We investigated the functional state of the kidneys in 20 patients with bronchiectasis, 13 with bronchial asthma and 7 with lung abscesses. Zimnitsky's test was normal in 12 patients, isogppostenuria and nocturia were found in 9, and nocturia in 19. Fonno's test was carried out in 31 patients. In 18 it turned out to be normal, in 13 patients a violation of the excretory function was revealed. Albuminuria was observed in 8, microhematuria - in 4, urobilinuria - in 17. The level of residual nitrogen was normal in 39 and increased in one patient.

The objective of this study was to evaluate the effect of residual nitrogen (N) on pastures of Mombaça grass and its impact on pasture structure and the nutritive value and performance of beef cattle. The experiment analyzed randomized blocks subdivided into plots, with three replications. The research focused on a number of pastures having received three annual doses of N (100, 200 and 300 kg ha-1) from 2015 to 2017, with no N fertilization in 2018. The results indicated that pastures under residual effect of 300 kg ha-1 of N were characterized by higher (P<0.05) rates of forage accumulation than those under the residual effect of 100 kg ha-1 N. Furthermore, this study indicated no effect (P>0.05) on the pasture nutritive value and average daily gain (0.490 kg day-1). The stocking rate was higher (P<0.05) in pastures under the residual effect of 300 kg ha-1 of N, and lower in those at 100 kg ha-1 of N, while weight gain per area followed the trend observed in the stocking rate. The results thus suggest that the suspension of N fertilization for one year after three years of sequential fertilization was responsible for an immediate loss of 50 and 55% of the productivity of plants and animals, respectively. Highlights: Fundamental nitrogen fertilization to ensure pasture productivity. The use of nitrogen fertilization has been limited by cost, due to the extension of the areas involved and the need for frequent applications. We suspended nitrogen fertilization for one year after using the same doses of nitrogen for three years in order to evaluate a possible residual effect on plant and animal production. Suspending the N fertilization of Mombaça grass for one year after three years of sequential fertilization with the same doses leaves a residual effect on the pasture structure and performance of beef cattle. The suspension of nitrogen fertilization reduces the rate of forage accumulation by an average of 50%, causing a 55% reduction in animal productivity.

A field experiment was conducted during rabi seasons of 2017-18 and 2018-19 at College farm, Agricultural College, Bapatla, situated at 8 km away from the Bay of Bengal in the Krishna Agro-climatic Zone of Andhra Pradesh state of India to study the influence of dates of sowing and residue levels of nitrogen on growth, yield and uptake of sorghum under zero- till conditions in coastal rice fallows. The experiment was designed in RDB with factorial concept and replicated thrice. The treatments consisted of three dates of sowing (Factor-1): S1: 49 MW (5th December); S2: 50 MW (15th December); S3: 52 MW (25th December) and four residual nitrogen levels (Factor-2) applied to the previous rice crop: N1-60 kg, N2-80 kg, N3-100 kg and N4-120 kg N ha-1. Sorghum was grown as a residual crop under zero tillage in rice fallows. Significant higher improvement in drymatter (10395 and 10269 kg ha-1), length of spike (24.8 and 24.5 cm), grain (3839 and 3602 kg ha-1) and stover yields (7446 and 7298 kg ha-1) and nitrogen uptake by grain (51.9 and 42.9 kg N ha-1) and stover (42.0 and 39.9 kg N ha-1) was recorded in early date of sowing i.e. 49 MW in both the seasons 2017-18 and 2018-19, respectively, and among the residue nitrogen levels 120 kg N ha-1 showed highest drymatter (10661 and 10484 kg ha-1), length of spike (25.0 and 24.8 cm), grain (4078 and 3815 kg ha-1) and stover yields (7518 and 7443 kg ha-1) and nitrogen uptake by grain (54.6 and 46.6 kg N ha-1) and stover (44.3 and 42.1 kg N ha-1) compared to other nitrogen levels in both the seasons. Based on above results, early sowing of sorghum with high residue nitrogen levels could be recommended to small and marginal farmers in coastal belts of India for higher productivity.
