Land degradation is a global phenomenon. Endless desires of man have put enormous pressure on this valuable natural resource. India is reported to have 175 million ha of land under various stages of degradation. Deforestation and improper land management are the main reasons. The great diversity in topographic conditions is responsible for an annual loss of about 6000 million tonnes of top fertile soil. Any improvement programme concerning soil health can not be achieved unless it incorporates soil and water conservation. Studies were conducted to assess improvement in soil properties due to adoption of soil-water conservation method (staggered trenching) on hilly slope in Jabalpur District of Madhya Pradesh , India. At site I Tectona grandis was planted at 2 m × 2 m spacing and in between rows staggered trenches of 3 m × 0.5 m × 0.5 m were dug. Observations recorded after 4.5 years of planting showed considerable improvement in soil properties , more so on the lower slope in respect of organic carbon , available nutrients (N , P and K) etc. Soil loss has also been reduced to a considerable extent. At site II Albizia procera and Albizia lebbek were planted and soil-water conservation measures were adopted in a similar way as at site I. This site also showed remarkable degree of improvement in soil properties at 4.5 years of age. Originally both sites were having highly eroded surface and the soil depth was as less as 15 to 20 cm underlain by hard rock and morrum. The soils were quite deficient in nutrients and were having low water building capacity. The growth of planted species was significantly higher than control.- Butea monosperma:The Palash-A Versatile Tree Full of Virtues

Butea monosperma (Fabaceae) commonly called Palash and "Flame of the forest" is a tree growing in abundance in most part of India, Berma, Srilanka and Pakistan is valued in Indian pensula for its religious general and therapeutic applications. It is well known for its folk loric and traditional curative values. The tree possesses aphrodisiac, anti implantation, antistress, antibacterial, antidiarrhoel, anthelmintic, anti inflammatory, antihepatotoxic and wound healing activities which may be due an array of phytoconstituents present in nearly all its plant morphology.Keywords

Valsartan, an angiotensin receptor blocker, has been widely used for the treatment of hypertension, heart failure and heart attacks. Two rapid, sensitive and reliable UV-Spectrophotometric (Method A) and first order derivative (Method B) have been developed for estimation of valsartan in bulk and tablet. In methanol, the λmax of valsartan was found to be 249 nm. The same spectra was derivatised into first order derivative, at Δλ=2; the amplitude of the through was measured at 268 nm. The linear concentration ranges were 5-50 μg/ml for both the methods. The results of analysis were validated statistically. The Relative standard deviations for all the parameters were found to be less then the 5%. The method herein described can be employed for quality control and routine analysis of drugs in pharmaceutical formulations.Keywords

The MACE telescope has recently been commissioned at Hanle, Ladakh, India. It had its first light in April 2021 with a successful detection of very high energy gamma-ray photons from the standard candle Crab Nebula. Equipped with a large light collector of 21 m diameter and situated at an altitude of ~4.3 km amsl, the MACE telescope is expected to explore the mysteries of the non-thermal Universe in the energy range above 20 GeV with very high sensitivity. It can also play an important role in carrying out multi-messenger astronomy in India.Keywords
