    (Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2021) Komal Kiran; Singh, Jainendra Kumar
    An experiment was conducted on “Effect of phosphorus and lime on Indian mustard (Brassica juncea L.) under wood apple (Aeglemarmelos L.) based agri-horti system” at agroforestry farm of Rajiv Gandhi South Campus, BHU,Barkachha, Mirzapur, Uttar Pradesh. The experiment was conducted in Factorial Randomised Block Design with ten treatments (30 kg P2O5 + 150 kg lime ha-1, 30 kg P2O5 + 300 kg lime ha-1 , 30 kg P2O5 + 450 kg lime ha-1 , 50 kg P2O5 + 150 kg lime ha-1 , 50 kg P2O5 + 300 kg lime ha-1 , 50 kg P2O5 + 450 kg lime ha-1, 70 kg P2O5 + 150 kg lime ha-1 , 70 kg P2O5 + 300 kg lime ha-1, 70 kg P2O5 + 450 kg lime ha-1, control (no P2O5 + no lime).The objective of the present study was to generate information on the assessment of growth and yield of Indian mustard effected by phosphorus and lime levels. Progressive increase in phosphorus and lime levels up to 70 kg P2O5ha-1and 450 kg lime ha-1, respectively have significantly increased the growth and yield parameters of the cropviz. plant height,number of secondary branches, dry matter accumulation, siliqua length, number of siliquae, seeds per siliqua, seed yield and stover yield.

    Effect of phosphorus levels and biofertilizers on chickpea (Cicer arietinum L.) under guava (Psidium guajava L.) based agri-horti system
    (Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2021) Priya, Swati; Singh, Jainendra Kumar
    An experiment was conducted during the Rabi season of 2020-21 at the RGSC, BHU, Mirzapur (Uttar Pradesh) in a thirteen-year-old guava (Psidium guajava L.) orchard with sandy loam soil with moderate fertility, (pH 5.9) to assess the growth, productivity and economics of chickpea (cv. Pusa-362) under agri-horti system and growth of guava tree. The experiment was laid in Factorial Randomised Block Design with ten treatments (30 kg P2O5 ha-1 alone, 45 kg P2O5 ha-1 alone, 60 kg P2O5 ha-1 alone, 30 kg P2O5 ha-1 with Rhizobium, 45 kg P2O5 ha-1 with Rhizobium, 60 kg P2O5 ha-1 with Rhizobium, 30 kg P2O5 ha-1 with Rhizobium and PSB,45 kg P2O5 ha-1 with Rhizobium and PSB, 60 kg P2O5 ha-1 with Rhizobium and PSB, the control (no phosphorus and biofertilizers). In chickpea, the highest growth parameters and yield attributes of chickpea were recorded with progressive increase in phosphorus level up to 60 kg P2O5 ha-1 with dual inoculation of seeds with Rhizobium and PSB proved to be profitable boosting grain yield (1568 kg ha-1) and gave the maximum net return (Rs. 65460 ha-1). Under agri-horti system, guava + chickpea (application of 60 kg P2O5 ha-1 with dual inoculation of seeds of chickpea with Rhizobium and PSB) gave highest net returns (Rs.153070 ha-1) and B-C ratio (2:69) as compared to other treatments integrated with guava fruit tree. The highest tree height, canopy diameter, stem girth and fruit size of guava was recorded in association with chickpea.
