Abstract

A research study entitled “Soil nutrient dynamics under varying moisture regimes in banana” was conductedat Agronomic Research Station, Kerala Agricultural University, Chalakudy during the period of 2016-2018with the objective of studying the optimum nutrient requirement under different irrigation levels of bananavariety Nendran.The experiment was laid out in factorial RBD with two levels of irrigation and six levels offertilizer 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 percent 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), 100:50:125per cent NPK (T6). Observations were taken on different parameters for three years and pooled analysis ofdata had shown that application of P at 75 per cent and K at 125 per cent (T4) of recommended dose offertilizer 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 irrigationwater and recorded significantly higher water productivity. Considering the economics of cultivation andB:C ratio, the treatment with P at 75 per cent and K at 125 per cent NPK recorded significantly higher valuethan all other treatments whereas the individual effect of irrigation treatments and interaction effect ofirrigation and fertilizer treatments were statistically on par.
