(2017).Effect of polyethylene mulch and drip fertigation on production of chilli crop.Irrigation and Drainage Engineering Department,Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola.M. Tech. 2017. Print. xii, 94p.(Unpublished).http://krishikosh.egranth.ac.in/handle/1/5810061908Chilli (Capsicum annuum L.), the most widely used and universal spice of India, belongs to the Solanaceae family. This has high medicinal value especially anti cancerous and instant pain relief. Water resources are deteriorating in terms of quality as well as quantity.Improper irrigation management practices cause not only wastage of expensive and scarce water resources but also decreases crop yield, quality, water use efficiency. It is necessary to adopted some pressurised irrigation practices with mulch to achieve maximum yield at lower amount of water. So we can use silver -black polyethylene mulch along with 80% ET which can save water up to 15% and gives maximum production of green chilli.The present study entitled “Effect Of Polyethylene Mulch And Drip Fertigation On Production Of Chilli Crop” was conducted during 28thJuly 2016 to 16thJanuary 2017 at Chilli and Vegetable Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. in kharifseason. The study indicated higher plant growth, more number of fruits per plant and enhancement in the yield under all drip irrigation with mulch. Yield of green chilli was maximum in the treatment of drip irrigation at 80% ET with mulching (188.40 q/ha) and found to be at par with the treatment of drip irrigation at 100% ET with mulching (169.69 q/ha) directly reflects 15.72 per cent water saving with comparable yield. Minimum yield of chilli was found in the treatment drip irrigation at 100% ET without mulching (103.87 q/ha). Highest irrigation water use efficiency 5.76 q/ha-cm was found in the treatment of 80% ET with mulching. Highest weed weight was observed in control treatment of 100% ET without mulch and negligible weed growth was found in all mulching treatment. On the basis of benefit cost ratio it is economically viable for the farmers to adopt drip irrigation at 80% ET with mulching for green chilli which shows B:C ratio 2.17.ennullThesis
