learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Fertilized black soil samples are prepared by mixing desired amounts of fertilizers in the black soils having 10% gravimetric moisture content. Two black soil samples were collected from two different locations of Maharashtra State (India). Three different chemical fertilizers viz., Urea, Di-Ammonium Phosphate and Potash are used. Measurements of complex dielectric constants of these soil sampl...
AbstractYield of tea plant (Camellia sinensis L) is reduced in old farms due to the compactness of the soil around the roots. As a consequence, water flow and air exchanges will be reduced. Operating in the thin layer of soil where plant roots develop, earthworms improve recirculation of the nutrients and microbial metabolites and stimulate nutrient uptake. Evaluation of the biological effects ...
The aim of this study was to investigate the effect of chemical fertilizers of nitrogen, phosphorus, sulfur and biofertilizer on some growth indicators of Camelina sativa L. experimental plant during the crop year 2016 in a farm located in Kazerun and as a factorial in the form of complete randomized block design with three replications. Treatments include fertile biofertilizer 2 containing pho...
value of the current global soil P resource is appreciating the range of complexed P forms in soil and their specific issues for crop P accessibility. Soil organic P is especially poorly considered in terms of amounts and future utility. Learning to better utilize all of the different residual P forms in soil is essential to providing a sustainable cycle between agricultural inputs and plant up...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Phosphorus fertilization and liming are alternatives used to increase forage production in Southern Brazil grasslands (Pampa grasslands) avoid its replacement by cultivated exotic crops. However, changes natural soil fertility can significantly affect the equilibrium of vegetation communities. We hypothesized that triple simple superphosphate limestone using would lead greater dry matter botani...
A field study was conducted on hummocky terrain at the Manitoba Zero Tillage Association Research Farm near Brandon, Manitoba, Canada to determine the variability of crop yield as related to landscape position, soil properties, weed populations and plant disease. This information was used to develop a method for delineation of management units related to precision farming. Variable-rate fertili...
In order to investigate the effect of bio-fertilizers on the yield and yield components of flax lines, a study was conducted during 2010 growing season at the Agricultural Research Station of Saatlo in Urmia. A split plot design based on randomized complete blocks with four replications was performed in this study. Main factor (a) consisted of fertilizer application form (a1 = control without n...
introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...
