Item Response of rice to application of micronutrients(Department of Soil Science and Agricultural Chemistry, College of Horticulture, Vellanikkara, 1992) Muralidharan, P; Jose, A IA field experiment was conducted to study the response of rice to application of secondary and micronutrients during the first and second crop seasons of 1991. The experiment was conducted at the agricultural Research Station, Mannuthy using rice variety Jyothi and the soil was sandy clay loam in texture. The treatments consisted of the different micronutrients (Zn, Cu, Mn, B and Mo), magnesium, sulphur, a combination of the above said nutrients and stanes Microfood, a micronutrient formulation, in addition to the control with no micronutrients. Application of N, P and K was done uniformly in all the treatments. Soil and plant samples were collected at the maximum tillering, flowering and harvesting stages of the crop for the determination of uptake and availability of nutrients, pH and specific conductance. The continued effect of the application of micronutrient was studied by repeating the experiment in the second crop season with the same set of treatments applied to the same plots. Observations on the morphological and yield characters and yields of grain and straw were recorded in both the seasons of crop growth.Item Studies on a manure supplement containing secondary and trace elements prepared from sea water (Sagar) on the growth, yield, quality and absorption of nutrients by rice(Division of Agricultural Chemistry, College of Agriculture, Vellayani, 1975) Chinnamma, N P; Money, N SA field experiment was conducted to assess the effect of application of Sagar, a manure supplement prepared from the sea water on the growth, yield and quality of rice and absorption of nutrients from soil. The result obtained are summarised below. 1) Application of NPK increased significantly all the growth characters and these characters were increased steadily with increase in the levels of NPK. Sagar application increased considerably the number of tillers and the number of productive tillers per plant.Item Response of bhindi (abelmoschus esculentus L. moench) to fertigation and foliar nutrition in red loam soil of Kasaragod(Department of Soil Science and Agricultural Chemistry, College of Agriculture, Padannakkad, 2018) Ashwini, B N; Binitha, N KItem Flux and dynamics of iron and aluminium in wetlands of Kuttanad and its management for rice (Oryza sativa L.)(Department of Soil Science and Agricultural Chemistry, College of Agriculture, Padannakkad, 2017) Ebimol, N L; Suresh, P RItem Silicon, boron and zinc nutrition of bitter gourd (Momordica charantia L.) var. preethi(Department of plant soil science and agricultural chemistry, Padannakkad, 2015) Mohammed, Shahid Salam C H; Suresh, P R
