“…This could be because of the residual effect of NPK application coupled with favourable growing conditions. The present findings are in line with the earlier study conducted by Burio et al (2004), who showed comparable results with increasing levels of N, P, and K.…”

A field trial was conducted on a sandy clay loam soil during rabi seasons of 2020-21 and 2021-22 at the Agricultural College Farm, Bapatla to investigate the residual effect of maize crop residue management techniques and fertilizer levels on growth and productivity of zerotill maize in rice-maize sequence. The experiment was laid out in split-split plot design with four maize crop residue management practices (M1 : Exportation of maize stover, M2 : In-situ burning of maize stover (farmers practice), M3 : Mulching maize stover with rotary mulcher and M4 : Incorporation of maize stover with rotovator) as main plot treatments and three fertility levels (100% RDF, 75% RDF and 50% RDF) as sub plot treatments applied to kharif preceded rice and three fertility levels (100% RDF, 75% RDF and 50% RDF) as sub-sub plot levels applied to succeeding maize. Results revealed that incorporation of maize stover with rotovator (M4 ) applied to preceding rice significantly improved plant height (cm), days to 50% tasseling and 50% silking, cob length (cm), cob girth (cm), test weight (g) and grain yield of maize. Mean values for fertiliser levels revealed that plant height (cm), days to 50% tasseling and 50% silking, cob length (cm), cob girth (cm), test weight (g) and grain yield were registered with application of 100% RDF (S1 ) applied to preceding rice and application of 100% RDF applied to succeeding maize. Thus, incorporation of maize stover with rotovator (M4 ) along with application of 100 % RDF applied to preceding rice and application of 100% RDF (S1 ) to succeeding maize is an optimum and sustainable approach to enhance the growth and productivity of zero till maize in rice-maize system.

To determine the association among yield related traits on grain yield of mutant wheat, an experiment was conducted at the Agricultural Research Farm of R. B. S. College, Bichpuri, Agra (Uttar Pradesh). The application of physical mutagens such as X-rays, gamma rays, and neutrons, as well as chemical mutagens, for inducing variation is well set up. Induced mutations have been applied to the Joint offer of FAO/IAEA Division of Nuclear Methods in Agriculture, more than 1800 cultivars acquired either as direct mutants or derived from their crosses have been released globally in 50 countries. The correlation of twelve characters in wheat induced mutants was investigated. The number of spikelets per spike and spike length both had a significant and positive correlation with yield per plant. Selection for traits that are positively correlated with yield per plant could lead to increased yield. This suggests that selecting for these traits may be more effective in maximising grain yield.

“…A. Burio et al, (2004) observed the correlation coefficient values of growth and yield traits of Kiran-95 wheat variety under different nitrogen levels and placements which will help in estimating the degree of relationship which could be used for predicting the response of yield in any crop. 39 From the above result it can be concluded that depending on quality of water the growth parameters as well as the biochemical parameters also change species wise.…”

The study was aimed to determine the effects of water quality on seed germination and seedling growth of Cicer arietinum and Brassica juncea under laboratory condition at Haldia, West Bengal. Water from four different water bodies was examined including one control. Both the plant seeds and seedlings were treated for 15 days; and this was carried for three times in a year with each type of water. The germination and growth was observed for two weeks and mean readings were taken in the result. Shoot length, root length, number of root hairs, root hair length, and some biochemical assessment were determined. Biochemical assessment includes total carbohydrate, reducing sugar, total non-reducing sugar, protein content and total DNA. It was observed through all the parameters that the seed germination and growth of seedlings were highly sensitive to the quality of water and the polluted water exerted a kind of stress level to their growth. From the result it could be concluded that different quality water had significantly affected the seed germination and seedling growth of two species of plants assessed.
