“…Medium enrichment with seaweed extract in this study was able to stimulate the filament growth due to the presence of hormones and nutrients in seaweed extract as reported by Prasad et al (2010). K. alvarezii produced nutrients and hormones which have a function in the growth and survival rate of seaweed.…”

The development of micropropagule and embryo of seaweed depend on nutrient and fertilizer used. Seaweed has been reported contain hormone regulators such as auxine, cytokinine, gibbereline, and various minerals applied in stimulating the growth ocra plant and wheat culture. The objectives of this study were to determine the potential of Kappaphycus alvarezii extract and its optimal concentration in accelerating of Kappaphycus alvarezii micropropagule and embryo growth. Micropropagule and embryo produced through callus induction were planted into PES 1/20 liquid medium supplemented with seaweed extract at the concentrations of 0 (control), 25, 50, 75, and 100 μL in 10 mL of medium. The results showed that medium enrichment with 50 μL of seaweed extract had the highest survival rate and growth of thallus. In addition, this concentration was also resulted in a good performance of K. alvarezii thallus with the lighter color. The advantage of this study for seaweed cultivation in Indonesia, among others, seaweed can be used as fertilizer, especially in the maintenance of seaweed seed, so that cultivation can be better develop.

“…It also contains all the trace elements and plant growth hormones required by plant to enhance yield attributes (Latique et al, 2013). Seaweed liquid fertilizer contains micro and macro nutrient and growth promoters (Prasad et al, 2010). Several other mineral and trace elements are also reported to be present in seaweed, which are readily absorbed by plant and they control nutrient deficiency in the plants.…”

Article InfoAn understanding of the dynamics of soil organic carbon (SOC) as affected by farming practices is imperative for maintaining soil productivity. The objective of this study was to assess the effect of tillage systems and inorganic inputs with K sap on the changes in SOC under rice -wheat rotation in western IGP. Results showed that ZT increased soil bulk density in the 0-20 cm soil layer. Adoption of ZT and PRB increased the concentrations of SOC and TC at 0-15 cm depth but decreased the concentrations in deeper soil. The greatest SOC and TC concentrations were observed under ZT at 0-15 cm depth and under PRB at 15-30 cm depth. Adoption of ZT farming enhanced the SOC and TC stocks in the 0-15 cm layer, whereas PRB increased SOC and TC stocks in the 15-30 cm profile. The stratification ratio (SR) of the SOC and TC concentrations was larger under ZT compared with PRB and CT. Thus, the adoption of short-term (5-6 years) ZT practices is beneficial for the enhancement of SOC and TC stocks in the 0-15 cm soil profile, and rotational tillage may be an appropriate farming practice for rice-wheat system. Application of NPK either through inorganic fertilizers or through combination of inorganic fertilizer and organics such as farm yard manure (FYM) with k sap improved the SOC, particulate organic carbon (POC), microbial biomass carbon (MBC) concentration and their sequestration rate. Application of 75% RDF +25% N through FYM with k sap in ricewheat rotation sequestered 0.39, 0.50, 0.51 and 0.62 Mg C ha −1 yr −1 over control, respectively. SOC with response to application of fertilizer partially substituted (25% on N basis) with organics was higher in 15% k sap. The rice water foot print recorded a significant declining trend in RDF plots where as the water foot print trend was stable at RDF+FYM plots and lower value under unfertilized control. The water productivity in RDF fertilized plots and RDF+FYM with k sap showed either an increasing trend or remained stable at all treatments during six years of the experiment.
