Effect of potassium nutrition on growth and dry matter accumulation of lotus

Effects of nitrogen application on dry matter accumulation and translocation of different genotypes of summer maize

Experiments for controlling the soil matric potential of 0～-20 cm soil layer by use of irrigation and drainage have been conducted with lysimeters to study its effect on dry matter accumulation, nutrition and grain yield of winter wheat.

Effects of plant densities on accumulation of dry matter and population trends of Tanshan 21 under the high yield condition;

Studies on effect of continuous cropping on photosynthesis and accumulation of dry matter in peanut were carried out under field condition.

The results show that the accumulation of dry matter and seed yields all increase with nitrogen rates,but that the weight of 100 seeds increase little except that of Dongnong 42.

The effect of different nitrogen fertilizer level on the changing trends of plan about the height, leaf area index(LAI), dry matter accumulation, distribution and yield of Kennong4 were studied in this experiment.

The results showed that sweet pepper has a good growth protential,larger single fruit weight,more dry matter and higher yield under the appropriate moisture(60%-70%) during the whole growth period.
