A multilocational field trial was conducted to investigate the effect of some plant extracts (Bolanite aegyptica, Eucalyptus camaldulensis and Citrus aurantium) and a synthetic antibiotic (Streptomycin) on the incidence and severity of angular leaf spot on five cotton geno-types namely SAMCOT-8, SAMCOT-9, SAMCOT-10, SAMCOT-11 and SAMCOT-12 in Yola and Jalingo, both located in the northern guinea savannah zone of Nigeria. The experiment was carried out on a split-plot design having three replications with cotton genotypes on the main plots and plant extracts on the sub-plots. Data collected on the incidence and severity of the disease were analysed using the Generalized Linear Model procedure and means separation at 5% level of probability by Duncan Multiple Range Test. Findings of the study revealed that Streptomycin and Bolanite aegyptiaca were able to reduce the disease incidence by 18.12% from 58.69% in Yola at 13 WAS. In Jalingo however, B. aegyptiaca was found to have re-duced the disease severity from 52.12% to 19.69% at 13 WAS. SAMCOT-8 consistently recorded lower incidence and severity means in Yola and Jalingo of 47.96%; 59.12% and 40.82%; 39.70% while SAMCOT-12 recorded higher means of 53.29%; 59.82% and 48.03%; 46.70% respectively.

Long bean production in Indonesia continues to decline every year, this is due to land conversion and the lack of application of agricultural technology. One of the efforts to increase long bean production is by multiplying quality seeds using organic materials as nutrients needed by plants. This study aims to determine the response of the growth and production of long bean seeds to the interaction of strains, varieties with a concentration of liquid organic fertilizer. The research was conducted at the Vegetable Crops Research Institute, Lembang, West Bandung Regency from July 2020 to January 2021. The research method used was an experimental method with a Randomized Block Design (RBD) with a split-plot design consisting of 2 factors: the first factor (main plot) (A) was the variety and strain with 2 levels, a1 (Tavi canton variety) and a2 (pras-1 strain).The second factor (subplot) (B) is concentration of biopras-1 with 5 levels, b1 (0 cc/l-1 water), b2 (1 cc/l-1 water), b3 (2 cc/l-1 water), b4 (3 cc/l-1 water) and b5 (4 cc/l-1 water). The effect of the treatment was analyzed by means of variance and if the f test at 5% level was significantly different, then to find out the best treatment was continued with the DMRT (Duncan Multiple Range Test) at the 5% level. The results showed that there was an interaction between varieties, lines with various concentrations of biopras-1 liquid organic fertilizer on dry seed weight per plant, dry seed weight per plot, and 1000 seeds weight. Treatment of pras-1 lines with the concentration of liquid organic fertilizer biopras-1 4 cc / l of water was able to give the best results on dry seed weight per plant (35.31 gr), dry seed weight per plot (1.298.20 gr or 2.16 Ton/ha-1) and the weight of 1000 seeds (153.10 gr).

Aloe vera (Aloe barbadensis) is an important plant to cosmetics, pharmaceuticals, and food industry worldwide. In Colombia its cultivation has grown even when technical crop management is unknown. This study evaluated the growth of three aloe basal shoots weights ranges in two companion planting systems and monoculture (control). A completely randomized split plot design was used. Main plots were: aloe monoculture (AMN), common bean companion planting (CBCP), and giant taro companion planting (GTCP). Treatments were weight ranges from 50 to 150 g (LWe), 151 to 250 g (MW), and 251 to 350 g (HW). Data were analyzed using ANOVA, Duncan multiple range test (P≤0.05), and linear regressions. Variables evaluated were total height (TH), number of leaves (NOL), length (LL), width (LW), and leaf thickness (LT). In CBCP, GTCP, and MW variable LL predicted GH. Models fitted to HW and AMN were not representative (R 2 <0.64). CBCP obtained the highest values in NOL (17.8), TH (56.2 cm), LL (40.2 cm), and LW (5.8 cm). LWe and MW basal shoots reached non-significant differences one year after planting in any variable (P>0.05). Companion planting promotes predictability of aloe growth and CBCP associated with HW are a promising alternative to aloe cultivation.

