Integrated Fertilizer Prescription Equations for Recommendations of Fertilizers in Jute–Rice–Garden Pea Sequence on Alluvial Soil of Eastern India

Abstract

Field experiment was conducted on alluvial soils (Typic Eutrochrept) of eastern India by adopting inductive cum targeted yield model to assess the fertility status, fertilizer requirements, and formulation with and without integrated plant nutrient supply fertilizer (IPNS) prescription equation for jute fiber, rice grain, and garden pea on soil-test and yield target bases. By using yields, initial soil-test values, uptake of nutrients, and fertilizer doses applied, the basic data [viz., nutrient requirement (NR) and contributions of nutrients from soil (Cs), fertilizers (Cf), and farmyard manure (Cfym)] were computed and used to develop fertilizer prescription equations for jute fiber, rice grain, and garden pea with and without IPNS under a jute-rice-garden pea sequence. The greatest nutrient requirement was observed in jute [2.88:0.97:5.07 kg nitrogen (N)/phosphorus (P)/potassium (K)] followed by rice (2.34:0.47:3.48 kg N/P/K) and garden pea (0.52:0.11:0.39 kg N/P/K) for the production of 100 kg yields of jute fiber/rice grain/green pod, respectively. It was found that soil has contributed the greatest percentage of N (20.6%) and K (47.29%) toward the total N and K uptake by rice followed in jute whereas the greatest percentage contribution of P (21.1%) occurred in jute. However, the greatest contribution of N, P, and K from the fertilizer was observed in jute, followed by rice and garden pea. Nitrogen contribution from fertilizer was 12.5 and 42.9% greater in jute than rice and garden pea, respectively. The greatest fiber and green pod yield in jute were recorded in the high-fertility gradient (strip III), whereas maximum rice grain yield was observed in the low-fertility gradient (strip I), which clearly indicated that high-fertility status favored the production of jute and garden pea but low-fertility status is suitable for rice production. By following ready table, a farmer can save N, phosphorus pentoxide (P 2 O 5 ), and dipotassium oxide (K 2 O) in amounts of 3. 21, 9.93, and 10.94; 6.35, 7.00, and 9.15; and 34.0, 26.0, and 34.4% more as compared to without IPNS respectively in jute, rice, and garden pea. Application of farmyard manure (FYM) in different fertility gradients improved the organic carbon (C) and available N, P, and K with increasing fertility.

Soil Test Based Fertilizer Application Improves Productivity, Profitability and Nutrient Use Efficiency of Rice (Oryza sativa L.) under Direct Seeded Condition

“…The NR for K was 1.52 and 6.95 times higher than N and P, respectively. Similar results were also reported by [48] 16.80, respectively, for N, P, and K was found. The contribution of nutrients from the fertilizer was high compared to the contribution from the soil, owing to having a higher and rapid nutrient availability in the inorganic form from the fertilizers.…”

“…Harnessing the potential yields of high yielding varieties of crops requires the application of optimum doses of nutrients [15]. However, an inadequate and imbalanced fertilizer use for crop production, without proper knowledge of the inherent soil capabilities and crop requirements, is also one of the causes that prevent gaining the full yield potential of crops and the deterioration of soil health, as well as economic losses to farmers [8,16], and often resulting in an adverse impact on crops and the soil, in terms of nutrient toxicity and deficiency [8]. Furthermore, fertilizer use requires knowledge of the expected GY response, which depends upon the crop nutrient requirements, nutrient supply from indigenous sources, and the fate of fertilizers applied to the soil in the short and long term [17].…”

Effect of weed management practices on productivity and profitability of jute fibre

“…In addition to its biodegradability and its ability to be used as an annual renewable resource, the short growing period (100-120 days) of jute enables the farmers to fit the crop in the prevalent rice based cropping system during the pre-Kharif (summer) season even under rainfed condition. Jute also helps in the maintenance of the soil productivity as it adds significant amount of organic matter along with nutrients to the soil through leaf fall during its growth (Singh et al 2015). Among the various factors contributing to high production cost of jute, heavy weed infestation is a major one and manual weeding operation alone contributes to 16.3% of the total production cost (Ghimire and Thakur 2013).…”

Impact of balanced fertilization on nutrient acquisition, fibre yield of jute and soil quality in New Gangetic alluvial soils of India

“…It enhances the delivery system of nutrient at critical growth stages of crops and reduces non-point pollution of surface and underground water. Fertilizers application largely depends on the status of available nutrient in the soil and nutrient requirement of crops as per targeted yield (Singh et al, 2015). Soil testing is an important tool for assessing inherent nutrient supplying capacity of a soil and recommendation of inorganic fertilizers to different crops.…”
