Background: In India, agriculture and animal husbandry are inextricably linked and are essential for livelihood security. Despite the fact that India has the world’s largest livestock population, feed and fodder supply is under huge strain, especially as area accessible for fodder cultivation has been shrinking. During the months of March-May and November-February are known as lean periods of fodder production, the supply of green fodder is limited throughout the year in a rainfed condition. Fodder crops develop swiftly and cover the ground surface quickly, even in low-rainfall conditions, producing a significant amount of green fodder while also providing vegetative cover over the land, resulting in resource conserving as well as increased productivity. In this context, the current study was conducted to evaluate various fodder crops, assess their productivity and quality and make appropriate recommendations for semi-arid tropics of India.
Methods: Field experiments were carried out for three years from 2015-16 to 2017-18 at the Agricultural Research Station, Ananthapuramu andhra Pradesh, India, which is located between 14°41'N Latitude and 77°40'E Longitude and an altitude of 350 m. above mean sea level, which falls under the Semi-Arid Tropics. The experiment was laid out in a randomized block design with nine treatments (fodder crops) and three replications. The treatments comprised of different fodder crops viz., fodder sorghum, fodder maize, fodder bajra, clusterbean, fodder cowpea, field bean, brown top millet, horse gram and sunhemp.
Result: The current study concludes that fodder bajra, fodder sorghum and fodder maize are potential forage cereals because they can produce more quantity and quality fodder while also ensuring net monetary returns and fodder cowpea and sunhemp are the next best suitable forage legumes under late-sown conditions in the semi-arid tropics of India.
An assessment of the effects of date of sowing and crop seasonal rainfall on the sustainability of yield and rainwater use efficiency (RWUE) of sorghum, pearl millet and foxtail millet sown on five dates at 15 days interval from first fortnight of June to first fortnight of August during 2009 to 2014 under arid Alfisols at Anantapur has been made in this paper. A suitable date of sowing has been identified for each crop based on the relationships sorghum equivalent yield with crop seasonal rainfall and crop growing period observed in the 6-year study. The yield was significantly influenced by the variation in the crop seasonal rainfall and crop growing period when sown on different dates of sowing. It was significantly higher when crops were sown with the onset of monsoon in the first fortnight of June, and decreased with the subsequent sowings. Among crops, sorghum attained maximum mean yield of 923 kg ha-1 with RWUE of 2.73 kg ha-1 mm-1; while pearl millet attained mean yield of 873 kg ha-1 with RWUE of 2.95 kg ha-1 mm-1 and foxtail millet attained mean yield of 646 kg ha-1 with RWUE of 1.64 kg ha-1 mm-1 when sown during first fortnight of June. Based on the ranks assigned to the yield attained on different dates of sowing in different years, pearl millet was superior for sustaining maximum yield and RWUE comparedto sorghum and foxtail millet under arid Alfisols at Anantapur.
