Impact of Drying Technology on the Aloe Vera Gel (Aloe vera barbadensis)
The experiment was carried out at Department of Renewable Energy Engineering, College of Technology and Engineering, Maharana Pratap University of Agriculture and Technology, Udaipur to study drying of aloe vera gel (Aloe vera barbadensis miller) in solar cabinet dryer. In the present investigation, aloe vera dried in solar cabinet dryer and compared with open sun drying method. Results showed that moisture content, average drying rate in aloe vera gel as 98.45 per cent (wb) to 8.82 per cent (wb) and 1.47, 1.34 and 1.19 g/100g dm/ h to 3.96, 2.7 and 2 g/100g dm/ h in solar cabinet dryer and in open sun, respectively. The moisture diffusivity varied in the range of 1.59×109m²/s to 1.54×109 m2/s in open sun drying and 1.88×109 m2/s to 2.56×109 m2/s in solar cabinet drying of aloe vera samples. Among the twelve thin layer drying model, best-ranked model applicable to the variation of moisture ratio with drying time of aloe vera samples in open sun drying were two-term model whereas in cabinet drying was diffusion approach model.
Effect of Storage Periods and Seed Treatment on Seed Quality of Sorghum (Sorghum bicolor [L.] Moench) Genotypes
Sorghum is the forth important crop among the world’s leading cereals. Millions of people in Asia and Africa depend on sorghum as the staple food. Seeds have to be stored, of course, because there is usually a period of time between harvest and planting. Good seed physical quality, germination and vigor is expected to happen with good storage. This study was undertaken to assess storage potential of various sorghum genotypes stored under ambient condition. Seeds of sorghum varieties viz., CO30, CO32, K12 and Paiyur 2, pre-released cultures viz., TNS661, TNS663, TNS676 and TNS680 and land races viz., Vaiyappamalai local, Thenkasi local, Edapadi local and Chithalathur were treated with Carbendazim@ 2g/kg of seed, packed in cloth bag, kept in storage and assessed at bimonthly intervals. During storage, a reduction in vigour and viability was observed both in control and treated seeds in all the genotypes, but reduction is lower in treated seeds. Viability percent was maintained above to the Indian Minimum Seed Certification Standards (IMSCS) (75 %) upto 8 months of storage and in some of the genotypes, it was started to decline below to the IMSCS from 10 months after storage. Among the genotypes, Edapadi local maintained higher germination of 75 and 77% in control and treated seeds, respectively up to 22 months after storage. Hence, from this study it was inferred that the genotypes, edapadi local treated with carbendazim @ 2 g / kg of seed can be stored under ambient condition upto 22 months after storage.
Effect of nutrient management practices on productivity of perennial grasses under high moisture condition
A field experiment was started from Kharif 2012 (establishment year) to 2015 at JNKVV, Jabalpur to evaluate the performance of lowland grasses regarding crop establishment, forage productivity and nutrient management. The treatments consisted of three types of grass, viz., para grass (Brachiaria mutica), humidicola grass (Brachiaria humidicola) and guinea grasses and four nutrient management practices, viz., M1- 100% NPK through inorganic fertilizers; M2- 50% NPK through inorganic fertilizers + FYM @ 5 t/ha; M3- FYM @ 5 t/ha and M4- Farmer practice (without nutrient) laid out in split plot design and replicated three times. The study on the effect of nutrient management on the productivity of perennial grasses under high moisture conditions revealed that the grass Brachiaria mutica grown with M1- 100% NPK (inorganic fertilizer) gave the highest green and dry fodder yield and net monetary returns fb by M2- 50% NPK through inorganic fertilizer + FYM @ 5 t/ha.
Carbon sequestration and oxygen release potential of mono and mixed tree species under High Density Plantations
In modern era, establishing mixed tree species plantations is becoming more popular in an effort to protect the environment. Reports on comparing monoculture tree plantations under High Density Plantation (HDP) is meager. Therefore, an investigation has been carried out to compare the production of total biomass, carbon content, carbon sequestration, and oxygen release between monoculture plantation - HDP 1 (1 species), mixed tree plantations of 7 species (HDP 2) and mixed tree plantations of 14 species (HDP 3). The experimental results indicated that mixed tree plantation with 14 different tree species (HDP 3) has sequestered the highest carbon (4863.03 kg per ha per year) and oxygen release (12968.98 kg per ha per year) while the least was recorded in other two plantations. Hence, the present study strongly recommends that trees grown under mixed plantations with more number of species encompassing diverse tree species plays a superior role in enhancing the environmental quality compared to monoculture plantation.
SCREENING OF BASAL STEM ROT RESISTANT COCONUT HYBRID GENOTYPES IN ENDEMIC AREA OF TAMIL NADU
Coconut hybrid cross combinations of Tall x Tall and Dwarf x Dwarf genotypes were evaluated against basal stem rot (Ganoderma) disease in endemic area of Southern India during 2019-2022. San Raman x Zanzibar, Phillipines Ordinary Tall x West Coast Tall, San Raman x East Coast Tall, Banawali Green Round x Andaman Ordinary Tall, East Cost Tall x Jawa Giant and West Coast Tall x Cochin China were found tolerant to basal stem rot disease. Chowhgat Green Dwarf x Malaysian Green Dwarf and Chowhgat Orange Dwarf x Malaysian Orange Dwarf were found tolerant to basal stem rot.
