A field experiment was conducted in Dalwangan, Malaybalay City and Manolo Fortich Bukidnon [Philippines] to determine the effect of Carrageenan PGP on the yield and yield components of two peanut varieties in two seasons. Treatments were: Farmers practice (No fertilizer application/Control), Carrageenan PGP alone (100ppm per applied 4x at 7 days interval from seedling emergence), Legume inoculants alone (Nitro Plus), and Carrageenan PGP + Legume inoculants. Yield and yield parameters of peanut was significantly associated with Carrageenan PGP and inoculant application regardless of season and variety. Significant increase in number of pods per plant and pod length was observed in peanut applied with both Carrageenan and legume seed inoculants. Highest seed yield were obtained in both seasons with Carrageenan PGP + legume and inoculants of 4,251 kg/ha (37% increased) in wet season and 2,584.9 kg/ha (32% increased) in dry season compared to farmers practice 2,645 kg/ha and 1,740 kg/ha, wet and dry season, respectively. Low incidence of Cercospora leaf spot and peanut rust in both variety and season was also observed in plants applied with Carrageenan PGP. Further, increased in net income to 318% was obtained using Carrageenan PGP and legume seed inoculant. This study confirmed the efficiency of Carrageenan PGP and legume seed inoculants in increasing yield and income of peanut farmers.
