Effects of Biochar, Poultry Manure and Their Combined Application on Leaf Nutrient Concentrations, Root Storage Minerals, Growth and Yield of Sweet Potato (Ipomoea Batatas L.)

A field experiment was carried out on a farmer’s field at Kannitamilnadu village in Cuddalore district, Tamilnadu during 2018 to find out the suitable organic inputs and pattern of mulching for better growth and yield of roselle (Hibiscus sabdariffavar. sabdariffa). The experiment was laid out in a factorial randomized block design with five levels of organic manures and four levels of mulching with three replication.. Best of the interaction effect was due to the combined application of 25 t FYM + 3 t poultry manure ha-1+ plastic mulch (M3S2) which recorded the highest values for all growth and yield parameters viz., plant height (228.3 cm), number of branches (14.5), leaf area (308.9 cm2), number of calcyes/plant (33.5), calyx yield/plant (233.9 g) and calyx yield/ha (6568.75 kg). The lowest values of these parameters were recorded under control (no organics and no mulching) treatment

In Côte d’Ivoire, the sweet potato is little cultivated but stays however a culture of pension and a food mattering in certain regions. This study was conducted to assess the effect of the application of mineral (NPK 15-15-15, NPK 12-22-22) and organic (poultry manure) fertilizers on yield components of sweet potato (Ipomoea batatas (L) Lam). The experiment was conducted over two years (2016 to 2017) in experimental station of National Center of Agronomic Research (CNRA) of Bouaké in the centre of Côte d'Ivoire. The experiment was conducted following a split plot with 2 factors (variety and fertilizers) and 3 replicates. The main factor was variety with 2 levels (variety Irene and variety TIB-440060) and the subplot was fertilizers application consisted 13 levels (200, 300, 400, 500 kg ha-1 of NPK fertilizers combined 5, 10, 15 t ha-1 of organic fertilizer). Thirteen treatments based on poultry manure (T6, T7), chemical fertilizer NPK 15 15 15 (T1, T3, T4, T5) and NPK 12 22 22 (T8, T10, T11, T12) and their combination (T2 and T9) were tested. The experimental results revealed that that the effects of chemical fertilizer treatments, manure and their combination with mineral fertilizers did not influence the measured parameters. The results also showed that fertilizers improved all the agronomic parameters of sweet potato compared to the control treatment during two years of experiment. However, the Irene variety with a mean weight of 180 g tuberous roots was significantly different from the TIB variety with a mean weight of 138.73 g. In the conditions of our study and over the two-year period, producers of sweet potatoes would benefit from using organic fertilizers with the Irene variety.

Field trials were conducted at the University Orchard Aliero, Kebbi state University of Science and Technology Aliero, during the 2017 and 2018 dry seasons, to study the growth and yield of Okra (Abelmoschus esculentus L. Moench) varieties influenced by sole and combined application of NPK (15:15:15) and Poultry manure. The treatments consisted of a factorial combination of three Okra varieties: LD88, NHAE47-4 and Dogo; and three level of nutrients: 800 kg NPK (15:15:15) ha-1, 100%PM ha-1 equivalent to 6.6 t ha-1 and 50% NPK+50% PM ha-1 (400 kg of NPK [15:15:15] + 3.3 t of PM ha-1) and the untreated control, each designed to supply the recommended dose of 120 kg N ha-1 using a compound fertilizer NPK (15:15:15) and poultry manure and cow dung. Results revealed that plant height, number of leaves, number of pods per plant, mean pod weight (g), mean pod length (cm), fruit yield per hectare were significantly increased when the recommended N dose of 120 kg N ha-1 was applied using only NPK (800 kg NPK [15:15:15 ha-1]) or a combination of NPK+PM at 50:50 ratio in conjunction with variety NHAE47-4. Based on the results of this study, it could be concluded that the integration of organic and inorganic fertilizers in form of NPK fertilizer and poultry manure at 50:50 ratio in conjunction with variety NHAE47-4, could be adopted for higher pod yield.

The growth and yield of cucumber in response to the effect of poultry manure and inorganic fertilizer (NPK 20:10:10) was evaluated at the Teaching and Research farm of Kogi State University Anyigba, Nigeria during the 2021 raining season. Treatment consisted of poultry manure which was applied at 0, 7.5 and 15t/ha and inorganic fertilizer (NPK 20:10:10), applied at the rate of 0, 0.2, 0.4 and 0.6t/ha respectively. The experiment was laid in a Randomized Complete Block Design (RCBD) with three replicates following all agronomic practices as recommended. Combined rates of poultry manure at 15t/ha and 0.6t/ha of fertilizer were found to significantly increased (P≤0.05) growth characters such as number of leaves, vine length at 4, 6 and 8WAS. Longest vines of 602.75cm and 213.75leaves was obtained with combined application of 15t/ha PM + 0.6t/ha NPK fertilizer at 8WAS respectively. Similarly, Fruit length, Number of fruits, Fruit weight/plant, Fruit yield/ha were significantly influenced (P≤0.05) by the combined application of 15t/ha PM + 0.4t/ha NPK, while the control plots consistently gave the least yield across sampling periods.
