Not AvailableProfessor Calyampudi Radhakrishna Rao has completed 100 years of his active life on September 10, 2020 which included 8 decades of his professional life in Statistical Sciences. Lot of academic programmes have been organized throughout the Globe to felicitate Professor Rao and his unparalleled contributions in theory and application of Statistical sciences. Professor C.R. Rao has left an indelible stamp in almost all areas of statistics. It is scarcely possible to describe the contours of Professor C.R. Rao''s research output. In this article, we shall present a brief biographical sketch of the living legend Professor C.R. Rao and shall also make a valiant attempt to highlight briefly few prominent results from Professor C.R. Rao’s Library of achievements in the area of Design of Experiments with special reference to agricultural sciences.Not Availabl

Not AvailableIn Balanced Sampling Plans Excluding Adjacent Units (BSA plans) first order inclusion probabilities are equal and second order inclusion probabilities are zero for pairs of units at a distance less than or equal to m and are constant for pairs of units which are at a distance greater than m. These plans are useful when the adjacent units in the population provide similar information. In this paper, an algorithm based on linear programming approach has been developed for construction of two-dimensional BSA plans under sharing a border and island adjacency schemes for m <= 2. Some results on existence of such BSA plans have also been obtained for each adjacency scheme separately.Not Availabl

Evaluation of STCR Based Targeted Yield Equations of Amaranthus (Amaranthus tricolor L.) in Southern Laterite Soils (AEU-8) of Kerala

A field experiment was carried out in the Instructional farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, Vellayani, Thiruvananthapuram which comes under agro-ecological unit AEU-8 from the period March 2022 to June 2022 to test and validate the targeted yield equation for nutrient management developed by All India Coordinated research project on soil test based crop response studies (AICRP on STCR) 2014 for the cultivation of Amaranthus. The experiment was laid out in randomized block design with four replications and five treatment combinations viz., T1 as KAU organic POP, T2 as soil test-based KAU, T3, T4, T5 as STCR based targeted yield recommendation for a target yield of 20, 22.5 and 30&nbsp; tonnes respectively. Nutrient management with the application of STCR based targeted yield recommendation for a target yield of 25 tonnes T5 showed a significant increase in plant height, stem girth, leaf length, petiole length, leaf width, number of branches plant-1, number of leaves plant-1 and root length at 30 and 60 DAS respectively. The treatment, T5 also improved the N, P and K content and their uptake by leaf, shoot and root respectively of Amaranthus and gave significantly better results for all parameters in comparison to other treatments. The equation of&nbsp; AICRP on STCR 2014 for the nutrient management for the cultivation of Amaranthus can be extended to the ultisols of AEU-8 of Thiruvananthapuram district of Kerala

Assessment of Nutrient Status in the Cassava Growing Tracts of Southern Laterites (Agro Ecological Unit 8), Kerala, India

As part of the study, a survey was conducted to identify the soil fertility constraints of cassava growing tracts of AEU 8, Thiruvananthapuram, which is one of the major cassava growing regions of the State of Kerala in peninsular India. The method of sampling of the survey was random sampling wherein a random sample of size one was taken from each of 50 ha cassava area. Panchayat wise soil samples were collected (77 samples) by geo referenced soil sampling method from major cassava growing areas of the unit. The samples are analyzed for the soil fertility parameters following standard analytical procedures. Results indicated that the soil was very strongly acidic to strongly acidic, normal electrical conductivity, medium organic carbon, medium nitrogen and potassium, high phosphorus, sufficient calcium, sulphur, zinc and copper, deficient magnesium and boron
