Trimble Agriculture’s GreenSeeker® handheld crop sensor, available across India, is an easy-to-use handheld measurement device designed to assess the health of a crop. Readings taken with the device can be used to make objective decisions regarding the amount of fertilizer to be applied to a crop, resulting in a more efficient use of inputs. Farmers or any other operator just need to position the handheld sensor over a plant, pull the trigger, and the GreenSeeker handheld instantly calculates the Normalized Difference Vegetation Index (NDVI), which represents the health of the plant. By gathering several readings from plants throughout a field, farmers can better determine the overall health and needs of a crop. This can result in a more efficient use of fertilizer, which benefits both the farmer's bottom line and the environment. Rajan Aiyer, MD, India and SAARC region for Trimble said, “GreenSeeker Handheld is a powerful yet affordable device that can help boost crop yields for Indian farmers while still reducing their overall fertilizer usage. As the global leader in Precision Agriculture technologies; we are thrilled to bring GreenSeeker to India; for we believe technology can play a key role in boosting India’s agriculture productivity and farmers’ incomes.” The GreenSeeker handheld provides farmers, agriculture researchers and scientists with an affordable way to...

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 of the stakeholders. Role of Boron and Molybdenum in plant growth and their deficiency symptoms Normal boron sufficient plants are having B content ranging from 10 to 200 mg/kg. Boron is neither a constituent of enzymes nor it activates any of the enzymes. Most important property of B is to form stable complexes with organic compounds. It is responsible for the cell wall formation and stabilization, lignification and xylem differentiation. It imparts drought tolerance to the crops. It plays a role in pollen germination and pollen tube growth. It facilitates ion uptake by way of increasing the activities of plasma membrane bound H+-ATPase....
