PERFORMANCE OF PRILLED UREA AND UREA SUPER GRANULES IN CHICKPEA CULTIVATION

Abstract

The experiment was conducted during the period from November 2012 to March, 2013 to study the performance of prilled urea and urea super granules in chickpea cultivation. The variety BARI Chola 9 was used as test crop. The experiment consists of the following treatments: T 1 = Prilled urea (PU) broadcasted; T 2 = PU given between two rows; T3 = Urea Super (iranules (USG) placed at 10 cm distance (avoid one row); T 4 = USG placed at 10 cm distance (avoid two rows); T 5 = USG placed at 10 cm distance (avoid three rows); T6 = USG placed at 20 cm distance (avoid one row); 1'7 = USG placed at 20 cm distance (avoid two rows); T 3 = USG placed at 20 cm distance (avoid three rows): T 9 = USG placed at 30 cm distance (avoid one row); T 10 = USG placed at 30 cm distance (avoid two rows); I' = USG placed at 30 cm distance (avoid three rows): T 12 = USG placed at 40 cm distance (avoid one row); T 13 = USG placed at 40 cm distance (avoid two rows) and T 14 = USC placed at 40 cm distance (avoid three rows). USG was placed at 10 cm depth at each case. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. At 20, 40. 60, 80 and 100 days after sowing (DAS) and harvest, the tallest plant (14.37 cm, 27.28 cm, 45.07 cm, 52.52 cm, 58.76 cm and 61.23 cm) was observed from T 7 [USG placed at 20 cm distance (avoid two rows)] and the shortest plant (10.35 cm, 23.26 cm, 35.32 cm. 41.52 cm. 47.40 cm and 49.27 cm) was recorded in T 14 [[JSG placed at 40 cm distance (avoid three rows)]. The minimum days from sowing to harvest (122.33 days) was recorded from T 7 [USG placed at 20 cm distance (avoid two rows)], while the maximum days from sowing to harvest (135.33 days) was found from T14 [USG placed at 40 cm distance (avoid three rows)]. The highest pods plant - ' (68.60), seeds podS ' (2.87), weight of 1000 seeds (221.81 g), seed yield (1.98 t ha d ) and stover yield (2.87 t hi') was recorded from T 7 [USG placed at 20 cm distance (avoid two rows)], while the lowest number of pods plant ' (53.27), lowest number of seeds podS' (1.77). lowest weight of 1000 seeds (188.79 g), lowest seed yield (1.27 t hi') and lowest stover yield (1.90 t haS') was observed from T 14 [USG placed at 40 cm distance (avoid three rows)]. This type of USG application showed bener performance than prilled urea given in two rows but not with broadcasted prilled urea.
