Irrigation scheduling of different crops

Estimation of crop water requirement is essential for agricultural planning and irrigation scheduling. The aim of this study was to compute the water requirement of wheat and rice crops for all districts of Haryana. Climatic data on maximum and minimum temperature, rainfall, relative humidity, wind speed and solar radiation were used to estimate the reference evapotranspiration (ETo) at different gridded locations by using Penman Monteith method in MATLAB software.

d of irrigation commonly followed by the farmers in this region is expensive and inefficient since it causes high water and nutrients losses in deep percolation. Keeping this in view, the present study was contemplated with the objective of examining the effect of irrigation scheduling on growth, yield and yield variables and water use efficiency of cowpea.

Water is a vital commodity and it is essentially used for maximizing crop production and productivity. Drip irrigation is gaining popular among the farmers because of its high efficiency and productivity. This study was conducted during the Kharif season of 2018 and 2019 to find the best automated drip irrigation system among the time based, volume based, soil moisture sensor based and tensiometer based drip irrigation in comparison with conventional drip irrigation system.

The field experiment was conducted at Agronomy Farm, Anand Agricultural University, Anand (Lat.: 220 35’ N, Log.: 720 55’ E & 45.1 m above msl) during rabi season in 2011- 2012. The treatment comprised of five levels of irrigation schedule Viz., I1 (CRI, TL, BT, FL, ML, SD), I2 (0.4 IW: CPE ratio), I3 (0.6 IW: CPE ratio), I4 (0.8 IW: CPE ratio) and I5 (1.0 IW: CPE ratio) in randomized block design (RBD) within four replications. The main aim is to quantify the agrometeorological indices of wheat crop.

Designing, establishing and managing irrigation projects, and scheduling irrigation requires estimating a crop seasonal water requirement. Lysimeter experiment conducted on green gram during Kharif season. His experiment was aimed at determining the seasonal crop evapotranspiration (ETc) and crop coefficient (Kc) of green gram crop for different development stages.

An experiment was carried out to study the effect of mulches and irrigation scheduling on the growth and yield of ZT potato under rain fed low land rice ecosystem. The experiment was laid out in split plot design taking three levels of irrigation viz. Single irrigation at 40 DAP (I1), Splash irrigation at 15 days interval (I2) and Irrigation at IW/CPE = 0.6 (IW = 4cm) (I3) in the main plots and three types of mulch management viz.

The available water decreases as world demand for water increases for various purposes such as industrial, agriculture hydropower. To improve the water use efficiency, there is a need to modify traditional irrigation scheduling. In the present study, the CROPWAT model was used to estimation the irrigation scudding for rice and cotton crop to improve water use efficiency. From the analysis, it was found that reference evapotranspiration was almost directly proportional to the radiation and sunshine hours and inversely proportional to the relative humidity.

A field experiment was conducted during summer season of the year 2010 at Anand Agricultural University, Anand, Gujarat to study the influence of date of sowing and irrigation scheduling on productivity of summer moth bean. The results indicated that treatment D2 sowing at (30th January) recorded the highest plant height (10.00 cm, 19.50 cm and 27.05 cm at 30, 60 DAS and at harvest, respectively. While the lowest plant height (6.25 cm, 16.33 and 21.13 cm at 30, 60 DAS and at harvest, respectively) was observed under 20th January sowing (D1).

Rural development as an integrated concept of growth and poverty elimination has been of paramount concern in all the consequent Government Schemes. The major challenge for our Governments is to offer solution that enables rain fed farming towards sustainable agriculture. “Krishi Bhagya” is the Government„s flagship programme is a step towards to achive sustainability among rainfed farmers of the state. Government is supporting farmers to make a farm pond with polythene lining (to prevent percolation), install pump and sprinkler irrigation system (for efficient water utilization).

Maize (Zea mays L.) is one of the most important cereal crop species and is grown throughout a wide range of climates. In India, maize is the most important food crop after rice and wheat. Since 1950, the area, production and productivity of maize have increased more than 3.4, 12 and 4.5 times from 3.2 m ha,1.7 m t and 547 kg/ ha to current level of 8.17 m ha,19.33 m t and 2414 kg/ha, respectively due to increase in maize demand for diversified uses. Maize could be grown in wide ranges of soils and climate throughout the year.

Rice belong to genus Oryza. The cultivated species are Oryza sativa and Oryza glaberrima. Oryza glaberrima has been cultivated in West Africa. Rice is grown under many different conditions and production system, but submerged in water is the most common method use worldwide. Rice is the only cereal crop that can grown for long periods of time in standing water. 57% of rice is grown on irrigated land, 25% on rainfed lowland, 10% on the uplands, 6% in deepwater and 2% in tidal wetland.
