The effect of foliar application of commercial seaweed extract on potato growth was studied in long-day conditions (60° 10' N 25°00' E) characterized by a cool and short growing season. The results showed that neither the doses, 0, 5, 10, 20 l/ha nor the spraying 24, 45, 58 days after the emergence had any remarkable influence on potato growth and yield if the other preconditions of production are in order. Only small, although insignificant benefit could be obtained with application done three weeks after emergence, clearly before tuber initiation.

The present study investigated the effects of dietary supplementation of a seaweed extract (SWE) to sows and weaned pigs on post-weaning growth performance, intestinal morphology, intestinal microflora, volatile fatty acid concentrations and immune status of pigs at days 11 and 117 post-weaning. Gestating sows (n20) were supplemented with a SWE (0v.10·0 g/d) from day 107 of gestation until weaning (day 26). At weaning, pigs (four pigs per sow) were divided into two groups based on sow diet during lactation and supplemented with a SWE (0v.2·8 g/kg diet), resulting in four treatment groups: (1) BB (basal sows–basal pigs); (2) BS (basal sows–treated pigs); (3) SB (treated sows–basal pigs); (4) SS (treated sows–treated pigs). Pigs weaned from SWE-supplemented sows had a higher average daily gain (ADG) between days 0 and 21 (P < 0·05) post-weaning compared with pigs weaned from non-SWE-supplemented sows. Pigs offered post-weaning diets (PW) containing SWE had decreased colonicEscherichia colipopulations on day 11 (P < 0·01) and decreased colonic Enterobacteriaceae numbers on day 117 (P < 0·05). Pigs offered PW containing SWE had a greater mRNA abundance ofMUC2in the colon at day 11 post-weaning (P < 0·05) compared with pigs offered unsupplemented diets. In conclusion, these results demonstrate that SWE supplementation post-weaning provides a dietary means to improve gut health and to enhance growth performance in starter pigs. Dietary SWE supplementation increased ADG during the grower–finisher (GF) phases. However, there was no growth response to SWE inclusion in GF diets when pigs were weaned from SWE-supplemented sows.

The Seaweed (Padina antrillarum) abundantly found in the coastal region of Eastern Sri Lanka. Seaweed contains a wide range of nutrients and hormones for plant growth. An experiment was conducted at the Crop Farm, Eastern University, Sri Lanka to assess the effects of seaweed (Padina antrillarum) extract on the flowering of roses var. ‘Local’ from July to September 2020. Four treatments were used in this experiment viz. 10% (T1), 20% (T2), and 30% (T3) seaweed extracts with control treatment (T4). Treatments were applied at once-a-week interval. The experimental design was a completely randomized design with three replications. All other management practices were followed uniformly. Measurements were done at once a month. Collected data were analyzed. The higher performances in measured parameters (plant height, leaf area, plant biomass, number of flowers per plant) were observed in T2. It showed that once a week application of 20% seaweed liquid extract had the potential to increase growth and flower production in roses. It might be due to the presence of nutrients and the growth hormones in seaweed extract and optimum concentration of seaweed extract received by plants at T2. In T1 and T3, plants received sub-optimum and higher concentration respectively. It could be the reason for the lowest performances in these treatments. From this experiment, it could be concluded that once a week application of 20% seaweed liquid extract of Padina antrillarum is suitable to increase flowering in roses of treatment tested.

Apple Quality

Nutritional unbalances, such as calcium deficiency at the fruit level, are generally the causative agent of post-harvest disorders in apples. Foliar application of Ca as calcium chloride is the current solution to increase Ca concentration in apples, even though the effectiveness of this approach is often not satisfactory. In this research, we tested the efficacy of a combined application of Ca with selected biostimulants to improve apple quality and to reduce the incidence of storage disorders. The experiment was conducted in two “Jonathan” apple orchards that differed in management systems and characteristics. Tree canopies were sprayed with calcium chloride alone and in combination with a commercial product containing zinc and silicon or a seaweed extract. The seaweed extract increased apple quality by boosting the reddish coloration (+32% of color index) and by enhancing final anthocyanin concentration of fruit skin. Both biostimulants significantly reduced (by 20%) the incidence of the physiological disorder, known as “Jonathan spot”, after 160 days of storage. Increased concentration of nutrients (Ca, Zn, and Mn) in the skin of apples after biostimulant applications, together with changes of the phenolic profile during the storage, are discussed as the possible causes of the reduced fruit susceptibility to post-harvest disorders.

Abstract This study was conducted in a certified citrus production nursery in Karbala province, Al-Hindiya district for the season 2020, on lime seedlings (Citrus aurantifolia) rootstock at the age of 6 months, It was sprayed with the nutrient solution Biumin 221 at concentrations (0, 1.5, 2, 2.5 m.L-1) and Basfoliar Kelp seaweed extracts at concentrations (0, 1.5, 3, 4.5) ml L-. The results showed that spraying the seedlings with single and combined study treatments led to a significant increase in all the vegetative and nutrition traits of lime seedlings. The treatment (2.5 g.L-1 nutrient solution + 4.5 ml.L-1 seaweed extract) achieved the highest averages in most of the traits. While the interaction treatment between the concentration (2.5 g.L-1 of the nutrient solution and concentration of 3 ml.L-1 of seaweed extract was excelled in the traits of leaf content of total carbohydrates, the percentage of nitrogen, iron, and zinc.
