during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
in yield in MP-1203 with ZT increased 27.33% over farmers practice by usingMP-1203. The B:C
ratio was observed higher side by using MP-1203 is 2.53 as compared to conventional method
sowing of wheat is 1.48 The B: C ratio was observed higher side in zero-tillage method as
compared to conventional method sowing of wheat. The finding have clearly established that
wheat sowing can be advanced in yield by using MP-1203 over utilization of local variety of
wheat, under zero tillage method it also clearly established that wheat sowing can be advanced in
yield over conventional tillage system.

Maize is an important crop widely grown for food and feed and is one of the most versatile
emerging crops having wider adaptability under varied agro climatic conditions It is mainly
cultivated as rainfed crop in Kharif and as irrigated crop during Rabi. In Khammam district,
Maize is one of the important cereal crop cultivated by farmers which is having a normal area of
13073 ha. It is one of the major crop best suited for Rabi which gives good yield with good
management practices. Unfortunately, much of the expected yields are not realized because of
traditional method of planting and cultivation resulting in low plant population, poor and uneven
development of cobs, limiting moisture levels which affect the crop during the critical stages
resulting in yield loss, nutrient deficiency and wastage of fertilizers during application. This
factors in turn increases cost of cultivation, competition between weeds and main crop for water,
nutrients and other inputs which affect the crop growth because of weed dominance for nutrients.
All these factors together and cultivation of maize in the traditional method of planting by the
farmers were contributing to the less yields of the crop. To overcome this problem, KVK-Wyra
scientists intervened and introduced paired row technique in Maize along with drip irrigation. In
paired row method of cultivation, spacing between plant to plant is 20-25 cm, row to row spacing
is 30 cm and spacing between one pair to another pair is 90 cm. For irrigation and fertigation to
the plants, a drip lateral is spread in between the two rows which help in giving uniform water
and fertilizer to both the rows thus decreasing the no of lateral requirement per acre. Further, due
