| dc.description.abstract | A field experiment was started since 2018-19 in the D7 block of Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. This thesis work is presented for the year 2021-22, on a comparison of soil test crop response and the GRD approach for fertilizer recommendation in maize–wheat crop rotation. For this experiment a hybrid maize variety (P3401) grown in the kharif season of the year 2021 and a wheat variety (HD 2967) grown in the rabi season of the year 2021-22. The experiment was carried out with three replications and nine treatments in a randomized block design and used treatments were control (T1), GRD (T2), STCR target yield (inorganic mode) (T3), STCR INM mode (T4), 75% STCR dose of N (inorganic mode) + green manure (T5), 50% STCR dose of N (inorganic mode) + green manure (T6), 75% RDN + green manure (T7), 50% RDN + green manure (T8) and FYM + green manure + urd intercropping (T9). It was observed that the residual impact of green manure (Sesbania) was seen only on the wheat crop during the kharif season because the crop was grown on-site, cut and incorporated into the soil during this time period only. There was only intercropping of urd between the rows of maize crops. The grain and straw yields for each plot were recorded after harvest. The plants and soil samples were collected at the end of each cropping season and analyzed according to standard methods. The experiments revealed that both inorganic fertilizers and organic manures (FYM and green manure incorporation) had no significant impact on soil pH and EC. STCR-based approach improved the mineralization of nitrogen, the extraction of phosphorus and the extraction of potassium from the soil. There was a variation in the maize yield between 29.33 q ha-1 and 57.47 q ha-1 during kharif 2021. Wheat grain yields ranged from 28.61 q ha-1 to 49.39 q ha-1 during rabi 2021-22. The crop had higher grain yields and nitrogen, phosphorus and potassium uptake after using 100% STCR-based fertilizers with FYM @ 10 t ha-1. A higher percentage of target yield was also achieved under the STCR INM approach than under NPK alone. STCR-based treatment that included STCR INM and 75% STCR dose of N + green manure had improved soil properties. It was concluded from the present experiment that fertilizer recommendations based on the Soil Test Crop Response approach combined with organic manure assist in the management of nutrients and reduce the use of excessive fertilizers, which restores soil fertility, maintains soil health and environmental quality by reducing excessive fertilizer consumption | en_US |
