<p><strong>The effect of living post and pepper vines primings on the pepper yield</strong></p><p>To obtain good yield of pepper, farmers fequently apply various treatments to their crops, including pruning of the pepper vines and or their living post. Studies on the aspects of the pruning ae however very limited. Therefore a ield experiment was conducted to investigate the effects of pruning of pepper vines and their living post on the pepper yield. The experiment was carried out at Sukamulya Research Station, Sukabumi. A split plot design with three rcplicaties was used. The main plot was the pruning of living post, and the sub plot was the pruning of pepper vines Plot size was 20 plants per plol wilh spacing of 2.5 m x 2.5 m Results showed that there was signiicant interaction between the pruning of living post and pepper vines. The pruning of living post may be carried out either 3 times (October, January and April) or twice (October and January) a year. However. If the pruning of the living post is carried out 3 times per year, Ihe vine would be pruned once a year or not at all. On the other hand, if the pruning of living post is carried out twice a year, the pepper vines would be pruned 6 times a year.</p>

<p>Perbanyakan karet (Hevea brasiliensis Muell. Agr.) dengan okulasi cokelat membutuhkan waktu yang lama dalam pembibitannya, sedangkan perbanyakan dengan okulasi hijau belum banyak dilakukan karena tingkat keberhasilan masih sangat rendah. Salah satu faktor yang diduga berpengaruh terhadap keberhasilan okulasi hijau adalah umur bibit batang bawah. Tujuan penelitian adalah mengetahui pengaruh perbedaan umur batang bawah terhadap persentase keberhasilan okulasi hijau pada tiga klon karet. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar pada bulan Januari-Desember 2013. Penelitian menggunakan rancangan petak terbagi, tiga ulangan dan ukuran petak 25 pohon. Petak utama adalah jenis klon batang bawah, terdiri dari 3 klon, yaitu K1 = AVROS 2037, K2 = PB 260, dan K3 = GT 1. Anak petak adalah umur batang bawah terdiri dari 4 taraf, yaitu U1 = 4 bulan, U2 = 5 bulan, U3 = 6 bulan, U4 = 7 bulan. Okulasi dilakukan dengan cara membuka kulit batang bawah, kemudian entres dimasukkan ke dalam jendela sayatan hasil pembukaan. Pengikatan sambungan dilakukan dengan menggunakan plastik khusus dengan cara dililitkan dari bawah ke atas. Pengamatan dilakukan terhadap persentase keberhasilan okulasi hijau pada umur tiga minggu setelah okulasi (MSO). Hasil penelitian menunjukkan bahwa keberhasilan okulasi hijau pada tanaman karet dipengaruhi oleh umur batang bawah. Untuk Klon PB 260 dan GT 1, makin tua umur batang bawah sampai maksimum 7 bulan di polybag maka semakin meningkat persentase keberhasilan okulasi, sedangkan pada klon AVROS 2037 belum memperlihatkan perbedaan yang nyata.</p><p>Kata kunci: Hevea brasiliensis, umur batang bawah, klon, keberhasilan okulasi hijau</p><p>Propagation of rubber (Hevea brasiliensis Muell. Agr.) using brown budding need a long time in the nursery, whereas the propagation usinggreen Budding has not yet been done due to the success rate is still very low. One of the factorthat might influence the successfulness of green budding is rootstock age.. The purpose of this study was to determine the effect of different age of rootstock on the percentage of green budding success in three rubber clones. The experiment was conducted at the Pakuwon experimental station (ES), Indonesian Industrial and Beverage Crops Research Institute, from January-December 2013. The research was done using split plot design with three replications, and the plot size is 25 trees. The main plot was the type of clones used for rootstock that comprised of 3 clones: K1 = AVROS 2037, K2 = PB 260, and K3 = GT 1. Meanwhile, the subplots were rootstock age consists of 4 levels, namely: U1 = 4 months, U2 = 5 months, U3 = 6 months, U4 = 7 months. Observations were made on the percentage of green budding success at 3 weeks old after grafting . The results showed that the success of the green budding on the rubber plants is influenced by the age of rootstock. The use of rootstock up to 7 months old in polybag in PB 260 dan GT 1 clones would increase the percentage of grafting success, whereas AVROS 2037 clone did not show any significant different.</p><p> </p>

