when we were discussing about the cardinal temperature the minimum temperature required for barley oats is around three degree centigrade so here the weather sensitivity suppose the temperature is one degree or zero degree the crop does not germinate so weather sensitiveness can be defined as under a prevailing weather condition the crop growth gets stopped or crops so sensitiveness to unfavorable weather that is very very important this may be for a crop entire crop apple tree cannot be grown in semi-arid climate one example so it is weather sensitive and also crop stages you take wheat crop it does require a cool temperature during its vegetative stage from germination if the temperature is more than 20 degree centigrade or 24 degree centigrade during daytime the vegetative stage gets affected and your yield also got affected so in the case of the wheat vegetative stage the rice is the flowering stage so for different crops different stages are there those stages are weather sensitive and the particular farm operations farm operations also weather sensitive so we were discussing about dryland agriculture in the absence of the rainfall can you go for sowing and dryland it is impossible but in irrigated condition you can take up sowing with groundwater support so this is weather sensitive farm operation under your dryland agriculture now weather sensitive crops now as he told you earlier the climate influence the distribution of crops over different regions of the world and hence the temperate crops are sensitive to weather that prevail in plain areas of the tropical climate understood we were discussing over and over on this subject example apple plum procoli of temperate climate have weather sensitive to tropical climate so weather sensitive see accordingly we have to prepare our agro adversaries based on the weather forecast that will be detailing very much during our later classes there are weather sensitive crop stages a particular stage of a crop is weather sensitive to weather that prevail during crop growing period for example cotton is being grown across the different countries when a bowl bursting is there it may occur under to 150 days if it rains it is highly weather sensitive so accordingly we have to develop our agro adversaries suppose if it is raining during bowl bursting up post phone you are picking go for next sunny day for harvesting like that you have to prepare weather sensitive stages higher maximum temperature during vegetable stage of a wheat crop I told earlier cloudiness that prevailed from flowering to mature stage in rice crop very very important from flowering to 15 days earlier to harvest there must be a sunny day they say that the radiation must be available to the rice crop to make the grains highly productive so you will be getting more yield if it is that otherwise your yield will be get affected then primordial initiation and over development and burden size net in coconut or sensitive to soil moisture availability soil moisture means again under dry land situation it is with rainfall or under irrigated condition with the ground water ground water is mainly controlled by your rainfall received in a particular climate whether it may be airy climate or semi airy climate or sub-hewed climate or humid climate or per humid climate then prevalence of low minimum temperature during pod permission stage of ground nut I have left it pod is there pod permission of stage of ground nut this I had a good experience with this crop when I was working with some Indian resistation I could see that there was no pod developed in ground nut across more than 10,000 hectares in a particular district the constant extension officer asked me what might be the reasons we were examining so many reasons we don't know what was happened here interestingly after review of literature I could see that the minimum temperature during pod development stage is very very low your pod may not develop then we examined our local records interestingly there was minimum temperature below 20 degree centigrade during about 22 30 days they had made the crop sterile so this pod formation stage is very sensitive to your temperature that is the information to be absorbed then weather sensitive form operations as I indicated earlier a particular form operation of a crop is weather sensitive to weather that prevailed during the crop stage this was discussing about dry land agriculture another one we have discussed already in detail then we were studying the wind windward direction and leeward direction windward direction means from area from that point wind comes leeward means wind goes if you make a plant production chemicals dusting or spraying against opposite to your windward direction means there is a drifting it may fall on the person who do the operation he gets poison number one number two there is input efficiency is getting reduced so these are all weather sensitive form operations and the prevalence of cyclonic wind and rainfall during harvesting of rice this is very important because in India about 43 million hectares we have a rise if a cyclone exist means we will be losing our production very greatly and there is a crippling problem for our food availability and food demand now these are very very important so as I told earlier crop production risk must be considered before developing aggro advisories weather sensitive crops weather sensitive stages weather sensitive form operations have to be considered meticulously for developing a hundred percent effective aggro advisories thank you very much
