abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
the drought continuity and also restricting watery sources caused agriculture section forgetold flooding methods for optimum water exploitation and proceeding new irrigation systems.new generation of irrigation systems called intelligent systems is a new solution leading toexploiting water increase to higher than 80%. in order to measure sensors and to controlprocessors in designing and dismoun...
in order to examine the hypothesis of this research, an accidental sample of 122 students have been appointed from among the community of female students who were studying at the last year of primary school in isfahan . the sample was divided into four groups, cognitive group, behavioral group, cognitive- behavioral group and control group. the impacts of independent variables have been assesse...
Cattle rearing generate more global warming green house gases than driving cars. These green house gases leads to changes in the climate. This climate change affects the livestock, man and natural environment continuously. For this reason it is important for livestock farmers to find the ways which minimize these gases emission. In this article the causes of climate change and effects, measures...
UNLABELLED We conducted several aviary experiments to investigate the influence of colours in quantity judgments of two species of birds; house crow (Corvus splendens) and common myna (Acridotheres tristis). Different quantity (in seven different food proportions) of mealworms were presented nonsequentially to all birds using artificially coloured red mealworms, for experiment 1, and using arti...
As it is well known, Monitoring and controlling of green house parameters plays a crucial role for quality production of crops. Different techniques have been developed in past for actual monitoring and controlling of major green house parameters such as temperature, humidity, soil moisture, light intensity and CO2 in atmosphere. Controlling of parameters is done by means of relays. The main ta...
This paper presents the novel control strategy, for green house climate control. Till now, there are many control strategy that is work in India, to control green house environment but they are not adequate for good control performance. The controller used in the present work is conventional proportional, integral and derivative (PID) controllers with adaptive neural network. It provides good a...
