Weeds control in main kharif crops भारत की कृषि-अर्थव्यवस्था विभिन्न फसलों के उत्पादन एवं उत्पादकता पर निर्भर करती हैं। कीटों, बिमारियों तथा खरपतवारों के प्रकोप से फसलों के उत्पादन में होने वाली क्षति को बचाकर खाद्यान्नों का उत्पादन अधिक बढ़ाया जा सकता है। फसलों में सर्वाधिक हानि खरपतवारों से होती हैं। खरपतवार (weeds) अवांछित पौधे होते है जिनकी एक निष्चित स्थान व समय पर आवश्‍यकता नहीं होती है और बिना बोए अपने आप उग जाते हैं। इसके कारण खरपतवारों व फसलों के बीच पौषक तत्वों, जल, स्थान, प्रकाश आदि के लिए प्रतिस्पर्धा बढ़ जाती हैं। विभिन्न फसलों की उपज में केवल खरपतवारों के कारण होने वाली क्षति 15-70 प्रतिशत तक हैं।...

A simple way to determine maturity is to slice the tomato with a sharp knife. If seeds are cut, the fruit...

चारा बीट - एक उत्कृष्ट चारा फसल Fodder beet (Beta vulgaris sub sp. maritime) is considered to be one of the highest biomass producing crop and cultivated globally mainly for its fleshy, swollen roots. The major fodder beet producing countries are France, United Kingdom, Netherland, New Zealand, Belarus, China, Japan. The plant is similar to sugar beet but its roots are less deeply buried (upto 2/3 above ground) and the dark green heart shaped leaves are borne in a rosette lying more horizontally (Fig.1). It has an inherent capacity of salt tolerance and probably the highest biomass producing crop in saline environments. Fodder beets provide excellent quality fodder (Table 1). It is...

भारत की मृदा व फसलों में बोरोन तथा मोलिब्डेनम की कमी और उर्वरकों के प्रयोग सेे उनमे सुुुुधार   Plants require eight micronutrients for their growth and development. Out of them, Boron (B) and Molybdenum (Mo) are anionic micronutrients found to be deficient in Indian soils and crops. The essentiality of the B and Mo for higher plants was first established by K. Warington in 1923 and by D. I. Arnon and P. R. Stout in 1939 respectively. The information regarding deficiency of B and Mo in soils in India, their role in plant growth and deficiency symptoms and fertilizers containing B and Mo for amelioration is being provided for the benefit...

शुष्‍क क्षेत्र में उच्च आय, सुरक्षा और उपयुक्‍त संसाधन उपयोग के लिए एकीकृत खेती प्रणाली The Indian hot arid zone occupies over 31.7 m ha area of which 81.0% lies in two states i.e.  Rajasthan and Gujarat. The characteristic features of this region are low and erratic rainfall (100 -420 mm/year), extreme temperatures (-5.7 to 50.0°C), long sunshine duration (6.6-10 hours), low relative humidity (30%-80%) high wind velocity (9-13 kmph) and high evapotranspiration (1500-2000 mm). The soils are poor in nutrients, wind erosion occurs on a mammoth scale and paucity of water is a perennial bottleneck. Dry land farming in farming system mode is the main occupation of the people . The crop...
