Thesis Title: “Effect of Nitrogen management in pigeon pea”.
A field experiment was conducted during kharif season 2018 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to evaluate the effect of nitrogen management in pigeon pea. The area situated at a latitude of 29o 40′ North and longitude of 77o 42′ East with an elevation of 237 m above mean sea level. The soil of the experimental field was well drained, sandy loam in texture, low in available nitrogen, medium in available phosphorus and potassium. Ten treatments consisting application of different level of nitrogen and vermicompost were tested in randomized block design with three replications. The data on growth, yield and its contributing traits content and uptake of nutrients at various stages along with available N, P, K in soil were estimated as per the standard procedure.
The experimental results revealed that growth attributes (plant height, number of branches, dry matter accumulation plant-1, number of nodules plant-1, nodules dry weight), yield attributing traits (Number of pods plant-1, number of grain pod-1, pod weight plant-1, grain yield plant-1, test weight), biological yield, grain yield, straw yield and uptake of nitrogen, phosphorus and potassium, iron , zinc , boron in pigeon pea differ significantly among different treatments. Growth parameters were comparatively better in the treatments where 40 N in two split was applied. The highest grain yield and harvest index recorded in T7 was found statistically at similar to the treatments T6, T9, T10 and significantly higher than the rest of the treatments. The application of N, P over control resulted approximately 25 percent improvement in grain yield. Available nutrient in soil after harvest of pigeon pea were variable under different treatments. Treatments receiving higher level of N application as well as additional application of vermicompost over recommended N, P showed higher N availability. From the study it can be concluded that higher rate of N application than the recommended N dose in pigeon pea seems better in the soils deficient in available N. Integrated nutrient management can also improve the pigeon pea yield.
