F are a critical component of the global carbon (C) cycle, storing more than 1 × 1015 metric tons of carbon in biomass, detritus, and soils (Dixon et al. 1994). Forest C storage is an important ecosystem service, locking upC thatmight otherwise exist in the atmosphere as carbon dioxide (CO2), a potent greenhouse gas. In the northern hemisphere, forests are estimated to sequester up to 7 × 108 m...

The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

Among the single treatments tested under in vivo addition of well decomposed FYM 20 tons per hectare as soil amendment recorded minimum wilt incidence of 3.75, 24.76 and 48.25 % at flowering, fruit formation and ripening stages of chilli crop, respectively, with 61.31 q ha fruit yield as compared to check (42.50 q ha). Dual application of Trichoderma viride 0.16 t ha + FYM 20 t ha recorded mini...

At least 7 species of Noctuid moths have been reared from caterpillars collected beneath trash in cane fields, and some at least feed at night on leaves of young ratooning sugarcane, the chief offender being Mythimna phaea Hamps. Feeding appeared to be initiated by onset of darkness, but a reduction in numbers feeding occurred before dawn. Natural enemies included 6 Tachinid flies, an Ichneumon...

Once-a-day (OAD) milking offers a major opportunity to improve labour output on New Zealand farms. However few full lactation studies have been undertaken to investigate the effect of this strategy on the productivity of the farm system. A trial was established in 2000 to measure the effect of milking frequency and breed in farm systems where stocking rate was adjusted to equalise per hectare f...

in order to determine the effect of potassium silicate solution with elements of macro and micro elements on agronomic traits of rice, tarom, a field experiment in paddy fields galogah city - village marbles of the crop year 2014 was conducted. the results showed that the highest plant height (013/180 cm) to 2 liters per hectare and no interaction effects of potassium silicate elements. the res...

Observed properties imparted to soils at economical levels by a wide range of different polymer emulsions are discussed. The results of pot experin~ents are summarised indicating how specifically treated sand can reduce soil moisture evaporation, increase temperatures in wet soils and reduce leaching losses of fertilizers. Early shoot counts from four separate replicated field experiments plant...
