Improved cultivation of Taramira Rapeseed, brown mustard, yellow mustard and raya are included in the group of Taramira crops. Taramira can be grown in both fertile and barren lands with limited irrigation and rainfed areas. It is mostly cultivated in rainfed areas in places where other crops cannot be grown successfully. The amount of oil in it is found to be around 35 to 37 percent. Improved cultivation of Taramira तारामीरा फसलों के समूह में तोरिया, भूरी सरसों, पीली सरसों तथा राया आते है। तारामीरा को उपजाऊ एवं बंजर भूमि में सिमित सिंचाई व बारानी दोनों क्षेत्रों में उगाया जा सकता है। इसकी खेती अधिकांशतः बारानी क्षेत्रों में ऐसे स्थानों में की जाती है जहाँ अन्य फसल सफलतापूर्वक पैदा नहीं की जा सकती है। इसमें तेल की मात्रा लगभग 35 से 37 प्रतिशत पायी जाती है।  जलवायु- तारामीरा को ठन्डे शुष्क मौसम और चमकीली धूप की आवश्यकता होती है। अधिक वर्षा वाले स्थान इसकी खेती के लिए उपयुक्त नहीं है, अधिक तेल उत्पादन के लिए इसको ठंडा तापक्रम साफ खुला मौसम और पर्याप्त मृदा नमी की आवश्यकता पड़ती है। फूल आने और बीज पड़ने के समय बादल और कोहरे भरे मौसम से तारामीरा की फसल पर हानिकारक प्रभाव पड़ता है। इस मौसम में कीटों और बीमारियों का प्रकोप अधिक होता है।   भूमि का चुनाव- तारामीरा के...

सरसों (रेपसीड) की संकर बीज उत्पादन करने की तकनीक The potential of the conventionally bred open pollinated varieties has been exploited to its maximum level resulting in a platue in the productivity level, which breeder often calls as yield stagnancy. Here we need to exploit the heterosis i.e. hybrid vigour to break the yield platue. Three hybids, namely NRCHB 101, NRCHB 506 and Dhara mustard hybrid-1 were released in 2008. Development of a successful hybrid seed production technology in a crop is essential for the extension of hybrid technology to farmers. Standardization of sowing time and planting ratio is an important aspect for economic hybrid seed production and it is more valid for a species, which is predominantly self- pollinated. A higher frequency of male rows in a planting ratio sown at optimum time gives higher hybrid seed set in Indian mustard.               HSP plot with 8:2 row ratio           Hybrid seed production block A successful hybrid seed production technology depends mainly on maintenance of its parental lines at highest purity. Maintenance of parental lines/nucleus seed production CMS is sown in seed multiplication plot along with its maintainer (B-line) in 4: 2 ratio just like hybrid seed production plot. In order to have high pollen pressure, planting...

सरसों - रेपसीड में एकीकृत कीट प्रबंधन  Rapeseed and mustard are most important rabi oilseed crops of our country. This group of crops comprises toria, brown sarson, yellow sarson, gobhi sarson, raya or Indian mustard, black mustard, rai and taramira. India is the second largest producer of rapeseed-mustard in the world after China. Major bottleneck in its production is reduction of yield due to pest attacks. Insects and diseases are appears important limiting factors which restrict the fast expansion of cultivation and productivity of these crops. One of the major concerns in enhancing and stabilizing the yield of rapeseed mustard is the incidence of insect and diseases, which are causing the damage to crop at different stages and responsible for huge yield losses to a extent ranging from 10 to 90 per cent. In present article important pests of mustard and their integrated management has been described in detail. A. Major Diseases of  mustard i. White rust (Albugo candida): It is a serious problem of mustard causes leaf phase (local) and stag head (systemic) infections. The symptom develops on all aerial parts except root as light brown water soaked lesion covered with white growth of mycelium. Prominent white or creamy yellow pustules appear on lower surface of leaves and clearly visible during February -...