To evaluate the effect of plastic film coverage on ex vitro acclimatization of arrow cane (Gynerium sagitatum Aubl.), shoots of “Criolla”,  Martinera” and “Costera” cultivars were in vitro micropropagated in a medium supplied with 6-Benzylaminopurine and half of them were rooted in a medium with 1-Naphtalene acetic acid. Rooted and unrooted shoots were transplanted in a shade house with fog irrigation, into plastic trays (72 clusters per tray), using peat as substrate and half of them was covered with translucent plastic film during 5 days after transplant while the other half was maintained uncovered. The experiment consisted of a three-way factorial arrangement with 12 treatments distributed with a split-plot design where tray coverage was the main plot, cultivars were the split, and rooting condition was the split-plot. Each treatment (36 clusters) was repeated three times for a total of 1296 experimental units. After 40 days in the shade house, the survival rate was calculated, and plant heigth, number of shoots and number of roots data were analyzed by ANOVA (P<0.05) and means were separated by Tukey test (P<0.05). Plant survival was complete (100%) regardless of genotype, rooting, or coverage condition. Transferring plant into uncovered trays statistically resulted in higher levels for plant height, number of shoots, and number of roots. Ex vitro adaptation of micropropagated arrow cane plants without plastic film covers increased plant growth and reduced labor.

A Field trial was conducted at the aerobic rice experimental field of the NationalCereals Research Institute (NCRI), Badeggi, Nigeria (9 ° 04 N and 6° 7 E)in 2007 and 2008 wet seasons to determine the weed competitiveness andperformance of inter Ã¢â‚¬Â and intra‐specific aerobic rice (Oryza sativa L.) varietiesunder seven weeding regimes. The trial was laid out in a split plot designwith the two varieties of rice (NERICA 1 as inter Ã¢â‚¬Âspecific and FARO 46 asintra Ã¢â‚¬Âspecific) assigned to the main plot while seven weeding regimes (hoeweeding at 25, 45, and 65 days after sowing (DAS), 25 DAS, 45 DAS, 25 and45 DAS, application of 3’,3’ Ã¢â‚¬Â dichloropropionanilide /2, 4 – Dichlorophenoxyacetic acid (orizo plus R) by Candel Company Ltd. at 3.5 kg active ingredient(ai )ha Ã¢â‚¬Â1 at 25 DAS, hoe weeding at 25 DAS followed by orizo plus at 3.5 kg aiat 45 DAS and weedy check) constituted the sub – plots. The treatmentswere replicated three times in a split plot design. From the results, interspecificvariety (NERICA1) had better weed suppression ability with highergrain yield of 3.1 t ha Ã¢â‚¬Â1 than the intra‐specific variety (FARO 46). Weed controlwas better when hoe weeding was done at 25, 45 and 65 DAS or 25 and45 DAS and at 25 DAS followed by orizo plus at 45 DAS than in other treatments.However, hoe weeding at 25, 45 and 65 DAS gave significantlygreater grain yield than other treatments. Although economic yield was obtainedfrom hoe weeding at 25 DAS followed by orizo plus at 45 DAS.

Weed Removal

Field experiment was conducted in 2019 at Haskell Agriculture Laboratory, Concord, NE, USA. Goal of the study was to test the influence of PRE-EM herbicides on the Critical Time for Weed Removal (CTWR) in dicamba-tolerant soybean. The study was arranged in a split-plot design which consisted of four herbicide regimes as main plot treatments and seven weed removal timings as subplot treatments, with four replications. The herbicide regimes included: (1) no PRE and glyphosate, (2) acetochlor and dicamba as PRE and glyphosate as POST, (3) acetochlor and dicamba as PRE and glyphosate and dicamba as POST, and (4) acetochlor and fomesafen as PRE and acetochlor, glyphosate and dicamba as POST. The five weed removal times included the V1, V3, V6, R2 and R5, and there were also weedy and weed-free season long plots. By utilizing herbicide regimes, the CTWR was delayed to 632 GDD (until V4 soybean growth stage, 28 days after emergence) for acetochlor and dicamba as PRE and glyphosate as POST, 861 GDD (until V6 soybean growth stage, 32 days after emergence) for acetochlor and dicamba as PRE and glyphosate and dicamba as POST, and 1060 GDD (until R1 soybean growth stage, 42 days after emergence) for acetochlor and fomesafen as PRE and acetochlor, glyphosate and dicamba as POST.

