Abstract:

A field trial was conducted during kharif seasons of 2014 and 2015 on loamy sand, at the Agriculture Research Station, Anand Agricultural University, Jabugam, Gujarat (India), to assess the available nutrient status after harvest of rice soil as influenced by different levels of silicon and nitrogen application under loamy sand. The experiment encompassed four levels of nitrogen viz., 0, 75, 100 and 125 kg N ha-1 from ammonium sulphate and four levels of silicon viz., 0, 200, 400 and 600 kg Si ha-1 from calcium silicate. The experiment was laid out in randomized block design (Factorial) with three replications. Results revealed that individual application of nitrogen @ 125 kg ha-1 and Si @ 600 kg ha-1 produced the highest grain and straw yields of rice. The salt content, pH and organic carbon content of soil remained almost unchanged due to N and/ or Si applications. The available N content in soil was found to increase with graded levels of N and Si application. Similarly, available Si content in soil was also increased due to Si as well as N application. Application of 600 kg Si ha-1 significantly increased the P, K and S contents in soil after harvest of rice. The effect of N on available K2O content in soil after harvest of the crop was significantly increased.
