Preface

  • India has 15% of the world's livestock on only 2% of the land, placing immense pressure on resources.
  • Cultivated fodder area has remained static at approximately 8.4 million hectares for two decades.
  • Improved techniques are necessary to catalyze vertical increases in fodder production.
  • The country faces a substantial deficit in green fodder (61.1%), dry crop residues (21.9%), and feeds (64%).
  • Education on production packages for forage crops is essential for improving yields and soil fertility.
  • The bulletin contains details on annual and perennial forage crops suitable for diverse agro-climatic conditions.
  • Each crop is covered with details on sowing techniques, varieties, nutrient management, and harvesting techniques.

Introduction

  • Despite the static area under cultivated fodder (8.4 million hectares), demand grows due to a rising livestock population.
  • The gap between demand and supply for green fodder is significant and anticipated to worsen.
  • Green fodders enhance livestock profitability, emphasizing the need for quality fodder.
  • Availability of diverse forage species allows for various management strategies to maximize productivity.
  • The guide focuses on Kharif and Rabi season crops to meet the overall needs for livestock production.
