Color Shading

Nowadays, shading net is widely use in Thailand, especially for vegetable production. Many colors of shading net can be found in the market. In this experiment, we set up three net houses for lettuce by using three colors of 50% transparent shading net, black, red and green. Ten of 15 days after planting (DAP) lettuces were moved to each color net house and control (direct sun). Total 40 lettuces were used for 10 days experiment. The result showed that the leave length and width of lettuce under red shading net respectively were significantly bigger than those under green shading net and control treatment without significant difference with the black shading net. The lettuce under red shading net had a highest stem diameter, fresh weight and dry weight comparing with others color shading net. The spectra of the solar radiations that transmitted through the red shading net were suitable for the photosynthesis of the lettuce leaves that could promote lettuce growth and yield.

Exploring ways to improve stand establishment and crop productivity under abiotic stresses like drought is important. Two years experiments were conducted at University of Agriculture, Peshawar-Pakistan to examine the efficacy of six pre-sowing seed hardening agents. Seeds of wheat cultivar Uqab-2000 were hardened in six different chemicals of various concentration viz; PEG-8000 (10%), CaCl2 (4%), KNO3, (3%), Mannital (4%), NaCl (5%), Na2SO4 (2%) along with water soaking and dry seeds as control for 24 hours and drying back to original moisture content at room temperature. The soaking and drying of seeds was repeated twice for 12 hours. The results showed that pre-sowing hardening of seed with PEG-8000, CaCl2 and KNO3 gave higher germination, decreased days to 50% germination, increased shoot length, root length, seedling fresh and dry weight in laboratory experiment as compared with other hardening and control treatment. Under field conditions, maximum plant height (93.53cm), spikelet’s spike-1 (17.16), grains spike-1 (50.82), 1000 grain weight (39.97 g), grain yield (3482 kg ha-1) and maximum harvest index (32.5%) were observed in PEG-8000 hardened seed than control treatment (2872 kg ha-1). Seed hardened in PEG-8000, CaCl2 and KNO3 gave 30% increase in grain yield as compared to Mannital, NaCl and Na2SO4 which gave 15% increase in grain yield over control treatment.

ABSTRACT Clubroot, caused by Plasmodiophora brassicae, is a disease that limits the cauliflower cultivation and is difficult to control. This study aimed to evaluate the efficiency of liming combined with the use of Trichoderma harzianum-based biofungicide for the control of clubroot in cauliflower. In a field experiment, the use of the biofungicide in combination with the application of calcined limestone doses (0 Mg ha-1, 1.0 Mg ha-1, 2.0 Mg ha-1 and 4.0 Mg ha-1) was evaluated. Subsequently, in a greenhouse, the biofungicide combined with liming with quicklime (2.54 Mg ha-1) was tested, and cyazofamid and water were tested as controls. The disease severity and attributes related to root and plant development were analyzed. In the field experiment, the healthy root volume and fresh weight, total root dry weight and inflorescence fresh weight and diameter were all significantly increased, while the diseased root volume, in response to the limestone doses, was reduced. The biofungicide reduced the root growth and inflorescence fresh weight. In the greenhouse, liming increased the healthy root volume and fresh weight, as well as total root dry weight, and reduced the disease severity. No significant difference was observed between the biofungicide and the control (water), which were inferior to cyazofamid. The biofungicide was not efficient in controlling the disease and did not favour the growth of cauliflower plants, either alone or combined with liming. Liming reduced the disease severity and increased the cauliflower root growth and yield.

