The present study on Performance evaluation of Sweetcorn with different levels of Irrigation and nitrogen through drip during post monsoon season at Rajendranagar, Hyderabad, India was conducted for two years at Maize Research Centre, Agricultural Research Institute (ARI), Rajendranagar, Hyderabad to assess the influence of different levels of irrigation and nitrogen on performance of sweetcorn hybrid. Randomized block design with factorial concept was used in the study and the experiment was replicated thrice. The treatments used were two factors. Factor I was five irrigation levels viz., I1: Drip irrigation at 60% E pan, I2: Drip irrigation at 80% E pan, I3: Drip irrigation at 100% E pan, I4:Drip irrigation at 120% E pan andI5: Surface irrigation at IW/CPE- 1.0 and Factor II was four nitrogen levels in kg ha-1 viz., N1: 120, N2: 160 N3: 200 N4: 240. Pooled mean of two years revealed that, drip irrigation with 120% E pan which was on par with 100% E pan showed significantly better crop performance in terms of growth characteristics like plant height, Leaf Area Index and dry matter production and both were superior to drip irrigation of 80 and 60% E pan as well as surface irrigation method. Among the yield attributes, cob girth and 100 seed weight were not influenced either with irrigation or nitrogen and their interaction. Cob length, number of seeds row-1, green cob and fodder yield were higher with drip irrigation of 120% E pan but were on par with 100% E pan. Among the different nitrogen levels, nitrogen at the rate of 240 kg ha-1recorded significantly higher growth parameters, yield attributes, green cob and fodder yield but it was on par with 200 kg ha-1 and both were superior over 160 and 120 kg N ha-1. Drip irrigation of 100% E pan and a nitrogen level of 200 kg ha-1 resulted in higher gross and net returns and benefit cost ratio compared to other irrigation and nitrogen treatments. From the study, drip irrigation of 100% E pan with 200 kg N ha-1is recommended for getting higher yields and net income in sweetcorn hybrid grown in Southern Agro climatic zone of Telangana, India.

The present experiment on Performance evaluation of drip irrigation system and profitability analysis of leafy vegetables under polyhouse was conducted to study the performance parameters of the drip irrigation systems relating to crop performance. This was done by taking existing drip tapeline, new drip tape line and new inline drip irrigation system under the Polyhouse at the college of Agricultural Engineering, Kandi, Sangareddy, Telangana during the year 2018. Profitability of five green leafy vegetables viz. Palak, Sorrel, Methi, Amaranths and Coriander was also evaluated. The results reveal that the three drip line systems in-line got more uniform coefficient of 98% followed by new drip tape with 96% and preinstalled drip tape with 95%. Among the five green leafy vegetables methi has recorded highest gross (306000Rs acre-1) and net returns (285833) and benefit cost ratio (14.2) followed by Palak, Sorrel whereas Amaranthus has recorded lowest benefit cost ratio (7.6).  In terms of performance characteristics, drip tape and in line system performed better in maintaining uniformity discharge and the designed drip irrigation operated excellently.  Methi, Palak ad sorrel found suitable and profitable in polyhouse where year- round cultivation of vegetables is feasible compared to open field in which crop establishment was very poor and could not be raised successfully due the heavy rains and growth characters of the leafy crops.

Fertigation was found technically and economically feasible for tomato cultivation in winter as well as in summer. An experiment was conducted with summer tomato (BARI Hybrid Tomato–4) having 2 drip irrigation levels with different levels of NPK and micronutrient (B, Zn, and Mg) during kharif-1 seasons of 2007 and 2008. The fertilizer levels were N100 P55 K120 kg/ha, N100 P55 K120 B1 Zn4 Mg4 kg/ha, N100 P70 K140 kg/ha and N100 P70 K140 B2 Zn6 Mg8 kg/ha and the irrigation levels were drip irrigation at 2 days interval and drip irrigation at 3 days interval. The highest marketable yield of summer tomato (35.90 t/ha and 27.12 t/ha) were obtained from the fertigation treatment with fertilizer doses of N100 P55 K120 B1 Zn4 Mg4 kg/ha irrigated at 2 days interval in 2007 and 2008. The cull yield was also the lowest (2.53 t/ha and 1.15 t/ha) in this treatment in both the years. The lowest tomato yield (20.50 t/ha and 18.29 t/ha) were obtained from the treatment with fertilizer doses N100 P70 K140 kg/ha irrigated at 2 days interval where no micronutrients were used. Fruit quality parameters like TSS, Vitamin-C and ?-carotene were also the highest for the best yielder. So, use of micronutrients with NPK showed a significant effect on quality fruits as well as yield of summer tomato. The best yielder treatment received 261.0 mm of seasonal water including an effective rainfall of 60.5 mm during the crop seasons. The highest BCR (4.41) was also found in the same treatment.
