“…This indicated a reduction in seasonal rainfall patterns due to low and erratic rainfall and high temperatures recorded during the second season. Muthoni et al (2017) and Waaswa et al (2021) reported a significant reduction in in-season rainfall followed by an uneven distribution of rainfall in Nakuru County, Kenya. This demonstrated the need for supplemental irrigation in the potato growing area of Nakuru county.…”

Background Low soil fertility and reduced seasonal rainfall contribute to low potato (Solanum tuberosum L.) yield in Kenya. Nitrogen (N) deficiency is the major problem facing by the smallholder farmers of Kenya due to lack of fallow. Hence an introduction of supplemental irrigation with an adequate application of this nutrient could increase potato yield. The objective of this study was to determine the effects of supplemental irrigation and N-fertilisation on potato tuber yield, water use efficiency (WUE) and nitrogen use efficiency (NUE). The experiment was conducted in Nakuru County, Kenya for two seasons. The experimental soils are classified as mollic Andosols. The treatments comprised two irrigation treatments of full supplemental irrigation (FI) and rainfed production (RF) and four N levels of four N levels of 0 (N0), 60 (N1), 90 (N2) and 130 kg N/ha (N3). Results The results showed that total tuber yield, marketable tuber yield and NUE were significantly (P < 0.001) affected by irrigation × N-fertilisation while WUE was only affected (P < 0.001) by N-fertilisation. The highest total tuber yield, 58.28 tonnes/hectare (t/ha), was recorded under FI combined with N3. Treatment FI significantly increased marketable tuber yield by approximately 125.58% in all N treatments compared to RF. The highest NUE of potato (236.44 kg/kg of N) was obtained under FI combined with N3 but not significantly different from the NUE of potato obtained under FI with N2. N-fertilisation N3 produced the highest WUE of 14.24 kg/m3. Significant correlation was obtained between tuber yield and number of tubers/plant (r = 0.75, P < 0.001), NUE (r = 0.95, P < 0.001) and WUE (r = 0.72, P < 0.001). Conclusion High potato yield and marketable tuber yield can be achieved in mollic Andosols when water deficits of the growing season are eliminated with supplemental irrigation and an application of 130 kg N/ha.

“…Public, private, and non-profit development agencies have broadened their scope to cushion farmers against the climate change effects, more so on the smallholder farmers in Africa where the magnitude of the effect is exorbitant ( Alliagbor et al., 2020 ; Derbile et al., 2021 ). Dissemination and practice of climate-smart agricultural practices (CSAPs) are principal strategies to cope with the impacts of climate change ( Alliagbor et al., 2020 ; Waaswa et al., 2021 ). The practice of CSAPs portrays the potential to boost and sustain agricultural productivity and improve farmers’ resilience to climate change shocks ( Arslan et al., 2014 ; García de Jalón et al., 2017 ; Martey et al., 2021 ).…”

“…This study defined CSAPs as any common farming production practice that has been reliably examined and deemed most reliable in reducing or dismissing climate change effects on a given system, especially in potato production. Examples of CSAPs entail but not limited to (i) drought-tolerant and high-yielding crop varieties, (ii) synthetic fertilizers, (iii) rainwater harvesting and storage, (iv) agroforestry, (v) irrigation, (vi) mulching, (v) composting, (vii) terracing, (viii) potato apical rooted cuttings (potato seedlings), (ix) potato minitubers, (x) crop rotation, (xii) intercropping, (xiii) drainage management and (xiv) minimum tillage ( Waaswa et al., 2021 , p. 6). Since the rebranding of some agricultural practices into CSAPs, some farmers react to climate change by practicing these CSAPs on their farms ( Nyongesa et al., 2019 ; Wekesa et al., 2018 ).…”

Proven and sustainable practices like climate-smart agricultural practices (CSAPs) need to be prioritized and promoted for uptake especially by the farmers to achieve sustainable development. These are capable of contributing to the realization of sustainable development goals through averting food and nutritional insecurity, increasing and sustaining yields that translate into increased incomes and later reduced poverty. This is because CSAPs enable farmers to adapt and mitigate climate change effects. However, due to inappropriate communication of CSAPs to the farmers, to date, some farmers still see no escape route from the frightening effects of climate change and they are currently adopting a rather fatalistic attitude. This study investigated the information dissemination pathways used by different categories of smallholder potato farmers for and practice of CSAPs. It found a difference between information sources and practice of CSAPs at a 5% level of significance (χ2 = 100.12139, df = 2, p < 0.05, Cramer's V = 1.0), and a difference in the use of the three information dissemination pathways between men and women at a 5% level of significance (χ2 = 6.05949, df = 2, p < 0.05, Cramer's V = 0.17406). The three information dissemination pathways included media, neighbors and friends, and extension officers. Generally, farmers were aware and practiced the CSAPs investigated in this study except for irrigation with high awareness yet with low uptake percentage and potato seedlings and minitubers both with low awareness and practice respectively. This study recommended mainstreaming of CSAPs information.

“…Also, this study provides knowledge on N management in potato using GreenSeeker sensor and CM-100 chlorophyll meter, considering that N is the most limiting nutrient of potato yield. The greater demand for potato due to the growing population moreover in the face of climate change (Waaswa et al, 2021) and this coupled with the difficulty in N management in potato justifies the need for new and quick access methods of N status in potato production. Thus farmers who might apply this knowledge could be able to access N status at different growth stages of potato growth and hence being in position to match the crop requirements with the N supply.…”

This study evaluated the possibility of the use of GreenSeeker sensor and CM-100 chlorophyll content meter for in-season N and yield prediction in order to promote timely split N application in potato production in Kenya. Four N-fertilization rates; N0 (0), N1 (60), N2 (90) and N3 (130 kg N/ha) were led out in a Randomized Complete Block Design (RCBD) in a Greenhouse for two seasons. The results showed that % N leaf content was significantly affected by N rates. The % N leaf content and potato leaf chlorophyll content decreased as the season continued whereas the Normalized Difference Vegetation Index (NDVI) increased as the season continued. CM-100 values were significantly correlated with % N leaf content at vegetative (r=0.86***) and tuber initiation (r=0.74***) growth stages of the crop whereas the NDVI values were only significantly correlated with % N leaf at tuber initiation (r=0.82***). A significant relationship was found between CM-100 values taken at different potato stages (end of vegetative, tuber initiation, bulking and maturation stages) and tuber yield (r=0.90***, 0.82***, 0.47* and 0.41*). The NDVI values at end of vegetative growth, tuber initiation and maturation of potato were also significantly correlated with tuber yield (r=0.81***, 0.43* and 0.54*), except at bulking stage (r=0.33). For efficient in-season N management and yield prediction, CM-100 and GreenSeeker are recommended at an early stage of the crop. Further research in the different potato growing areas in Kenya to establish the different thresholds at different potato growth stages is recommended.
