The analysis of variance for combining ability of all the traits showed that variances due to treatments, parents, hybrids were highly significant. The line 'CRMS 32A' and testers viz. 'Super rice-8' , 'R 1099-2569-1-1' and 'Jitpiti' were identified as good general combiners. The significant differences between lines x testers interaction indicates that SCA attributed heavily in the expression of these traits and demonstrates the importance of dominance or non additive variances for all the traits. The hybrid 'CRMS 32A'/'R 1099-2569-1-1' and ' APMS 6A'/'Super rice-8' were promising for grain yield. The magnitude of relative heterosis, heterobeltiosis and standard heterosis were also estimated for different characters. A high degree of relative heterosis was observed for grain yield (20.45-82.37%) in the hybrids viz.

Out of 27 test crosses evaluated, 10 restorers, 8 partial restorers and 9 partial maintainer cross combinations were categorized on the basis of pollen fertility and spikelet sterility. Three genotypes K-08-61, K-08-60 and Pusa Sughand-5 were found as effective restorers for all the three CMS lines with spikelet fertility above 83% in F 1 s for data pooled over environments, besides one more genotype K-08-59 depicted restoration only with the introduced CMS line IR-68888A.

Our results demonstrated that application of FYM @ 20 t/ha with soil test based application of nutrients recorded significantly highest number of millable canes of 134.3 thousand/ha and number of shoots (142.2 thousand/ha) at 150 DAS. However, cane length, cane diameter, single cane weight, cane yield and sugar yield were statistically at par with either application of 100% RDF plus FYM @ 20 t/ha or with the soil test based application of nutrients along with biofertilizers and 10 t/ha of FYM. With 20 t/ha of FYM and chemical fertilizer, the build-up of organic carbon content, N, P, K, Zn, Fe, Cu and Mn were significantly higher than the treatments containing either 10 t of FYM/ha or no manure. Application of FYM or biofertilizers or both along with RDF or STB nutrient application resulted in 12.8 to 17.9% higher cane yield, resulting in additional net returns of ₹ 20592 to 45230/ha as compared to recommended dose of inorganic fertilizers alone. Our study showed that higher cane and sugar productivity and economic returns can be achieved by applying either 20 t of FYM or 10 t of FYM along with bio-fertilizers.

CP48-103) that cultured on a selective medium containing different levels of NaCl (0, 0.2, 0.4, 0.6, and 0.8% NaCl). A total of four plants regenerated from the tolerant calluses were selected but the best of them in vigor grown in in vitro and hydroponic systems under salinity stress to comparison with source variety. With increasing supply of NaCl in both systems, root growth was more adversely affected than was shoot growth. Chlorophyll contents showed a decreasing trend and dry matter yield of plants reduced but in a slow rate in tolerant somaclonal than source variety. The biochemical analysis showed that at high salt concentration, Cland Na + content in shoot and root increased. With rising salt concentration from 0 to 0.8%, content of Clin shoot and root of tolerant variant changed lower than parent showed that this variant had genetic lowest ratio of shoot/root chloride and had minimum transport of Clto shoots. Also this variant had high content of Ca 2+ in shoot and high K + /Na + ratio at all salinity levels. Thus it probably has genetic potential to avoid harmful ions uptake.

However, to date, there has been little investigation of patterns of genetic variation in the response to water stress in sugarcane. It has been reported [1] that formative phase is the period when 70-80 % of cane yield is produced and drought during this stage affect cane yield adversely [2]. The tillering and grand growth stages of sugarcane crop, known as the sugarcane formative phase, have been identified and illustrated as the critical water demanding period in sugarcane [3]. Water relations in crop physiological processes and photosynthetic responses to water deficit stress during these growth stages could therefore be convenient in identifying drought tolerant genotypes [4]. Morpho-physiological attributes which impart resistance/tolerance or susceptibility to a biotic and abiotic stress are important from crop production point of view. A sugarcane variety possesses characteristic(s) divulging resistance/tolerance to an abiotic/biotic stress, with suboptimal cane and sugar yield, could be utilized as a parent for contributing the respective trait to the offspring. Adverse effects of water deficit on morphological, physiological, and biochemical processes can be confirmed in all plant parts. In condition of water stress, common physiological alterations included reduced leaf water potential and the relative water content [5], gaseous exchange as well as photosynthesis [4]. Therefore, metabolic changes such as enhanced osmoregulation [6] may occur along with significant changes on the plant growth, in response to the lower cellular turgor pressure [7]. Thus, physiological studies on sugarcane may identify clones more tolerant to water stress and ultimately improve crop productivity. Though breeding programmes in sugarcane with increased yield under normal conditions were attempted to improve drought tolerance, such studies have shown that varieties being tolerant remained turgid and maintained near-optimum growth for longer time [8]) that necessitates identification of drought tolerant genotypes with desirable agro-morpho physiological traits. Present study was envisaged to assess the genetic variability for cane yield components, quality parameters and some physiological traits under water stress conditions. Materials and Methods Present investigation was carried out at experimental area of PAU, Regional Research Station (RRS) Kapurthala, Punjab. The Experimental site is located at of 31.38°N longitude and 75.38°E latitude at an elevation of 225 m above mean sea level (amsl) having clay loam soils with pH of 8.3-8.7. The experimental plant material consisted of 30 diverse clones of Kharif sugarcane comprising nine commercial released varieties and twelve elite clone selections from Punjab, five introductions procured from RS Anakapalli and four ISH clones collected from SBI, Coimbatore. All the 30 clones were planted during spring 2016-17 in the first week of March in a randomized complete block design with two replications in normal (E1) and water stress (E2) environments. Standard agronomic practices as per package of practices of the PAU for field crops were followed to raise the ideal crop stand except irrigation in water stress (E2) environment. Irrigation was suspended for 2-3 weeks interval in water stress (E2) environment at critical growth stages of sugarcane viz., germination, tillering and grand growth stage. Each genotype was represented by a plot of four rows of 6m length each. Inter row spacing was maintained at 90 cm and seed rate in both the environments was kept 12 healthy buds per running 1 metre row.

Huge quantities of biodegradable waste are being generated in rural and urban areas that threaten the environment with pollution and contamination. These wastes can be converted into valuable composts which have long been recognized in agriculture as beneficial for plant growth and yield and the maintenance of soil fertility rather than when they are directly applied. Vermicompost is stable, fine granular organic manure, which enriches soil quality by improving its physicochemical and biological properties. It is highly useful in raising seedlings and for crop production. It is becoming popular as a major component of organic farming system. In this review the details about the process of vermicompost production will be described with its effect on plant growth, soil and environment.
