Validation of Soil Test and Yield Target based Fertilizer Prescription Model for Rice on Inceptisol of Eastern Zone of Uttar Pradesh, India

Validation of Soil Test and Yield Target Based Fertiliser Prescription Model for Hybrid Maize on Vertisol

“…The highest BCR was recorded in STCR-IPNS-11 t ha -1 (2.28). Similar results were also reported by Manish Singh et al, (2017). The increase in yield due to STCR-IPNS-11 t ha -1 was 39.8 per cent over blanket (100% RDF), 18 per cent over blanket+ FYM @12.5tha -1 and 59.0 per cent over farmer's practice (Table 2).…”

On-farm Fertility Management through Target Yield Approach for Sustenance of Tribal Farmers

“…The higher response of fertilizers observed in targeted yield treatments, due to more precise/balanced application of fertilizers as compared to imbalanced fertilization in farmer practice [10] and this study area under low to medium category in available K and farmers didn't apply potassium fertilizers, it might be the reason for low yields in farmers fields at Peddatanda as well as Sainapally tanda [11]. These results elucidated the beneficial effect of STCR-IPNS treatments on the yield of castor and maize crops [12,3].…”

“…Several approaches of fertilizer recommendations have been followed world over of which soil test crop response based fertilizer recommendation for specific yield target of crops is unique as it not only indicates soil test based balanced fertilizer recommendations but also the level of yield which farmers' can obtain with optimum crop management under favorable climatic conditions [2]. Under Soil Test Crop Response (STCR) approach, the fertilizer dose varies for each unit change in soil test value and balanced doses are recommended for higher targets [3]. A systematic study on the effect of soil test crop response based fertilizer recommendations for specific yield targets of Castor and Maize in Nagarkurnool district is lacking.…”

Validation of Targeted Yield Equations for Finger Millet under Southern Dry Zone of Karnataka

“…lso, there might be favorable complementary influence of organics and inorganics on soil properties under STCR integrated approach wo ld ha e res lted in higher ield" [12]. " he higher grain yield in STCR treatments could also be attributed to the ability of targeted yield approach to supply the nutrient demand of crop more efficiently as it considers the nutrient requirement of the crop and contribution of nutrients from soil, fertilizers and organic manures and it discourages lop sized application of n trient or o er fertili ation" [13]. " en tho gh lower dose or no potassium fertilizer was applied in STCR treatments at both the targets as per the equations due to sufficient quantity of potassium in soils, the higher yield was recorded compared to Soil test laboratory approach and General recommended dose receiving higher amount of potassium fertilizer which clearly indicate that higher K application can be avoided by applying only the required quantity of fertilizer based on soil test and targeted yield approach of fertilizer recommendation so that unnecessary over-dose application at high available potassium soils can be restricted" [14].…”
