This book was released on 2020-10-26 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2018 in the subject Agrarian Studies, grade: 8.5, , course: Agronomy, language: English, abstract: The aim of this study is to study the effect of integrated nutrient management on the growth and yield of kharif Maize and to work out the economics of different nutrient management treatments. As the chemical’s fertilizers play an important role in plants life so that these chemicals should not be avoided completely as they are the potential sources of the high amount of nutrients in easily available forms. These fertilizers greatly affect enzymatic activities in the soil profile but poor management of the chemical fertilizers has a key role in lowering the yield productivity and deteriorate the soil health also. So, to achieve optimum crop production, there is a need to use the combination of organic sources, inorganic sources, bio-fertilizers. Maize (Zea mays L.) requires the nutrients i.e., macronutrients as well as micronutrients for obtaining the higher crop growth and yield. The micronutrients content in organic manure may be sufficient to meet the crop requirement but the low soil fertility is the major problem to maintain sustainability in production. The application of organic manure do not produce optimum yield due to low nutrient status but they play a direct role in plant growth by the mineralization they provide the essential nutrients which furthermore improves the physical and biological properties of the soil. The use of organic plays an important role in maintaining soil health due to the build-up of soil organic matter, beneficial microbes. “Biofertilizer” is a substance that contains living organisms. It promotes growth by increasing the supply or availability of primary nutrients to the host plant. These are not fertilizers because fertilizers directly increase soil fertility by adding nutrients. They add nutrients through the natural processes of fixing atmospheric nitrogen, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth promoting substances. Azotobacter is dominant among the free-living forms of nitrogen fixers. It has been used extensively as a production technology in many countries and there were 20-29 percent increase in yield. Hence, the judicious application of these combinations can sustain soil fertility and productivity. In general, scheduling of fertilizers is based on the individual nutrient requirement of the crop and the carry-over effect of manure and fertilizer applied to precede crop is ignored.

This book was released on 1988 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was conducted from February to September 1987 at the Central Experimental Station, UPLB (a) to evaluate the efficacy of rice straw and maize stover mulch in optimizing growth and yield of maize, (b) to determine the effect of nitrogen fertilization under simulated dry-land farming on maize production, and (c) to measure the residual effect of mulch and nitrogen using maize, mungbean and cowpea as the test crops. Nitrogen and mulch application, but not irrigation, significantly affect most of the parameters in this study. Nitrogen application increased plant height, crop growth rate, leaf area index, nutrient uptake, grain yield and dry matter production. It lowered leaf area ratio and barrenness of maize ears and induced early silking in maize. As aresult of luxuriant growth, nitrogen application helped reduce the maximum soil temperature and increased the water utilization by maize plants. Rice straw was a better mulching materials than maize stover. Mulch, particularly rice straw, improved IDM accumulation, plant heit, leaf developement, grain yield and nitrogen uptake. The effectiveness of rice mulch in conserving soil moisture and maintaining a low maximum soil temperature especially when soil moisture became low was observed. Residual of nitrogen application and mulching treatment were detected but the response depend on the test crop species used. The most clear-cut case was observed with mungbean, where residual mulching effect resulted in a two-fold increase in bean yield. The residual (...).

This book was released on 2015-07 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: In laboratory experiment, dynamics of various P fractions were studied with enriched rock phosphates with Phosphobacteria. The treatment, TRP EnFYM with PB recorded highest quantity of all the P fractions irrespective of soil type and were comparatively superior over MRP EnFYM with and without PB. The PB favourably influenced various P fractions irrespective of soils and rock phosphates. In field experiments, the grain yield of maize was highest (6.62 t/ha) in 100 % P as TRP EnFYM with PB (T14) over SSP in black calcareous soil. The highest phosphorus use efficiency, physiological efficiency and B: C ratio were highest in T14. In red non-calcareous soil, highest grain and stalk yields were observed in T2 (100% P as SSP) and it was on par with T8 (100% P as MRP EnFYM with PB). The increase in P levels increased the grain and stalk yield.The PUE was highest in T2 followed by T8 and the increasing levels of P recorded increase of PUE. The physiological efficiency was highest in T2. The highest response ratio was registered in T6. The highest B: C ratio was recorded in T7 followed by T

This book was released on 2009 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project began in April 2007 when the maize was planted at four farm locations within the Kakamega District. Cattle manure was applied to half of the plots at each farm site, and inorganic fertilizer was applied to the remaining plots, both in accordance to nutrient recommendations from the Kenya Agricultural Research Institute's (KARI) Regional Research Center in Kakamega. The N rate from the inorganic fertilizer was equivalent to the dry-weight rate of total-N applied in the cattle manure, allowing for a direct comparison.
