In this study, Lythrum salicaria plant was tested in hydroponic culture to demonstrate its zinc accumulating capacity and tolerance to different zinc levels. Lythrum salicaria seedlings were grown in 10% Hoagland solution containing 0, 5, 10, 20, 30, 40, 50, 75, and 100 mg/L zinc, and 30 mg/L zinc with different pH levels (5, 6, and 7). Following this, the seedlings were harvested after 1st, 2nd, 4th and 7th days. Zinc caused significant decreases in the relative values of the mean root-shoot length and fresh weight of the plant (92 to 75%; 100 to 92%; 64.2 to 41.

Blue pine (Pinus wallichiana) plantations in Kashmir forests have been noticed to be affected by blight diseases showing typical symptoms of shoot blight, die-back and curling of terminal shoots. Plants grown in nutritionally poor soils are more susceptible to diseases. The type of major nutrient supplementation plays a major role in predisposition of plant to the infection by needle blight pathogens. Three fungi were isolated from the infected needles of Blue pine bearing fructification.

Field experiments were conducted in D-2 block of Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Distt. Udham Singh Nagar (Uttarakhand) during 2017-18 and 2018-19. The objectives of the investigation were to study effect of tillage systems and residue loads on the initial establishment, growth attributes and productivity of wheat. The soil of the experimental plot was clay loam high in organic carbon (0.80%), medium in available nitrogen (246.3 kg/ha), high in available phosphorus (22.7 kg/ha) and medium in available potassium (180.

The field experiments were conducted at Nematology field, ICR Farm, AAU., Jorhat during 2016 and 2017 to know the efficacy of bioagent, P. fluorescens and biofertilizer, Azotobacter sp. for that P. fluorescens and Azotobacter sp. were enriched in the substrates like farmyard manure, vermicompost and enriched compost. After enrichment of P. fluorescens and Azotobacter sp. were applied singly and in combination at the rate of 1% per hectare (ha). These treatments were compared with untreated control. It was recorded that the combined application of P. fluorescens and Azotobacter sp.

The investigation was conducted at Department of Horticulture College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra during the year 2015-16 and 2016-17 to assess the effect of foliar nutrition on post monsoon vegetative flush and flowering in mango cv. Alphonso. The experiment was laid out in Randomized Block Design with three replications and seven treatments viz; Urea1% , Potassium nitrate - 1%, Orthophosphoric acid- 0.1%, Urea-3% , Potassium nitrate - 3%, Orthophosphoric acid- 0.2% and control (No spray). Two sprays were taken in each treatment.

This paper discusses about the biochemical and morphological changes in Eucalyptus sp clones to elevated CO2 conditions in AOTC (Automated Open Top Chambers). In this study, three months old clones of Eucalyptus sp were exposed to elevated CO2 levels in open top chambers at 900 ppm and 600 ppm for a period of four months. In Eucalyptus sp clones, the highest values of chlorophyll was recorded by the clone I (39.48) and the lowest values of chlorophyll (26.70) is recorded in clone V in ambient conditions for Eucalyptus sp after four months. The clonal mean was high (36.

The dehesa is an ancient agrosilvopastoral system created by farmers to raise livestock, mainly on private lands. This system is highly appreciated by society and enjoys legal protection of the authorities because it is rich in biodiversity, a home to critically endangered species (Iberian lynx, imperial eagle and black vulture); a significant carbon sink; ethnologically and anthropologically valuable (culture and traditions); and is known for its scenic value.
