Abstract
A research study entitled "Soil nutrient dynamics under varying moisture regimes in banana" was conducted at Agronomic Research Station, Kerala Agricultural University, Chalakudy during the period of 2016-2018 with the objective of studying the optimum nutrient requirement under different irrigation levels of banana variety Nendran.The experiment was laid out in factorial RBD with two levels of irrigation and six levels of fertilizer treatments. The irrigation methods used were basin irrigation at 100 per cent pan evaporation (PE)(I1) and drip irrigation at 75per cent PE at two days interval (I2). The fertilizer treatments were 100 per cent recommended dose of NPK 190:115:300g/plant (KAU, 2016) (T1), 100:100:125 per cent NPK (T2), 100:75:100 per cent NPK (T3), 100:75:125 per cent NPK (T4), 100:50:100 per cent NPK (T5), 100:50:125 per cent NPK (T6). Observations were taken on different parameters for three years and pooled analysis of data had shown that application of P at 75 per cent and K at 125 per cent (T4) of recommended dose of fertilizer gave significantly higher yield. Between the irrigation treatments, basin irrigation (100% PE) resulted in significantly higher yield than drip irrigation. Drip irrigation at 75 per cent PE could save irrigation water and recorded significantly higher water productivity. Considering the economics of cultivation and B:C ratio, the treatment with P at 75 per cent and K at 125 per cent NPK recorded significantly higher value than all other treatments whereas the individual effect of irrigation treatments and interaction effect of irrigation and fertilizer treatments were statistically on par.
