:10' E and altitude of 250 m). The experiment was arranged in twelve treatment combinations with strip plot design as horizontal factor (main treatment) one continuous irrigation (P 1 ), two pulses (P 2 ), three pulses (P 3 ) and four pulses (P 4 ), while vertical factor (sub treatment) as irrigation levels viz., I 1 (0.80 ET C ), I 2 (1.0 ET C ) and I 3 (1.20 ET C ) treatments. It was revealed that the average seasonal water applied to white onion under pulse irrigation (drip) through different irrigation levels varied from 276.8 mm for I 1 (0.8 ET C ) to 429.0 mm for I 3 (1.2 ET C ) irrigation levels. Among the different treatment combination I 2 P 4 (irrigation level I 2 (1.0 ET C ) with four pulse treatment P 4 ) was found 38.52 t.ha -1 and significantly superior over I 1 P 1 (irrigation level I 1 (0.8 ET C ) with continuous irrigation P 1 ). The production cost of Rs. 4,47,366 and Rs. 4,42, , gross returns of Rs. 9,63,000 and Rs. 9,31,500 ha -1 , net returns of Rs. 5,15,634 and Rs. 4,88,538 ha -1 and B C ratio of 2.15 and 2.10, were observed for I 2 P 4 and I 3 P 4 treatment combinations, respectively. Average water use efficiency was found maximum for I 1 P 4 (11.93 q ha -1 cm -1 ) treatment combination followed by I 1 P 3 (11.33 q ha -1 cm -1 ) and I 2 P 4 (10.99 q ha -1 cm -1 ) treatment combinations, respectively.
Konkan is a coastal strip parallel to Sahyadri hill ranges, which rises from mean sea level to 300 meter height having annual rainfall range from 2300 mm to 4100 mm (Anonymous, 2013).Climate change is acting as a trigger for changing rainfall pattern and temperature which can have significant impacts on hydrological cycle and crop calendar of the region (Abrol et al., 2004). Mono-cropping with rice cultivation during kharif season is generally observed while the horticultural crops like mango, cashew and coconut are major crops of the region. In last few years' production, productivity and quality of mango is adversely affected due to change in different meteorological parameters in the region (Munj et al., 2017). The variability in rainfall and temperature of the Konkan region has been reported by various workers (Dixit et al., 2005;Yadav and Dixit, 2006;Talathi et al., 2008). However no work is reported on trends in the climatic parameters of this region. Hence, the presents study was undertaken to analyse the trends in annual and seasonal rainfall and temperaturein the Konkan region.The daily rainfall, maximum and minimum temperature data of twelve locations (Table 1) was collected from Department of Agronomy, Dr.Balasaheb Sawant Konkan KrishiVidyapeeth, Dapoli and Water Resource Department, Hydrological Project, Government of Maharashtra, Nasik. The daily data were converted in to seasonal (kharif from 23 rd to 41 st SWM, rabi from 42 nd to 8 th SWM and summer from 9 th to 22 nd SWM) and annual.Trend analysis was statistically examined in two phases i.e., initially the presence of a monotonic increasing or decreasing trend was tested using the non-parametric Mann-Kendall test (Mann, 1945;Kendall, 1995). Then the rate of change was estimated with the help of Sen's slope test (Sen, 1968). The slope of the trend line indicates the rate and direction of change. The significance of results were tested at 90, 95 and 99 per cent confidence levels.
The experiment was conducted during year 2008-09 at Hi-Tech Project, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri under shed net condition to study the response of coloured capsicum for different irrigation and fertilizer levels in terms of growth and yield. The study concluded that the coloured capsicum showed positive response to the different irrigation and fertilizer levels under shed net house over open field condition. The alternate day irrigation and split application of WSF fertilizers with different levels through drip irrigation system responded well by coloured capsicum in terms of growth and yield. The higher levels of irrigation and fertilizer were also boost the yield of coloured capsicum under shed net house. The study suggested that treatment I 3 F 3 (1.0 PE, 120 % RD) gave maximum gross monetary returns (Rs. 239.50/m 2 ) and B:C ratio. (8.60).
