Some of the secondary and micro nutrients omission may not have reduced the yield from the maximum yield statistically significant manner however; such nutrients can be treated as hidden hunger and needs application for maximum yield.…”

The investigation was carried out with the aim to identify the specific yield limiting nutrients through response of rice to nutrient omission in pot culture under completely randomized design with 3 replications and 11 treatments during kharif season 2017 and to demonstrate the optimum use of identified limiting nutrients in wheat crop at field level in Kondagaon district during rabi season 2017-18. The treatments were formulated by keeping one treatment with application of all nutrients in optimum level and others by sequentially omitting each nutrient. The soil had a clay loam texture, neutral reaction (pH 6.6), normal electrical conductivity, medium organic C, available P and K, low available N and S, high available Ca, Mg, Fe, Mn and Cu and marginal available Zn and B. Omission of N and P nutrients significantly reduced the growth, yield and nutrients uptake by rice in comparison to all nutrients. The maximum grain yield of 73.0 g pot-1 was recorded, in all nutrients pot and 50.1 % reduction in grain yield of rice, from the maximum yield, was recorded in N omitted pots, followed by 18.8 % reduction in P omitted pots and omission of other nutrients didn’t reduce the grain yield significantly indicating that only N and P were yield limiting nutrients. In field verification during rabi season, 19.0 % increase in wheat grain yield and 23.0 % increase in net return was recorded, due to optimum dose of identified yield limiting nutrients over farmer's practice dose. The results clearly indicate that the site specific nutrient management dose based on yield limiting nutrient identified through nutrient omission study was found economically profitable to the farmers.

“…Phosphorous application increases P uptake, leading to increased tuber numbers and yields, and thus is the reason for reduced yields from NPKSB by over 15% with P omission. Omission of P has been found to affect the uptake of most of the essential plant nutrients on acidic to slightly acidic soils (Adalton Mazetti Fernandes et al, 2017;Borges et al, 2016;Kumar et al, 2018); this in turn affects most plant processes, thus reducing the yield. Higher uptake of N, K, Ca, Mg, S, B, Cu and Fe has been associated with P fertilization as a result of its effect on plant biomass (Fernandes et al, 2015;Fernandes et al, 2017;Soratto et al, 2020).…”

Low nutrients have been reported in potato-growing areas of Kenya, prompting a need for nutrient management research. A study was designed to determine the effect of omitting nutrients on potato growth, yield and harvest index. On-farm nutrient omission trials were set during the long rains (LR) and short rains (SR) of 2016 in which the treatments involve the judicious omission of N, P, K, S and B. Additional two treatments were included with one receiving all the nutrients and a control where no nutrients were added. The treatment was laid in a randomized complete block design with three replications. Potato yields reduced by 6.6 and 11.2 t ha −1 in N-omitted treatments in LR and SR, respectively, when compared to the one receiving all the nutrients, while omitting P resulted in respective yield reductions of 3.8 and 2.0 t ha −1 . Stability analysis revealed that omission of N was more stable with a regression coefficient of 0.5; it was followed by P with a value of 1. Potassium, S and B were limiting nutrients only in some farms. N and P should continue to be included in potato nutrient management, while K, S and B should be added based on soil test.

Crop management through site‐specific fertility methods is crucial for both economic and environmental benefits. Potato‐specific fertilizer has not been fully established in Kenya, and the current fertilizer recommendation has been in place for a long time. A study was designed through soil sampling from small‐scale farms to make a soil‐based fertilizer recommendation for potato production. Inverse distance weighting interpolation was used to study spatial distribution of pH and major nutrients. Cluster analysis was used to group sampled farms into similar fertility clusters for easier fertilizer recommendations. Spatial distribution maps were identified for the project area. Three and four clusters were established in Meru and Nyandarua counties, respectively, among which three had adequate nutrients for potato production. At least 150 kg N ha−1 is recommended in most of the farms and 160 kg P ha−1 in Nyandarua, while 285 kg K ha−1 was recommended in one of the clusters (nitrogen, phosporus, potassium [NPK] 1:1:1.5). Cluster analysis can be used to enhance fertilizer recommendations. The assumption that K is adequate in tropical soil should not be generalized. Fertilizers in the market with formulations close to the recommended ones should be evaluated for field performances and adjustment of the final potato fertilizer.
