Optimization of organic manure application for blueberry vegetative growth and photosynthesis

The use of manures and irrigation systems are essential ways to improve the fertility of coastline poor soils in Côte d’Ivoire and to optimize crop yields at any time of the year. The present study aims to identify the best manures and irrigation systems suitable for the vegetative growth of eggplant on the tertiary poor soils of the coast in Côte d'Ivoire. For this purpose, combinations of fertilizer (urea and organic manure from chicken droppings) and irrigation techniques (manual watering and drip irrigation system) were tested in Fisher block design. So, vegetative growth variables of Eggplant, Aub 21N / 06, grown on tertiary soil at the Marc Delorme research station of the Centre National de Recherche Agronomique (CNRA) in Southern Côte d'Ivoire were evaluated. The results showed that the growth dynamics of collar circumference, height and leaf production of eggplant irrigated by drip system and fertilized with organic manure from chicken droppings was significantly higher. The eggplants that received a treatment composed by organic or chemical manure without irrigation and those without manure and irrigation expressed lower vegetative growth. The organic manure from chicken droppings associated with the drip irrigation regime had a significant beneficial effect on the average growth rates of the collar circumference (0.0035 cm.day-1), height (0.5669 cm.day-1) and leaf production (3.12 leaves.day-1) of eggplant. It appears that organic manure from chicken droppings associated with drip irrigation regime is an agricultural innovation to disseminate to market gardeners to cultivate the eggplant on littoral tertiary soil.

Phosphate Solubilizing

Farmyard manure and biofertilizer is able to substitute chemical fertilizers in improving the plants growth and production. The manure acts as the energy source for soil microbes, while biofertilizer with phosphate solubilizing microbes (PSM) can increase phosphate (P) availability for plants. The research aimed to investigate the effect of farmyard manure added with PSM on growth and yield of 5 Robusta coffee clones, conducted at Pakuwon Experimental Station, Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, from January 2014 to June 2017. A split plot design was used with 3 replications. The main plot factors were 5 Robusta coffee clones (BP 308, SA 237, BP 42, BP 358, and BGN 371), whereas the subplot factors were types of fertilizers (chicken, sheep, and cow manure added with PMS), and NPK fertilizers as control. Variables observed were components of vegetative growth, percentage of flowering plants, and weight of fresh berries. The results showed that 5 Robusta coffee clones used exhibited similar responses to the PMS-added farmyard manure application. Chicken manure added with PMS enhanced P-available and improved vegetative growth of coffee plants better than other farmyard manure, similar with the effect of NPK fertilizers. Up to 4 years old plants, the PM-added farmyard manure application did not affect the weight of fresh berries.
