Utilization of maggot meal in the nutrition of African cat fish

A twelve week feeding trial was carried out to evaluate the growth and nutrient utilization of African catfish (Clarias gariepinus) fingerlings fed varying levels of maggot meal. Maggot meal was produced from a mixture of 25 kg of cattle blood, 70% wheat bran, and 30% saw dust and substituted for fish meal in the fish diet to produce five varying levels of maggot meals- Treatment 1 (Trt 1) contained 0% of maggot meal...

Analysis of land use-land covers changes using normalized difference vegetation index (NDVI) differencing and classification methods

Over the last decade, the normalized difference vegetation index (NDVI) differencing method and classification method are widely used as a change detection method and provides detailed information for detecting and monitoring changes in land use-land cover (LULC). So in the presented study to raise awareness for the LULC change in Ardakan, Iran, two Landsat ETM+ images of the years 1990 and 2006 have been prepared and...

Effect of different water depths on growth and yield of rice crop

This study was conducted to evaluate the effect of different water depths on the growth and yield of rice crop. Experiment was carried out in containers having an area of 0.64 m2 and the volume of 0.57 m3 at laboratory. Four water depths of 5, 10, 15 and 20 cm were taken in account; each water depth was replicated three times. This study was conducted in controlled condition to avoid the impact of rain. Result...

In vitro studies of biowastes on growth and sporulation of fungal bioagents

Biowastes of mango, carrot, papaya, banana, chukandar, pomegranate, orange, mosambi, chickpea and wheat were used to study the colony formation and sporulation of Trichoderma harzianum and Paecilomyces lilacinus. In the present study, it was observed that the initiation of colony formation of the fungal bioagents was recorded after 12 h only in biowaste of carrot, mango, chukandar, banana and papaya. In...

Analysis of pumpkin (Cucurbita pepo Linn.) biomass yield and its components as affected by nitrogen, phosphorus and potassium (NPK) fertilizer rates

Pumpkin (Cucurbita pepo L.) young leaves and vines are consumed as vegetables among the rural dwellers in Southwest Nigeria. It is a cheap source of protein, vitamins, fibres and antioxidants in their diet. Due to the intensive cultivation of available lands which affects the nutrient status of most soils and their productivity, the need to apply fertilizer on pumpkin became pertinent. Therefore, nitrogen,...
