Grain growth rate

Ebook "Seed biology and yield of grain crops (2nd edition)" of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population.

The model showed matching results for all duplex oxide combinations in varying stress, but the inner logarithmical oxide gave higher crack growth rates than the power law. The power law with the thicker inner oxide showed good results for the change of stress intensity factor and gave the best results when the yield stress was varied. Grain misorientation effect was higher for the duplex oxides with thicker outer oxides.

The study on growth and yield of chickpea (Cicer arietinum L.) as influenced by seed rate and seed priming was conducted during Rabi 2017-18. The experiment consisted of nine treatment combinations of three seed rates viz. 60 kg, 80 kg and 100 kg ha-1 in main plots and three seed priming treatments viz. control, water and NaCl in sub plots were tested in split plot design with three replications.

In Indian agriculture, food grain crops cover the dominant part of cropped area (65 per cent). India is continuously facing pressure on the demand side due to limited land availability, steady population growth and several other production constraints, which appear as obstacles for supply of food grains. In the present study, growth in area, production and productivity of food grains were estimated using the linear trend and compound growth function.

The present study was conducted in Kolhapur district of Maharashtra state during 1980-81 to 2011-12. The study found that area under wheat, bajra, gram, redgram had declined and area under rice, Kharif jowar, Rabi jowar, greengram, blackgram, fruits and vegetables, soybean sugarcane and groundnut was increased. Similarly area under total cereal and pulse was also declined.

An experiment was conducted in rabi season during 2012-2013 and 2013- 2014 to find out the effect of cereal crops (Wheat, Oat, Barley) and cutting schedule on forage and grain yield. The study revealed the maximum chlorophyll accumulation in Barley and wheat during initial stage at 95 DAS and wheat and barley during reproductive stage at 30 DAS. Cutting at 50 DAS is proved beneficial on chlorophyll accumulation. Photosynthetic rate were maximum in wheat at 90 DAS.

Seed is a basic and costly input in agriculture. Genotypes of a crop varying in seed size and growth behaviour may differ in optimal seed rate for realizing high grain yields. Field experiments were conducted for three years at Punjab Agricultural University, Ludhiana, India to study the growth, productivity and economics of kabuli chickpea genotypes in response to seeding rate.

In the changing climate scenario, drought could be continued as a major abiotic limitation for crop productivity. Finger millet although known for its drought tolerance, the drought stress decreases the grain yield from 25 to 100 percent depending on the duration and magnitude of drought stress. Present study was conducted to explore the genetic variability of selected genotypes over the ruling varieties if any, based on the extent of reduction in grain yield, and dependent photosynthetic traits due to moderate drought stress for 18 to 20 days (grand growth to flower primordial initiation).

A field experiment was conducted during Kharif season of 2016 at Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur. The experiment was laid out in Factorial Randomised Block Design (FRBD) with two factors: sowing techniques with two levels (broadcasting and line sowing) and seed rate with five levels (80, 90, 100, 110 and 120 kg ha-1 ).

Three N levels (N1: 120, N2: 150, N3: 180 kg/ha) and four Si applications (Si0: Control, Si1: 5%, Si2: 10% and Si3:15%) were applied to the rice crop. Number of tillers m-2 and relative growth rate were significantly highest with 180kgN ha-1 from 30-45DAT but from 60DAT upto harvest, these growth parameters were significantly highest with 120kgN ha-1 . However, number of tillers m-2 and relative growth rate were significantly highest with 15%Si.
