Harvesting biomass

Harvesting microalgae by centrifugation and filtration is very costly, affecting technical and economical feasibility of downstream processing of algal biomas to bioproducts. Flocculation is a potential technique for recovery of algae biomass. Particularly, flocculation using magnetic nanoparticles offers high separation efficiency due to their high surface area and magnetic properties. I

In ebook "Harvesting the biosphere: What we have taken from nature" Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests-from prehistoric man's hunting of megafauna to modern crop production and all uses of harvested biomass, including energy, food, and raw materials.

Microalgal harvesting has still been a challenge to investigators who take their investiment into microalgal production. The cost for microalgal downstream processing is as high as 20% of the total production of biodiesel. Among hundreds of curent methods of biomass harvesting, autoflocculation and bacteria-based aggregation are still being researched and applied in large-scale producuion.

A field experiment was conducted at the Livestock Farm, JNKVV, Jabalpur during Rabi season 2017 and 2018 to check the bio-efficacy of pendimethalin (38.7% CS) as PPI against complex weed flora in chickpea. Species wise weed data were recorded in weedy check plots revealed that Medicago denticullate (62.08%) and Cichorium intybus (32.85%) were most dominant. However, other monocot weeds like Cyperus rotundus (3.12%), Cynodon dactylon (1.95%) were also present in less numbers in chickpea.

M. dubia growth and yield performance was evaluated using Randomized Block Design with 10 treatments. There was significant variation in tree height (m), girth at breast height (GBH) (cm), and standing volume (m3 /tree or /ha) and biomass (kg/tree or t/ha), at SSG intercropping (July, 2019) and final SSG forage harvest (November, 2019), among the silvi-pasture (T1 to T5) and sole plantation (T6 to T10) systems.

Paddy is major crop of India. The grain to straw ratio in paddy crop is 1:1.25 and paddy crop generates huge amount of biomass and it alone contributes 34 % to total biomass production in India. Mostly combines are used for harvesting the paddy crop. The end use of paddy straw is not yet wide spread either on farm or in industrial sector. Thus straw management in combine harvested paddy fields is a major problem in paddy fields. To overcome this problem, it was proposed that paddy straw is first chopped and then incorporated in soil with minimum tillage efforts.

Transgressive segregation is a very important phenomena where the segregating individual will possesses the value for a character which is exceeding the better parent. In the present study transgressive segregants were studied in four crosses for SCMR(SPAD Chlorophyll meter reading), SLA (specific leaf area), total biomass per plant, shoot weight per plant, root weight per plant, shelling out-turn per plant, harvest index per plant, pod yield per plant and kernel yield per plant. All the characters under study showed transgressive segregation in all the four crosses.

The aim of this study was the calibration and validation of DSSAT model (v4.5) for late sown wheat in western zone of Haryana. The DSSAT model was calibrated with the field experimental data of rabi 2010-11 having 3 levels of irrigation (one irrigation at crown root initiation [CRI], two irrigations at CRI and heading and four irrigations at CRI, late tillering, heading and milking) and 5 nitrogen levels (0, 50, 100, 150 and 200 kg N/ha) and validated with data of experiment rabi 2011-12 conducted at Hisar (29°10ˈ N and 75°46ˈ E).

India is the largest cotton producing country, covers an area of approximately 36 % area representing about 11.3 million hectares under cotton. It also consumes considerable amount of herbicides and pesticides which are biologically active compounds which may lead to the significant changes in the soil microorganisms. Hence, in this study the herbicides viz., pyrithiobac, pendimethalin and pyrithiobac + quizalofop are sprayed as pre-emergence herbicides and the soil samples were collected at squaring, flowering, boll formation and at harvesting stage.

Chlorella vulgaris was cultured in chemostat mode and harvested on a semi-continuous basic with 50% of broth volume every two days, giving the highest biomass yield. The flocculation efficiency of microalgae using chitosan depended on dose use, quality of chitosan such as degree of deacetylation (DD) and solubility. The flocculation efficiency was 99% after 30 minute, and 95% after 10 minute for DD of 87% and 89.8%, respectively.

Rice straw being rich in cellulose and plentily available, it can serve as the chief renewable biomass resource for biofuel production. Several protocols are now available for efficient recovery of ethanol from cellulosic substrates of rice straw. Rice varieties showing high lignocellulosic straw biomass inherently reveal low harvest index and consequently low grain yield potential.
