This study evaluated stability, maturity and the efficacy of different poultry litter for possible use in container plant production. Three types of poultry manure- Battery cage (BC), Deep litter (DL) and Free range (FR) were used, with Kraal manure (KM) as a comparison. The experiment was set up as a Split- split design with 6 replications. Composting period was main plot, poultry manure type the split plot and mixing ratio as the split- split plot. The litter was mixed with garden soil in 2 ratios (3:1 and 1:1 soil: manure ratio) and tested for up to 12 weeks. Rape (Brassica napus) was used as a bioassay for maturity, which was determined at 1 month, 2 months and 3 months. The pH declined slightly from 7 to about 6 for all treatments except for the kraal manure. Respiration trends were similar to electrical conductivity. Within 2 weeks of curing the respiration rate for all manures declined to below 4 mg CO2- C/ kg. At the end of 12 weeks curing Battery cage had highest total nitrogen (2.32 %), followed by Free range (1.25 %), Deep litter (0.73 %) and Kraal manure was lowest at 0.35 %). Maturity (rape survival) increased with compositing time. After 3 months of curing Kraal manure had highest survivability of rape. The DL at 1:1 ratio had the lowest survival of 67%. At 12 weeks except for BC at 3:1 all treatments had 100 % survival. The results showed that nitrogen rich manures (DL and BC) needed longer curing in order for them to reach maturity.

Abstract In 2010, a split-plot experiment was set up in Poland in order to determine the follow-up effect of the white clover intercropping system on biomass and morphology of willow. In 2010 willow was planted in a pure stand and intercropped with white clover. In 2013, after willow achieved a proper growth stage (2010–2012), plant measurements were made in the years 2013–2014. The experiment was carried out with two factors in a split-plot design: the first factor was the cultivation system (main plot) (a) without white clover and (b) with white clover, and the second factor was three basket willow clones: 1047, 1052 and 1057 (subplot). The investigated characters were biomass yield, height of plants, shoot diameter and plant loss. No N fertilization or pesticides were used. The intercropping system (willow with white clover) reduced the number of willow plants, but the willow height was lower in the pure stand (368 cm) than in the intercropping system (409 cm). The highest dry matter yield (30.8 t ha−1), crude ash yield (434 kg ha−1) and macronutrient (N, P, K and Mg) content were obtained with clone 1047.

Abstract WholeTree (WT) and clean chip residual (CCR) are potential new nursery substrates that are by-products of the forestry industry containing high wood content. Initial immobilization of nitrogen is one concern when using these new substrates; however the addition of composted poultry litter (CPL) to substrates containing high wood content could balance initial nitrogen immobilization and provide an inexpensive fertilizer source for growers. This study evaluated five woody nursery species being grown in WT, CCR, and pinebark (PB) with the addition of CPL or peat as a substrate amendment. Results indicate that these species can be grown successfully in WT and CCR substrates 6: 1 (by vol) with CPL. Use of CPL in WT and CCR substrates may provide an alternative to traditional PB plus peat based combinations in container plant production while providing poultry producers an environmentally sound means of waste disposal.

Abstract Velvetleaf is an economically important weed in agronomic crops in Nebraska and the United States. Dicamba applied alone usually does not provide complete velvetleaf control, particularly when velvetleaf is greater than 15 cm tall. The objectives of this experiment were to evaluate the interaction of dicamba, fluthiacet-methyl, and glyphosate applied alone or in a mixture in two- or three-way combinations for velvetleaf control in dicamba/glyphosate-resistant (DGR) soybean and to evaluate whether velvetleaf height (≤ 12 cm or ≤ 20 cm) at the time of herbicide application influences herbicide efficacy, velvetleaf density, biomass, and soybean yield. Field experiments were conducted near Clay Center, Nebraska in 2019 and 2020. The experiment was arranged in a split-plot with velvetleaf height (≤ 12 cm or ≤ 20 cm) as the main plot treatment and herbicides as sub-plot treatment. Fluthiacet provided ≥ 94% velvetleaf control 28 d after treatment (DAT) and ≥ 96% biomass reduction regardless of application rate or velvetleaf height. Velvetleaf control was 31% to 74% at 28 DAT when dicamba or glyphosate was applied alone to velvetleaf ≤ 20 cm tall compared with 47% to 100% control applied to ≤ 12 cm tall plants. Dicamba applied alone to ≤ 20 cm tall velvetleaf provided < 75% control and < 87% biomass reduction 28 DAT compared with ≥ 90% control with dicamba at 560 g ae ha−1 + fluthiacet at 7.2 g ai ha−1 or glyphosate at 1,260 g ae ha−1. Dicmaba at 280 g ae ha−1 + glyphosate at 630 g ae ha−1 applied to ≤ 20 cm tall velvetleaf resulted in 86% control 28 DAT compared with the expected 99% control. The interaction of dicamba + fluthiacet + glyphosate was additive for velvetleaf control and biomass reduction regardless of application rate and velvetleaf height.

