(8) Which specific tillage operation, commonly performed in rice cultivation, involves maintaining standing water at a depth of 5–10 cm to reduce water percolation losses and facilitate puddling for effective transplanting, and is known as what?

(9) An advanced method of minimum tillage in which primary tillage is completely avoided and secondary tillage is reduced to row zone/seed bed zone only.

(10) Zero tillage got successful because of ?

(11) Primary + secondary tillage implement

(12) When rice seedlings are grown in nurseries, which implement is used to establish rice seedling in puddled soil condition?

(13) Which secondary tillage operation is primarily performed to pulverize soil clods, level the field surface, and create a fine, well-aerated seedbed that ensures better seed-soil contact and uniform germination conditions for crop establishment?

(14) What is the primary objective of using a disc harrow in agricultural operations is it mainly to cut, lift, and turn the soil, break clods, and incorporate crop residues after primary tillage for effective secondary soil preparation and weed control?

(15) Which tillage that are done for raising crops in the same season or at the onset of the crop season. It is performed when the soil has adequate moisture and temperature conditions for seedbed preparation?

(17) Which of the following is not a precaution to be taken while adopting the zero tillage technique for wheat cultivation in the rice - wheat cropping system ?

(16) It is an advanced method of minimum tillage in which Primary tillage is completely avoided and secondary tillage is reduced to row zone only?

(18) Physical condition of soil obtained out of tillage or it is the result of tillage?

(19) Which tillage done after seeding or planting the crop either at the pre emergence stage of crop plants or while they are in the early stage of growth so that crop plants do not get damaged.

(20) Practice which is used to break hard pan beneath the plough layer, special tillage operation is performed to reduce compaction. Which is not an advantage of this practice?

(21) Which of the following is a characteristic of traditional tillage systems compared to conservation tillage?

(22) which is initial major soil working operation designed to plough the soil deeply to reduce soil strength, cover plant materials known as Primary tillage. It operation is performed to cut, break and invert the soil partially or completely?

(23) Lighter and final tillage operation performed in the soil after primary tillage to create proper soil tilth and surface configuration for seeding and planting with this equipements are used like Harrow, cultivator, sweeps, clod crushers etc?

(24) It is a traditional method of land preparation that involves multiple soil-working operations usually ploughing, harrowing, and levelling before sowing. Which of the following Conventional tillage operation can lead to soil erosion over time?

(25) A wide sweep and trace bar clears strip over the previous crop row and planter opens a narrow strip into seeds are planted and covered. Before sowing, the vegetation present has to be destroyed with broad spectrum nonselective herbicides are used?

(26) Which tillage systems leave less than 15% residue cover planting or less than 560kg/ha of small grain residues equivalent throughout the critical wind erosion period?

(27) It is one of the oldest and most important plough designs, known for its ability to cut, lift, turn, and invert the soil. Components of this are share, share point, cutting edge, wing , gunnel etc. What is the main objectives of this implement.
