Mathematical modelling of microwave drying of safou pulp

Microwave drying characteristics of safou pulp (Dacryodesedulis) were evaluated in a laboratory scale microwave dryer. The drying experiments were carried out at 0.42, 0.56 and 0.70 kW. Three commonly used mathematical models were evaluated with the experimental data. The results indicated that the Page model was most adequate in predicting moisture transfer for safou pulp, just a falling rate period was observed in the...

Assesment of soil fertilty at different working depths of moldboard plow under silty loam soil

A field experiment was conducted to determine the soil fertility influenced by moldboard plow.The composite soil samples were drawn from the depths of 0 to 5, 5 to 10, 10 to 15, 15 to 20 and 20 to 25 cm respectively, in order to ascertain the physiochemical properties of soil. Results obtained from the present experiment are summarized as; the total soluble salts in the experimental area showed that the soil was...

Studies on the standardization of ripening techniques for oranges

Fruits of oranges cultivar’ free from any external and internal disorders harvested at physiological green mature stage were utilized for studying its ripening behavior. Initially, fruits were treated with Neem oil (1%). in order to break any pest attack and the treatments were given as foliar spray. Freshly harvested fruit were divided into different lots. The first lot of fruit was treated with ethylene gas as...
