“…The number of grains per cob is one of the most important yield contributing character in maize crop. Data presented in table 1 [5] also observed significant decline in the number of grains per cob, 100 grain weight and other yield contributing characters with the delay in sowing time of maize.…”

“…The same conclusion was also reported by Noferesti et al (2006) [9] , delay of sowing leads to reduction in leaf area index of maize because of the shortening of growing cycle. [8] and Khan et al (2002) [5] . Significantly higher grain yield (3.48 and 3.73 ton ha -1 ) was obtained in popcorn planted with spacing of S 1 (60cm× 20cm) during 2016 and respectively over S 2 (60cm× 15cm).…”

“…In 1923, it was first time reported that B is essential for cell structure of plants (Warington, 1923). The possible roles of B include sugar transport, cell wall synthesis, lignification, cell wall structure integrity, carbohydrate metabolism, ribose nucleic acid (RNA) metabolism, respiration, indole acetic acid (IAA) metabolism, phenol metabolism, and as part of the cell membranes (Parr & Loughman, 1983; Ahmad et al,2009) [5] . Salicylic acid (SA; 2-hydroxybenzoic acid) is an endogenous growth regulator of phenolic nature, which is normally.…”

Two field experiments were conducted at DARS Budgam, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir during 2016 and 2017 under rainfed conditions with the objective to study the growth and yield of popcorn at different sowing dates, plant spacing and nitrogen levels. Experiment was laid in split-split plot design assigning three Sowing Dates 19 th Standard Metrological week (May 02-May 08) (D1), 21 th Standard Metrological week (May 16-May 22) and 23 nd Standard Metrological week (May 30-June 05). Two plant spacings where maintained viz: S1i.e 60cm X 20cm (83000 plants ha -1 ) and S2 i.e. 60cm X 15cm (104166 plants ha-1 ) along with three nitrogen levels viz: N1 =90 kg ha -1 N2 =120 kg ha -1 and N3=150 kg ha -1 . The results revealed that grain and stover yield of maize increased significantly for maize sown in 21 th standard meteorological week with concomitant increase in its yield attributes viz., cob length, cobs per plant, no. of grains per cob and 100-grain weight and growth characters like plant height, number of leaves per plant, leaf area index and dry matter accumulation which had longer vegetative phase than late planting dates for both the years. Among planting density, 60cm×20cm (S1) recorded significantly higher grain yield (3.48 and 3.73 ton ha -1 ) and stover yield (5.76 and 6.12 ton ha -1 ) for the year 2106 and 2017 respectively. Growth and yield attributing characters also recorded highest value with planting density 60cm×20cm (S1). Popping percentage recorded for plant spacing S1 (60cm×20cm) was statistically superior as compared with same of S2 (60cm×15cm). As far as Nitrogen levels are concerned, growth characters like plant height, total number of leaves per plant, dry matter accumulation increased significantly with 120kg/ha nitrogen. Also grain and stover yield showed significant and consistent improvement with increased dose of nitrogen (120 kg/ha). Yield attributing characters showed significant improvement with increasing the level at 150kg/ha. Also popping percentage and nutrient content of plant at anthesis and grain was significantly higher for 150kg/ha nitrogen whereas popping volume and nitrogen content in stover was statistically at par with respect to three nitrogen levels.

“…Higher growth and yield parameters were mainly due to higher values of growth attributes in CP-818 at all stages of crop growth coupled with its higher photosynthetic efficiency due to its optimum LAI and canopy spread which might have led to stimulation of longer sink in terms of longer cobs. Khan et al (2002), Golla et al (2019), Dahmardeh (2012) and Maga (2015) also reported differential response of maize varieties when exposed to different environmental conditions by means of sowing at different dates. It is also well-known fact that number of kernels per cob were higher in longer cobs than small ones apart from this the better cob filling resulted in higher kernel yield.…”

A field experiment was conducted at college of Agriculture, UAHS, Shivamogga during kharif 2015 to study the effect of date of sowing and hybrids on growth and yield of Maize (Zea maysL.). The experi-ment was laid out in randomized complete block design (RCBD) with factorial concept and replicated thrice. There were eight treatment combinations which includes four dates of sowing (15thJune, 30thJune, 15thJuly and 30thJuly) and two hybrids (PAC-740 and CP-818). Crop sown on 15thJune recorded significantly higher plant height (201.03 cm), number of green leaves (3.03), leaf area (992.49 cm2), LAI (0.74), total dry matter (305.65 g), cob length (22.16 cm), kernels cob-1 (670.93), kernel yield cob-1(230.95 g), test weight (43.08 g), kernel yield (7632.57 kg ha-1), stover yield (9512.56 kg ha-1) andhar-vest index (44.52 %)as compared to other sowing dates. Among the hybrids CP -818 recorded significantly higher plant height (191.85 cm), number of green leaves (2.72), leaf area (954.32 cm2), LAI (0.71), total dry matter (277.65 g), cob length (19.81 cm), kernels cob-1 (541.88), kernel yield cob-1(207.71 g), test weight (39.16 g), kernel yield (7060.72 kg ha-1), Stover yield (8839.98 kg ha-1) and harvest in-dex (44.44%) as compared to PAC-740. The interaction between dates of sowing and hybrids are non-significant.

“…In some places, it causes enhancement in crop productivity while mostly results in reduction [10][11][12][13][14][15][16][17][18]. In sustainable farming, organic manure is the most common fertilizer used in the developing countries [19][20][21][22][23][24][25][26][27][28][29][30][31]. For sustainable growth, the most important step is the selection of the best variety for production [9].…”

Climate change is one of the detrimental factors for plant growth. A change in temperature can lead to a high loss in crop productivity. Keeping the detrimental effect of climate change on plant growth and productivity, research was carried out to mitigate the climate effect on crop productivity. Ten maize hybrids and varieties were selected for the experiment and were sown on five different sowing times. The experimental analysis was carried out in Randomized Complete Block Design with split plots arrangement having three replications. Sowing times were allocated to main plots while varieties and hybrids were allotted to the subplots, respectively. The results revealed that different varieties and hybrid shows a different response to variant sowing times. Maximum plant height was recorded by SB-989, maximum biological yield was recorded by Azam variety while maximum grain yield was recorded by SB-909 hybrid maize cultivar. Similarly early sowing time 5 th June showed better results in terms of plant height, grain yield and biological yield. From the results, it was concluded that maize variety showed by sown on 5th June to attain maximum output in terms of yield and yield attributes.