Five chemicals, incuding Flare, Plant Protector, Mancozeb, Agrimycine, and Copper oxychloride, and five plant extracts including N. tabacum, A. indica, M. oleifera, D. alba and C. longa were evaluated against bacterial blight of cotton caused by Xanthomonas citri pv. malvacearum (a bacterium). The impact of chemicals and plant extracts on bacterial development was tested in laboratory while on disease reduction was tested in green house and field experiments. Laboratory experiments showed that maximum inhibition zone of bacterial growth was expressed by Flare (1.693cm) at all concentrations followed by Plant Protector (1.473 cm), Mancozeb (1.290 cm), Agrimycine (1.150 cm) and copper oxy-chloride (0.953) cm respectively while in case of plant extracts maximum inhibition was expressed by N. tabacum (0.650 cm) followed by A. indica (0.486), M. oleifera (0.350), D. alba (0.256 cm) and C. longa (0.168 cm). Green house experiment revealed that the best result was produced by the combination of Flare and N. tabacum by indicating lowest disease incidence (32.27%) at all the tested concentration. Same results were obtained in field experiment, where the lowest disease incidence (40.41%) was recorded when the ,Flare and N. tabacum were applied in combination although it was higher then green house. This study concludes that N. tabacum and Flare are better option against bacterial disease development and even their combination is more significant lowering the bacterial blight disease incidence on cotton. Selection of suitable formulation and method of application could be the future aspects of plant product especially N. tabacum related research.

Corn and soybean are food crops which are ranked on the second and third position as the main crops with the highest yield in Indonesia. Based on data of 2012, corn and soybean harvested areas amounted 3,956 ha and 597.65 ha with the productivity of 48.99 tons/ha and 843.15 tons/ha, these areas increased up to 4,388 ha (corn) and 589.42 ha (soybeans) which lead an increase in corn and soybean production by 52.85 tons/ha and 887.54 tons/ha. However, increasing crop productivity, especially for corn and soybeans, cannot continuously use land expansion because the land area of Indonesia that is suitable for agriculture is only 94.07 million ha from 188.20 million of total land area. Thus, the solution to overcome this issue is by arranging the plant spacing and providing proper nutrients. Plant spacing in intercropping systems can minimize competition between plants to provide a well-grown of both plants. This research aimed to determine the increase in productivity of corn and soybean plants using intercropping systems through a combination of plant spacing and a combination of NPK fertilizer dosages. This study used a factorial experimental method that planted crops on the land with 2 factors with split-plot design of 4 × 3 factorial and 3 replications. The first factor is the combination of plant spacing with 4 levels, they were plant spacing of corn; 50 cm × 40 cm (J1), 75 cm × 40 cm (J2), 100 cm × 40 cm (J3), 125 cm × 40 cm (J4) and plant spacing of soybean; 40 cm × 20 cm. The second factor is 3 levels of NPK fertilizer dosages combination, they were 0% NPK fertilizer dose of the recommendation (0 g/m2) (D1), 50% NPK fertilizer dose of the recommendation (198.5 g/m2) (D2), 100% of NPK fertilizer dose of the recommendation (397 g/m2) (D3), with 3 replications. DMRT test (Duncan, Multiple Range Test) was performed with a confidence level of 95% when the results between treatments were significantly different.

Penyakit virus kuning dan bercak daun Cercospora merupakan dua penyakit penting yang menjadi kendala dalam budidaya cabai merah besar. Penelitian ini bertujuan untuk menguji konsorsium bakteri antagonis Pseudomonas aeruginosa dan Bacillus cereus dalam mengendalikan penyakit virus kuning dan bercak daun Cercospora pada cabai merah besar serta pengaruhnya terhadap pertumbuhan tanaman cabai merah besar sendiri. Penelitian dilaksanakan pada bulan Oktober 2020 - Desember 2020 di lahan tumpangsari bawang merah dan cabai, Desa Ubalan, Kecamatan Dampit, Kabupaten Malang. Persiapan penelitian meliputi survei lokasi, persiapan alat dan bahan, pengacakan perlakuan, dan penentuan tanaman sampel. Pelaksanaan penelitian meliputi pengaplikasian larutan isolat bakteri antagonis di lapang, pengamatan mingguan, dan pengolahan data. Penelitian disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 9 perlakuan dan 3 ulangan. Data dianalisis menggunakan sidik ragam ANOVA dan uji lanjut DMRT (Duncan Multiple Range Test) pada taraf 5% menggunakan software DSAASTAT. Konsorsium P7 (Pseudomonas aeruginosa + Bacillus cereus 13) lebih efektif dalam menekan penyakit virus kuning, sedangkan perlakuan konsorsium P8 (Bacillus cereus 12 + Bacillus cereus 13) lebih efektif dalam menekan penyakit bercak daun Cercospora. Perlakuan konsorsium tidak memberikan pengaruh terhadap tinggi dan jumlah daun. Namun, konsorsium P7 mampu meningkatkan bobot tanaman cabai meskipun secara statistik tidak berbeda dengan perlakuan lainnya.
