SUMMARYIn field trials made for two years in the dry period of a semi-arid tract under natural precipitation at the Indian Agricultural Research Institute, New Delhi, overnight seed-soaking of wheat in 0·5% solution of 2-chloro-ethyl-trimethyl ammonium chloride (CCC) prior to sowing increased the grain yield. When treated with foliar application of the chemical in concentrations ranging between 40 and 1000 mg/1, wheat plots yielded better than did the untreated control, but no consistency was noted between the concentrations or stages of their application. The benefit from CCC was due to more root growth, increased stomatal resistance and higher leaf water potential. Treated plants extracted more water from deeper soil layers, increasing their water-use efficiency.

SummaryField experiments were made under natural rainfall during the winter seasons of 1972–3 and 1973–4 at the Indian Agricultural Research Institute, New Delhi, to study the soil water use by barley varieties as influenced by nitrogen rates, mulching and foliar application of antitranspirants. Both Ratna and Vijaya varieties of barley had similar efficiency of water use.Total water use was not much different for various treatments but straw mulch and kaolin decreased evapotranspiration at tillering and pre-flowering stages enabling the plants to use more water at critical stages of grain formation. Application of nitrogen, straw mulch and a foliar coating of kaolin increased the efficiency of water use.

SummaryField trials were made in the rainy seasons of 1970–4 at the Indian Agricultural Research Institute, New Delhi, to evaluate several systems of intercropping maize and sorghum with soya beans. Maize yields were not affected by intercropping with soya beans but sorghum yields were reduced. Though the yield of soya beans when intercropped was less than that of a sole crop, the combined grain yield of the two crops in an intercrop was more than the individual components. Land equivalent ratio (LER) increased to a maximum of about 48 and 31% by intercropping maize and sorghum with soya beans compared with the cereal sole crops. Maize rows planted 120 cm apart and intercropped with two rows of soya beans or sorghum planted 90 cm apart intercropped with one row of soya beans proved to be the best intercropping pattern.

A field experiment was conducted during kharif season of 2015 and 2016 at research farmof the ICAR- Indian Agricultural Research Institute Regional Station Pusa, Samastipur, Biharto determine the foliar feeding of micronutrients (iron and zinc at different growth stages)on growth, yield and economics of rice in middle Gangetic plains of Bihar. The experimentwas laid out in randomized block design consisting of 9 treatments with 3 replications. Thetreatments consist of 0.5% spray of Zinc Sulphate and 1% spray of Ferrous Sulphate at fourdifferent growth stages i.e. 40, 50, 60 and 70 days aĞer transplanting (DAT) and one con-trol. The results shown significant increasing trends of growth, yield aĴributes and yield ofrice with four sprays of 1.0% solution of FeSO4at 40, 50, 60 and 70 days and three sprays ofZnSO4at 50, 60 and 70 days recorded significantly higher plant height, effective tillers/m2,panicle length, grains/panicle, 1,000-grain weight, biological yield, grain yield and straw yieldat maturity. These treatments also gave significantly higher net returns and benefit: cost ratioover the control.

SUMMARYSix intercropping systems and four levels of nitrogen were compared at the Indian Agricultural Research Institute, New Delhi, in the summer rainy seasons (July-October) of 1978 and 1979. The maximum increase in sorghum yield was obtained when it was associated with fodder cowpea, followed by association with grain cowpea and greengram. The application of 40, 80 and 120 kg N ha−1 increased sorghum yield by 8.6, 16.1 and 18.2% in 1978 and by 2.9, 8.1 and 14.1% in 1979, respectively, compared with unfertilized sorghum. The nitrogen uptake by sorghum, and by the total system, was greater in sorghum-legume intercropping systems than in sole sorghum. Nitrogen application also increased the nitrogen uptake by sorghum and by the whole system.

In the publication by Kaur et al. (2020), the depository for the holotype of Chimarra gangtokensis new species was given as “(NPC)”, but no corresponding explanation for this acronym was provided in that publication. Therefore, the name of the species is unavailable (International Code of Zoological Nomenclature 1999, Art. 16.4.2). We clarify here that the holotype is a male deposited in the National Pusa Collection, Division of Entomology, Indian Agricultural Research Institute, Pusa, New Delhi (NPC). The purpose of this note is to validate the name of the new species from the publication date of this erratum by a reference to the original description and diagnosis as an indication (International Code of Zoological Nomenclature 1999, Art. 13.1.2).
