This research explores the development of a novel slow-release fertilizer coating composed of polyvinyl alcohol (PVA), tapioca starch, and modified rice husk char. The study focuses on the optimal production of rice husk char at 600°C, which facilitates enhanced silica and reduced carbon contents, improving its functional properties in the coating matrix.

In points of annual crop farming and close to residential the contribution of inorganic fertilizers to the total concentration of nitrate was estimated, based on the δ 15N-NO3 values, to be as high as more than 60% and the contribution of water waste was around 35-40%. This is the first time isotopic signature of nitrogen-15 in nitrate (δ15N-NO3) was applied as a tool to assess and identify sources of the nutrient in aquatic environment.

In the present study Bovine digesta, a major slaughter house waste has been recycled as organic fertilizer. Bovine digesta collected was sun dried for 3 days, powdered and was subjected to physicochemical analysis - BOD, COD, pH and TDS. Bovine digesta has 1.35% Nitrogen, 0.72% Phosphorous and 0.515% Potassium. Hence, it has been evaluated as organic fertilizer in Maize at various percentages like 75%, 100%, 125% and 150% equated with nitrogen content of urea. Urea and farmyard manure has been used as inorganic and organic fertilizer control for Bovine digesta.

The increase in population and reduction of available land and water resources are major concern for agriculture to meet food requirement. The possible growth in agriculture can be achieved by increasing productivity through soil, water and nutrient management supported by an effective use of modern technology like nanotechnology. The small size, high specific surface area and reactivity of nano fertilizers compared to bulk fertilizers may increase the solubility, diffusion and availability of nutrients to plants and enhance crop productivity.

A microgranule fertilizer was designed for localized fertilization of soil with controlled release of nutrients. The microgranule matrix was fortified with proteins, which were obtained from food industry byproducts or waste, i.e., whey protein from milk serum, soy protein from soy isolate and egg white protein from chicken egg white powder.

In many parts of the world food security is being affected due to declining quality and/or quantity of the soil resource base and climate change. In this context, farming with zeolites has drawn attention. Zeolites are natural aluminosilicates present in rocks in different part of the world. Use of zeolite has gained a momentum in the recent past owing to multitude of benefits accrued from them. Clinoptilolite Zeolites are useful in agriculture because of their large porosity, cation exchange capacity and selectivity for ammonium and potassium cations.

The aim of this study was to study the use of a beads-based biofertilizer in crop production. The study focuses on the production of a beads-based biofertilizer containing spores and vegetative cells of Bacillus megaterium (B. megaterium) VACC 118. It also evaluated the quality of the biofertilizer and its effects on the growth and yield of cabbage. The results show that the density of B. megaterium in the beadsbased biofertilizer reached 4.34×1010 CFU/g and did not change after 6 months of storage. The degree of swelling of the beads was 1.

The experiment was conducted to study the nitrogen release potential of Entisol and Vertisolas influenced by the treatments of neem coated urea (NCU), DAP, NPK briquette, NP briquette, urea briquette and crotonylidene diurea (CDU). The application of all the sources of nitrogenous fertilizers increased the N release potential by 336.78 % to 411.49 % over the control in Entisol and by 342.59 % to 470.98 % over the control in Vertisol. The application of NCU in Entisol(7.16 mg kg-1 day-1 ) and the application of NPK briquette in Vertisol (7.

Okra (Abelmoschus esculentus) locally known as „Bhendi‟ also known as lady‟s finger is a popular and most common annual vegetable crop in tropical and subtropical parts of the world. Several insect pests attack okra. Use of synthetic insecticides indiscriminately on okra causes environmental pollution and health hazards to human beings due to pesticide residues. Present day concern for pesticide residue free food has induced intense interest for organic farming.

This publication presents agronomic reasons which have led to the development of controlled-release and stabilized fertilizers. The characteristics, the advantages and the possible disadvantages of controlled-release and nitrification/urease inhibitors are discussed. Particular attention is given to problems of legislation, registration, methodology and standardization. Leading manufacturers and their product ranges are listed.

The growing tissue then begins to release more hormones to keep everything in the right condition. How- ever, if fertilization does not occur, the continued preparations in the uterus are unnecessary. The body realizes this near the end of the four- week period of the menstrual cycle. At this time, the level of LH decreases, the corpus luteum breaks down, and the level of progesterone decreases. Without this hormone, the uterine lining no longer remains intact. Instead, the lining breaks down.
