Effect of Optimum Levels of Fertilizer on Growth, Yield and Quality of Chilli (Capsicum annuum L.) cv Pant C 1

Abstract

A field study was conducted in the Village Sabli of district Tehri Garhwal to know the effect of optimum levels of fertilizer on growth, yield and quality of Chilli (Capsicum annuum L.) cv Pant C 1. To assess the effect of fertilizers on yield and yield parameters randomize block design (RBD) in field and completely randomized design (CRBD) in laboratory were used with 20 treatment combinations. In this study two levels of nitrogen (40 and 80 kg N ha-1), one level of phosphorus (35 kg P2O5 ha-1), two levels of potassium (35 and 60 kg K2O ha-1) and two levels of farmyard manure (20 and 25 tonns ha-1) were taken. Among all treatment combinations, fertilizer dose of NPK and farmyard manure 80:35:35 kg and 25 t ha-1 (T9 treatment) was found most suitable for cultivation of chilli. A significant increase in yield and yield parameters were recorded like number of fruits plant-1, length of the fruit, 100 fruit weight, fruit yield kg plot-1, fruit yield q ha-1 and dry fruit yield q ha-1. The result found promising when 80 kg nitrogen, 35 kg phosphorus, 35 kg potassium and 25 tonns farmyard manure ha-1 respectively were used and was found significantly superior over other treatments. A significant effect of treatment on mean daily germination, highest value of relative growth index was recorded for T9 treatment. The T7 treatment had registered maximum mean germination time. The various treatments had significant effect on T50 and highest T50 value was observed in T7 treatment. On the basis of above study it can be suggested that fertilizer ratio of N:P:K (80:35:35) with 25 t ha-1 of FYM give good yield and plant growth.