The method used in this research was two-factor Randomized Block Design with split plot arrangement and three replications. The main plot was the mulch type which consists of three treatments, namely: control, cogon grass and silver-black plastic mulch, and as sub plot was the dose of gandasil-B which consists of four 4 levels, namely: 0, 1, 2, and 3 g L-1 water. Results showed that the interaction between different types of mulch and gandasil-B fertilizer only had significant effect on the diameter of the stem, the number of productive branch, the number of fruit per plant, and the weight of fruit per plant. The utilization of silver-black plastic mulch and gandasil- B fertilizer at the concentration of 3 g L-1 water showed more number of productive branch (14.00 branches) and number of fruit (151.17 fruits) per plant and the weight of fruit (166.52 g) per plant was significantly higher.Keywords : Mulch, cogon grass, silver-black plastic, Gandasil-B, inland peat soil                                                                                                                                       ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh jenis mulsa dan pupuk gandasil-B terhadap pertumbuhan dan hasil tanaman cabai rawit (Capsicum fruestescens L.) pada tanah gambut pedalaman.

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 wheat are mainly determined by the plant production system, thus we studied the effect of mineral fertilization. The field trials were set up in 1983 at the Látókép Research Institute of the University of Debrecen. We examined effect of different Nfertilizer doses (60 kg ha-1 N/P/K, 120 kg ha-1 N/P/K) on Lupus, Mv Toldi and GK Csillag's protein properties in 2012. During the tests, three quality parameters were determined: wet gluten content (%), wet gluten spread (mm/h) and gluten index (%). In the experiment the effect of different doses of N-fertilizers significantly influenced by the wet gluten content and gluten index of Lupus.

Tujuan penelitian untuk mengkaji dampak tingkat dekomposisi serasah daun dan agen pengendali hayati+NPK terhadap pertumbuhan hasil cabai merah. Percobaan menggunakan split plot, disusun menurut Rancangan Acak Kelompok Lengkap dengan tiga ulangan. Sebagai Main plot adalah Dekomposisi serasah daun dengan rasio C/N 28,52 dan dekomposisi serasah daun dengan rasio C / N 16,57. Sub plot adalah jenis agen pengendali hayati dengan enam perlakuan sebagai berikut: 1) Hanya menggunakan NPK dosis rekomendasi (500 kg.ha-1), 2) Kombinasi Trichoderma + 50 % dosis NPK, 3) Kombinasi Mikoriza + 50 % dosis NPK, 4) Kombinasi PGPR + 50 % dosis NPK, 5) Lem pengendalian hama, 6) Stimulant. Data dianalisis varians diikuti oleh Uji Jarak Berganda Duncan. Hasil penelitian menunjukkan bahwa dekomposisi serasah daun dengan rasio C / N 16,57 secara signifikan memperbaiki tinggi tanaman pada hari ke umur 3 MST, jumlah cabang umur 5 MST dan 7 MST serta jumlah buah dan  bobot buah panen pertama dan kedua dibandingkan dengan cabai yang diberi perlakuan dekomposisi serasah daun dengan rasio C / N 28,52. Tanaman lebih tinggi pada penyemprotan stimulan+50% dosis NPK, tetapi tidak diikuti oleh pertumbuhan cabang, serta jumlah dan bobot buah. Kombinasi agen pengendali hayati  jenis Trichoderma sp, Mikoriza sp. dan PGPR + dosis 50% NPK meningkatkan jumlah cabang serta menghasilkan jumlah dan bobot buah, namun, tidak ada perbedaan yang signifikan antara ketiga jenis agen pengendali hayati. Pertumbuhan tanaman yang diberi pupuk NPK memiliki pertumbuhan tanaman paling rendah dibandingkan dengan perlakuan lainnya.