Resistance induction through the use of chemical inducers often results in physiological costs to the plant. In this study, induced resistance in cotton plants was evaluated with regard to physiological costs in a cultivar susceptible to Colletotrichum gossypii var. cephalosporioides (CNPA GO 2002 - 7997). Plants were cultivated in substrates with two levels of nitrogen and received two applications of acibenzolar-S-methyl (ASM), jasmonic acid (JA) and Agro-Mos® (AM) disease resistance inducers. Plant height (H), internodal length (IL), shoot fresh weight (SFW), root fresh weight (RFW), shoot dry weight (SDW) and root dry weight (RDW) were evaluated. The activity of the phenylalanine ammonia lyase (PAL) and peroxidase (POX) was also determined. The plants treated with ASM presented high physiological costs with an accentuated reduction in H, SFW and SDW, whereas those treated with JA exhibited a significant increase in SDW, and did not significantly differ from H and IL. In the potting mix supplemented with nitrogen, all inducers differed from the control treatment regarding to internodal length, whereas only ASM and AM presented a significant difference between one another in the potting mix without the addition of nitrogen. Significant correlations (P=0.05) were found for most of the variables analyzed, with greater correlations observed between SFW and SDW (0.94); IL and H (0.74); SFW and H (0.70); and SDW and H (0.70). ASM induced the least amount of PAL activity, significantly differing from the remaining treatments. Greater POX activity was observed in ASM, which significantly differed from the control. AM and JA, however, presented lower activity than the control with regard to these enzymes, and it was not possible to confirm induction resistance in these two treatments.

An experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during  the period from November 2010 to January 2011 to study the effects of cowdung and potassium on growth and yield  of Kohlrabi. The experiment consisted of three levels of cowdung (0, 20 and 40 t/ha) and four levels of potassium (0,  20, 50, 80 kg /ha). The experiment was laid out in randomized complete block design with three replications. All the  parameters were significantly influenced by application of cowdung and potassium. The highest plant height (44.65  cm), number of leaves per plant (12.11), length of largest leaf (37.54 cm), and breadth of largest leaf (18.66 cm) were  obtained from the highest dose of cowdung and potassium applied (40 t cowdung + 80 kg K/ha) while the lowest  plant height (33.64 cm), number of leaves (9.01), length of largest leaf (27.94 cm), and breadth of largest leaf (11.00  cm) were obtained from control treatment combination. The highest fresh weight of leaves (49.33 g), fresh weight of  knob (328.66 g) and fresh weight of roots (66.55 g) per plant were also recorded under the treatment combination of  40 t cowdung + 80 kg K/ha, while the lowest fresh weight of leaves (22.11 g), fresh weight of knob (136.00 g) and  fresh weight of roots (23.33 g) were obtained from control treatment combination. Similarly, the dry weight of leaves  (19.34%), knob (15.19%) and roots (32.75%) were highest under the same treatment combination of 40 t cowdung +  80 kg K/ha and the lowest dry weight of leaves (11.71%), dry weight of knob (7.38%) and dry weight of roots  (15.29%) were obtained from control treatment combination C0K0. The marketable yields of knob per plot (7.86 kg)  and per hectare (39.58 tons) were also the highest under the treatment combination 40 t cowdung/ha and 80 kg  potassium per hectare.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12035   J.

This study aims to determine the effect of giving T. asperellum and compost on the growth and yield of shallots of the Palu Valley variety. This research was conducted on July to September 2019 in Oloboju Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi Province. This research is a kind of experimental research that is designed by using a Randomized Group Design  with grouping based on watering time. The treatments tested consisted of: P0 = Control (without treatment), P1 = T. asperellum 48g + 12 liters of water, P2 = T. asperellum 48g + 12kg compost and P3 = 12kg compost. To determine the effect of the treatment being tried, a diversity test was conducted. If the diversity test results show a real influence, then proceed with the Honestly Significant Difference test (BNJ) α = 0.05 to find out the differences between treatments. Treatment of various combinations of T. asperellum and compost significantly affected plant height at ages 15 and 25 HST, but had no significant effect on the number of leaves, leaf fresh weight, root fresh weight, leaf dry weight, root dry weight, number of tubers per clump, fresh tuber weight per clump, fresh tuber weight per plot and fresh tuber weight per hectare. The compost treatment gives a better effect on the height of plants aged 15 HST (average 15.09cm) and 25 HST (average 19.86cm).

