A field investigation on direct seeded rice (DSR) was carried out in the two consecutive rice growing seasons of 2017 and 2018 at Pantnagar, Uttarakhand, India for the development and validation of soil test crop response (STCR) to fertilizer and for assessing the performance of STCR-treatments as compared to the general recommended dose (GRD) in terms of yield, nutrient uptake and use efficiency, and the economics of DSR. For producing 1 Mg of rice-grain, the required nutrients (N, P, and K) were 2.01 kg, 0.44 kg, and 3.06 kg; the contribution from the soil was 22.05%, 37.34%, and 41.48%; from applied farmyard manure 23.25%, 28.34%, and 16.80%, from fertilizer 38.08%, 49.93%, and 252.98%; and from fertilizer with FYM 44.83%, 60.57%, and 278.70%; for N, P, and K, respectively. The STCR approach, with or without FYM, at both the target yields (4.5 Mg ha−1 and 5.0 Mg ha−1) markedly enhanced the grain yield (20.2% to 32.3%) and production efficiency over the GRD. It also exhibited a higher NPK uptake and use efficiency, along with better profitability, than the GRD. Therefore, the STCR-targeted yield approach could improve the yield, economics, and efficiency of nutrient use for direct seeded rice.

“…As a quick‐acting fertilizer, chemical fertilizer can support the nutritional needs of rice in the early stage of growth, while organic fertilizer has complete nutrients and a long fertilizer effect, which is of great significance for the later growth of rice and the improvement of crop yield and quality (Ansari & Mahmood, 2017; Majhi et al, 2019; Subedi & Ma, 2005). This study shows that the yield of the high organic fertilizer ratio under controlled irrigation reaches the highest yield, and the yield of rice will increase with the increase in the organic fertilizer application ratio.…”

Water and fertilizer management practices are critical in rice fields. Excessive application of fertilizer adversely affects soil physicochemical properties, consequently decreasing yield. A greenhouse experiment was conducted to determine the effect of high (L1), medium (L2) and low organic fertilizer ratios (L3) as well as chemical fertilizer alone (L4) and no fertilization (L5) under conventional (C) and controlled irrigation (M) on rice yield and soil characteristics. Statistically, the regression equation was developed by using principal component analysis to clarify the influence of different soil quality factors on rice yield. The results showed that controlled irrigation could increase soil temperature (ST), electrical conductivity (EC) and nitrogen content while decreasing soil pH. The application of organic fertilizer enhanced ST and decreased EC. Under equal nitrogen application conditions, rice yield increased with organic fertilizer application, and it was highest under L1, which was 2.7% higher than L4 and 22% higher than L5. In the case of irrigation methods, controlled irrigation application increased yield by 6% compared to conventional irrigation. The multiple linear regression equation showed that the cumulative contribution of variance of the two principal component eigenvalues reached 75%, among which soil pH, total nitrogen (TN) content and nitrate nitrogen (NO3−‐N) contributed positively to yield, while ammonium nitrogen (NH4+‐N), soil organic carbon (SOC), EC and ST showed negative effects on rice yield. Thus, our study findings can provide a scientific basis for improving management practices.

“…As the soils of the present study belonged to the lower IGP of India, most of the scientific literatures pertaining to soil quality research (Biswas et al, 2017; Majhi et al, 2019) are focussed on the dominant cropping systems (rice‐rice and rice‐wheat) of the region. A systemic study on the effect of medium‐term conservation agricultural practices on soil quality of semiarid and hot climate (northwestern IGP) under rice‐mustard of cropping system was performed by Das et al (2021).…”

Deterioration of soil quality under resource-intensive modern agriculture in the face of global climate change poses a huge risk to food security. Because of the complex nature, estimators of soil quality often rely upon a limited set of soil attributes, along with statistical data reduction techniques, for developing quality indices, whilst overlooking biological aspects and regional climatic variability. This study screened the most suitable soil quality indexing approaches for a rice-oilseed-based cropping system in the lower Indo-Gangetic plains (IGP).For this, surface soil samples (0-15 cm) were collected from an ongoing longterm fertilizer experiment with a rice-mustard-sesame cropping system in the IGP. The following treatments were assessed for their effect on soil quality: T 1control, T 2 -NPK (recommended NPK doses), T 3 -NPKG (NPK + in situ green manuring), T 4 -NPKGB (NPK + in situ green manuring + biofertilizer) and T 5 -NPKF (NPK + farm yard manure FYM). We found that total organic carbon (TOC), βglucosidase, CaCl 2 extractable S, alkaline KMnO 4 oxidizable N, activity of urease, amidase enzyme and mean weight diameter (MWD) were sensitive key indicators of soil quality. The NPKF treatment maintained the highest soil quality status (0.80-0.91), both under productivity and environmental protection goals, owing to the availability of decomposable carbon. Regression analysis showed a better agreement of equivalent rice yield with expert opinion (EO; R 2 = 0.89) than principal component analysis (PCA; R 2 = 0.76). Finally, we found that the expert opinion approach with the nonlinear scoring function was the best tool for soil quality assessment of the region.
