The rat preprotachykinin (PPT) gene encoding the neuropeptides substance P (SP), neurokinin A (NKA), neuropeptide K (NPK), and neuropeptide gamma was isolated from a lambda Charon 4A genomic library. Two overlapping clones contained all of the exons present in beta-PPT, including some 7 and 9 kb 5' and 3' flanking sequence, respectively. The presence of 1 major and 2 minor transcription initiat...

A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...

This study aims to evaluate the effect of Entada abyssinica and Tithonia diversifolia hidden on ground compared NPK (17-17-17), only in organomineral combination growth yield corn. The treatments, three repetitions, consisted a witness (T0), five levels fertilizer contribution: biomasses E. T. diversifolia, NPK, +NPK T +NPK. The observations had related parameters production. results obtained...

The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...

The must used to make sparkling wine has a low pH value and moderate sugar content, its potassium content can have strong influence. An excess of often leads an insufficient supply magnesium, since antagonistic effect on and, consequently, poorer photosynthesis quality the must. aim this study was determine whether application foliar fertilizers based phosphorus, amino acids could reduce leaf a...

Crop rotation system of maize and beans, established at Rubona (Rwanda) from 1984 to 1992, was used to evaluate different types and rates of fertilizers in improving the productivity of acid Oxisols. Continuous cropping of maize followed by beans for a period of 8 years gave no yield in control plots. A single application of 2 t per ha of lime increased significantly (p = .01) the soil pH, Ca2+...

Effects of different fertilizers on organic carbon (C) storage and turnover of soil fractions remains unclear. We combined soil fractionation with isotope analyses to examine soil organic carbon (SOC) dynamics after 25 years of fertilization. Five types of soil samples including the initial level (CK) and four fertilization treatments (inorganic nitrogen fertilizer, N; balanced inorganic fertil...

Vermicomposts processed commercially from food wastes and paper wastes were applied, to 4.5 m(2) field plots, under high plastic hoop tunnels, at rates of 5 or 10 tha(-1) to evaluate their effects on the growth and yields of strawberries (Fragaria ananasa) var. 'Chandler'. The vermicomposts were incorporated into the top 10 cm of soil and supplemented, based on chemical analyses, with amounts o...
