ABSTRACT
The present investigation was carried out during the 2017-2018, the wetlands of selected farmer's field in Chenkal panchayat of Parassala block, Thiruvananthapuram, Kerala, to assess the available nutrient status of rice soil in Southern laterites (AEU 8) and to develop Zn-B mix for rice. The overall fertility status of this region indicated that the soil was strongly acidic, high in organic carbon, available nitrogen and phosphorus and medium in potassium. Excess levels of phosphorus and wide spread of deficiencies of calcium, magnesium, sulphur, zinc and boron are the major limitations to crop production in this region. Zn and B requirement of rice (variety Uma) was worked out based on the available nutrient status of the soil and crop requirement. Based on this the Zn – B mix was prepared mixing ZnSO4 7H2O and H3BO3 in the ratio 4:1.
Key words :
Nutrient status, Rice, Zn-B mix.
