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.
Variability of Fusarium Solani Isolates Causing Wilt Disease of Clusterbean
The clusterbean [Cyamopsis tetragonoloba (L.) Taub.] is belong to the Leguminosae (Fabaceae) family. Wilt disease of clusterbean is a seed and soil borne in nature and this disease incited by Fusarium solani. The pathogen creates wilt in seedlings until they reach maturity. Infected plants show girdling at the collar region later in their growth stage resulting in wilting of the host plant. A total of eight isolates of F. solani were established from the surveyed districts of Rajasthan. Isolates were transferred separately on PDA in Petri dishes to study in detail for their discernible characters on the basis of cultural and morphological characters such as the colony diameter, colour and growth patterns. For pathogenic variability, the susceptible variety (RGC-1055) was inoculated with different isolates separately. Cultural and morphological variability were recorded in each isolate and FsJd-1 isolate, collected from Mandor tehsil in Jodhpur district, showed maximum variability in colony diameter, colony characters like pinkish white colony with fluffy growth, in maximum number, length and septa of macro and micro conidia. Among eight isolates, FsJd-1 isolate was found to be most virulent as it produced maximum disease (46.15 %) and categorized as highly virulent.
RESPONSE OF SORGHUM TO LIQUID INOCULANTS OF AZOSPIRILLUM BRASILENSE AND PHOSPHATE SOLUBILIZING BACTERIA
A field experiment entitled “EFFECT OF LIQUID INOCULANTS OF AZOSPIRILLUM BRASILENSE AND PHOSPHATE SOLUBILIZING BACTERIA ON GROWTH AND YIELD OF SORGHUM” was undertaken during the kharif season of 2018 on clay loam soil of Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). Experiment was laid out in the factorial randomized block design in three replications. There were twelve treatment combinations consisting of three different levels of RDF viz., F1 - 50% RDF, F2 -75% RDF, F3 -100% RDF (80:40:40 kg/ha of N:P2O5:K2O) and four seed treatments viz., S1 -Control (without seed treatment and only application of fertilizer), S2 - seed treatment with Azospirillum brasilense and phosphate solubilizing bacteria @ 25 g each/kg seed, S3 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 2 ml each/kg seed and S4 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 4 ml each/kg seed. Among different levels of RDF, 100% RDF recorded significantly higher plant height (203.68 cm), total dry matter accumulation (145.50 g/plant), grain yield (43.06 q/ha), fodder yield (92.75 q/ha), protein content (9.61%), protein yield (414.26 kg/ha). However, application of 50% RDF recorded significantly higher rhizospheric effect (cfu/g of soil) of both Azospirillum and PSB at seedling, flowering and grain filling stages. Seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 4 ml each/kg seed recorded significantly higher plant height (198.93 cm), total dry matter accumulation (140.79 g/plant), grain yield (43.27 q/ha), fodder yield (93.78 q/ha), protein content (9.60%), protein yield (415.53 kg/ha) and rhizospheric effect (cfu/g of soil) of both Azospirillum and PSB at seedling, flowering and grain filling stages over other seed treatments.
Germplasm Evaluation of Grain Amaranthus
A study to assess the variation among 125 grain amaranth accessions using six morphological characters was conducted. Based on per se performance, the promising genotypes of grain amaranth viz.,KBGA10, KBGA11, Durga, VLC 44, SKGPA 63, IC 32186, IC35642, SKGPA65, SKGPA 64, Durga, SKGPA 81, BGA 2, VLC 44 and KBGA 10 were found superior over the checks under comparison (suvarna and annapoorna) for yield and yield contributing traits. Multivariate analysis of phenotypic characters showed the first three principal components contributed 72.74% of observed variability amongst the 125 lines with the eigenvalue >1 and PC1 accounted for 35.84% of the total morphological variation for the traits. Seed volume weight had negative values for the three components (PC 3, 4 and 6) but contributes to the Vth component with highest positive value (0.724).The results will help researchers and breeders to understand, utilize, conserve, and manage the collection for more efficient contribution to amaranth research and cultivation.
