Streszczenie:

Soil Test Crop Response correlation studies were carried out in maize under Integrated Plant Nutrition System (STCR-IPNS) on Typic Rhodustalf of Tamil Nadu, adopting “Inductive cum Targeted yield model”. The basic parameters for the “Targeted yield model” viz. nutrient requirement (NR), contribution of nutrients from soil (Cs), fertilizer (Cf) and farmyard manure (Cfym) were computed from field experimental data. Using these parameters, the fertiliser prescription equations were developed under IPNS and ready reckoner of fertiliser doses were formulated for desired yield target of maize for a

In a study using data from 57 wheat field experiments on the central-western slopes of New South Wales, eight soil phosphate tests (Bray,, Bray,, alkaline fluoride, Mehlich, Truog, lactate, Olsen and Colwell) were evaluated and calibrated in terms of responsiveness (�) and response curvature (C) parameters derived from the Mitscherlich equation. The results showed that, regardless of how well correlated a soil test is with yield responsiveness, it cannot give a satisfactory estimate of fertilizer requirement unless yield response curvature is also taken into account.

The Soil Test Crop Response (STCR) approach, incorporating the Integrated Plant Nutrient System (IPNS) with a focus on targeted yields, aims to balance the need for "fertilizing the crop" and "fertilizing the soil." This balance is essential for meeting the crop’s fertilizer requirements, improving yield, enhancing fertilizer efficiency, and maintaining soil health, while also ensuring profitability for farmers.

An experiment was conducted twice concurrently at Vom in Plateau State Nigeria in 2011 to evaluate the effects of three animal based organic fertilizers and three rates of application on the growth, seed and herbage yields of Rhodes grass (Chloris gayana var. Callide). This study involved three types (poultry, rabbit and sheep dung) of animal fertilizer and three rates (0, 25 and 50 t ha-1) of application in a 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Animal fertilizers significantly (p < 0.05) increased growth, seed, fresh herbage

Fertilizer is a crucial and strategic requirement for enhancing production, productivity, quality, and competitiveness of agricultural products across various sectors, including food crops, horticulture, smallholder plantations, livestock, and fisheries. Given its importance, it is deemed necessary to subsidize fertilizers. However, issues arise with fertilizer subsidies, such as the yearly increase in the budget allocated for these subsidies, which poses a significant burden on the government. Additionally, the low cost of urea (N) makes it susceptible to misuse in terms of excessive and unba

Growth and yield of ‘Misty’ and ‘Star’ southern highbush blueberry (Vaccinium corymbosum hybrid) plants that were grown in pine bark culture were evaluated under several rates of granular or liquid fertilizers. Granular fertilizer resulted in larger canopy volumes and slightly greater annual fruit yield than liquid fertilizer. In 2003 and 2004, canopy growth increased linearly as fertilizer rate increased up to the highest rate tested [81 g nitrogen (N), 11.8 g phosphorus (P), and 44.6 g potassium (K) per plant per year].

The solid waste from agar processing industries in Indonesia is enormous. The waste contains numbers of macro and micro nutrient including growth hormone that can be a good source for plant fertilizer. Utilization of solid waste obtained from agar processing into fertilizer has been carried out by mixing with Sargassum powder, fish silage and Eucheuma cottonii pasta. Various concentrations of the solid waste (13, 19, 22 and 25%) and the Sargassum powder (0, 3, 6, 9, and 12%) were used in this study to obtain optimum nutrients in the formulated fertilizers i.e. growth hormone, total nitrogen an

Fertilizers are the chemicals that are added to soil so that necessary nutrients can be provided to the plants for increased crop production. Primarily Nitrogen (50-70%) is added to the soil as a conventional source of fertilizer. It is identified as the most significant element for the growth of the plants. In India, urea alone supplies about 82% of Nitrogen.As urea itself is highly water soluble, when it is mixed to the soil, immediately the leaching advances and as a result the Nitrogen utilization efficiency (NUE) by plants gets reduced. Therefore, it is essential to improve the formulatio
