NMDA receptor antagonists block conditioned fear extinction when injected systemically and also when infused directly into the amygdala. Here we evaluate the ability of D-cycloserine (DCS), a partial agonist at the strychnine-insensitive glycine-recognition site on the NMDA receptor complex, to facilitate conditioned fear extinction after systemic administration or intra-amygdala infusions. Rat...

Soaking potato tuber pieces for 15 min in 8,000 mug/ml of oxamyl just before planting reduced the number of Globodera rostochiensis cysts that developed on potato roots, but this treatment was phytotoxic. Five foliar applications of 1.12 kg a.i./ha of oxamyl or carbofuran at 10-day intervals beginning when 90% of the plants had emerged suppressed increase in G. rostochiensis densities. Similar ...

The growth and yield of Egusi melon in response to application of an Organo-mineral fertilizer was investigated. The Organo-mineral fertilizer was Cow-dung generated from an Abattoir fortified with inorganic Nitrogen. The fertilizer had a pH of 6.1; 61.2 g kg Organic Matter; 35.5 g kg -1 -1 Organic Carbon; 3.6g kg Nitrogen; 372.54 mg kg Available Phosphorus and 14.8cmol kg -1 -1 -1 Exchangeable...

INTRODUCTION Biotechnology with its promise to revolutionize agriculture around the world is assuming an increasingly greater role in India’s agricultural research. The indiscriminate use of chemical pesticides has affected humans and their environment and insect pests remains to be one of the major limiting factors in sustaining the productivity of various crops. The concept of IPM for sustain...

Plots naturally infested with Rotylenchulus reniformis were sampled in the spring of 2006 and 2007 at depths of 15 and 30 cm in the bed, furrow over the drip tape, and "dry" furrow, and at approximately 40 to 45 cm depth in the bed and dry furrow. Then, 1,3-dichloropropene (Telone EC) was injected into the subsurface drip irrigation at 46 kg a.i./ha, and 3 to 4 weeks later the plots were resamp...

The IGR, methoprene, in 3 solid (Altosid Pellet, Altosid XR Briquet and a granular) and a liquid formulation (A.L.L.) was evaluated against chironomid midges in experimental ponds. The A.L.L. was applied at 0.293 liters/ha (0.015 kg AI/ha) and at 5.86 liters/ha (0.28 kg AI/ha). The granules, pellets and briquets were applied at 13 kg/ha (0.17 kg AI/ha), 5.6 kg/ha (0.22 kg AI/ha) and one briquet...

this study evaluated the irrigation water management and different amounts of boron fertilizer affacts on yield and and water use efficiency of sugar beet. the two-factor factorial design in randomized complete block with three replications of irrigation and different levels of boron fertilizer for three years (2000-02) was designed in qazvin. the main four irrigation treatments were t1, t2, t3...

Sugarcane (Saccharum officinarum L.) is a multi-purpose crop, mainly planted in South-western (SW) parts of Iran. However, the capability of sugarcane farms to sequestrate carbon into soil and plant is not well documented. In this research, the carbon sequestration in sugarcane plant and soil in a ratooning traditional cultivation system at the Amirkabir Sugarcane Agro-Industry Complex...
