Uptake Of Nutrients

In the dry summer 1969 the effect of irrigation and supply of available nitrogen on the production of dry matter and on the N, P, K, Mg, and Ca content of the aerial parts of spring wheat was studied on the basis of samples collected at various stages of development from a field trial. Shoots collected from the irrigated plots (30 mm water on June 9 and 30 mm water on June 17) in the middle and at the end of June had a higher content of all the nutrients studied than those from the nonirrigated plots although at the latter date also the dry matter yield was markedly increased by irrigation. Later, the larger production of dry matter on the irrigated plots decreased this difference and resulted in equal or even somewhat lower contens of N, P, K, Mg, and Ca in the ears and straw, and also in the grains. An improvement in the supply of available nitrogen tended to increase the dry matter yield and the content of K, Mg, and Ca in the vegetative parts of the plant; the N content was increased also in the ears and grains. The positive interaction of water and nitrogen supply was distinct in the production of dry matter and in the uptake of nutrients. The high grain yields produced by irrigation and good or very good nitrogen supply were attributed, at least partly, to the more intensive uptake of nutrients during the period of vigorous growth in June. It was emphasized that the improvement of the efficiency of plant production by irrigation and placement of fertilizers may result in an impoverishment of the soil of other nutrients.

Uptake Of Nutrients

Simazine applications of 1.5 p.p.m. to soil in pots in a glasshouse increased dry matter yields and uptake of nitrogen in corn only when additional nitrogen was applied to the soil. The proportions of protein and non-protein nitrogen in the topgrowth were not affected. Application of simazine at this rate without addition of nitrogen resulted in increased leaf area but did not significantly affect yield. Simazine provided a stimulus to the plant early in its life and enabled it to grow faster than the control plant. When the supply of available nitrogen was exhausted the simazine effect decreased. When incubated with soil, simazine did not increase mineralization of soil organic nitrogen, nor did it have any effect on immobilization of mineral nitrogen. Simazine applied at 0.06 p.p.m. in solution culture increased the yield of corn tops by 36%, the uptake of nitrogen by 37%, phosphorus by 25%, magnesium by 24%, and potassium by 41 %. It had no effect on the yields of roots. The results suggest that simazine increased plant growth by a direct effect on plant metabolism and not through any interaction with the soil.

A field experiment was conducted at Dr.P.D.K.V., Akola (M.S.) during 2011-2012 and 2012-2013. The experiment comprised of nine treatments involving 2.5 and 5t FYM ha-1, 1 and 2t sheep manure ha-1, 2 and 4t vermicompost ha-1, 25:50 and 12.5: 25 kg ha-1 NP through inorganic and control. Among different treatments, the application of 4t vermicompost ha-1 resulted in significantly increased pod yield (26.19 q ha-1), seed yield (17.62 q ha-1) and dry matter yield (46.68 q ha-1) as well as quality such as L-Dopa (3.63%), protein (26.79%) and test weight (111.69 g) of kawachbeej over control and superior over rest of treatments. The highest seed yield 184.04% and L-DOPA content 101.96% was observed with 4t vermicompost ha-1 over control. The similar trend of results was noticed in uptake of macro (N, P, K ,S) and micronutrients (Fe, Mn, Zn, Cu) of kawachbeej and it was at par with treatment 5t FYM ha-1 and 25:50 kg ha-1 NP through inorganic, respectively.

Npk Fertilization

An experiment was conducted for 3 yr to compare the effects of fertilization of mixed forage with fresh and composted chicken manure and inorganic NPK. Fertility amendments were applied each year at three N levels and an unfertilized treatment was included. The experiment was conducted in two hay fields near Truro, Nova Scotia. Dry matter yield and forage N, P and K contents are reported for the 1992 and 1993 seasons. The nutrient content of the amendments as well as the efficiency of P and K use are discussed. Soil Mehlich 3-extractable P and K and KCl-extractable N were measured at two depths in September 1993. By the final year of the experiment, compost amendments produced yields as high as the recommended rate of NPK fertilization at both sites on both harvest dates. Medium rates of compost application also resulted in tissue N levels as high as or higher than the equivalent NPK treatments. The medium rate of manure application was equivalent in yield and tissue N to the compost treatments at the Acadia site, but had slightly lower yields and tissue N content at the Pugwash site. Compost P and K were relatively inefficiently used by the forage; this resulted in increased levels of Mehlich 3-extractable P and K in the 0- to 15-cm layer of the compost-amended plots. It was concluded that fertilization with compost or inorganic NPK, supplying equal amounts of N, can result in comparable yields and quality of forage.

Set Up

The yield of sugar beet has increased significantly in the last 20 years, as data on beet yields from Südzucker AG show. This led to the question of how the increased yield influenced the nutrient uptake of root and top. Therefore, beet and top were harvested in field trials set up to optimize the fertilization of sugar beet and, in addition to the yields, the concentrations of macronutrients and micronutrients in root and top were measured. A total of 114 environments were used for these studies and current data for nutrient uptake and nutrient export from sugar beet were determined. Root yields ranged from 65 to 115tha–1 and the top yields from 13 to 72tha–1. This corresponded to a dry matter yield of 14 to 26tha–1 for roots and to as little as 3.0 to 9.6tha–1 for tops. However, since the nutrient content in the roots was significantly lower than in the tops, less than 50% of the total uptake was found in the roots at harvesting time: N (49%), Mg (44%), K (36 %), Ca (34%), S (32%) and Na (12%). Among the macronutrients, it was only phosphorous which showed with 60% a higher amount of the nutrients in the roots than in the tops (about 40%). The results provide valuable information for a review and adaptation of current nutrient tables,the nutrient balance and, ultimately, fertilizer assessment.

P Application

Flax (Linum usitatissimum L.) was grown in two growth chamber experiments on a total of 16 Black Chernozemic soils varying in content of Mg, Ca, P, and Zn. On three of the soils, dry matter yield of flax increased in response to application of P. Phosphorus availability was greater with broadcast than with banded fertilizer applications. Increased yield in response to Zn application was observed on one-half of the soils. Applications of P that increased P level in the tissue above 0.46% led to consistent but nonsignificant decreases in yield and reduced the level of Zn in the tissue. Zinc fertilization increased Zn and decreased P level in the tissue. Yield response to P application was not strongly related to soil chemical parameters measured, but increased as tissue P level decreased and tissue Zn level increased. High levels of soil Mg and soil pH and high tissue levels of Mg and P were the factors most closely associated with a yield response to Zn applied with P.

Abstract Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of variance (ANOVA) by using the general linear model (GLM) procedure in Statistical Analysis System (SAS) (2003) version 9.1. Results The results revealed that highest forage dry matter yield was recorded for variety ILRI-6984 harvested every 40 days (26.8 t DM ha−1) and for var. DzF-552 when harvested every 60 days (24.1 t DM ha−1) (P<0.001). While crude protein concentration tended to decline as age at harvest increased, there was little consistency in the pattern. Crude protein yields were also inconsistent across treatments but ILRI-6984 harvested every 40 days produced the highest yields (6.5 t ha−1) (P<0.001). Conclusion These preliminary findings need to be confirmed under field conditions on a large scale along with longer-term studies to examine the longevity of the stands at these harvest frequencies. Irregular harvesting based on stage of maturity should be compared with fixed inter-harvest intervals.
