Abstract
A field experiment entitled “Effect of mulching on vegetables as intercrop in the Kinnow orchard under agro-climatic condition of Bastar plateau of Chhattisgarh” was conducted during the Rabi season of 2016-17 at the Instructional farm, College of Horticulture and Research Station, Jagdalpur (C.G.). The experiment was laid out in T-test with three replications. The treatment consisted of mulched and non mulched plots in four different crops viz., tomato, chilli, brinjal and bitter gourd. Observations on 13 important characters viz., plant height, number of branches plant-1, number of fruits plant-1, days taken to 1st flowering, days taken to 50 per cent flowering, leaf area, nutrient uptake (N,P and K), maximum days taken to 1st harvesting, protein per cent, total soluble solids, vitamin C, yield plant-1 and yield ha-1 were recorded during the experimentation. The data regarding growth studies and its components, correlation and B: C ratio has also been summarized below: Perusal of data in the mulched tomato plots revealed the maximum plant height (59.85cm), number of branches plant-1 (26.53), numbers of fruits plant-1 (43.93), days taken to 1st flowering (42), days taken to 50 per cent flowering (61%), leaf area (16.69cm), nutrient uptake (123.27,14.21 and 110.81 kg ha-1 N, P and K respectively), days taken to 1st harvesting (78.00), protein percent (7.75%), TSS per cent (4.56%), vitamin C (25.08 mg/100g), yield plant-1 (13000g) and a total yield ha-1 (130.33q). preformed of mulch chilli plots the maximum plant height was recorded to be (60.64cm), number of branches plant-1 (37.47), numbers of fruits plant-1 (58.73), days taken to 1st flowering (35.67), days taken to 50 per cent flowering (55.67), leaf area (62.46 cm), nutrient uptake (74.65, 13.04 and 77.44 kg ha-1 N, P and K respectively), days taken to 1st harvesting (76.67), protein per cent (2.80%), TSS per cent (4.37%), vitamin C (120.04 mg/100g), yield plant-1 (3000g) and the total yield ha-1 (30q). The mulched plots of brinjal recorded the following maximum datas viz., plant height (52.61cm), number of branches plant-1 (21.53), numbers of fruits plant-1 (11.73), days taken to 1st flowering (42.33), days taken to 50 per cent flowering (61.0), leaf area (57.66cm), nutrient uptake (222.22,33.34 and 107.99 kg ha-1 N, P and K respectively), days taken to 1st harvesting (77.33), protein per cent (15.00%), TSS per cent (5.27%), vitamin C (15.41 mg/100g), yield plant-1 (20000g) and the total yield ha-1 (200q). While the mulched plots of bitter gourd recorded the maximum plant height of (191.51cm), number of branches plant-1 (29.67), numbers of fruits plant-1 (42.27), days taken to 1st flowering (66.33), days taken to 50 per cent flowering (86.67), leaf area (43.15cm), nutrient uptake (47.67,7.63 and 41.20 kg ha-1 N, P and K respectively), days taken to 1st harvesting (95.67), protein per cent (1.62%), TSS per cent (1.34%), vitamin C (46.21 mg/100 g), yield plant-1 (10666.67g) and the total yield ha-1 (101.66q). However in the non mulched plots the datas were comparatively low for all the four crops viz., tomato, chilli, brinjal and bitter gourd than the mulched plots. The present investigation revealed that among the mulched and non mulched treatments, plastic mulch recorded comparatively higher yield attributes and higher economic returns in tomato (2.66), chilli (1.25), brinjal (2.55) and bitter gourd (4.85) when raised as intercrops in the kinnow orchard.
