NPK fertilizer

Ebook "Recycling of biomass ashes" presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.

One experiment was conducted with 3 treatments and 5 repetitions in a completely randomized design. The treatments including TM1: NPK fertilizers; TM2: manure of ducks fed with silaged banana stem (BM); TM3: manure fed with banana stem, molasses and wort (BM-W). The objective was to evaluate the yield of water spinach when applying duck manure fed with banana stem, molasses and wort in replacing the use of NPK fertilizers.

Microorganisms in the rhizosphere soil play a key role in maintaining the soil fertility, which is a key for successful crop production to meet the increasing global food demand. The aims of this study were to boost growth attributes, yield and nutrient uptake of rice by different treatment combination of plant growth promoting bacteria (PGPB) and NPK fertilizer doses.

The values of potentially mineralizable N estimated using first order kinetics model related well to the observed cumulative MN at 16th week. No significant difference was observed between CF and SRF treatments for available P content in the 2nd week. Significantly higher P content was observed in CF compared to SRF treatment in the 4th week, whereas in the 8th week, some SRFs released significantly higher content than CF.

Chilli is a very important vegetable crop and has a great demand in the processing industry and export market. Chilli crop is more responsive to fertilizer application. Application of fertilizers in excess not only causes environmental problems but also reduces nutrient use efficiency, increases the cost of production and reduces the benefit-cost ratio.

The results of the present investigation indicated that, different pruning treatments and fertilizer levels produced significant effect on growth and yield attributes of guava. The treatment of 45 cm of past season’s growth with application of fertilizer levels of 125% RDF (1000:500:500 g NPK/tree) recorded the significant effect on the growth parameter like plant height, shoot length, shoot diameter and number of leaves per shoot and produced maximum values of all these growth parameters with minimum days of flowering and fruit set. The maximum yield (60.41 kg/tree and 16.79 t/ha.

A study was conducted in an ongoing field experiment started during Rabi 1988-89 in calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The experimental design was split-plot with four fertilizer levels (0, 50, 100 & 150% NPK) in main plots and four levels of manures (no manures, compost @10 t ha-1 , crop residues and compost @10 t ha-1 plus crop residues) in sub-plots.

The present investigation was carried out at Research farm, Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, SHUATS, Allahabad (U.P.) during the Rabi season of 2019-20 with the objective to response of different levels of N P K and Neem cake on soil health, growth and yield attributes of Field pea (Pisum sativum L.). The experiment was laid out in a Randomized Block Design with nine treatment combinations, consisting of three N P K levels (0, 50 and 100%) and Neem cake (0, 50 and 100%).

The field experiment was conducted the year 2014-2015 on the old long-term fertilizer experiment started since 1983 to assess characterization of humus in soil and it’s relation with physical and physic-chemical properties of soil under the long – term effect of integrated nutrient management in sorghum wheat cropping system. The study showed that there was fraction of humus tended to decrease with depth and use of organics like subabul and FYM in conjunction with NPK fertilizers exerted a remarkable impact on the distribution and built up of humus fractions in soil.

The study revealed that the guava + banana and guava + eggplant systems were proved to be the most significant intercropping system by improving physio-chemical properties like bulk density, water holding capacity, SOC, available NPK of the soil. The maximum system equivalent yield and economic return were obtained from the same system. Thus the guava + banana intercropping system is not only the best for restoring soil fertility but also obtaining the maximum economic return for guava growers of West Bengal.

An experiment has been conducted to study the effects of application of different level of organic fertiliser and inorganic fertiliser on economic of onion production as well as the fertiliser uptake by plant. From the data it was found that the 25% RDF + 75% N of poultry manure was most effective treatment in respect to economics of onion cultivation for higher net return with greater benefit cost (B: C) ratio as well as uptake of NPK.

Two consecutive field experiments after rice crop were conducted during 2011-12 and 2012-13 in the Crop Research Centre, of Sardar Vallabhbhai Patel University of Agriculture and Technology, Uttar Pradesh. Ten different treatments were implied to evaluate the residual effect of vermicompost and applied inorganic fertilizers on wheat crop. Significantly taller plants than T2 during both the years were measured in those treatments where 4 ton vermicompost was applied in rice.

The results of the study revealed thaturea was most effective in inhibiting the fungal growth at all the tested concentration. It was also found that soluble NPK and Potassium nitrate promoted the fungal growth at all the concentration. Among biorationals, bromonitropropanol gave the highest mycelial inhibition (73.72%), while sodium and potassium bicarbonates at lower concentration promoted the fungal growth, but inhibited the growth at higher concentration.
