ABSTRACT
Pongamia pinnata is commonly known as Karanja is a moderate sized evergreen tree and bark is smooth, gray and thin. Studying about this particular provenance is valuable in various aspects particularly estimating the carbon sequestration potential and extraction of biodiesel from the seed of this tree to be an input for the climate change mitigation activities taking place in India and in the world at large, since climate change is the worldwide issue.It was observed from the result during the 10th year of plantation (2015) different provenances showed the significant influence on the above ground biomass, Significantly maximum above ground biomass (138 kg ha-1) was recorded in provenance T13 (Nagod road, Satna), whereas minimum (410 kg ha-1) was recorded in T21 (Krishi Vigyan Kendra, Seoni).Different provenances observed significant among themselves for carbon sequestration potential at age of ten year old . Significantly maximum carbon sequestration potential (3.39 tons/ha) was recorded in provenance T13 (Nagod road, Satna), whereas minimum carbon sequestration potential (0.97 tons/ha) was recorded in T21 (KVK, Seoni). Carbon sequestration through above mentioned provenances have potential to play important role in ameliorating global environment problems such as atmospheric accumulation of greenhouse gases (GHGs) and climate change. Therefore plantation of such superior provenance should be implemented and measures should be taken to protected the sink of carbon and mitigate the greenhouse effect through carbon storage.
ABSTRACT
A research experiment was conducted at vegetable research Complex, Maharajpur, Department of Horticulture, College of Agriculture, JNKVV Jabalpur. The experiment was done to study the effect of sulphur and salicylic acid on Yamuna safed -2 variety of Garlic. The growth, yield, and quality of garlic can be influenced by various factors, including nutrient availability and plant growth regulators like salicylic acid. Sulphur is an essential nutrient for plant growth and plays a crucial role in the development of garlic plants. The experiment was conducted in Randomized Block Design with combination of different concentrations of sulphur (0 kg/ha, 30 kg/ha and 45 Kg/ha) and salicylic acid (60 ppm and 120 ppm). Growth parameters like plant height, number of leaves and pseudostem diameter were found maximum in treatment T-9 (sulphur 45kg/ha and SA 120ppm). Yield parameters like average bulb weight (22.27 gm), Polar diameter (4.41 cm) and Equatorial diameter (3.79 cm) average weight of 10 cloves (9.10 gm), Total soluble solids and Pyruvic acid were also maximum in T-9 (Sulphur 45kg/ha and SA 120 ppm) (42.30 oBrix and 66.09 µmol/gm respectively). From the above findings it can be concluded that for garlic plant the best doses for salicylic acid and sulphur were found to be 120 ppm and 45 kg/ha. Also with graded levels of salicylic acid and sulphur various parameters increased effecttively.
ABSTRACT
A field study was conducted during Rabi season 2022at the Horticultural Research Farm, Mangalayatan University, Jabalpur to study the effect of foliar application of nano urea and urea on growth and yield of onion. The experiment was laid out in RBD with three replications and consisted of 9 treatments viz., T1-100% RDF (100:50:50 kg NPK ha1), T2-75:50:50 kg NPK ha-1 + foliar spray of 0.4% nano urea on 30 and 60 DAT, T350:50:50 kg NPK ha-1 + foliar spray of 0.4% nano urea on 30 and 60 DAT, T4-75:50:50 kg NPK ha-1 + foliar spray of 0.4% nano urea on 30 DAT, T5-50:50:50 kg NPK ha-1 + foliar spray of 0.4% nano urea on 30 DAT, T6-75:50:50 kg NPK ha-1 + foliar spray of 0.5% urea on 30 and 60 DAT, T7-50:50:50 kg NPK ha-1 + foliar spray of 0.5% urea on 30 and 60 DAT, T8-75:50:50 kg NPK ha-1 + foliar spray of 1% urea on 30 and 60 DAT, and T9-50:50:50 kg NPK ha-1 + foliar spray of 1% urea on 30 and 60 DAT. Each treatment showed their significant effects on the recorded growth and yield parameters. Among all the treatments, treatment T2 with 25% reduced nitrogen application plus foliar spray of 0.4% nano urea on 30 and 60 DAT recorded maximum plant height on 90 DAT (57.82 cm),number of leaves (9.13), equatorial diameter (5.51 cm), polar diameter (5.17), average bulb weight (69.56 g), bulb yield (336.40 kg) than other treatments.
