Salinity causes cellular damage and limits crop productivity. Accumulation of organic compound is one of the adaptive mechanisms to salinity in plants. The experiments were laid out in a randomized complete block design with three replications at the farmer’s field of Botiaghata, Khulna to investigate the mitigating effects of organic manures on salinity stress in rice genotypes during both aman and boro seasons. Two T. aman rice (salt-sensitive; BR-23 and local cultivar; Mohini) and two boro rice (salt-sensitive; BRRI dhan-29 and salt-tolerant; BINA dhan-8) were used as test crops. Farmyard manure (FYM) and poultry manure (PM) were applied to the soils during final land preparation. There were five treatments namely T0= control (no manure), T1=FYM (5 t/ha), T2=FYM (10 t/ha), T3=PM (4 t/ha), T4=PM (8 t/ha).Thirtyday- old rice seedlings were transplanted in the experimental plots. Salinity caused a significant reduction in growth and yield of both aman and boro rice. Under saline condition, BR-23 (aman rice) produced higher yield than local cultivar Mohini in aman season while BINA dhan-8 produced higher yield than BRRI dhan29 in boro season. Soil amendments with FYM and PM significantly increased the growth, and grain and straw yields of all rice cultivars under saline conditions. Increased nutrient uptake and K+/Na+ ratio in rice were also observed due to application of organic manures. No considerable changes in post-harvest soil properties such as pH, EC, CEC and organic matter status of saline soils were observed by addition of FYM and PM. The present study suggests that soil amendments with FYM and PM improve salt tolerance in rice by increasing K+/Na+ ratio and nutrient uptake. Res. Agric., Livest. Fish.6(1): 11-17, April 2019

In this paper we provide new data about the soil enzyme activity as a biological process, which is an indicator for impacts of factorial combinations of lime and fertilizers applications. Five plots divided into fifteen subplots were sampled for determination of the enzymatic indicators of soil quality, based on the actual and potential dehydrogenase and catalase activities. The research revealed that limed soil samples, in comparison with unlimed ones, resulted in significantly higher soil enzymatic activities (p[0.05) in the upper (0-20 cm), while in the deeper (20-40 cm) layer, only catalase activity was significantly higher (at least at p[0.02). Mineral fertilization, in comparison with its farmyard manuring, led to an insignificant increase in each of the three enzymatic activities determined, excepting catalase activity which was significantly higher (0.05]p]0.02) in the 0-20 cm layer. Based on the absolute values of the enzymatic activities, the enzymatic indicators of soil quality (EISQ) were calculated. The mineral NPK-fertilization and low dose of lime in the 0-20 cm layer, and mineral NP-fertilization and low dose of lime in the 20-40 cm layer proved to be the best variants of fertilization. The enzymatic indicators of soil quality in these variants reached the highest values: EISQ=0.821 and EISQ=0.889, respectively, indicating the presence of high enzymatic activities. It should be emphasized that a balanced application of lime, mineral fertilizers and farmyard manure leads to the formation of favorable conditions for the development of microorganisms, growth of plants and for an intense and lasting enzymatic activity.

Organic And Mineral Fertilizers

Long term productivity and conservation of soils is critical for sustaining agricultural ecosystems. The specific objective of the work reported was to determine the effects of long term application of organic and mineral fertilizers on soil enzyme activity as an index of soil biology and biochemistry. Three key soil enzymes involved in intracellular metabolism of microorganisms and two soil enzymes involved in phosphorus metabolism were selected. Actual and potential dehydrogenase, catalase, acid and alkaline phosphatase activities were determined in the 0-20 cm layer of an eroded soil submitted to a complex fertilization experiment. Results showed that addition of mineral fertilizers to organic (green manure and farmyard manure) fertilizers led to a significant increase in each activity because of increased plant biomass production which upon incorporation stimulates soil biological activity. The enzymatic indicators of soil quality calculated from the values of enzymatic activities depending on the kind of fertilizers showed that by the determination of enzymatic activities valuable information can be obtained regarding fertility status of soils. A weak positive correlation between enzymatic indicators of soil quality and maize yield was established. The yield data demonstrate the superiority of farmyard manure which provided greater stability in crop production. Substantial improvement in soil biological activity due to application of organic fertilizers with mineral fertilizers contribute in maintaining the productivity and soil health.

A high-density planting of three southern highbush cultivars was established in 1994 in southwest Florida to test the feasibility of a non-dormant blueberry production system. A non-dormant system involves continuous application of nitrogen throughout fall and winter, which enables the plants to avoid the normal dormancy cycle and the concomitant chilling requirement. Three nitrogen fertilizer rates and two organic soil amendments (muncipal solid waste compost and acidic peat) were evaluated for effects on maintaining plant growth in this system. In general, increasing N rates from 84 to 252 kg·ha–1 increased plant canopy volume, leaf retention, and rate of new vegetative budbreak. Plant height and volume were consistently greater for plants grown in the compost compared to the peat amendment, but there were no differences in leaf retention or vegetative budbreak between the two soil amendments. Flower bud density and fruit yield were increased in plants grown in the compost compared to the peat, while N rate had no effect on either. Plants in this non-dormant system have shown no deleterious growth effects, suggesting that establishing a blueberry planting in a warm winter climate is feasible under the described conditions.
