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 2015-09-29 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment was conducted at farmer’s field of Anandapur, Mangalpur VDC-3, Chitwan, Nepal during winter season from September 2006 to February 2007 to study the effects of nitrogen and plant population on maize. Fifteen treatment combinations consisting of five levels of nitrogen: 0, 50, 100, 150 and 200 kg N/ha and three levels of plant population; 55555 plants/ha (60 cm × 30 cm spacing), 66666 plants/ha (60 cm × 25 cm spacing) and 83333 plants/ha (60 cm × 20 cm spacing) were tested in factorial randomized complete block design (RCBD) with 3 replications. “Rampur Composite” variety of maize was planted on sandy silt loam and strongly acidic soil having medium in total nitrogen (0.123%), high in soil available phosphorous (77.56 kg/ha) and low in soil available potassium (23.25 kg/ha). The research findings revealed that each level of nitrogen significantly increased grain yield upto 200 kg N/ha. The grain yield (6514.48 kg/ha) obtained under 200 kg N/ha was significantly higher than that of 0, 50, 100 and 150 kg N/ha. The percent increment in yield due to application of 50, 100, 150 and 200 kg N/ha was to the extent of 62.11, 104.74, 135.68 and 154.74%, respectively over control. Significant effect on grain yield due to different levels of plant population was observed. The grain yield (5113.46 kg/ha) obtained under 66666 plants/ha was statistically at par with that under 83333 plants/ha, but significantly superior over that under 55555 plants/ha. The interaction between different nitrogen levels and plant densities on grain yield showed that the highest grain yield (6925.79 kg/ha) was obtained under treatment of 200 kg N/ha + 66666 plants/ha. The yield attributes namely number of cobs/plant, cob length, cob diameter, number of grain rows/cob and 1000 seed weight significantly increased with increasing N levels and decreasing plant population levels. The number of barren plants/ha decreased with increasing levels of N but increased with increasing levels of plant population. The net return (Rs. 42188.74/ha) and benefit:cost ratio (1.67) obtained under 200 kg N/ha were significantly highest than that obtained under other levels of nitrogen (150, 100, 50 and 0 kg N/ha). The plant population of 66666 plants/ha gave the highest net returns (Rs. 25812.28) which was 10.19 and 49.64% higher than that of 83333 plants/ha and 55555 plants/ha, respectively. The benefit: cost ratio (1.44) obtained under 66666 plants/ha was significantly higher than that of 55555 and 83333 plants/ha. The interaction between different nitrogen levels and plant densities on economics of maize production showed that significantly highest net return (Rs.48606.98) and B:C ratio (1.78) were under treatment of 200 kg N/ha + 66666 plants/ha. The highest grain yield and maximum profit were obtained when maize variety “Rampur Composite” was planted with 200 kg N/ha and plant population level of 66666 plants/ha (60 cm × 25 cm spacing).

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 (...).

Book excerpt: Maize is among the most widely spread and widely used crops of the world, used for cereals for over 4 billion humans, as food for farm animals, and as a source material for biofuel production. Yet there are relatively few books on the cropping system of this important crop. This book, Maize Agroecosystem, is a concise treatise dealing with agronomy, soil fertility, and productivity of maize. The information is global in nature and considers recent developments in all maize cropping belts. The "global maize agroecosystem" is a conglomerate of several "maize cropping belts" that flourish on different continents. The impact of nutrient management on the productivity of maize agroecosystems is the main focus of this book. The book includes the history of maize growing, the kinds of soil needed, nutrient dynamics, the use of soil organic matter, the physiology and genetics of maize, and integrated nutrient management. It presents comprehensive knowledge regarding the physicochemical dynamics of the three major nutrients: nitrogen, phosphorus, and potassium. Also covered is how fertilizers impinge on soils of maize farms and their impact on soil and groundwater quality. The impact of crop genotype on soil nutrient dynamics and productivity is also highlighted. The information provided here will be highly useful to students at colleges and universities in the fields of agricultural sciences and environmental science and ecology, and the book also functions as valuable resource for researchers and professors in crop science. Several figures and tables are included that describe and summarize the impact of various agronomic/fertilizer management procedures on crop productivity.

This book was released on 2012-03-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Study was done to assess effect of continuous application of plant nutrients through organic and inorganic sources and its combination on crop yield, growth, uptake of both macro and micro nutrients and economics of maize. The experiment consisted of 12 treatments comprising chemical fertilizers, organic manure, Azotobacter bio-fertilizer and their combinations. The results revealed that the growth of maize crop in terms of plant height at 45 DAS and at harvest, LAI and SPAD chlorophyll meter values at 30 and 45 DAS were maximum by applying 100 % NPK + FYM 10 t/ha. The crop attained highest CGR (20.09 and 23.23 g m-2 day-1, respectively) between 30-45 and 45-60 DAS and RGR at 45-60 DAS when fertilized with 100 % NPK + FYM 10 t/ha. Highest maize grain, stover and biological yield (4075, 6055 and 10155 kg ha-1) were obtained by applying 100 % NPK + FYM 10 t/ha. Soil enrichment with 100 % NPK + FYM 10 t ha-1 resulted in highest monetary returns of Rs. 31253/ha. The maximum B.C. ratio (1.91) was accounted by 100 % NPK + Azotobacter with statistical equivalence with 150 % NPK, 100 % NPK alone or in combination with Zn, Zn + S and FYM 10 t/ha.

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