This study was conducted to evaluate the growth and yield of maize to compost, organomineral fertilizer, and mineral fertilizer at Iyaganku and Moniya farm sites in Ibadan, Oyo State, Nigeria. Treatments consisted of Organomineral fertilizer (A), Compost (B), Fresh compost (C), Mineral fertilizer (D = N.P.K. 15:15:15), and Control (E = no fertilizer). Experimental design was randomized complete block design replicated four times. Compost treatments (45 kgNha-1) were applied at one week before sowing while N.P.K. 15:15:15 fertilizer (300 Kg N ha-1) was applied two weeks after sowing. The growth and yield data collected were analyzed using Analysis of Variance (ANOVA) of GENSTAT Discovery software. Significant means were compared using Duncan Multiple Range Test (DMRT) at p = 0.05. The results of the analysis revealed no significant difference in the number of leaves and stem girth at 8 weeks after sowing (WAS) at Iyaganku. Tallest maize plants were recorded from plots treated with A and B. Also, treatments showed no significant difference in the dry weight (g/cob) of husked and unhusked maize at harvest. At Moniya, plots treated with A produced high number of leaves while lowest number of leaves were recorded from control plots and plots treated with B, C, and D. Similarly, no significant difference was observed in stem girth, plant height, dry weight (g/cob) of husked and unhusked maize at harvest between control plots, and plots treated with C, and D. Larger stem girths, tallest plants, dry weight (g/cob) of husked and unhusked maize at harvest were observed in plots treated with A and B. The results from Moniya farm site suggest that organomineral fertilizer and compost have the potential to enhance the growth and yield of maize in studied location.

A pot experiment was conducted to study the effect of goat manure and sugarcane molasses on the growth and yield of beetroot (Beta vulgaris L.) in sandy regosol. The experiment was laid out in a completely randomized design (CRD) with six treatments. The treatments included inorganic fertilizer (T1), 10 t/ha of goat manure alone (T2) and also 10 t/ha of goat manure and 50% triple superphosphate (TSP) with 1-4 t/ha of sugarcane molasses (T3-T6). The results showed that plant growth parameters (leaf length, leaf petiole length, leaf width, leaf number, fresh weight and dry weight of leaves) were significantly varied among the treatments. There was a significant difference in the diameter of beetroot among the treatments. Significant differences (P<0.05) were observed in fresh weight of beetroot and total plant among the treatments. Fresh weight of root yield and total yield of beetroot per plant were increased in 10 t/ha goat manure, 2 t/ha sugarcane molasses and 50% TSP (T4) and 10 t/ha goat manure, 3 t/ha sugarcane molasses and 50% TSP (T5) when compared to the control treatment (T1). The total yield of beetroot per m2 was 1,792.62 g in T4 and 1,402.68 g in T1. The root yield of beetroot was increased in T4 in comparison to T5. It can be concluded that 10 t/ha of goat manure with 2 t/ha of sugarcane molasses and 50% TSP could be applied for obtaining a high yield of beetroot in sandy regosol.

The experiment was conducted at the Agricultural Research Field of International University of Business Agriculture and Technology, Dhaka during the period from August to October 2020 to investigate the response of different doses of nitrogen fertilizer on the growth and yield of Kangkong (Ipomoea reptans poir). The experiment consisted of four nitrogen fertilizer levels viz. T0: no fertilizer, T1: 60 kg nitrogen fertilizer, T2: 80 kg nitrogen fertilizer, and T3: 100 kg nitrogen fertilizer per hectare. The result revealed that plant height, number of leaves per plant, number of branches per plant, fresh weight per plant, dry weight per plant, root length per plant, fresh weight of root per plant, dry weight of root per plant, yield per plot and yield per hectare grown under different doses of nitrogen fertilizer viz. control (T0), 60 kg N per hectare (T1), 80 kg N per hectare (T2), showed significant reduction than those grown in 100 kg N per hectare (T3). The experiment was conducted following Randomized Complete Block Design (RCBD) with four replications. The application of different doses of nitrogen significantly influences the growth and yield of Kangkong. The maximum plant height, number of leaves, number of branches, fresh weight per plant, root length was obtained from T3 treatment while the minimum was found from the control treatment (T0) at 60 days after sowing. The highest yield (17.87 t/ha) was performed from the treatment T3 and the lowest yield (11.83t/ha) was obtained from the control treatment where no nitrogen was used.
