Abstract

Abstract: Tomato is an important vegetable crop which provides approximately 40% of the daily recommended vitamin C and vitamin A, which supports human health. The experiments were laid out in a Completely Randomized Design (CRD) having four treatments and four time repetition under high tunnel. Nitrogen (N), phosphorus (P) and potassium (K) fertilizers were applied at the rate of 60:60:60 kg/ha or 1:1:1 to T1, T2 and T3 after each 10, 20 and 30 day's interval while Zn (5 kg/ha) was applied as a basal dose. The highest marketable yield was observed for T2 after each 20 days of NPK application. Maximum Grad-A fruit among the treatments was recorded for T1, Grade-B for T2 & T3 and Grade-C for T0 . Highest density was recorded for T2, % moisture for T0, maximum chlorophyll content in leaves was recorded for T2 while highest shelf life was noted for T1, T2 and T3 except T0 . The fruit and straw of tomato was analyzed to determine N, P and K (%) by using standard protocol. Among all the treatments highest N, P and K in fruit was observed for T1 . In case of straw maximum N was observed for T1 whereas high level of P and K was recorded for T2 . Similarly the total NPK uptake were in the order as: T1 > T2 > T3 >T0, respectively. Experiential findings revealed that application of NPK after each 20 days are the suitable interval to get high marketable yield and highly bio-fortified and quality tomato crop.
