“…This trend observed mainly because of the higher doses of the key nutrients N, P, and K, which are proven to enhance rice yield. Several researchers also reported the similar effect of key nutrients on plant growth and yield-attributed traits [85–88]. The variance components of FATs indicated that the segregation pattern at different DGI stages under different fertilizer doses varied from normal to skewed distribution (Table 2).…”

The production and productivity of rice ( Oryza sativa L.) are primarily influenced by the application of the critical nutrients nitrogen (N), phosphorus (P), and potassium (K). However, excessive application of these fertilizers is detrimental to the environment and increases the cost of production. Hence, there is a need to develop varieties that simultaneously increase yields under both optimal and suboptimal rates of fertilizer application by maximizing nutrient use efficiency (NuUE). To unravel the hidden genetic variation and understand the molecular and physiological mechanisms of NuUE, three different mapping populations (MPs; BC 1 F 5 ) derived from three donors (Haoannong, Cheng-Hui 448, and Zhong 413) and recipient Weed Tolerant Rice 1 were developed. A total of three favorable agronomic traits (FATs) were considered as the measure of NuUE. Analysis of variance and descriptive statistics indicated the existence of genetic variation for NuUE and quantitative inheritance of FATs. The genotypic data from single-nucleotide polymorphism (SNP) markers from Tunable Genotyping-By-Sequencing (tGBS) and phenotypic values were used for locating the genomic regions conferring NuUE. A total of 19 quantitative trait loci (QTLs) were detected, out of which 11 QTLs were putative on eight chromosomes, which individually explained 17.02% to 34.85% of the phenotypic variation. Notably, qLC-II_1 and qLC-II_11 detected at zero fertilizer application showed higher performance for LC under zero percentage of NPK fertilizer. The remarkable findings of the present study are that the detected QTLs were associated in building tolerance to low/no nutrient application and six candidate genes on chromosomes 2 and 5 within these putative QTLs were found associated with low nutrient tolerance and related to several physiological and metabolic pathways involved in abiotic stress tolerance. The identified superior introgressed lines (ILs) and trait-associated genetic regions can be effectively used in marker-assisted selection (MAS) for NuUE breeding programs.

“…Thus, each T 2 treatment contained three (03) rows of Sorghum and four (04) rows of beans. Two weeks after sowing, 48 g of 20-10-10 were applied in T 1 treatment at the rate of 200 kg per hectare [20]. Four (04) seeds of Sorghum were sown in each hole, followed by a postemergent thinning.…”

Sorghum (Sorghum bicolor (L) Moench) is a staple food in Africa, South Asia and Central America. In Cameroon, it is the main food of the population of the Sudano-Sahelian zone. Its production could decline by up to 20% by the middle of the century, due to climatic disturbances. This climatic disturbance in Cameroon has led to several consequences among which, low crop yields. The comparative effect of the biological fixation of nitrogen and chemical fertilizer on the optimization of yield of two varieties of Sorghum, was conducted from July to October at IRAD (Institute of Agricultural Research for Development) station of Foumbot. The experimental design was a complete randomized block with two factors: varieties of sorghum (V1: S35 and V2: BIOGLOR) and treatments (T0: Control, T1: 20-10-10 and T2: Sorghum / NITU beans). The collar diameter, the number of leaves and plant height were evaluated each week and yield in the end of the cropping season. As a result, treatment T1 induced very significantly (P ˂ .01) growth (shoot length, leaf and collar diameter). T1 (V1: 1.30 ± 0.11 t.ha-1, V2: 2.01 ± 0.07 t.ha-1) and T2 (V1: 1.12 ± 0.02 t.ha-1, V2: 2.15 ± 0.03 t.ha-1) showed statistically equal yields, and significantly different from T0 (V1: 0.50 ± 0.06 t.ha-1, V2: 0.55 ± 0.05 t.ha-1). The BIOGLOR variety had the highest yield (1.57 ± 0.57 t.ha-1) compared to the S35 variety (0.97 ± 0.19 t.ha-1). The treatment T2 is the recommended fertilizer system because of the higher grain yield of sorghum and its ability to protect the environment.

“…Thus, an increase in K is associated with vigorous plant growth. Djomo et al [21] reported the same increase in plant height by applying the different doses of fertilizers using NPK. Rishikesh et al [22] have also reported a significant increase in plant height with applied NPK fertilizer based on soil tests with or without farmyard manure.…”

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.
