  • Growth and development are terms that refer to dynamic processes that begin at conception. Human growth is the progressive increase in physical size of a child whereas; human development is progressive acquisition of various skills and abilities. The process of growth and development is predictable and it follows a sequence. Both processes go hand in hand, are interrelated and none occurs apart from the other but the rates at which it occurs might be different. The present paper is an attempt to summarize concept of growth and development.

  • In the present investigation HUR 105 genotype was selected to see the effect of hydro and hormonal seed priming on growth and development of rice crop. Priming of seeds has been done with distilled water (hydro) and two hormones (Kinetin and salicylic acid) and different growth parameters, such as plant height, number of tillers hill-1 , number of green leaves hill-1 , leaf area hill-1 and leaf area index were studied at different study periods under timely and late sown conditions. Primed seeds increased all the growth parameters in respect to non-primed (control) sets.

  • Presentation article the study showed the significant effect of foliar application of micronutrients on all the parameters. The height of plants in T2 increases by 5ml/1000ml solution. The application of micronutrients solution increases the number of branches per plant in T3 (6.69) by 5ml/l 000ml solution of water as compare to control followed by T2 (7.77), T1 (6.21), and T0 (4.87) respectively. Foliar fertilization improves the growth and development by providing essential nutrients. The T2 (35.87 cm) showed the maximum length of branches per plant.

  • For dietary status, growth, development and health, optimal feeding procedures are needed for infants and young children. In order to meet the difference in dietary demands transition foods need to be included in the diet. Diet diversity refers to all food groups being included in the diet. To assess food intake, a food intake questionnaire and a dietary recall method lasting 24 hours were used. Using the seven food groups, diet variety was calculated. ANOVA was used to compare means. Sixty infants and young children have been engaged in these studies.

  • Zinc (Zn) is one of the most essential micronutrients required for normal plant growth and development. Even though considerable quantity of inorganic Zn is applied in soil but significant quantity of it gets converted into unavailable forms. Zn solubilising microorganisms are the potential substitute for Zn supplement to plant from soil. Among the four isolates that were screened for Zn solubilization, fungal ones performed better than bacterial ones and Aspergillus sp. in particular, outperformed every other isolate in the test. It produced a clear halo zone of 22.

  • Very long chain fatty acids (C20 and longer) are synthesized via fatty acid elongases at ER. Plastid generated C16 and C18 fatty acids and malony CoA are substrates for these elongases. The cuticular waxes are a mixture of mostly aliphatic very long chain fatty acids (VLCFA) and variable amount of triterpenoids and phenyl propanoids. Cuticle is composed of inter-esterification of ω and mid chain hydroxy and epoxy C16 and C18 fatty acids and glycerol, and cuticular waxes.

  • The researchers evaluated the growth and development abillity of some hybrid maize varieties grown in Spring 2018 in 4 northern and north central provinces including Viet Tri - Phu Tho, Vinh Tuong - Vinh Phuc, Phu Yen - Son La, Yen Dinh - Thanh Hoa. The experiments were arranged in a completely randomized block format with 3 replicates. Each hybrid maize was cultivated in 4 rows in a 5-m long plot; the distance between two rows was 70 cm and the distance between two plants was 25 cm. Fertilizers applied generally for experiments were 150 kg N + 90 kg P2O5 + 80 kg K2O/ha.

  • Activated charcoal is often used in plant tissue culture to improve cell growth and development by absorbing the beneficial plant growth promoting substances from the media. Thus the main aim of this study was to evaluate the influence of different concentrations of activated charcoal on the recalcitrant varieties of potato. The MS media strength (full and half) did not influence the plant growth and development of potato varieties as both the strengths did equally well in combination with lower concentration of activated charcoal (200mg/l).

  • A field experiment was conducted at University Orchard, Horticultural College and Research Institute, Coimbatore to standardize the cropping density and nutrient requirement on growth and development of banana cv. Quintal Nendran (AAB) during 2015-17. The studies were carried out by planting banana suckers at three spacing levels viz., S1–1.8x1.8 m (3086 plants ha-1 ), S2 - 2.1 x 2.1 m (2267 plants ha-1 ), S3 - 2.1 x 2.4 m (1984 plants ha-1 ) with four fertigation levels viz., F1 - 75 per cent, F2 - 100 per cent, F3 - 125 per cent and F4 - 150 per cent RDF.
