TL;DR: In this paper, the impact of salt stress under different salinity level (0,25,50,75,100,125,150 mM NaCl ) on five varieties of wheat viz., HOW-234, HD-2689, RAJ-4101, RAZ-4123, and HD-2045 was conducted.
Abstract: The impact of salt stress under different salinity level (0,25,50,75,100,125,150 mM NaCl ) on five varieties of Wheat viz., HOW-234, HD-2689, RAJ-4101, RAJ-4123, and HD-2045 was conducted. The data showed that different level of salinity significantly affected the growth attributes by reducing root and shoot length for salinity below 125mM. Fresh weight and dry weight of root and shoot were reduced significantly with subsequent treatment. Regarding germination maximum germination was found in variety HD2689 in all the treatments and maximum inhibition was found to be in case of HOW234 variety at 150mM salinity level. Regarding biochemical analysis the sugar, proline content increased with increasing salinity level where as protein content decreased in the physiologically active leaves of different treatments for all the varieties of wheat

TL;DR: The variety B9 recorded a significant higher seed yield along with other yield contributing factors, which was found to be superior to other varieties under old alluvial soil of Burdwan, West Bengal, India, in 2005.
Abstract: Field experiments were conducted with mustard (Brassica campestris cv. B9) consecutively for three years (2005, 2006 and 2007) in the Crop Research and Seed Multiplication Farm of Burdwan University, Burdwan, West Bengal, India. In the first year, varietal screening of mustard under recommended dose of chemical fertilizer (100:50:50) were performed with seven mustard varieties during November 2005 to February 2006. In the second year, two experiments were conducted to study the effects of six different combined doses of chemical fertilizer and biofertilizer and six different levels of growth retardant cycocel. In the third year, six different levels of compost along with the best screened dose of growth retardant (CCC-300 ppm) and the best combined dose of biofertilizer and chemical fertilizer (3/4thchemical fertilizer:1/4th biofertilizer) from the previous year were applied to study the effects on agronomic traits and growth attributes of mustard, and the field data were analyzed statistically. The variety B9 recorded a significant higher seed yield along with other yield contributing factors, which was found to be superior to other varieties under old alluvial soil of Burdwan, West Bengal, India, in 2005. In 2006 and 2007, seed yield was found to be the best for CCC-300 ppm treatment and the best combined dose of biofertilizer and chemical fertilizer was found to be 3/4th chemical fertilizer:1/4th biofertilizer. In 2007, the best yield was given by the treatment of 7.5 t·hm−2 compost along with the best dose of growth retardant cycocel and the best combined dose of biofertilizer and chemical fertilizer.

TL;DR: A study on water quality of eutrophied surface water body of Kalna farm as well as ground water quality was done to investigate the level of pollution and contamination that have occurred in these two sources of fresh water systems Several physicochemical parameters viz, pH, temperature, TDS, turbidity, nitrate nitrogen, phosphate, sodium and potassium content were measured in groundwater samples as mentioned in this paper.
Abstract: A study on water quality of eutrophied surface water body of Kalna farm as well as ground water quality of the area was done to investigate the level of pollution and contamination that have occurred in these two sources of fresh water systems Several physicochemical parameters viz, pH, temperature, TDS, turbidity, nitrate nitrogen, phosphate, sodium and potassium content were measured in groundwater samples For surface water analysis, DO, BOD and COD were mediated to evaluate the pollution load of the surface water bodies surrounding the Kalna farm Results indicate that all the surface water body was nutrient enriched in terms of sodium (1473-2798), potassium (659-1031 mg/L) and phosphate content (052-073 mg/L) in the water whereas ground water contains more salt content than its surface water counterpart Surface water body was found to be alkaline in nature (809868) whereas ground water was found to be little acidic to neutral range (652-789) COD values (142-224 mg/L) were found to be higher than BOD values (242-564 mg/L) indicating presence of higher load of non-biodegradable wastes in the surface water bodies around Kalna farm
