Abstract
Livestock play a significant role in countries economy. Livestock production is mainly limited by insufficient fodder and poor nutrition. Effective utilization of organic manures plays an effective role in proper nutrition and increasing the green fodder production of fodder crops. In this context an experiment was conducted to study the effect of different organic manures on the green fodder yield of Dolichus trilobus in Punica granatum based hortipasture system with different organic manure practice. Pillipesara (Dolichus trilobus) was grown on a degraded wasteland under Punica granatum based hortipasture system in North Eastern Agroclimatic zone of Tamil Nadu during 2017. The experiment was laid out in Randomized Complete Block Design (RCBD) with four treatments replicated thrice. Treatments consisted of three different manures on N equivalent basis viz., cattle manure, goat manure, swine manure and a control (without manure). Manures were incorporated as per the treatment as basal application. Fodder was harvested on 60th day at different places and fresh weight was recorded and Dry matter production (DMP) was estimated. Harvested plant material was weighed, dried and the ground subsamples were taken for analysis of crude protein (CP) and crude fibre (CF) as per AOAC, (2000) method. The growth performance of Dolichus trilobus revealed that application of 100% cattle manure on Nitrogen equivalent basis performed better in terms of fresh fodder yield (17.58 MT/ha) and dry fodder yield (3.52 MT/ha) under Punica granatum based hortipasture system. Higher crude protein of 16.52 % and crude fibre content of 21.24 % was observed with the application of 100% cattle manure on Nitrogen equivalent basis treatment. Hence, application of 100 % Cattle manure on N equivalent basis can be effectively utilised as a source of nutrient for the crop to enhance the nutrient composition of the fodder crop grown in the system.
