    Effect of irrigation levels through micro-sprinklers on growth and yield of potato
    (CCSHAU, 2011) Ahlawat, Sachin; Baswana, K.S.
    The experiment entitled “Effect of irrigation levels through micro-sprinklers on growth and yield of potato” was conducted at Research Area Hi-Tech Greenhouse, Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during winter (rabi) season of 2009-10. The experiment comprising of five irrigation levels (6 mm, 8 mm, 10 mm, 12 mm of 10 mm CPE and control at 40 mm furrow irrigation) and two cultivars (Kufri Bahar and Kufri Badshah) was laid out in a split–plot design with four replications keeping net plot size 3.6 x 3.6 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different irrigation levels and cultivars except in weight of tubers of >50-74g grade where cultivar showed non significant difference. The per cent plant emergence at 15, 20, 25 and 30 DAP, plant height at 45,60,75 and 90 DAP, number of stems per hill, number of leaves per stem, leaves weight per hill, stem weight per hill, leaf area index, weight of foliage, number of tubers >25-50 g, >50-75 g and >75 g grade, total number of tuber/m2, weight of tuber >25-50 g, >50-75 g and >75 g grade and total tuber yield, marketable yield were significantly higher at 12 mm of 10 mm CPE level of irrigation applied through micro-sprinkler irrigation. However, number of tubers up to 25 g grade and weight of tubers up to 25 g grade were maximum at 10 mm of 10 mm CPE level of irrigation. Both the cultivars exhibited significant difference for growth and yield. The maximum value for per cent plant emergence at 15, 20, 25 and 30 DAP, plant height 45, 60, 75 and 90 DAP, number of leaves per stem, leaves weight per hill, number of stems per hill, stem weight per hill, leaf area index and weight of foliage, number of tubers up to 25 g, >25-50 g, 50-75 g and >75 g grade, total number of tubers/m2, weight of tubers up to 25 g, >25-50 g, >50-75 g and >75 g grade, total tuber yield, marketable yield were maximum with cultivar Kufri Badshah. However, harvest index was observed maximum with cultivar Kufri Bahar. These observations showed that Kufri Badshah responded more to micro-sprinkler irrigation. Interaction effect of irrigation levels and cultivars showed remarkable variation for growth and yield parameters except for per cent plant emergence at 30 DAP. Maximum plant emergence was registered at 15, 20, 25 and 30 DAP, plant height at 45, 60, 75 and 90 DAP, number of leaves per stem, leaf area index, stem weight per hill, weight of foliage, number of tubers of >50-75 g grade, number of tubers of >75 g, total number of tuber/m2 grade, weight of tubers >25-50 g grade, >50-75 g grade and >75 g grade at 12 mm of 10 mm CPE level of irrigation with cv. Kufri Badshah. However, number of tubers up to 25 g grade and weight of tubers up to 25 g grade was found maximum at 8 mm of 10 mm CPE irrigation level in Kufri Badshah. Kufri Badshah produced higher total and marketable yield than Kufri Bahar at 12 mm of 0 mm CPE applied through micro-sprinkler irrigation.
