Abstract
An experiment conducted at Instructional Farm Polyhouse, Department of Soil Science, Dr. Sharadchandra Pawar College of Agriculture, Baramati. The experiment was laid out in Randomized Block Design (RBD) with four replications. The treatments were five, viz., T1- Control, T2- Recommended dose of fertilizer, T3- Recommended dose of nitrogen and phosphorus (RDNP) + 125% Recommended dose of potassium (RDK), T4- Recommended dose of nitrogen and phosphorus (RDNP) + 150% Recommended dose of potassium (RDK) and T5- Recommended dose of nitrogen and phosphorus (RDNP) + 175% Recommended dose of potassium (RDK). Data were taken on yield contributing characters and yield and the collected data were statistically analyzed for evaluation of the treatment effects. The yield contributing characters like fruit length (7.10 cm), fruit diameter (2.51 cm), no. of fruits per plant (28.19) and weight of fruit (20.56 gm) was obtained highest in treatment T5 i.e. RDNP + 175% RDK. The greatest fruit yield per hectare was obtained in T5 treatment (25.22 t/ha). The study revealed that, application of RDNP+ 175% RDK by fertigation from 10 DAT to 60 DAT was found to be optimum for growing of Jalapeno pepper in red bole soil under polyhouse condition.
