Soil test crop response (STCR) correlation studies were carried out in Vindhyan alluvial plain during 2001 to 2004taking IR-36 as test crop to quantify rice production in the context of the variability of soil properties and use of balanced fertilizers based on targeted yield concept. The soils were developed on gently sloping alluvial plain with different physiographic settings and notable variation in drainage condition. Soil properties show moderate variation in texture (loamy to clay), organic carbon content (4.4 to 9.8 g/kg), cation exchange capacity (10.2 to 22.4 cmol (p+)/kg) and pH (5.3 to 6.4). Soil fertility status for N is low to medium (224 to 348 kg/ha), P is medium to high (87 to 320 kg/ha) and K ranges from medium to high (158 to 678 kg/ha).Database regarding nutrient requirement in kg/t of grain produce (NR), the percent contribution from the soil available nutrients [CS (%)] and the percent contribution from the applied fertilizer nutrients [CF (%)] were computed for calibrating and formulating fertilizer recommendations. Validity of the yield target for 7 and 8 t/ha was tested in farmers' fields and yields targets varied at less than 10%. The percent achievement of targets aimed at different level was more than 90%, indicating soil test based fertilizer recommendation approach was economically viable within the agro-ecological zone with relatively uniform cropping practices and socio-economic conditions.

Mosquitoes are the vectors of several life threatening diseases like dengue, malaria,
Japanese encephalitis and lymphatic filariasis, which are widely present in the north-eastern
states of India. Investigations on five local plants of north-east India, selected on the basis of
their use by indigenous communities as fish poison, were carried out to study their mosquito
larvicidal potential against Anopheles stephensi (malaria vector), Stegomyia aegypti (dengue
vector) and Culex quinquefasciatus (lymphatic filariasis vector) mosquitoes. Crude Petroleum
ether extracts of the roots of three plants viz. Derris elliptica, Linostoma decandrum and
Croton tiglium were found to have remarkable larvicidal activity; D. elliptica extract was
the most effective and with LC50 value of 0.307 μg/ml its activity was superior to propoxur,
the standard synthetic larvicide. Half-life of larvicidal activity of D. elliptica and L. decandrum
extracts ranged from 2-4 days.

Purpose:
This meta-analysis aimed to determine the efficacy and safety of antioxidant supplementation for treating erectile dysfunction (ED).
Materials and Methods:
We systematically searched MEDLINE, Embase, and the Cochrane Library for double-blind, randomized, placebo-controlled trials of oral antioxidant supplementation in men with ED. Erectile function was assessed by the International Index of Erectile Function-Erectile Function domain (IIEF-EF) score. Using random-effects meta-analysis models, antioxidant and placebo groups were compared for erectile function using the mean difference in IIEF-EF score adjusted to a 6–30 scale and for side effects using the log risk ratio.
Results:
The review included 23 trials of 1,583 men (median age 51 years) treated with antioxidant supplementation or placebo for a median of 12 weeks (range, 4 weeks to 6 months). Antioxidant supplementation significantly improved erectile function compared to placebo, with a mean difference of 5.5 points (95% confidence interval [CI]: 3.7 to 7.3; p<0.001) on the IIEF-EF. In meta-regression, the treatment benefit was greater in men with more severe ED (p<0.001). Side effects were uncommon, none were serious, and the frequency was comparable between antioxidant (3.8%) and placebo (2.1%) groups (log risk ratio=0.36; 95% CI: -0.24 to 0.97; p=0.24).
Conclusions
Antioxidant supplementation appears safe and significantly improves erectile function in men with ED, particularly those with more severe symptoms. Limitations of this review included unknown long-term efficacy and safety and the inability to make specific product and dosing recommendations due to the variety of antioxidants and regimens studied.
