Subject: Biomass production of high density Leucaena leucocephala plantation
Keywords: Biomass, Coppice shoots, Growth parameters, High density plantation, Nutrients.
Abstract: High density subabul (Leucaena leucocephala) plantation are being raised in Punjab for biomass based electricity generation. An experiment was conducted at PAU Ludhiana to standardize the nutrient requirement of high density (1 x 1 m) plantation of subabul for its high biomass production. Six combinations of nitrogen, Phosphorus and potassium viz.0:0:0 (Control) 0:0:0 (control), 20:20:10, 40:40:20, 60:60:30, 80:80:40 and 100:100:50 kg/ha N: P2O5:K2O were tested. The data on growth parameters (collar diameter, height and branch numbers) fresh and dry biomass of stems, branches, leaves and total biomass were recorded one year after planting and subsequently that of six month old coppice shoots. Collar diameter and plant height after one year growth were minimum (1.92 cm and 2.51 m, respectively) without application of nutrients while maximum (2.63 cm and 3.68 m, respectively.) with the application of N: P2O5:K2O @ 40:40:20 kg/ha (14.98 and 22.36 t/ha, respectively) than other nutrient levels. The stems, branches, leaves and total dry biomass after one year growth was the lowest (2.92, 0.86, 1.36 and 5.15 t/ha, respectively) without nutrient application and significantly highest with the application of N: P2O5:K2o@ 40:40:20 kg/ha (3.75, 0.95, 1.79 and 6.49 t/ha, respectively).Fresh and dry biomass of six-month-old coppice shoots was higher than the biomass of previous one year. Thus, it is advisable to apply nutrients @40:40:20 kg/ha N: P2O5:K2O every year to obtain maximum production of high density subabul plantation.

Abstract: Various State Governments monitor the plantations raised by them periodically and collect data regarding location, extent, survival percentage, average height, girth etc. In this paper, efforts were made to prioritize these parameters and integrate them to get an overall grading of plantation so that various plantations within schemes and between schemes can be compared and ranked properly. In future this grading can be related with sustainability so that management can take remedial measures in plantation with low grades.

Subject: Elevated CO2 enhanced growth and physiological process of Populus deltoids
Keywords: Populus deltoids, Physiological response, Stem diameter, Open top chamber
Abstract: Accumulation of CO2 , in the atmosphere considerably affect plants and trees of the terrestrial ecosystem. Under elevated CO2 plants may alter growth and physiology for adaptation to survive. The aim of this study was to investigate the physiology for adaptation to survive. The aim of this study was to investigate the physiological and growth response of Populus deltoids grown under 600 µmol mol-1 of CO2 concentration in open top chamber (OTC).One-month-old homogenous plants were transferred in OTC for 180 days exposure of treatment and observed that as compared to control (~400 µmol mol-1), stem diameter, photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO2 concentration, intrinsic carboxylation efficiency and Ci/Ca were increased significantly. Intrinsic water use efficiency, instantaneous WUE, and Ci/gs were decreased significantly compared to control. The results indicated that P.deltoids plants can respond to elevated CO2 in terms of growth by the mechanism of photosynthesis and increased physiological processes. Plants maintain stronger stress tolerance mechanism via improvements in the synthesis of photosynthate and water retention capacity. Such behaviour may facilitate plant adaptation to deal with climatic change and global warming. Tree productivity, vegetation, and ecosystem health may also be improved.

Subject: Bamboo Based agroforestry for sustainable utilization in Land under shifting cultivation of Assam
Keywords: Jhum, intercropping, Agroforestry, Bambusa balcooa, Agricultural crop
Abstract: A field study was conducted intercropping agricultural crop with Bambusa balcooa for four consecutive years in Rongbonghat, Karbi Anglong district, Assam. Culm cutting of B.balcooa was planted in three different spacing trial (3 x 3m, 4x 4 m and 5 X5m) intercropped with maize (Zea mays L.) and colocasia (Colocasia mannii Hook f.) as per local demand of the people. Growth parameter of bamboo in solo plantation as well as intercropped with agricultural crops recorded remarkably more in 5 x 5 spacing during 4th year of experimentation. Highest numbers of newly emerged bamboo shoot and maize cob were recorded in 5 x 5 m spacing. Yield of maize ( 22.89 qt/h) and colocasia ( 3.54 qt/h) was recorded less in the initial of year cultivation at 3 x 3m spacing, gradually increased in yield was observed subsequent year ( maize-33.8 qt/h and colocasia 5.27 qt/h) up to third year cultivation at 5x 5 spacing. Productivity of crops gradually declined after third year of cultivation due to profuse growth of bamboo and dense canopy cover which may causes the competition of nutrients and light between two growing crops. Increments of soil nutrients also plays key role for the production of crop yield and growth parameter of bamboo. At the initial stage, least value of Ph, organic carbon and NPK was noticed in soil under intercropped plot, while it increase in successive year due to decomposition of maize straw, bamboo leaf and other crop biomass. Addition of root and shoot biomass also lowered acidity from initial level and enhance the soil fertility. Biomass retained the moisture content and creates a favourable environment for development of plant growth up to third year of cultivation and gradually declined due to prolific growth of bamboo. The present research work has been carried out to develop a bamboo based agro forestry to enhance the sustainable productivity of jhum land.

