Special information system i.e Remote Sensing (RS) and Geographical Information System (GIS) and Global Positioning System (GPS) has proved to be an efficient tool in delineation of drainage pattern and water resources management and its planning. GIS and image processing techniques have been adopted for the identification of morphological features and analyzing their properties of the Yesegaon watershed sub-basin area in jintur taluka of maharashtra state, India. The basin morphometric parameters such as linear aerial and relief of the river basin where determine and computed. It is 6 th order drainage basin and drainage pattern mainly in sub dendritic to dendritic type. It is observed that the drainage density value is low i.e. 1.59 km/km 2 which indicate the basin is highly permeable subsoil and thick vegetative cover. The circularity ratio value is 0.28 basin is reveals that the basin is strongly elongated and highly permeable homogenous geologic materials. This study will help the local people to utilize the resources for sustainable development of the basin area.

A field experiment entitled "Impact of Irrigation and Fertigation Levels on Growth, Yield and Quality of Summer Chilli (Capsicum annuum L.)" was carried out during summer season of 2018, in split plot design having main plot treatments as drip irrigation levels viz. I1: at 0.7 ETc, I2: at0.8 ETc,I3: at 0.9 ETc, I4: at 1.0 ETc, and I5: at 1.1 ETc and Sub-plot treatments as fertigation levels viz. F1= 60 per cent of RDF, F2= 80 per cent of RDF and F3= 100 per cent of RDF with fifteen treatment combinations, replicated thrice. Results of the study indicates that the significant differences on chilli yield and quality attributes viz., per cent fruit set, fruit length, girth and number of fruits per plant were observed for different drip irrigation and fertigation levels. As drip irrigation levels between 80 to 100 per cent of crop evapotranspiration were found statistically at par with each other for fruit quality and yield of chilli, irrigation level of 80 per cent of crop evapotranspiration was found optimum among the all tested treatments. Whereas, for different levels of fertigation in eleven splits had significant effect on fruit quality and yield of chilli. Fruit quality and yield of chilli was found highest in F3 (fertigation with100% of RDF) treatment. Further fertigation levels with100 per cent of RDF and 80 per cent of RDF was found statistically at par with each other for the fruit quality and yield of chilli. Therefore, fertigation with 80 per cent RDF in eleven splits was found optimum. Interaction effect of different irrigation and fertigation level was found non-significant.

Crop models are useful for different purposes; primarily, to interpret experimental results and as research tools for research knowledge synthesis. Lengthy and expensive field experiments, especially with a high number of treatments, can be pre-evaluated through a well-proven model. Optimum management practices, either strategic or tactic, such as planting date, cultivar selection, fertilization, or water and pesticides usage, can be assessed through proven simulation models for making seasonal or withinseason decisions. The capability of AquaCrop model is tested and confirmed by various researches throughout the world. Findings of the field study were used to calibrate the AquaCrop Model for summer chilli in Marathwada region. Results from this study provided a set of first estimates for the calibration of the AquaCrop model on chilli for Marathwada conditions and for further testing and validation of the model at other agroclimatic conditions. AquaCrop model was calibrated by using field data of full irrigation treatment with harvesting index of 75% and water productivity 30 g/m 2 as there was close match between observed and simulated canopy cover with high value statistical parameter of R 2 NS =0.97 and CRM = -0.051. It was also cleared that the canopy cover was overestimated by model particularly during 36 to 84 DAT i.e. during development stage. But the scatter plot clears that as the canopy cover lie on both sides of 1:1 line, there was no consistent over or under estimation.

A field experiment entitled "Impact of Irrigation and Fertigation Levels on Growth, Yield and Quality of Summer Chilli (Capsicum annuum L.)" was carried out during summer season of 2018, in split plot design having main plot treatments as drip irrigation levels viz. I1: at 0.7 ETc, I2: at0.8 ETc, I3: at 0.9 ETc, I4: at 1.0 ETc, and I5: at 1.1 Etc and Sub-plot treatments as fertigation levels viz. F1= 60 per cent of RDF, F2= 80 per cent of RDF and F3= 100 per cent of RDF with fifteen treatment combinations, replicated thrice. Results of the study indicates that for different drip irrigation levels, the ascorbic acid content of chilli was found optimum with drip irrigation at 0.80 of crop evapotranspiration and fertigation with 80 per cent of RDF applied in eleven splits, with 20 per cent saving of irrigation water and fertilizer. Oleoresin content of chilli was not influenced by different drip irrigation levels, however, it was found to be optimum to fertigation with 80 per cent of RDF. The significant differences on dry matter yield and nutrient uptake were observed for different drip irrigation and fertigation levels. As drip irrigation levels between 80 to 100 per cent of crop evapotranspiration were found statistically at par with each other for dry matter yield and nutrient uptake by chilli, irrigation level of 80 per cent of crop evapotranspiration was found optimum among the all tested treatments. Whereas, for different levels of fertigation in eleven splits had significant effect on dry matter yield and nutrient uptake by chilli. Dry matter yield and nutrient uptake were found highest in F3 (fertigation with 100% of RDF) treatment. Further fertigation levels with100 per cent of RDF and 80 per cent of RDF was found statistically at par with each other for the dry matter yield and nutrient uptake. Therefore, fertigation with 80 per cent RDF in eleven splits was found optimum.

Background: Pigeonpea an indeterminate pulse crop with profuse branching responds well to both irrigation and fertilizer. Erratic rainfall distribution pattern exposes this crop to dry spell during its vegetative stage and terminal drought at reproductive stage and the poor crop nutrition further results in to low yield. Under such circumstances it is very difficult to sustain the yield of pigeonpea. Agronomic practices like precise and timely application of drip irrigation along with judicious use of nutrients play a vital role to boost the yield of any crop. Thus the attempts were made to explore the yield potential of pigeonpea under drip irrigation and fertigation management. Methods: The present study was conducted at the experimental farm of AICRP on Irrigation Water Management, VNMKV, Parbhani (MS) during kharif 2018 and 2019. The experiment was laid out in split plot design with main plots comprising of four drip irrigation levels viz. 0.6, 0.8, 1.0 ETc (crop evapotranspiration) and conventional method and sub plots were allotted to four fertigation levels viz. control (no fertilizer), 80% RDF, 100% RDF (25: 50: 25 NPK kg ha-1) and 120% RDF. Result: Drip irrigation at 0.8 ETc recorded higher seed yield, harvest index, water use efficiency, nutrient use efficiency and net returns of pigeonpea followed by 1.0 ETc except in case of water use efficiency. As regards to fertigation studies, higher values of seed yield, harvest index and water use efficiency were recorded with drip fertigation @ 25:50:25 NPK kg ha-1 closely followed by 20:40:20 NPK kg ha-1. However higher nutrient use efficiency and net returns were obtained in drip fertigation @ 20:40:20 NPK kg ha-1.
