Groundnut (Arachis hypogaea L.) genotypes were assessed for pod yield and physiological parameters under heat-stress and non-stress environments. The air temperatures under heat-stress environments were 35C and above during flowering, and below 35C in non-stress environments. Variability was significant for pod yield and physiological parameters among the genotypes under heat stress. A pod yield reduction of 1.5% to 43.2% was observed under heat-stress environments. However, in heat-Tolerant genotypes, either stable or increased pod yield was recorded under high-Temperature stress. GJG 31, ICGV 87846, ICGV 03057, ICGV 07038 and GG 20 showed an increase in pod yield by 9.0% to 47.0% at high temperatures, with a 0.65% to 3.6% increase in pod growth rate, while ICGV 06420, ICGV 87128, ICGV 97182, TCGS 1043 and ICGV 03042 are stable for pod yield and recorded a 0.25% to 3.1% increase in pod growth rate. Pod yield, hundred-seed weight, and pod growth rate under heat stress can be used as criteria for selection of heat stress tolerant-genotypes. Based on stress tolerance indices and pod yield performance, ICGVs 07246, 07012, 06039, 06040, 03042, 07038 and 06424 were identified as heat-Tolerant genotypes.

An efficient protocol for in vitro multiplication of hybrid tea rose cv. Raktagandha was developed using axillary bud segments. Out of different pre-treatments of explants tried, the highest explant survival (78.05%) was obtained with carbendazim (0.2%) + diathane M-45 (0.2%) + 8-HQC (200 mg/l) for 3 h on a horizontal shaker (120 rpm). Sucrose concentration of 30 g/l in the medium seems to be optimal for in vitro shoot multiplication. Murashige and Skoog medium supplemented with 3.5 mg/l BAP + 0.2 mg/l NAA + 0.5 mg/l GA3 was found most effective for culture establishment and shoot proliferation with highest number of micro-shoots (4.62 shoots / explant). Rooting of micro-shoots was induced on half-strength MS basal medium supplemented with NAA (0.5 mg/l) + IBA (0.5 mg/l). The regenerated plantlets were efficiently hardened in glass jars filled with vermiculite + agropeat (1:2) moistened with half-strength MS medium salts and covered with polypropylene lids, thereafter plants were successfully transferred to the glasshouse with good survival. © 2017, Horticulture Society of India.

An investigation was carried out on land capability classification and crop suitability assessment-. Results indicate that all five soil series viz. Gola (PI), Bhatagon (P2), Khambe (P3), Balrampur (P4) and Nohri (P5) series showed highly suitable (SI) for maize crop. Gola (PI) and Khamber (P3) series are highly suitable (SI), whereas, Bhatagon (P2), Balrampur (P4) and Nohri (P5) series moderately suitable (S2) for jute cultivation. Khambe (P3), Balrampur (P4) and Nohri (P5) series are highly suitable (SI) and Gola (PI), Bhatagon (P2) are moderately suitable for paddy cultivation. Gola (PI) series are highly suitable (SI) and Nohri (P5) series moderately suitable (S2) and Bhatagon (P2), Khambe (P3), Balrampur (P4) series are marginal suitable for pineapple and vegetable cultivation. The soil site characteristics of soil units were matched with criteria for land capability classification. The pedons were grouped under the capability subclass Illew (P-l and P-2), IIIws (P-3 and P-4) and IIIsw (P-5) and P-l, P-2, P-3, P-4 and P-5 were grouped under land irrigability sub-classes as A, B, C, C and C respectively. Result findings are in digital maps which are helpful for land use planning towards sustainability for different agricultural practices. © Copyright EM International.

A weed control experiment was undertaken on onion cv. Patna Red comprising of hand weeding and application of weedicides, viz., flushmoralin, pendimethalin and metochlor. Application of pendimethalin and fluchloralin each at 1.0 kg/ha along with one hand weeding gave the best result with regard to weed dry matter content, nutrient uptake and depletion. The results were comparable with three hand weeding treatment.
