Crop Production and Management
What is irrigation? Describe two methods of irrigation which conserve water.
The process of supplying water to crops at regular intervals is called irrigation. Along with water, fertilizers and minerals present in the soil are also get absorbed. Water is essential for the germination of seeds. The time and frequency of irrigation vary from crop to crop, soil to soil, and season to season.
Two irrigation methods that conserve water are:
(a) Sprinkler: This system is used for uneven land. The perpendicular pipes have rotating nozzles on top. They are connected to the main pipeline. When water is allowed to pass through the main pipeline with pressure, it escapes through the rotating nozzles. In this way, the water gets sprinkled on the crop.
(b) Drip irrigation – In this system waterfall drop by drop directly near the roots with the help of pipes or tubes. It is the best technique for watering gardens and trees. It is best in a region where water availability is poor.

What our students and parents say about us!
Saiyam is using EduSaksham online courses from past one year. He is able to complete his tutorials, worksheets, and assignments on his own. Once he is done with worksheets, he can check his answers and if he has done any mistakes, then he can check the correct answers and explanations. They have been given so well that he is able to understand them himself and rarely he asks us for any clarification. He enjoys using the platform and has learned and improved a lot in Mathematics. I would recommend EduSaksham to all parents who want their kids to learn in a structured way and also enjoy the learning process.
Neeraj (Saiyam's Father)
I would like to thank Edusaksham on behalf of my son Aditya who attended " Math Olympiad crash course for 5 weeks". As per Aditya, this course helped him to understand new topics like Roman numerals and decimal places which were not taught in his school till date and had a better understanding of other topics. I personally thank EduSaksham for all the help and support.
Geeta Bansal (Aditya's Mother)
We had a good experience with EduSaksham. Because sheets are available online, Vedant enjoyed doing more and more sheets without any reminders. I could leave him on his own as he was very much motivated to cover the topics. Practice is very important in maths but it becomes difficult for us to prepare sheets, I am glad we found EduSaksham where in a lot of in a lot of sheets are available for practice and the quality of questions are also good. As it's a venture from IITians we could think of giving it a try and I am glad we tried
Shikha Chowdhary (Vedant's Mother)
I have grown up in a family where my father used to give me practice maths paper every day which I need to finish before I go to play. I think that strong foundation of solving new questions every day helped me to clear my IITJEE exam. But as working women, I always had time challenge to create practice Math papers for my daughter. Thanks to EduSaksham, their questions are so logical and conceptual that I don't feel the guilt of not creating practice questions by myself :). There are plenty of worksheet along with the tutorials for each chapter. It has made parents life easier :) And the best part is my daughter loves doing it. Thank you EduSaksham.
