeosporioides, diameter umbi (1,67 dan 1,96 cm), bentuk umbi bulat,  dan berwarna merah tua, sedangkan klon no. 2004/10 dan no. 2005/19 sangat rentan terhadap serangan hama S. exigua, penyakit A. porri, dan C. gloeosporioides. Klon-klon yang mempunyai tingkat serangan rendah/toleran terhadap OPT merupakan klon harapan bawang merah toleran/tahan OPT. Namun demikian, penggunaan pestisida sesuai dengan konsep pengendalian hama terpadu (PHT) masih tetap diperlukan terutama apabila serangan OPT tersebut mencapai ambang pengendalian yang ditetapkan.</p><p> </p><p>The development of shallots varieties in one location depends on the genetic adaptability, yield potential,  tolerance to pest and diseases, harvest date, yield and quality. The aim of study was to evaluate 10 clones and two local clones as check, Bima Brebes and Bauji were conducted in Brebes and Tegal (Central Java) from June to September 2011. The trial were laid out in a completely randomized block design and each treatment was replicated three times. The parameters used for evaluating these clones were plant height, no. of sprout,  no. of leaves, yield and pests and diseases incidence. The results showed that considering overall performance, clone no. 2005/1 gave the highest yield (9.95 and 17.50 t/ha), and diameter of bulb (1.87 and 2.41 cm) in Brebes and Tegal respectively, clone no. 2004/11 produced growth and good yield  and showed tolerance to Spodoptera exigua, Alternaria porri, and Colletotrichum gloeosporioides, bulb diameter (1.67 and 1.96 cm) with dark red color,  while clone no. 2004/10 and no. 2005/19 were identified as the most susceptible clones to S. exigua, A. porri, and C. gloeosporioides. This suggests that some of shallots clones could be good candidates for the new varieties of shallots. However, the use of pesticides in IPM concept were still needed especially if the incidence of pests and diseases reach the action threshold.</p>

Aim: To determine the effect of integrated use of inorganic phosphorus along with phosphorus solubilising bacteria and farmyard manure on nutrient Content and uptake in Bt-Cotton. Study Design: The experiment was laid out in randomized block design with three replications. Place of Study: At College Farm, Agricultural College, Bapatla, Guntur district. Methodology: After the preliminary layout, the Tulasi-BG II hybrid of cotton was used as a test crop, with a spacing of 90 cm x 60 cm in the experimental site. Plant samples were collected at 45, 90 DAS, and harvest. Plant samples were shade dried and kept in hot air oven at 75°C until a constant weight was obtained. Samples were powdered and then analysed using standard chemical procedures. Results: The uptake of macronutrients viz., N, P, and K was markedly influenced by the treatments with maximum values recorded by the treatment that received 60 kg P2O5 ha-1 + FYM + PSB. Their uptake significantly differed with increase in dose of phosphorus applied at all growth stages. Combined use of 60 kg P2O5 ha-1 + FYM + PSB resulted in a significant increase in uptake of all micronutrients (Zn, Cu, Mn, and Fe) at all stages except Cu at 90 DAS. Conclusion: Application of phosphorus combined with FYM and PSB not only reduce inorganic phosphorus fertilization but also enhance the uptake of nutrients and plant nutrient content by providing favourable conditions for plant growth. Application of 30 kg P2O5 ha-1+ PSB + FYM was found to be on a par with addition of only 60 kg ha-1P2O5. Hence the P dose can be reduced to half by integrating with PSB and FYM.

Standardized preparations of yeast and vitamin B12, and some alternative treatments, were administered to Indian fresh-water carp (Catla catla, Labeo rohita, Cirrhina mrigala) during the first 2 weeks of life following hatching, to determine their effect on survival.A randomized block design was employed to set up 54 treatment groups, with 9 replications for each of 6 treatments. The daily treatments per 9 liters of water were: 0.324 g yeast; 25 μg crystalline vitamin B12; 10 ml of ruminant stomach extract; 1 μg cobalt nitrate; 10 ml ruminant stomach extract with 1 μg cobalt nitrate; and an untreated control. Significant differences (P < 01) were observed between the proportion of carp surviving in the control and in treatments with yeast, vitamin B12, ruminant stomach extract, and ruminant stomach extract with cobalt nitrate. Yeast was the most effective treatment, with 89% surviving; with ruminant stomach extract with cobalt nitrate 84% survived; with ruminant stomach extract alone 83% survived; with vitamin B12 75% survived; while 65% survived in the untreated control. The results indicate that some components of the vitamin B complex, including B12, are effective in increasing survival during the early period of life. Alternative treatments utilizing ruminant stomach extract, possibly containing these components, are also adequate for increasing survival.

The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9.8% as compared to chemical treatment. T4 was also more efficient than T5 because it uses less biological agents. The advantage of biological agents is compatible if they were used together with predators such as Oxyopes sp., Paederus sp. and Coccinella sp; and also Telenomus sp. and Trichogramma sp. parasitoids. On the other hand, the chemical pesticides (T6) killed all existing natural enemies. Therefore, T4 could be recommended for controlling mungbean pests and diseases.

