यदि पुर्नजीवनको कुनै स्रोत छ भने त्यो बिउ नै हो । जीवनको सुरुवात त यहीदेखि हुन्छ चाहे त्यो वनस्पति जगत् होस वा प्राणि जगत् । म एक कृषि विज्ञानको विद्यार्थी भएको हुनाले मैले यस लेखमा बिउलाई लिएर खाद्य–सुरक्षासम्बन्धि केहि भ्रमहरुलाई उद्घोष गर्ने प्रयास गरेको छु।केहि सन्देहहरुलाइ पनि प्रष्ट पार्ने जमर्को गरेको छु। कक्षा कोठामा गुन्जिने […]

बीउ कुनै पनि बालीको जग हो। कृषि बनस्पतिक परिभाषामा बीउलाई परिपक्क बीज अण्ड भनिन्छ। सरलीकृत तथा उदार अर्थमा धेरैले बीउलाई विरुवाको सन्तान उत्पत्तिको साधन भन्छन् । तसर्थ बीउ एक जीवित बस्तु हो र नयाँ बोट उत्पादन गर्न सक्षम हुन्छ । बीज एउटा सानो भ्रुणात्मक बोट हो जसलाई बीज कोटले छोपेको हुन्छ। बीज र अन्न बिचको […]
बीउ भनेको सुरक्षात्मक आवरणले ढाकेको एउटा परिपक्क रजकण र वानस्पातिक तरिकाले पुनरोउत्पादन गरि बाली उत्पादनका लागि रोप्न वा छर्न प्रयोग गरिने सजिव वस्तु हो । सामान्यतयास् बीउलाई बिरुवा विकासको पहिलो खुड्किलो रुपमा लिने गरिन्छ । माटोसङ्ग पारस्परिक सम्बन्ध गाँसेर सोही माटोमा उपलब्ध हुने विभिन्न प्रकारका आधारभुत तत्वहरुलाई प्रयोग गरेर बीउले अंकुरण थाल्दछ । र बिस्तारै […]
वानस्पतिक हिसाबले परिभाषित गर्दा बीउलाई एउटा परिपक्व अण्ड भनिन्छ । बीउ एक आफ्नो जातीय (वंशानुगत) अस्तित्व कायम राख्ने तथा आफ्नो जीवन संरक्षण गर्ने साधन हो । धेरैले बीउलाई विरुवाको सन्तान उत्पतिको साधन हो भन्दै परिभाषित गरेका छन् । बीउ जीवित हो त्यसैले रोप्दा उम्रने हुनु पर्दछ । सबै बीउ अन्न/दाना हुन सक्छ तर सबै अन्न […]
