Predicting Plant Height of Greenhouse Grown Crops with a Polynomial Growth Rate Model

Biometrical Journal, 1998
Summary: A prediction model for the growth of plant height is developed, using polynomials in time to describe the growth rate. The growth rate is affected by forcing factors through the polynomial coefficients. A random slope model is used to describe the difference in growth rate for plants grown under similar conditions. Maximum likelihood estimates

Tuber Crop Growth Model, Performance Rate, and Some Characterization Theorems

2018
Geometric and exponential distributions may be used for modeling number of tubers and yield of crop. Geometric distribution is discrete version of appropriate exponential distribution and both the distributions have memoryless property. We model a real dataset on number of potato tubers arising from a growth experiment conducted in Giridih farmland and

Rate of Uptake of Potassium by Three Crop Species in Relation to Growth

Journal of Experimental Botany, 1978
Barley, ryegrass, and fodder radish were grown in flowing nutrient solutions at four potassium concentrations, [K+], from 0-05 to 4 mg l-1. During the first 2 weeks after germination the response to [K+] (fodder radish > barley > ryegrass) depended on the potential relative growth rate, the ratio of root surface area to plant weight, and on the K+ flux

A Comparison of Population Growth Rate and the Rate of Increase in Food Crop Production in Africa

2020
Millions of people in Africa require sufficient food for healthy living. However, inefficient farming practices are making a lot more people hungry and poor. Simultaneously, the population keeps on increasing. The legitimate question that this study seeks to address is how the production capacity can meet the needs of the increasing population in the ...

Apple diameter and fruit growth rate at tree crop loads

2018
Fruit thinning is indispensable practice in production of large sized and good quality apple fruits. Often problems are light and late thinning. Intensity and late thinning were evaluated in trail settled near Zadar, Croatia, on apple cv. ‘Cripps Pink’ grafted on M9 rootstock and cultivated at spindle-type system.
