“…Also, rice's higher grain yield response to N and K may be attributed to its high nutrient requirement. Our findings coincided with the observation of Sharma et al [29], who reported a close association between crop yields and nutrient uptake. Moreover, positive and significant correlations between grain yield and plant height (r = 0.87; p = <0.01), tiller number (r = 0.70; p = <0.01), panicle length (r = 0.74; p = <0.01), panicle weight (r = 0.73; p = <0.01), grain number panicle −1 (r = 0.80; p = <0.01), and straw yield (r = 0.74; p = <0.01) were observed.…”

A field experiment was conducted to determine the effects of organic and inorganic fertilizer applications on soil fertility, productivity, and rice profitability. There were five treatment combinations with four replications laid out in Randomized complete block design (RCBD). The treatments were as follows: T 1 : control, T 2 : farmer's practice (FP), T 3 : recommended rate (RR), T 4 : organic fertilizer (OF), and T 5 : RR 50% + OF 50% . RR 50% + OF 50% application significantly increased soil fertility after harvest. The N and K uptake of rice was also increased under FP and RR treatments. All yield components were increased with FP, RR, and RR 50% + OF 50% treatments, with the consistently highest increase in the FP treatment. The highest grain yield obtained was in FP (6.68 t ha −1 ) followed by RR (6.28 t ha −1 ), RR 50% + OF 50% (6.12 t ha −1 ), and OF (5.25 t ha −1 ), while the lowest yield was recorded in the control treatment (4.67 t ha −1 ). The net income was also increased by 43% in FP, 39% in RR, and 34% in RR 50% + OF 50% over the control. Maximum rice productivity and profitability were both obtained under FP. However, a similar yield and profit increase were also obtained in RR and RR 50% + OF 50% treatments. The results highlighted the importance of combining organic and chemical fertilizers to reduce the cost of fertilizer inputs, increase soil fertility, improve rice yield, and maximize profitability in rice production.

“…Net returns from the improved practice (STCR technology) were substantially higher than the FP for DSR. Similarly, higher indices of economic analysis, such as gross and net return and benefit:cost ratio, than the GRD in transplanted rice under rainfed Alfisols have been noticed [15]. The highest economic efficiency was recorded with STCR TY2 (INR 285 ha −1 d −1 ), which was due to the highest net return being obtained under this treatment (Table 10).…”

“…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].…”

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.

“…It was estimated that 55% of the increase in food comes from the influence of fertilizers [12]. However, it was known that 2 /3 of used N fertilizer can be lost through washing, evaporation, denitrification, and carried away by runoff [13,14]; so that in rice cultivation, N efficiency is very low, like P fertilizers. After P nutrients is given, dissolution occurs.…”

Soils in riparian swampland are considered marginal and have low nutrient contents. A research on the validation of fertilizer recommendations as a complement to Swamp Soil Test Kit (PUTR) was carried out on shallow inland swamps in Sungai Ambangan Village, Sungai Raya District, Kubu Raya Regency, West Kalimantan, during dry season of 2017. The treatments consisted of 1) complete control; 2) NPK local recommendations; 3) 1 1/2; of NPK PUTR recommendation + Dolomite; 4) NPK PUTR recommendation + Dolomite; 5) 2/3 of NPK PUTR recommendation + Dolomite; and 6) NPK of local farmer’s recommendation. Results using PUTR and laboratory equipment showed acidic soils with low to medium nitrogen, medium to high P, and low potassium. Validation showed that highest number of productive tillers was found in treatment of 1 1/2; of NPK PUTR recommendation + Dolomite. Plant height showed that there was insignificant difference between treatment with NPK local recommendation, 1 1/2; of NPK PUTR recommendation + Dolomite, NPK PUTR recommendation + Dolomite, 2/3 of NPK PUTR recommendation + Dolomite. This was similar to results of harvested dry grain and harvested grind grain. Utilization of PUTR as rapid test tool can be implemented for ricultivation on riparian swampland. Impact of fertilization obtained neck blast attack increased along with the rise of fertilization dose, especially nitrogen.
