In the methods of providing water to crop, the drip system is the first in techniques that provide a high quality yielding and reduce water wastage. For the effective use of such a valuable drip system, we must have proper design and installation. When the drip design and installation is easier, then farmers are more likely to use it. The design and hydraulic performance of drip is all that makes sense for every one is the main objective. A field experiment was conducted at Dau Kalyan Singh College of Agriculture and Research Station, IGKV, Bhatapara to studies on irrigation and fertigation management on Chilli (Capsicum annuum) under drip system. The flow phenomena, design and hydraulic performance of drip irrigation were evaluated at 0.9, 1.0 and 1.2 kg cm-2 operating pressures with 2 lph emitter discharge. The soil moisture content at 15, 25 and 30 cm depth of the soil was evaluated by gravimetric method. The hydraulic performance measures such as uniformity coefficient, emission uniformity, and coefficient of manufacturing variation at different operating pressure for inline drip irrigation at 0.9 kg cm-2 was 89.13 %, 85.7 % and 0.065 kg cm-2, respectively, similarly for the operating pressure 1.00 kg cm-2, it was 92.5 %, 90.07% and 0.060 kg/cm2 and for 1.20 kg cm-2 it was 96.30 %, 94.30% and 0.042 kg cm-2. The uniform coefficient, emission uniformity, coefficient of manufacturing variation, application efficiency and discharge variation are found excellent at 1.2 kg cm-2 operating pressure. Fertilizers are increasingly used to increase investment by assuming that production is high. But with the use of the excess fertilizer, the production is not too high and soil health is also damaged. This results; it may be affected to the future growing crops in the soil. There is no use of excess fertilizer in the experiment done by various fertilizer levels in various water levels, it has been proved that using excess fertilizers, may not effected the production. The randomized block design has three drip irrigation levels (I1-60 per cent, I2-80 per cent and I3-100 per cent of pan evaporation) and one control (furrow) irrigation with three fertilizer levels (F1-100 per cent, F2-80 per cent and F3- 100 per cent of RDF through drip) on growth and yield of Chilli. The research experiment results revealed that application of 80 per cent ET with 100 per cent fertilizer level has maximum yield, number of fruits per plant, fruit weight per plant, fruit diameter, primary branches, secondary branches and stem girth were 24.80 t/ha, 78.44 numbers/plant, 261.35 g/plant, 1.18 cm, 11.8, 50.6 and 2.26 cm respectively and minimum was found in control irrigation in all aspects of plant growth and yield attribution. What these results says that, if they use excess water and fertilizers beyond the decline, they will not more effect on the yield. Chilli crop receiving irrigation supply at 80 per cent ET with a discharge rate of 2 lph and 100 per cent fertilizer application has highest gross income (Rs.496000 ha-1), net income (Rs. 397276 ha-1) and B:C ratio (4.02) than in other treatment combinations.ennullThesis
