Dear students, in this 9th and highly crucial Horticulture chapter of Class 12 Agriculture strictly known as 'Fruit Production', we will deeply study the massive commercial cultivation of major fruit crops from 1 strictly logical and scientific perspective. Massive fruit production is 100 percent not just 1 simple random process of planting saplings; rather, it is 1 highly advanced and systematically organized modern botanical science. Establishing 1 massive fruit orchard is 100 percent 1 long-term capital investment, making the strict scientific selection of the exact fruit and its highly improved variety 100 percent absolutely necessary. From the strict perspective of the upcoming massive board exams and specifically the highly competitive Rajasthan Joint Entrance Test (JET Exam) and ICAR, this chapter is 100 percent highly scoring and 1 absolute massive milestone for your excellent academic success.
In this highly exciting learning journey, we will 1st logically analyze the massive cultivation of 'Mango', the national fruit of India. We will deeply study its strict botanical name, massive origin place, and specific plant family. In the massive JET Exam, objective questions strictly based on the exact massive improved hybrid varieties of Mango like 'Amrapali' (which is 100 percent highly suitable for massive High Density Planting) and 'Mallika' are 100 percent directly asked. We will logically evaluate exactly how massive 'Veneer Grafting' is 100 percent strictly utilized for its commercial propagation. After this, we will systematically study the massive cultivation of 'Banana'. Since commercial Banana is 100 percent strictly seedless, its massive propagation is scientifically done using strictly selected 'Sword Suckers'.
Moving 1 little further in the highly detailed chapter, we will logically analyze the massive cultivation of Papaya, Guava, and Citrus fruits. Papaya is 1 extremely fast-growing massive fruit crop which is 100 percent strictly propagated exclusively through seeds. The massive 'Pusa Nanha' variety of Papaya is 100 percent highly recommended for strictly planting in kitchen gardens. Furthermore, we will deeply study massive fruit crops that are 100 percent highly suitable for the strict dry and arid massive climate of Rajasthan, such as Ber, Date Palm, Pomegranate, and Aonla. We will logically understand the highly complex and strictly essential scientific processes of 'Training and Pruning', which are 100 percent strictly required in massive Grape cultivation to drastically increase the massive final yield.
Finally, we will completely study the massive scientific management of Plant Protection in massive fruit orchards. Scientifically identifying massive destructive insect pests (like massive Mango hoppers) and highly dangerous viral or bacterial plant diseases (like Papaya leaf curl and massive Citrus Canker) is 100 percent necessary to strictly apply the correct massive chemical control measures. To perfectly ensure your excellent and 100 percent strong board and JET preparation, we have meticulously prepared highly accurate objective questions from all these massive topics.
Feature: This is 1 3-Level based unique quiz. To unlock the next level (Level 2 and 3), students must strictly score at least 70% in the current level, making their board and JET exam preparation 100% strong.
