dc.description.abstractA field experiment was conducted at Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar, during the autumn season of 2018-19, to study the influence of high intensity intercropping on the performance of sugarcane ratoon crop under pressurize irrigation. The experiment was laid out in randomized block design, replicated thrice with eight different treatments viz., sole sugarcane paired row (PR) with surface irrigation (T1), sole sugarcane PR with drip irrigation (T2), sugarcane PR + French bean (3 rows) with surface irrigation (T3), sugarcane PR + French bean (3 rows) – green gram (3 rows) with surface irrigation (T4), T4 + residue incorporation of green gram (T5), sugarcane PR with drip irrigation + French bean (3 rows) with micro-sprinkler irrigation (T6), sugarcane PR with drip irrigation + French bean (3 rows) – green gram (3 rows) with micro-sprinkler irrigation to both the intercrops (T7) and T7 + residue incorporation of green gram (T8). Different treatments had a significant influence on growth parameters, yield attributes, and yield of sugarcane. The plant population recorded at different stages of growth was found to be significantly affected by different treatments. Experimental results indicated that treatment T2 (sole sugarcane PR with drip irrigation) produced a higher plant population at all the growth stages which were responsible for a higher number of millable canes at harvest. Similarly, treatment T2 showed significantly higher values of leaf area index, plant height, number of millable canes, brix, pol, and CCS percent. However, cane diameter, single cane weight, and purity percentage in the juice were found non-significant. The data on growth parameters, yield attributes, and yield of French bean indicated that the treatment T8 recorded higher plant height (51.2 cm), number of branches/plant at harvest (4.5), number of pods/plant (8.2), number of seeds/pod (5.0), 100- seed weight (47.8 g), and grain yield (1.75 t/ha) as compared to other treatments. Similarly, the growth parameters, yield attributes, and yield of green gram viz., plant height, number of branches/plant at harvest, number of pods/plant, number of seeds/pod, 1000- seed weight, and grain yield, recorded highest values 68.6 cm, 4.4, 24.5, 12.2, 31.8 g, and 1.14 t/ ha, respectively under the treatment T8 as compared to other treatments. Planting of sole sugarcane PR with drip irrigation produced significantly higher cane (102.1 t/ha) and sugar yield (12.3 t/ha). The results obtained from the analysis revealed that though the water requirement was comparatively higher (126.92 cm) under treatment T7 (sugarcane with drip irrigation + french bean – green gram with micro-sprinkler irrigation to both the intercrops), however, water use efficiency (1382.53 kg/ha-cm) and water productivity (13.83 kg/m3) were comparatively higher under sole sugarcane with drip irrigation (T2), it was found to be drip irrigation were economically better than surface irrigation method. Fractionation of soil organic carbon showed comparatively higher values of SOC under sugarcane with drip irrigation + French bean – green gram with micro-sprinkler irrigation to both the intercrops + residue incorporation of green gram (T8) followed by sugarcane with drip irrigation + French bean – green gram with micro-sprinkler irrigation to both the intercrops (T7). Economics of different treatments indicate that the higher cane equivalent yield (153.2 t/ha), gross return (`474900/ ha), and net return (`306500/ ha) were registered with sugarcane with drip irrigation + french bean – green gram with micro-sprinkler irrigation to both the intercrops + residue incorporation of green gram (T8). However, higher benefit: cost ratio (2.13) obtained with sole sugarcane with drip irrigation which was statistically similar to T1 and T8.en_US