The yield and quality of perennial ryegrass, short-rotation ryegrass–perennial ryegrass mix, oats, millet, maize, rape, kale, pasja and turnips were determined over a 13-week summer period in 1995–96 and 1996–97. The experiment was conducted on the Elliott Research Station in north-western Tasmania (145˚E, 41˚S) and consisted of 2 irrigated and 2 dryland main plots. Within each main plot was a randomised complete block design with 9 forage crop subplots. Where forage is required through the summer, there is little advantage in establishing millet or oats over a spring-sown ryegrass pasture, mainly as the former still require replacement with permanent pasture in the autumn. However, if additional forage is required from late January then turnips are clearly superior to the other forages evaluated in all respects, apart from a low bulb crude protein (CP) content. Turnips responded significantly to irrigation, producing between 15 and 22 kg DM/ha.mm irrigation applied, with yields ranging between 7.9 and 10.6 t DM/ha dryland and between 13.5 and 14.4 t DM/ha under irrigation. The metabolisable energy (ME) and CP contents of turnips were 12.5 MJ/kg DM and 12.4% in the shoots and 13.4 MJ/kg DM and 7.0% in the bulbs, respectively. In comparison, the other fodder crops tested yielded between 4 and 6 t DM/ha under dryland conditions and between 5 and 7 t DM/ha under irrigated conditions. Turnips were most economic, costing on average A$120/t DM irrigated and $160/t DM dryland, while spring renovation to perennial ryegrass cost $385/t DM irrigated and $344/t DM dryland; clearly more expensive than purchased feeds for this period. These findings confirm the choice of many farmers that, of the species examined, turnips are the most suitable as a summer fodder crop, both irrigated or dryland, and integrate well with a pasture renovation rotation.

A field experiment was conducted at Main Agricultural Research Station, Dharwad during rainy season of 2015 and 2016 to study the effect of planting pattern and phosphorus management on production and profitability of intercropping system of mungbean and pigeonpea. The experiment was laid out in split plot design with three replications and eight treatments. Among them, four planting patterns [sole pigeonpea, mungbean + pigeonpea 1:3 (120 cm x 20 cm), mungbean + pigeonpea 1:2 (90 cm x 20 cm) and mungbean + pigeonpea 2:2 (90 cm x 20 cm)] were main plot treatments and two phosphorus levels (P2O5 @ 50 kg ha-1 and P2O5 @ 75 kg ha-1) were sub plot treatments. Based on pooled data the results revealed that, the significantly higher mungbean seed yield (424 kg ha-1) was recorded with application of 75 kg P2O5 as compared to 50 kg P2O5 ha-1. Whereas, in planting pattern, sole mungbean recorded significantly higher seed yield (757 kg ha-1) as compared to all other intercropping systems. Yield advantage indices and net returns were significantly higher in pigeonpea + mungbean (1:3) with 75 kg P2O5 ha-1 as compared to other treatments. This study indicated the need of fifty per cent higher dose of P2O5 for the pigeonpea and mungbean intercropping system (1:3) in northern transition zone of Karnataka.

THE EFFECT OF WHITE TURMERIC (Curcuma mangga Val.) ADDITION ON CHICKEN MEAT AGAINST WATER CONTENT, pH AND MICROORGANISM NUMBERS. The purpose of this research was to determine the effect of the addition of white turmeric (Curcuma manggaVal.) on chicken meat at cold storage (4oC). This research used Split Plot Design with 2 treatment factors based on completely randomized design. The Main Plot contains of 4 treatments (A0 = without storage, A1 = 3 days storage, A2 = 6 days storage, A3 = 9 days storage) and the Sub Plot contains of 4 treatments (B0 = without white turmeric, B1 = 4% grating of white turmeric, B2 = 8% grating of white turmeric, B3 = 12% grating of white turmeric). The variable that observed are water content, pH and microorganism number. The result showed that the addition of white turmeric was not significant affected (P > 0.05) against water contentof chicken meat, however it was highly significant affected (P < 0.01) against pH and microorganism numbers of chicken meat. Storage time was highly significant affected (P <0.01) against water content, pH and microorganism numbers of chicken meat. The interaction between both of treatment factors was given highly significant affected (P < 0.01) against water content, pH and microorganism numbers of chicken meat. As a conclusion, the addition of white turmeric on chicken meat was not affected against water content, however it can decrease pH and obstruct microorganism activity.
