Abstract

Objectives: To check the effect of various methods used for seedbed preparation namely manually prepared seedbed and seedbed prepared by using rotavator, also for the use of organic fertilizer and chemical fertilizers on Pigeon Pea crop production. Method/Approach: In this experiment the entire 9 acre land is divided into 18 equal plots. The combination of seedbed preparation and fertilizers are finalised in 9 different categories. Two plots were selected randomly for each combination of seedbed preparation and fertilizer for the experiment, and the final product is combined to measure the total output and to compare which is the best combination. The chemical fertilizer used is divided into three categories according to their proportion one is as per the guidelines of Ministry of Agriculture, central government, India; i.e. 50kg per acre, other quantity is much lesser than the guidelines i.e. 35kg per acre and last one is according to actual farmers practice in the region i.e. 65kg per acre. The quantity of organic fertilizer used is 45kg per acre and 60kg per acre for both seedbed preparations were done by manually and by using rotavator. Findings/Observations: The maximum production of Pigeon Pea of 814kg was obtained from plot whose seedbed is prepared by using rotavator and organic fertilizer followed by 802 kg from the plot whose seedbed is prepared by using rotavator and chemical fertilizer was used. The minimum Pigeon Pea production of 690kg was obtained from the plot whose seedbed was prepared manually and chemical fertilizer was used. Applications/ Improvements: Use of rotavator for seedbed preparation for sowing and organic fertilizers can be used for every conventional as well as cash crop. Seedbed preparation by using rotavator gives better pulverisation which affects in higher crops productivity also organic fertilizers eliminates the chances of soil and water pollution which results in achieving higher benefit to cost ratio for farmers.
