Impact of integrated organomineral fertilizer application on growth, yield, quality, and health-related compounds of sweet corn

In this study, the effectiveness of two organomineral formulations (OMF I and OMF II) on the growth, yield, kernel quality and health-related compounds of sweet corn were evaluated. OMFs were compared with chemically fertilized and unfertilized control to evaluate their effects as a basic fertilizer source. Field experiments were conducted using a randomised complete block design, with three replications over 2 years. Two cultivars (cv. ‘Sentinel’ and cv. ‘Khan’) were used as plant material. The results indicated that (1) compared to control, the application of organomineral and chemical fertilizers resulted in improvements in most growth, yield and quality traits of sweet corn in both cultivars; (2) use of organomineral fertilizers led to similar or significantly higher than chemical fertilizer in plant height, leaf number per plant, ear size, ear weight, ear yield (husked and de-husked) and total soluble solids. However, these effects showed responses that varied with type of organomineral fertilizer or cultivar; (3) use of OMF I treatment with cv. ‘Khan’ significantly improved ear size, ear weight, ear yield (husked and de-husked), colour traits, total phenolic content and antioxidant activity compared to other treatments.

Influence of Biostimulants and Microbiological Preparations on the Yield and the Occurrence of Diseases and the European Corn Borer (Ostrinia nubilalis Hbn, Lepidoptera, Crambidae) on Sweet Corn (Zea mays L. Var. saccharata)

The aim of this work was to determine the influence of chosen biostimulants and microbiological preparations on the yield of sweet corn and the occurrence of Ostrinia nubilalis Hbn, and diseases. In both years of the study, the preparations used in this experiment did not have a statistically significant effect on marketable yield; however, in 2017, the highest weight was observed in the cobs of plants treated with Rizocore and Polyversum WP while the lowest in the cobs treated with RhizoVital 42. The biostimulant Asahi SL and the biological fungicide Serenade ASO proved to be the most effective in protecting sweet corn against cob and shoot infections by fungi of the genus Fusarium. All the preparations reduced the development of the common smut in corn, especially on the cobs. There were no statistically significant differences in cob infection by the O. nubilalis in the combinations treated with different preparations, although the lowest number of cobs damaged by pest in both years were observed on plots treated with Serenade ASO and RhizoVital 42, while the highest on plots treated with Goëmar BM.

Comparison of different fertilization rates on yield, evapotranspiration, and water use efficiency of sweet corn under drought-salinity stresses

The present study investigated the effects of three fertilization (N-P2O5-K2O) rates (F1: 240-100-120 kg ha-1, F2: 192-80-96 kg ha-1, F3: 154-64-77 kg ha-1) coupled with four irrigation practices (Control: C, irrigated at the 100% field capacity, Drought: D, irrigated 60% of C, Saline: S, irrigated at the 100% field capacity, Drought and saline: D+S, irrigated 60% of S) on sweet corn yield, evapotranspiration (ET), water use efficiency (WUE), and shoot fresh-dry weights. The obtained results depicted that the grain yield at D, S, and D+S treatments decreased by 24.2%, 46.6%, and 62.0%, respectively, relative to the C treatment. Moreover, grain yield at the F3 condition was reduced by 45.3% compared to the F1 condition. Additionally, the highest ET (330.7 mm) and yield (74.0 g) was achieved with F1×C treatment. The F2 and F3 treatments reduced WUE by 17.9% and 31.5%, respectively, compared to the F1 treatment. The highest reduction in yield, ET, WUE, and shoot fresh-dry weights was found at D+S irrigation treatment under all fertilization conditions. The tallest plants were observed in the F1×C treatment, being 24.0%, 33.5%, and 43.2% taller than plants in the F1×(D+S), F2×(D+S), and F3×(D+S) treatments, respectively. Under F3 conditions, exposing sweet corn plants to single or combined salinity and drought stress remarkably degraded the growth ability of the plants, and therefore, it is not economical and sustainable cultivation for agriculture. Finally, cultivation of sweet corn plants under individual or combined drought-salinity stress is not recommended due to the high reduction in grain yield.

Response of N uptake, N-total and yield of sweet corn (Zea mays saccharata Sturt) due to fertilization with granulated solid organic fertilizer and NPK in Inceptisol soil

Sweet corn productivity is greatly influenced by proper cultivation techniques, of which fertilization is one of the main factors. Effective fertilization not only supports plant growth but also affects nutrient uptake and yield. This study aimed to evaluate the effect of granulated solid organic fertilizer and NPK fertilizer on nitrogen (N) uptake, soil N-total content, and sweet corn yield in Inceptisol soil. The research was conducted from February to June 2024 at the Experimental Field, Faculty of Agriculture, Padjadjaran University with treatments including control, NPK fertilizer, and various combinations of granular organic fertilizer and NPK. The results showed that the combination of granule organic fertilizer and NPK significantly increased nitrogen uptake and N-total content in the soil compared to the single NPK application. In addition, sweet corn yield, as measured by cob weight per plant, per plot, and per hectare, also increased significantly with the fertilizer combination treatment. This study supports the use of fertilization strategies that integrate organic and inorganic fertilizers as an effective way to increase sweet corn productivity on soils with limited fertility, such as Inceptisol. The application of a combination of 1 NPK + 1 granulated organic fertilizer was the best combination in increasing N uptake, N-total and sweet corn yield.

