Instead, the co-inoculation of Rhizobium, Azospirillum and Trichoderma may play the same role; however, its effects are unknown in common bean. This work aimed to evaluate the effects of co-inoculating three microorganisms on the development, nodulation

ABSTRACT Silicon, the second most abundant element on the Earth crust, is often considered beneficial for plant nutrition. However, plant available fraction of silicon (Si) is hard to find and extract from many types soils. Soil reaction (pH), temperature and plant uptake are some of the major determinants of Si availability affecting its extraction from soil. In this experiment, neutral, acidic and

ABSTRACT Silicon (Si) is classified as a beneficial element in higher plants. Although there is an abundance of literature on Si extraction and analysis in graminaceous crops such as rice and sugarcane, there is limited information on the validation of these methods for most dicotyledonous horticultural crops. These methods include gravimetric extraction, which requires a larger sample size the smaller

ABSTRACT Soil biology influences soil nutrient cycling and crop nutrition, and yet, the use of synthetic fertilizers supersedes the need for crop producers to improve soil biological health. A big reason is that soil biology is complex and is difficult for the farmers to assess the biological health of their own soils. Two separate studies were designed to test a novel protocol to study soil biology

However, there was limited information about influence of long-term fertilizer management on soil microbial community in the double-cropping

ABSTRACT For enhanced soil fertility, the application of animal manure has been recognized as an alternative mean to synthetic fertilizers. A major issue in current manure application practices is the rapid, reliable estimation of nutrients, such as nitrogen (N) and phosphorus (P). Estimation of N and P in manure involves the use of harsh chemicals and conditions, and considerable analytical time.

ABSTRACT Water shortage is the main limitation for agricultural production in many parts of the world. Drought or unavailability of water may seriously limit plant growth as well as yield. A pot experiment was carried out to evaluate the effects of various irrigation strategies, i.e., Full (FI), deficit (DI) and partial root-zone drying (PRD) on physiological, biochemical and yield-related attributes

ABSTRACT To evaluate the forage yield and quality of Berseem and Persian clover cultivars, a two-year experiment was conducted during two growing seasons (2017–2018 and 2018–2019).

The sub-factor consisted of ten cultivars of clover, five of which were Persian clover (Pars

ABSTRACT Poor soil aeration is a limiting factor that influences rice (Oryza sativa L.) growth. Oxygenated compound fertilizer (OCF) is a vital strategy to address this challenge by improving soil aeration. Three kinds of newly developed fertilizers amended with different amounts of calcium peroxide (OCF1, OCF2, and OCF3) were prepared by mixing nutrients and other additive materials. Using waterlogging

ABSTRACT Plant spacing and density are important metrics in crop production because they impact the plant’s ability to utilize resources and attain full yield potential. Planting sorghum (Sorghum bicolor (L.) Moench) in a more narrow spacing brings about phytochrome-mediated responses, where plants develop narrow leaves, long stems, fewer roots, and this is linked to competition that plants develop

ABSTRACT This field investigation was conducted to assess the implication of the direct and residual effect of the applied differential level of boron on the dynamics of the soil chemical properties, nutrient status in soil and yield of crops under cauliflower–cowpea-okra cropping sequence in an Inceptisol of North East India. The imposed treatments comprise five levels of boron viz., 0, 0.5, 1.0,

ABSTRACT One of the main problems with soil chemistry of phosphorus (P) fertilizers is its limited availability by plants. Residual P remains on the soil surface and may cause environmental problems. The use of materials such as peat moss is not cost-effective in some countries due to its scarcity and high price. This study was performed to reduce the use of chemical fertilizers and limited expensive

ABSTRACT Crop responses to nitrogen (N) fertilization reportedly depend on the storage of soluble N in the soil profile from the previous N-fertilization. We examined the profile storage of dissolved inorganic, DIN (NH4-N + NO3-N), and dissolved organic N, DON, in a savanna soil fertilized for over 50 years with farmyard manure, FYM, NPK-fertilizer, and their combination, FYM+NPK, along with a control

The prairie agricultural surface soils (0–10 cm) used in the study were suspected to be micronutrient deficient according to soil

ABSTRACT An attempt to mitigate rapid soil fertility and productivity decline has led to the application of organic and inorganic fertilizers. However, the availability of inorganic fertilizers for crop production is a challenge to many farmers in developing countries. Thus, the use of organic fertilizers is becoming more popular among farmers in recent decades. In this study, a two-year field experiment

ABSTRACT Soil acidity is one of the most limiting factors in crop yield. We evaluated the effect of soil acidity correction with magnesium limestone and calcium (Ca) and magnesium (Mg) silicate associated gypsum application, on the growth of a forage grass. The experiment was conducted in a greenhouse with a soil sample from B horizon of a Rhodic Hapludox. The experimental, design was completely randomized

ABSTRACT Lime and gypsum application is one strategy for correcting soil acidity and improving soil fertility. However, soil compaction in no-till systems can influence these dynamics. This study aimed to assess the effect of lime and gypsum application under different soil compaction levels on soybean yield and soil chemical attributes. The application of lime and gypsum under artificial compaction

HA effects on plants and soil are regulated by concentration and mode of application. The aim of this study was to evaluate the nutrient availability in soil and the eucalyptus nutrition and growth as related to concentrations of HA added to soil or used to soak eucalyptus seedlings

ABSTRACT Sandy soil is typically poor in organic matter. When areas with sandy soil are used for pasture prior to soybean cultivation, the availability of nitrogen (N) for plants is limited even further. Our objective was to evaluate if inoculation combined with N fertilization increases N content in the soil and N supply to soybean plants in post-pasture and post-soybean areas. Four experiments were

ABSTRACT Different planting ages of forests will have a certain impact on the physical and chemical properties of the soil. This study investigated whether different growth years of hazelnut have an influence on soil organic carbon (SOC) content and humic acid (HA) structure. To do this, four treatments were implemented: no hazelnut planting (CK), hazelnut planting 2 years (A2), hazelnut planting 4 years
