“…The variations observed in the fruit length, fruit circumference, rind fresh weight and juice-to-fruit ratio between the two yellow passion fruit genotypes confirmed that the hybrid, KPF-4 are bigger in size as reported by KARLOS (2014). The present study is also in agreement with the report of Ndukwe and Baiyeri (2018a). However, the bigger size of the KPF-4 was not translated to higher juice percentage as claimed by KARLOS (2014).…”

“…Realizing the importance of passion fruit, the Kenya Agricultural Research and Livestock Organization (KARLO) developed KPF-4 among other two (KPF 11 and KPF 12) hybrids (KARLOS, 2014) and were released in 2011. Mwirigi et al (2016) noted that KPF-4 has higher preference than the other two hybrids as it has higher fruit The choice of combining organic and inorganic fertilizers in the 2016 was because of superior and sustainable performance of passion fruit as regards growth and fruit yield with 20 t ha -1 poultry manure application over other PM rates (Ndukwe and Baiyeri, 2018a). In both crop cycles, the experimental layout was split-plot replicated three times.…”

An investigation was undertaken to determine the fruit and juice metric traits of fresh fruits obtained from two yellow passion fruit genotypes grown in south-eastern Nigeria in two seasons. The passion fruit genotypes (Conventional and KPF-4) received 0, 10, 20, 30, 40 t ha-1 poultry manure (PM) rates in 2014 and 0, 10, 20 t ha-1 PM, 5 t ha-1 PM + 200 kg ha-1 NPK 15:15:15, 10 t ha-1 PM + 200 kg ha-1 NPK and 400 kg ha-1 NPK in 2016. Ten ripe and freshly dropped fruits in 2015 and 2017 were picked and taken to the laboratory. Fruit and juice metric traits (such as fruit length, circumference, pulp weight, juice volume and weight) were measured. Data collected were subjected to analysis of variance following the procedure for split-plot experiment in completely randomized design. KPF-4 significantly (p<0.05) produced longer, wider and heavier fruits than the Conventional in 2015 whereas in 2017 all the fruit metric traits did not significantly (p>0.05) differ between the genotypes. Juice volume (682 ml) and pulp fresh weight (942 g) in 2015 were significantly highest in the Conventional when they received 20 or 40 t ha-1 PM. Application of 10 t ha-1 PM + 200 kg ha-1 NPK in 2016 enhanced the production of highest juice volume (723 ml) and pulp fresh weight (770 g) in the Conventional. Juice percentage and fruit metric traits of yellow passion fruit could be enhanced with the application 20 t ha-1 PM, considering lesser cost of PM procurement, or combined application of 10 t ha-1 PM + 200 kg ha-1 NPK.

“…According to Karani-Gichimu et al (2013), manure is one of the production factors that has the highest effect on the productivity of purple passion fruit in the Central-Eastern and North-Rift regions of Kenya. Previous studies on the effect of poultry manure (PM) rates on the growth, fruit and juice yield of yellow passion fruit in Nsukka, south-eastern Nigeria revealed that 15 to 20 t/ha poultry manure application produced optimum growth, fruit and juice yield (Ani & Baiyeri 2008;Ndukwe & Baiyeri 2018a, 2018b. In another study carried out in Nsukka, the nutritional quality of passion fruit juice was best from passion fruit vines that received a combined application of 10 t/ha poultry manure + 200 kg/ha NPK 15:15:15 (Ndukwe & Baiyeri 2018c).…”

Three experiments were conducted from 2014 to 2018 to examine the economics of yellow passion fruit production under different soil fertility management. In 2014, two yellow passion fruit genotypes, that is Conventional and KPF 4, were grown in the field and pot simultaneously under varying rates of poultry manure (PM), including 0, 10, 20, 30 and 40 t/ha. In 2016, the response of the two genotypes to a single and combined application of organic and inorganic fertilisers was evaluated under field conditions, namely no fertiliser application, 10, 20 t/ha PM, 400 kg/ha NPK 15:15:15, 5 t/ha PM + 200 kg/ha NPK, and 10 t/ha PM + 200 kg/ha NPK. The profitability indicators were gross revenue, net revenue, returns per naira invested and the profitability index. In 2014, total variable cost increased significantly (P < 0.05) with an increase in PM rates in both the field and pot studies. The highest net returns and returns per naira invested were obtained with the application of 20 t/ha PM. The combined application of 10 t/ha PM + 200 kg/ha NPK recorded the highest gross return, net return and return per naira invested in the 2016 production cycle. Growing the vines without fertiliser application gave significantly least net returns without profit in both production cycles and methods. Consequently, applying 20 t/ha PM was adjudged the most profitable for yellow passion fruit production in the study area, and hence is recommended particularly when organic farming is intended. However, if growers must use inorganic fertiliser, a combined application of 10 t/ha PM + 200 kg/ha NPK will be most profitable.

The increasing global concern about ecologically unsafe agricultural practices calls for an investigation of how fertilizer combinations and harvest age interact to influence the biochemical qualities of crops. The study objective was to determine the biochemical responses of three carrot varieties to fertilizer composition, and harvest-age interactions. Three carrot varieties, Graffas, Carrot Touchon, and Nantes; four fertilizer compositions, 10 t/ha of poultry manure + 200 kg of NPK 15:15:15 (PM10 + NPK200), 20 t/ha of pig manure + 200 kg of NPK 15:15:15 (PIG20 + NPK200), 350 kg of NPK 15:15:15 (NPK350), and 0 t/ha (control); and three harvest-age, 10, 12, and 14 weeks after planting (WAP) were evaluated in a 3 x 4 x 3 factorial in randomized complete block design with 3 replications. Variations in biochemical concentrations of carrot roots with variety, fertilizer type, and harvest-age interactions were recorded. Proximate qualities were generally higher in Nantes and Graffas varieties grown with the combined use of organic and inorganic fertilizers harvested at 10 WAP. Phytochemical quality was higher in Graffas and Carrot Touchon grown with PM10 + NPK200 when harvested at 14 WAP. Nantes variety grown with NPK350 and harvested at 12 WAP had higher vitamin contents. Root weight had a positive correlation with saponin (0.22), carbohydrate (0.31), alkaloid (0.33), vitamin E (0.26), and fiber (0.19). Vitamin C displayed positive correlations with vitamin B (0.43), vitamin E (0.56), alkaloid (0.67), tannin (0.31), saponin (0.32), and carbohydrate (0.35), while beta-carotene exhibited positive correlations with vitamin A (0.42) and tannin (0.38).
