Performance of intercropping in pre-bearing mango orchards under drip irrigation in a degraded land

A field experiment was carried out to evaluate the performance of pre-bearing mango plantation with different intercrops (papaya, pineapple and combination of papaya and pineapple) in a sandy clay loam soil on a degraded land under drip irrigation at ICAR-Indian Institute of Water Management, Bhubaneswar, Odisha during 2017-18. Different intercrops planted in the mango (cv. Amrapali) were (i) two rows of papaya (cv. Red lady) in either side of mango plants, (ii) two paired rows of pineapple (cv. Queen) in either side of mango plants and (iii) one row of papaya and one paired row of pineapple in either side of mango plants with and without paddy straw mulch. All plants were irrigated by drip irrigation (DI) system. The amount of water used in mango–papaya cropping system (1220 mm) was higher than that in mango-pineapple cropping (975 mm). The volumetric soil water content in top 0.60 m soil in mango, papaya and pineapple were 20-23%, 21-24% and 22-24%, respectively. The vegetative growth parameters (plant height, canopy diameter and trunk girth) of young mango plants were not affected significantly either by papaya or pineapple intercropping. Straw mulch enhanced the growth parameters of mango plants by 8-12%. Similarly, growth parameters of papaya and pineapple were not affected significantly either by intercrops or by straw mulch. The highest yield (17.5 t/ha) and water productivity (21.1 kg/ha.mm) were observed in mango–pineapple system with straw much. The net profit from pineapple intercropping with straw mulch was highest (Rs. 140000/ ha) with benefit-cost ratio of 1.67, followed by papaya-pineapple intercropping with straw mulch in mango. Overall, the study reveals that mango intercropped with pineapple under drip irrigation with rice straw mulch can be practiced in pre-bearing mango orchards of Eastern India

The change in vegetation (i.e. NDVI) between the year 2000 and 2009 shows a notable shift from other land-use classes to agricultural practices, with a 15% increase in area under vegetation during the pre-monsoon summer season. This indirectly point to the increased groundwater utilization, because farmers use their own shallow tube well or purchase water from others to grow the summer paddy. As a case study, a tank-cum-well system, with a tank of 80 m length, 60 m width and 2 m depth, has been created. In 2014, with delayed arrival of monsoon rainfall and persistent dry spells, the harvested volume of 10000 m3 of water provided the life-saving irrigations. To improve the water productivity, fish farming was undertaken with a stock of about 2000 fishes, each grew to about 450 grams within 3 months. Moreover, a 2 m width and 0.15 m depth earthen platform was made around the recharge structure in which 500 banana plants were grown, along with perennial fruit crops. In the first year, a gross return of Rs. 75,000 has been estimated.Not Availabl

Not AvailableThe cat tail (Typha elephantina), a non-food commercial crop grows as an emergent hydrophyte in tidal waterlogged areas. Its leaves are used for preparing mats and used as roof top and wall partition. Typha sp. has been found to be efficient accumulator of N from sediment under waterlogged condition. The N utilization mainly through nitrate reductase (NR) activity was studied in Typha with four levels of N fertilizers i.e. 0,30 and 60 and 90 kg ha-1 applied at three stages of plant growth i.e. basal, 3 and 6 month after planting. In general, there was reduction in NR activity under waterlogged condition in Typha. But application of @ 90 kg ha-1 maintained high NR activity when it was applied as basal stage. Basal application of N was found better than its application at 3 or 6 month stage of crop growth. The higher leaf NR activity at 60 and 90 kg ha-1 N application level suggested better N utilization under waterlogged environment. The photosynthesis rate showed significant increase with higher N application concomitant with greater stomatal conductance (r = 0.84 * * ; n = 12). There was significant increase in leaf yield when N was applied @ 90 kg ha-1 N level as basal dosage as compared to later stage (3 or 6 months) of crop growth. The highest fertilizer use efficiency (kg dry leaf kg-1 applied N) was also found at 90 kg N ha-1 as compared to 30 or 60 kg ha-1 N level, which corroborated superior N fertilizer utilization ability of Typha under waterlogged condition.Not Availabl
