“…The increase in number of branches after first harvest at 3 WAT was as a result of apical dominance removal which resulted in new branch flushes. Ogar and Asiegbu (2005) reported high leaf yield and number of branches in fluted pumpkin as a result of apical dominance removal. The reduced increase in these plant parts from 5 to 7 WAT suggested increased deposit in the vine portion which resulted in improved vine diameter and length.…”

The variability among 18 accessions of Telfairia occidentalis were studied by examining their yield and yield component traits. The 18 accessions were collected from four local government areas in Enugu State, Nigeria. The experiment was performed in a randomized complete block design replicated three times. Ih-M accession gave the highest fruit circumference and average fruit weight that was significantly higher than Ih-L accession. Ib-S accession gave the highest total fruit weight and number of fruits per hectare. The PCA result showed that the first three principal components explained 86.91% of the total variation. The dendrogram grouped the fluted pumpkin accessions into three major clusters at similarity coefficient of 0.80. The cluster means showed that cluster I gave the highest number of days to first male anthesis and number of leaves per vine length of 40 cm. Cluster II gave the shortest number of days to male and female anthesis. It gave the highest total marketable leaf yield, number and length of the vine, width and length of the terminal leaflet. Cluster III gave the highest total and average fruit weights, number of fruits, fruit length and circumference, vine diameter, number of leaves per plant, fresh and dry leaf:vine ratio. The results indicated that the reproductive and yield traits assessed had significant contributions towards fluted pumpkin diversity. This information is vital for conservation of different genetic materials and initiation of improvement programme for T. occidentalis in Nigeria.

“…Research has shown that some production techniques could affect fluted pumpkin yield. These include time of sowing (Asiegbu ), tillage practice (Awodun ), manure rate (Ogar and Asiegbu ; Awodun ), plant staking (Egun ; Chukwudi and Agbo ), and cutting frequency (Ogar and Asiegbu ; Chukwudi and Agbo ). In Nigerian savanna where bulk of agriculture is done, low status of plant nutrients and poor soil physical condition constitute serious agronomic constraints (Salako ).…”

Fluted pumpkin (Telfairia occidentalis) has high agronomic and food relevance in the tropics. Production of this vegetable in the dry season with irrigation is increasingly popular and is mostly on droughty soils, thus requiring research on appropriate combination of soil moisture conservation/management practices. This study evaluated the interactions among seedbed configuration (flat and raised), surface mulching (grass‐mulched and no‐mulch) and plant spacing (1002, 502 and 252 cm2, designated wide, intermediate and close spacing, respectively) on fluted pumpkin performance in a sandy‐loam soil in southeastern Nigeria during 2014/2015 dry season. Seedling emergence (ratio of emerged to expected seedlings) was highest and lowest in flat/mulched/wide and flat/no‐mulch/close combinations, respectively. Main effects showed higher seedling emergence in mulched (67.9%) than no‐mulch plots (53.1%) and in wide (70.8%) and intermediate spacing (64.6%) compared to close spacing (46.0%). Fresh leaf yield assessed biweekly during 6–14 weeks after sowing was generally highest and lowest in flat/mulched/close and flat/no‐mulch/wide combinations, respectively. Seedbed configuration had no distinct effect on leaf yield; hence, flat/mulched/close option was similar to raised/mulched/close option. Yields from mulched/wide and no‐mulch/close options were similar with a mean (2735 kg/ha) approximating the overall mean (2868 kg/ha). Flat/mulched/close combination is the best management practice to grow fluted pumpkin with irrigation on droughty soils during the dry season of the tropics. Where this best practice is compromised due to mulch or seed scarcity, the ensuing no‐mulch/close and mulched/wide, respectively can support dry‐season production of pumpkin in droughty tropical soils at average levels.

“…Meanwhile, the highest number of fruit per plant, fruit weight per plant and fruit yield recorded by the highest amount of fertilizers rates could be explained by the favourable impact of fertilization on fruit process production [9,10]. This increase in productivity of plants according to fertilizer rates was also shown by Vijaya and Halakshmi [11].…”

Three African eggplant (Solanum spp.) varieties were assessed in six mineral manures doses T + 1/2T, T + 1/4T, T, T -1/4T, T -1/2T and without fertilizer, with reference treatment T = 300 kg/ha of NPK 10-18-18 applied before transplanting + a mixture of 100 kg/ha of urea and 200 kg/ha of potassium sulphate at 30, 60 and 90 d after transplanting, to establish fertilization protocol for their cultivation. The experiment was laid out in split-plot design with three replications with varieties constituting the main factor and the fertilizer doses as secondary factor. The main observed parameters were the number of days to 50% flowering, the fruit number and weight per plant, individual fruit weight and fruit yields. As results, the interaction between varieties and fertilizer doses was significantly different only for the number of days to 50% of flowering (P = 0.0078) and the fruit number per plant (P = 0.0001), while any significant difference was observed for individual fruit weight (P = 0.64), fruit weight per plant (P = 0.74) and fruit yields (P = 0.74). The difference among the fertilizers treatments was significant for the number of days to flowering, number of fruits per plant, fruit weight per plant and fruit yield for Aub33K/06Gn and Aub55N/10K, whereas any significant difference was observed for these parameters concerning Aub21N/06Du. Whatever the variety, there was not any significant difference among the fertilizers treatments for the individual fruit weight. For Aub33K/06Gn and Aub55N/10K cultivation, the fertilizers doses T -1/4T and T -1/2T are suggested, respectively, while a specific study is proposed for Aub21N/06Du. As perspective, economic studies are proposed to confirm the above suggested choices of fertilizers rates.
