    Effect of different leguminous crops on soil and growth under Jackfruit (Artocarpus heterophyllus Lam.) based Agroforestry system
    (Birsa Agricultural University, Ranchi, 2023) Hemlata Gupta; J.K. Kerketta)
    The present investigation entitled “Effect of different leguminous crops on soil and growth under Jackfruit (Artocarpus heterophyllus Lam.) based Agroforestry system” was carried out at nursery site of faculty of forestry, Birsa Agricultural University Kanke, Ranchi during April to June 2022 with objectives: (1) To study the growth behaviour of Artocarpus heterophyllus Lam. (2) To study the yield of leguminous crops, and (3) To study the chemical properties of soil under irrigated condition. The experiment was laid out as per Randomized Block Design consisting of five treatments with four replications. The treatments were T1 (Jackfruit + Black gram), T2 (Jackfruit + Green gram), T3 (Jackfruit + Cowpea), T4 (Jackfruit + French bean) and T5 (Jackfruit sole). The experiment was conducted on 2-year-old Jackfruit (baramasi) plants with spacing 5m x 5m. The intercrops grown were black gram, green gram, cowpea and French bean. The various growth parameters for the of Jackfruit plants viz. plant height, collar diameter, number of branches per plant, number of leaves per plant were studied to access the effect of leguminous crops on growth of Jackfruit plant. Different yield attributes of all leguminous intercrops were recorded and analysed to find the yield. Various soil chemical properties were also recorded and analysed to access the effect of leguminous crops on soil under Jackfruit-based agroforestry system. As per the result of the experiment, growth parameters of jackfruit plants were positively affected by growing leguminous intercrops in the interspaces between the trees. All the growth parameters of jackfruit plants recorded and analysed were significant. Jackfruit + Cowpea (T3) recorded maximum plant height (148.1 cm), collar diameter (2.69 cm), number of branches (14.02) and number of leaves (333.0) followed by Jackfruit + Black gram (T1), Jackfruit + Green gram(T2), and Jackfruit + French bean (T4). The minimum was recorded by Jackfruit sole (T5). Cowpea equivalent yield of all four leguminous intercrops varied significantly. The maximum (134.46 q ha-1 ) cowpea equivalent yield was recorded for Jackfruit + Cowpea (T3) which was significantly higher than Jackfruit + French bean (T4), Jackfruit + Green gram (T2) and Jackfruit + Black gram (T1). Soil chemical properties viz. soil pH (6.075), organic carbon (0.395%), available nitrogen (241.0 kg ha-1 ), available phosphorus (72.0 kg ha-1 ) and available potassium (168.0 kg ha-1 ) were also found significant with Jackfruit + Cowpea (T3) recorded maximum and Jackfruit sole (T5) recorded minimum. Leguminous intercrops have positive effect on growth of jackfruit plants during establishment period. Cowpea had the best effect on growth jackfruit plants. Leguminous intercrops add to the fertility of soil by enhancing the soil health.Among the leguminous intercrops taken for study Cowpea had the best effect on soil and growth of Jackfruit plants and also in terms of yield, cowpea showed the best result therefore,Cowpea can be taken as intercrop in Jackfruit-based agroforestry system.