Response of Salak Seedlings (Salacca Zallaca) Growth to Dosage of Endomycorrhizal Spore in Quartz Sand and Zeolite Carrier Media. This study aimed to study the effect of endomycorrhizal spore dosage and carrier media that were applied directly to the roots of salak plants. The research designed as factorisl by using Randomized Block Design with 2 treatment factors. The first factor was number of endomycorrhiza spores consists of 4 levels i.e 0, 75, 150, and 225 spores per 500 g carrier media per polybag, while the second factor was the type of carrier media consist of 2 levels i.e zeolite and quartz sand. The results showed that interaction between endomycorrhizal spore dosage with   carrier   media   did   not   significantly   influence   the   growth   of   salak   seedlings. Endomycorrhizal spores in doses of 75, 150 and 225 spores per polybag increased root infection and leaf P nutrient content compared to control, but seed height, leaf area, shoot dry weight, root dry weight and total dry weight of seedlings not significantly difference. The zeolite carrier media caused root infection by mycorrhizal was higher than quartz sand media, but the P nutrient uptake and seedling growth were not significantly different. Based on the results of this study it is necessary to make a longer observation of the effect of endomycorrhizal spore doses and carrier media on the growth of salak seedlings.

The field experiments were conducted in farmer's field at five locations each of kole lands to study the effect of Magnesium (Mg) on yield and soil and plant nutrient status of rice during 2012-2013 and 2013-2014. The experiment was laid out in randomized block design with three replications. The treatments comprised of different levels of Mg viz; 40, 60, 80, 100, and 120 kg Magnesium sulphate(MgSO4)/ha along with control. Observations on growth characters yield attributes, yield and soil and plant nutrient status were recorded. The results revealed that application of 100 kg MgSO4 / ha recorded the maximum number of panicles/m2 (419.13), number of grains/panicle (109.36), thousand grain weight (28.78 g), grain (9.27 t/ha) and straw yield (9.04 t/ha) of rice. The results of pooled data on plant and soil nutrient status revealed that application of magnesium had a positive effect on nutrient content and availability of nutrients in soil. A significant positive correlation was also noticed between Mg application, yield attributes, yield and nutrient contents. The study concluded that application of 100 kg MgSO4 / ha was found to be optimum for correcting the deficiency in Mg deficient areas of kole lands under below sea level farming.

Soybean (Glycine max (L) Merr.) planted in land space among stands of other crops especially forest trees experience shading stress due to less sunlight penetration. The objective of the study was to identify the performance and yield stability of soybean genotypes in various shading environments. Field research was conducted in 2018 on 15 soybean genotypes consisted of 12 promising soybean lines and three check varieties (Dena 1, Dena 2, and Grobogan) in 10 shading environments (cassava, maize, orange, teak, eucalyptus, oil palm, and no shading). Randomized block design and repeated four times was used in each location. Result of the study showed that the response of the genotypes to grain yield was significantly difference in each environment or location. Stability of genotypes were grouped into 3, namely 1 genotype classified as unstable and recommended for less optimal environments, 6 genotypes (5 promising lines and 1 check variety) which were classified as stable and adaptive in 10 test locations, and 8 genotypes (6 promising lines and 2 check varieties) classified as unstable in 10 test locations. Based on seed yield and yield components average, one line (Grob/Pander-395-2) had a high average seed yield (1.84 tha-1), high seeds weight per plant (14.8 g), high weight of 100 seeds (21.6 g), and stable in 10 location (indicated by non significant both regression coefficient and regression deviation). Therefore, Grob/Pander-395-2 could be recommended for being grown in shading environments across the country.

This research was aimed to describe the yield stability and growth adaptation of elite lines of aromatic rice in rice production centers of North Sumatra. The experiments were conducted at 10 sites during dry season (DS) 2001 and DS 2002. Research materials consisted of 12 elite lines introduced from IRRI with IR64 as check variety. The treatments were arranged in a randomized block design (RBD) with three replications. Stability analysis was performed using methods of Eberhart and Russell, Finlay and Wilkinson, and Francis and Kanennberg. The results showed that the interaction of genotype x environment effect was very significant, indicating the presence of specific line adaptation on a particular environment. Genotypes which had the highest average yield were not always stable genotypes, as was shown by IR71137-49-1-2 which was more suitable to the sub-optimum environment. Lines IR71143-223-3-2-2-3, IR71146-97-1-2-1-3, IR65610-24-3-6-3-2-3, IR66696-49-1-2, IR71146-407-2-1-2-1, IR71146-122-1-1-2-1 were considered as stable genotypes according to the three analysis methods and each line showed high average yield. Those genotypes are suggested to be planted in the high productivity environments in order to obtain its optimum genetic expressivity on grain yield
