1. फसल उत्पादन की एक विधि का वर्णन करो जिससे अधिक पैदावार प्राप्त हो सके|

उत्तर: फसल उत्पादन में अधिक पैदावार प्राप्त करने के लिए मिश्रित फसल तथा अंतराफसलीकरण दो उपायों का प्रयोग किया जा सकता है|


2. खेतों में खाद तथा उर्वरक का उपयोग क्यों करते हैं?

उत्तर: लगातार फसलों के उत्पादन से खेतो की उपजाऊ शक्ति में कमी आ जाती है| मिट्टी में पोषक तत्वों की कमी हो जाती हैं जिससे उत्पादन कम होने लगता है| खाद तथा उर्वरक का उपयोग मिट्टी की उपजाऊ शक्ति को बढ़ाने के लिए किया जाता है जिससे उत्पादन में वृद्धि की जा सके|


3. अंतराफसलीकरण तथा फसल चक्र के क्या लाभ है?

उत्तर: अंतरा फसली करण और फसल चक्र में फसल का चुनाव एक पैटर्न द्वारा किया जाता है जिससे मिट्टी में पोषक तत्वों की आवश्यकताएं भिन्न हो जाती हैं| इससे मिट्टी के पोस्टको का अधिकतम उपयोग किया जा सकता है और फसल में रोग फैलने से भी बचाया जाता है|


4. अनुवांशिक फेरबदल क्या है? कृषि प्रणालियों में यह कैसे उपयोगी है?

उत्तर: अनुवांशिक फेरबदल से अभिप्राय है कि ऐच्छिक गुणों को एक किस्म से दूसरे किस्म में डालकर एक संकर किस्म बनाना जिससे कि उसकी गुणवत्ता, रोग प्रतिरोधक क्षमता तथा उत्पादन क्षमता में वृद्धि हो|


5. भंडार ग्रह गोदामों में अनाज की हानि कैसे होती है?

उत्तर: भंडार ग्रहों में हानि जैविक कारक जैसे कि कवक, जीवाणु आदि से होती है तथा अजैविक कारक भंडारण के स्थान पर नमी की उपस्थिति तथा ताप की कमी के कारण होते हैं| 

यह कारक उत्पादक की गुणवत्ता को खराब कर देते हैं वजन कम कर देते हैं तथा अंकुरण करने की क्षमता को भी हानि पहुंचाते हैं जिस कारण से बाजार में उत्पाद की कीमत बहुत कम हो जाती है|


6. किसानों के लिए पशुपालन प्रणालियां कैसे लाभदायक हैं?

उत्तर: पशुपालन प्रणालियां निम्न प्रकार से किसानों के लिए लाभदायक हैं:

यह उत्पादन में होने वाले व्यय को कम करती है

  • किसान खेती के साथ-साथ दूध देने वाले पशुओं को पालकर अतिरिक्त आय कमा सकता है|

  • पशुपालन के अंतर्गत जानवरों द्वारा खाद बनाने में सहायता मिलती है|

  • बेहतर नस्लों के पशुपालन से दूध भी बेहतर मात्रा में प्राप्त होता है|

  • बहुत से पशुओं का इस्तेमाल बोझा ढोने तथा कृषि के अन्य कामों के लिए भी किया जा सकता है|


8. उत्पादन बढ़ाने के लिए कुकुट पालन  तथा मधुमक्खी पालन में क्या समानताएं हैं?

उत्तर: 

  • उन्नत किस्मों का चुनाव करना |

  • रोग प्रतिरोधक क्षमता अधिक होनी चाहिए|

  • सर्वश्रेष्ठ नस्लों का उपयोग करना ताकि उत्पादन अधिक हो|

उत्तर:

  • प्रग्रहण मत्स्य- इसके अंतर्गत प्राकृतिक स्रोतों जैसे नदी झील आदि से मछली पकड़ना सम्मिलित हैं|

  • मैरीकल्चर- आर्थिक महत्व वाली मछलियां, समुद्री जीवो और समुद्री खरपतवार का समुद्री जल में संवर्धन मैरीकल्चर कहलाता है|
