Abstract
Field experiment was conducted in the Farmers field (Sandy clay loam –Typic Ustifluvents) at kuttalam to study the effect of nitrogen and boron on growth and yield in rice. The treatments consisted of Factor A- Nitrogen levels, 0, 75, 150, 225 kg ha-1 and Factor B- Boron levels 0, 1.5, 3.0 kg ha-1.Totally fifteen treatments were conducted in a FRBD design with three replications. The test crop was rice with variety ADT 46. The results demonstrated that that application of nitrogen or boron alone or both significantly increased the growth and yield in rice. Application of nitrogen and boron recorded highest growth and yield than in individual application. The highest growth parameters viz., plant height (111.8cm), no. of tillers/hill (22.6), LAI (4.8), chlorophyll content (46.3 SPAD value) were recorded in N3B1 (225 kg N ha-1 and 1.5 kg B ha-1) in rice. With Respect to nitrogen alone, the highest plant height (106.5cm), no. of tillers/hill (20.1), LAI (4.6), chlorophyll content (43.7 SPAD value) were observed in N3 (225 kg ha-1). Further More, the results suggested that with regards to boron alone, the highest plant height (91.7cm), no. of tillers/hill (15.6), LAI (4.0), chlorophyll content(36.3 SPAD value) were registered in B1(1.5kg ha-1). The highest grain and straw yield (5631.3, 7637.1 kg ha-1) were recorded in N3B1. Among the nitrogen treatments, the highest grain (5344.3 kg ha-1) and straw yield were recorded in N3. With regards to B alone, the highest grain (4695 kg ha-1) and straw yield (6509 kg ha-1) were recorded in B1. This study concluded that for attaining maximum yield in nutrients deficient soil (N and B), application of 225 kg N ha-1 and 1.5 kg B ha-1 found to be beneficial to the farmers.