Keywords: Forest policy, Forest cover, Trees outside Forests (ToF), Farm Forestry, Farm gate price, Agro forestry
Abstract: National Forest Policy 1988 intends to reduce the pressure on natural forests for fuel wood, fodder and industrial raw material and lays emphasis on growing trees outside forests. In this article, Authors have presented an analysis on the growth of farm forestry and agroforestry, which are major components of the ‘Tree growth outside forests’, In terms of spread, intensity, profitability and sustainability. Creation of a wood resource base of more than a million hectare outside forests in the country has benefitted the farmers and industry, and has reduced considerable pressure on forests. Authors argue that enabling policy and regulatory framework, improved tree productivity, and consistent farm gate price would help in realizing the full potential of farm forestry/agroforestry in India.

Abstract: India is committed to increasing the share of renewable energy in its electricity generation mix. With the rapidly declining cost of power from large-scale wind and solar projects, the renewables’ share has risen from around 5 per cent in 214-15 to over 9 per cent in 2018-19. By 2021-22, over 21 per cent of the power produced in India would come from renewable. However, the renewable energy sources (barring geothermal) are inherently intermittent and variable, changing over a wide range of timescales. Reliable and cost-effective integration of Variable Renewable Energy (VRE) with the electricity grid will be essential to achieve the ambitious goals of deployment.

Abstract: With global issues such as climate change and other energy-related problems, the need of the hour is an efficient fuel with zero carbon footprints and this path can be achieved by using hydrogen and other environment-friendly options such as biofuels. Biofuels can be produced from different organic wastes that can be harnessed easily. I can also be used in existing combustion with methane from natural gas. Hydrogen, with the highest energy density (143 kJ/g), is a clean and environment-friendly fuel. Biohydrogen production using renewable resources (solid wastes/wastewaters) is a promising economical and sustainable energy source as compared to photobiological processes mainly due to very high hydrogen production rate and being less energy intensive. The organic wastes are responsible for environmental pollution to a great extent.

Abstract: Undeniably, financial volatility and climate change are considered to be the prime catalysts of alteration in the global ecology that could profoundly impact business and society. In the last decade, it is universally gathered that the corporate sourcing of renewable has the potential to churn substantial investments into renewable energy. With the right framework in place, it could enable not just the acceleration of the energy transitions but also shift the world closer to achieving the Paris Agreements objective. The year 2018 drew to a close with a hotly-contested ‘Katowice Climate Package’ finalized at COP24, establishing a set of guidelines to make the Paris Agreement operational by 2020.

Abstract: Existing market challenges for the stakeholders lead to the slow uptake of rooftop sola in the residential sector. For the consumers, high upfront cost, difficulty in accessing finance, lack of awareness, and lack of access to suitable roof spaces are some of the major challenges. The solar developers and financiers also find it unfavourable to serve the residential sector is compared to the industrial, commercial, and institutional sectors. This is due to the small and distributed nature of residential solar systems. For the developers, this leads to higher business development and logistics costs.

Abstract: Being in Agarian economy, India supports nearly 50% of its population through agricultural activities. The major hindrance in the agricultural sector is erratic power supply and too much reliance on polluting diesel-powered pumps. Approximately, around 30 million agricultural pumps are installed in India. Of these, 10 million pumps are runs on diesel fuel and the rest 20 million agricultural pumps in the country are operated through grid supply. The agricultural sector consumes around 20% of total Indias installed power. Thus, fluctuating diesel prices, unreliable power supply, dependency on unpredictable monsoon rains, comprise an additional burden on farmers.

Abstract: The genus Brassica L. belongs to family Brassicaceae (Cruciferae) under the tribe Brassicae (Rakow 2004).A good number of species (3000 to 4130) and genera ( 365 to 419) has been reported by different scientists in family Brassicaceae (Warwick et al., 2006) .It includes crop Brassicas which are important edible crop species used as vegetable, oilseed and condiment crops globally (Singh et al., 2017).In India , rapeseed-mustard stands second after soybean in terms of area (24%) and production (25%) among oilseed crops. B.Jincea (Indian mustard L) is holding sizable contribution in terms of area and production of oilseeds and edible oils (Jat et al., 2019).In India , a gradual increase in the production of oilseed brassica was recorded from a mere 0.76 million tonnes (1950-1951) to 9.34 million tonnes (2018-19) (Agriculture Statistics at a Glance, 2019).Because of increasing population, changing food habits and improved purchasing power, the demand of vegetable oils is likely to grow up to 82-102 mt of oilseeds by 2030 from the present level of 33.50 mt during 2019-20.Further , the projected demand for this rapeseed –mustard would be around 16.4-20.5 mt by 2030.Realizing the exploitable yield reservoir by narrowing yield losses due to biotic (disease and insect pest) and abiotic stresses ( drought , heat , frost) is one of the strategy to achieve this growing demand (Chauhan et al., 2020).
