Yield in g/plant as influenced by different drip system layout.
With respect to the number of branches, it was observed that the maximum number
of branches in the case of irrigation level was 8 in I3. In case of number of branches
of 7, the level of irrigation I2 was on par with the irrigation level I3. The number of
branches of 6 in the irrigation level I2 was on par with the I1. The minimum number of
branches was observed for the irrigation level I1 at 120 days after planting.
For average yield, the different levels of irrigation and the drip system layout
showed signifi cant difference. The maximum yield value for irrigation level was ob-
served in I3 (18.137 t/ha), 85% of the irrigation requirement. The minimum yield was
observed for the irrigation level I1 (12.488 t/ha), 65% of the irrigation requirement.
When different drip system layout were taken into consideration, the maximum yield
was obtained for the drip system layout D1 (15.271 t/ha), one lateral for each row of
crops and the minimum yield was obtained for the drip system layout, D2 (14.289 t/
ha), one lateral in between two rows of crops. This can be attributed to the fact that
high moisture level in one lateral for each row of crops helps in better fruit weight per
plant as compared to the plants with one lateral in between two rows of crops.
12.3.2 WATER USE EFFICIENCY AND FERTILIZER USE EFFICIENCY
The highest water use efficiency of 25 kg/ha/mm was recorded in treatment T5 and T1.
The reason for maximum water use efficiency in T1 was due to lesser water require-
ment as compared to T6. The water use efficiency of 25 kg/ha/mm for treatment T1
was higher than the water use efficiency of 23 kg/ha/mm for the treatment T3. This
was due to lesser water requirement as compared with the treatment T3.
Increased FUE, such as Nitrogen use effi ciency (NUE) and Potassium use effi -
ciency (KUE), with the decreased levels of fertilizer doses were observed in the chili
crop. The highest NUE of 244.26 kg of produce per kg of N was recorded in the treat-
ment T5. Similar fi ndings were observed by Vijayakumar, et al. [3]. For the treatment
T6 the NUE of 239.36 kg of produce/ kg of N was recorded and for the control was
about 60.5 kg of produce per kg of N.
The similar trend was observed in KUE in chili crop. The maximum KUE of 732.8
and 718.08 of kg of produce/ kg of K were observed in treatments T5 and T6, respec-
