Abstract:
An experiment was conducted to assess the Effect of drip irrigation and mulching on growth of cashew nut envisaged to evaluate the scheduling of irrigation at different pan co-efficient (e pan) in combination with different mulching method in private cashew orchard at Arjunpur, Khurdha in 2015-16. Experimental comprised of 192 number of grafted planted c.v. Venggrula-4 at the 3^rd year at spacing of 7m X 7m. Taking into account the scheduling of irrigation at different levels of E pan and kinds of mulching material used in six treatment combination. I1M1-No irrigation + No mulching (control), I1M2- No irrigation + Paddy straw mulch, I₁M3₃- No irrigation + Green leaf mulch, I₁Mâ‚„- No irrigation + LDPE mulch. Iâ‚‚M₁- Irrigation at 0.6 E pan + No mulch, Iâ‚‚Mâ‚‚- Irrigation at 0.6 E pan ₊ Paddy straw mulch, Iâ‚‚M₃- - Irrigation at 0.6 E pan + Green leaf mulch, Iâ‚‚Mâ‚„- Irrigation at 0.6 E pan ₊ LDPE mulch. I₃M₁- Irrigation at 0.8 E pan + No mulch, I₃Mâ‚‚- - Irrigation at 0.8 E pan ₊ Paddy straw mulch, I₃M₃- Irrigation at 0.8 E pan + Green leaf mulch, I₃Mâ‚„-- Irrigation at 0.8 E pan + LDPE mulch The study revealed that the plant height in both seasonal observation attained under the drip irrigation scheduled at 1.0E pan i.e. fulfilling 100% water requirement of the plant per days as calculated but mulching alone expressed no significant effect on plant height and in combination of irrigation at 1.0E pan along with LDPE mulching the result became conspicuous with highest plant height