Performance of agricultural factors on yield of sweet corn (Zea mays L. Saccharata ) - A review

Sweet corn producers and industries require more reliable cultivars which could be accomplished by hybrid breeding. However, progressive phenological growth may be affected by different factors. In this paper, we analyze the key factors that determine the growth and yield of sweet corn. Environmental factors such as temperature and photoperiod were strong determinants of dates of flowering and harvest which are often crucial to yield in diverse climates and agricultural systems, besides the country's pedological conditions, especially soil fertility, affected phenological development. The effectiveness of fertilization in improving sweet corn growth performance was significantly influenced by the soil characteristics, the water supply, the genotype, and the agrotechnological factors. Therefore, genetic improvement of hybrids should be incorporated into the climate and soil elements to stabilize sweet corn yields in various agroecosystems. Decisions made in the sowing period are very significant, as up to 30% of the obtained yield may depend on making the proper choice. Deviation from the optimum date (either early or late sowing) may decrease yield. When deciding about the sowing date of maize, one needs to consider climate, soil quality, geographical location, temperature, weed infestation, sowing seed quality, and the ripening time of the hybrid to be produced.

The influence of foliar macronutrient on growth and yield of sweet corn grown in Rengam and Rasau soil series under greenhouse conditions

The purpose of this study was to determine the effects of different rates of macronutrients as a foliar applications on growth and yield performance of sweet corn cultivated in Rengam and Rasau soil series of Malaysia under greenhouse condition. The study comprised five treatments of macronutrient fertilization as a foliar application (0, 25, 50, 75 and 100 % NPK). The plant height, stem width, leaf number, leaf area and cob height of sweet corn grown in Rengam soil series were significantly influenced by foliar macronutrient application. Notably, a rise in cob weight of sweet corns cultivated in Rasau soil series was observed at the 75 % rate, reaching 75 g, compared to 68 g for sweet corn grown in Rengam soil series. The foliar application of 100 % NPK resulted in the highest total leaf area at 252.92 cm2 compared to all other treatments. Regarding the cob fresh weight and dry matter content of sweet corn cultivated in the Rasau soil series, significant improvement noted with the 75 % NPK treatment, however plants grown in the Rengam soil series and treated with 75 % NPK as a foliar application did not exhibit significant effects. The concentrations of Fe and Mn in the corn stem from both soil series significantly increased with macronutrients foliar application. In the corn leaves grown in Rengam soil series, the concentration of nutrients was significantly influenced by the rate of NPK used as a foliar application in this study. Notably, the increased of Ca content in the treated leaves was significantly higher compared to control plants. Additionally, the contents of P, K, Cu and Zn in the corn flower of the plants in the Rengam soil series were significantly elevated in treated plants compared to untreated ones. Conclusively, based on this greenhouse study, it can be inferred that two foliar sprays of macronutrient solution at rates of 75 % and 100 % NPK greatly enhanced the growth, yield and nutrient contents of sweet corn cultivated in the Rengam and Rasau soil series.

Effect of Various Weed Management Options on Weed Dry Matter, Yield Attributes and Yield of Sweet Corn (Zea mays L. saccharata) under Organic Production System

A field experiment was conducted at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during kharif 2019 entitled “Effect of various weed management options on weed dry matter, yield attributes and yield of sweet corn (Zea mays L. saccharata) under organic production system”. The soil of the experimental site was clayey in texture, neutral in reaction and low in nitrogen, medium in phosphorus and high in potassium. The experiment was laid out in Randomized Block Design with three replications. The weed flora of the experimental site was dominated by Echinocloa colona, Alternanthera sessilis, Parthenium hysterophorus, Cyperus iria. Results revealed that the highest green cob yield of sweet corn was recorded in stale seed bed + reduced spacing (upto 25%) + mulching with paddy straw + 20 DAS hand weeding (7.63t ha-1 ) which was 83.48% higher than the weedy check. The green cob yield in stale seed bed + reduced spacing (upto 25%) + mulching with paddy straw + 20 DAS hand weeding was found to be at par with mulching with waste polythene bags (ITK-practices) (7.45t ha- ), hand weeding twice carried out at 20 and 40 DAS (7.33 t ha-1) and soil solarization with 25µ polythene mulch during summer + one hand weeding at 20 DAS(6.94t ha-1). Although grain yield in other weed management practices was significantly lower than stale seed bed + reduced spacing (upto 25%) + mulching with paddy straw + 20 DAS hand weeding treatments but higher than weedy check. Similarly, As regards total weed dry weight at harvest, the total lowest weed dry weight was observed in stale seed bed + reduced spacing (upto 25%) + mulching with paddy straw + hand weeding at 20 DAS(3.45gm-2) followed by mulching with waste polythene bags (ITK- practices)(4.71 gm-2), hand weeding at 20 and 40 DAS (4.96gm-2)and soil solarization with 25µ polythene mulch during summer + one hand weeding at 20 DAS(5.08 gm-2). However, higher WCE was noticed in these treatment over weedy check. The weedy check was significantly inferior in all the yield attributes and green cob yield of sweet corn.
