“…In the present study, the poor performance of baby corn under the FB was mainly due to water stagnation during the period of active crop growth and development stages which might have retarded the root growth, leaf expansion; dry matter accumulation and photosynthesis rate owing to inadequate oxygen supply in the root zone 56,57 . Furthermore, the crop under the FB system was prone to lodging during heavy rainfall coupled with the intense wind.…”

“…A 30–50% higher cereal yield with BBF planting system over the FB in high rainfall areas has been reported 61 previously also. In the present study, beds of 60 cm width and ~ 15 cm height were made under BBF which allowed effective drainage of water from the plant’s root zone and reduced the probability of water-logging and soil compaction by improving the infiltration and rhizospheric aeration 62 and nutrient availability to plants 57 , 63 , which ultimately led to better plant growth and yield. Additionally, BBF sowing might have improved the solar radiation interception by crop canopy, thereby reducing the biotic stresses 64 and increased baby corn cob yield.…”

“…However, irrespective of the treatment one hand weeding was given at 20 DAS. The crop was detasseled (removal of male inflorescences) before initiation of pollen shedding (55)(56)(57)(58)(59)(60) to prevent fertilization and divert nutrient flow towards the baby cobs. At the time of harvesting, five plants were randomly selected from each plot for the recording of growth parameters.…”

Appropriate land configuration and assured nutrient supply are prerequisites for quality organic baby corn (Zea mays L.) production in high rainfall areas of the delicate Eastern Himalayan Region of India. A long term (5-year) study was conducted during 2012–2016 on a sandy loam soil in the mid attitude of Sikkim, Eastern Himalayan Region of India to evaluate the productivity, produce quality, the profitability of baby corn, and soil properties under different land configurations comprising flatbed, ridge and furrow, and broad bed and furrow, and organic nutrient management practices comprising un-amended control, farmyard manure 12 t ha−1, vermicompost 4 t ha−1 and farmyard manure 6 t ha−1 + vermicompost 2 t ha−1. The baby corn sown on broad bed and furrow had the tallest plant (149.25 cm), maximum dry matter (64.33 g plant−1), highest leaf area index (3.5), maximum cob length (8.10 cm), cob girth (6.13 cm) and cob weight (8.14 g) leading to significantly higher fresh baby corn yield (1.89 t ha−1), and net returns (US$ 906.1 ha−1) than those of other treatments. Mineral composition (phosphorus, potassium, iron, and zinc), protein, and ascorbic acid content were also the highest in baby corn grown under the broad bed and furrow system. The soil of broad bed and furrow had a higher pH, organic carbon content, organic carbon pools, microbial biomass carbon, and enzymatic activities (dehydrogenase, fluorescein diacetate, and acid phosphatase) compared to soils of other land configurations. A combined application of farmyard manure (6 t ha−1) + vermicompost (2 t ha−1) improved the crop growth and produced 117.8% higher fresh baby corn and 99.7% higher fodder yield over control (0.9 t fresh corn and 13.02 t fodder yield ha−1), respectively. This treatment also registered significantly higher gross return (US$ 1746.9 ha−1), net return (US$ 935.8 ha−1), and benefit–cost ratio (2.15) than other nutrient management practices. Fresh cob quality in terms of protein (22.91%) and ascorbic acid content (101.6 mg 100 g−1) was observed to be significantly superior under combined application of farmyard manure (6 t ha−1) + vermicompost (2 t ha−1) than those of other nutrient management systems. However, fresh baby corn cobs produced with vermicompost 4 t ha−1 had the highest concentration of phosphorus, potassium, iron, and zinc. Application of farmyard manure 12 t ha−1 registered the maximum increment in soil organic carbon content (1.52%), its pool (40.6 t ha−1) and carbon sequestration rate (0.74 t ha−1 year−1) followed by integrated application of farmyard manure (6 t ha−1) and vermicompost (2 t ha−1). The maximum soil microbial biomass carbon and enzymatic activities [dehydrogenase (22.1 µg TPF g−1 soil h−1) and fluorescein diacetate (67.1 µg FDA g−1 soil h−1)] were noted with the combined use of farmyard manure (6 t ha−1) + vermicompost (2 t ha−1). Thus, the study suggests that the broad bed and furrow land configuration along with the combined application of farmyard manure + vermicompost could be an economically feasible practice for quality organic baby corn production and soil health improvement in the Eastern Himalaya and other similar eco-regions elsewhere.

“…Exogenous application of various phosphorus (P) sources such as dairy cow manure (DCM) and meat and bone meal (MBM) is effective for producing optimum yields in P-deficient conditions during a wet growing season (Ylivainio et al, 2008, 2018). Application of farmyard manure also significantly increased grain Fe, Zn, Cu concentration of paddy under flooded conditions (Masunaga and Marques Fong, 2018). Similarly, foliar application of boron has been reported to increase overall plant growth and alleviate deleterious effect of waterlogging of maize (Sayed, 1998).…”

“…Appropriate soil and crop management practices improve soil quality and crop productivity, through improved ecological and economical flexibility by reducing the need for additional agricultural land (Setter and Belford, 1990; Tilman et al, 2002; Shaxson and Barber, 2003). Improved soil management can increase infiltration, reduce surface runoff, and additionally improve availability of water and nutrients to plants (Amare et al, 2013; Negusse et al, 2013; Schmidt and Zemadim, 2015; Masunaga and Marques Fong, 2018). Crop management can contribute to higher yields (Soomro et al, 2009; Amare et al, 2013).…”

Soil and Crop Management Practices to Minimize the Impact of Waterlogging on Crop Productivity

et al. 2019

Waterlogging remains a significant constraint to cereal production across the globe in areas with high rainfall and/or poor drainage. Improving tolerance of plants to waterlogging is the most economical way of tackling the problem. However, under severe waterlogging combined agronomic, engineering and genetic solutions will be more effective. A wide range of agronomic and engineering solutions are currently being used by grain growers to reduce losses from waterlogging. In this scoping study, we reviewed the effects of waterlogging on plant growth, and advantages and disadvantages of various agronomic and engineering solutions which are used to mitigate waterlogging damage. Further research should be focused on: cost/benefit analyses of different drainage strategies; understanding the mechanisms of nutrient loss during waterlogging and quantifying the benefits of nutrient application; increasing soil profile de-watering through soil improvement and agronomic strategies; revealing specificity of the interaction between different management practices and environment as well as among management practices; and more importantly, combined genetic, agronomic and engineering strategies for varying environments.
