Abstract:
A field experiment was conducted at research farm of Lovely Professional University during rabi season of 2017-18 and 2018-19 on variety HD 2967 of wheat. The experiment was laid out in RBD (Randomized Block Design) with nine treatments and three replications which involved treatments with different nitrogen doses. The crop was sown by two different methods viz. flatbed method (conventional method) and raised bed method. The experimental results was showed that raised bed planted wheat with the application of 100% NPK improved the growth and grain yield through yield contributing characters like plant height (cm), number of tillers per plant, LAI, length of spike was observed highest in treatment 100% NPK (T6) on raised bed planted wheat for both the years. Similar trend was observed in case of number of grains per spike in (T6) treatment applied with 100% NPK on raised bed. 100 grain weight (g) was highest for treatment applied with 110% N with RDF of PK during both years of study. At the time of harvest according to the year 2017-18 maximum plant height was recorded in the treatment in T4 (102.3 cm). Although in the year 2018-19 the maximum result revealed for plant height was in treatment T6 (107.8 cm). According to year (2017-18 & 2018-19) the number of tillers at harvest stage was recorded significantly highest for T6 followed by T7 and T2 which are at par statistically. According to the year 2017-18 the results showed that number of leaves (2017-18) reported maximum (5) in T1 (RDF PK +75%N) followed by other treatments. Similarly in the year 2018-19 the maximum number of leaves was found in T6 (5) for treatment (T6) applied with 100% NPK on raised bed followed by T7, T1 (4). The results showed that leaf area index (2017-18) reported maximum (4.4) in T8 (RDF PK +130%N) followed by other treatments. Similarly in the year 2018-19 the maximum leaf area index was found in T6 (4.2) for treatment (T6) applied with 100% NPK on raised bed. Length of spike was noticed highest (11.8 cm) in T8 under condition with 30% higher N than recommended dose. It was also at par with T5, T6 and T7. During 2018-19 length of spike found highest (11.6 cm) in T6 under recommended dose of fertilizer on raised bed.
