Seaweed Extract and Indoleacetic Acid Foliar Application in Relation to The Growth Performance of Sweet Pepper Grown Under Net House Conditions

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.

Silicon is one of the most significant elements in plants under abiotic stress, so we investigated the role of silicon in alleviation of the detrimental effects of salinity at two concentrations (1500 and 3000 ppm sodium chloride) in sweet pepper plants in two seasons (2018 and 2019). Our results indicated that relative water content, concentrations of chlorophyll a and b, nitrogen, phosphorus and potassium contents, number of fruits plant−1, fruit fresh weight plant−1 (g) and fruit yield (ton hectare−1) significantly decreased in salt-stressed sweet pepper plants as compared to control plants. In addition, electrolyte leakage, proline, lipid peroxidation, superoxide (O2−) and hydrogen peroxide (H2O2) levels, soluble sugars, sucrose, and starch content as well as sodium content significantly increased under salinity conditions. Conversely, foliar application of silicon led to improvements in concentrations of chlorophyll a and b and mineral nutrients, water status, and fruit yield of sweet pepper plants. Furthermore, lipid peroxidation, electrolyte leakage, levels of superoxide, and hydrogen peroxide were decreased with silicon treatments.

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.

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.
