A field study conducted for two years at the Indian Agricultural Research Institute, New Delhi showed that intercropping potato with fenugreek is highly profitable and provides some in-season income to the potato growers. It also serves as an insurance against complete loss of income when the potato prices crash in the market.

The type specimens of 717 chalcidoid species described by taxonomists from the Department of Zoology, Aligarh Muslim University, India, and their depositories are tabulated. Table 1 lists the holotypes and other type specimens of the species deposited in the Natural History Museum, London, England (BMNH), National Zoological Collections, Zoological Survey of India, Kolkata, India (NZSI), Forest Entomology Division, Forest Research Institute, Dehra Dun, India (FRI), National Pusa Collections, Division of Entomology, Indian Agricultural Research Institute, New Delhi, India (NPC), and the Insect Collection, Department of Zoology, Aligarh Muslim University, Aligarh, India (ZDAMU). The holotypes and lectotypes of 700 species are distributed as follows: BMNH (175), NZSI (34), FRI (28), NPC (131), and ZDAMU (332). The holotypes of 17 species could not be located in ZDAMU, but all of these species are represented by paratypes. A further 23 species whose types are not located in ZDAMU are listed in Table 2.

SummaryStudies on productivity of pigeonpea-wheat cropping systems at the Indian Agricultural Research Institute, New Delhi during 1984–6 revealed that wheat following summer pigeonpea and given 120 kg N/ha produced 4–93, as compared with 451 t grain/ha when it succeeded kharif pigeonpea. Intercropping of preceding pigeonpea with dhaincha for green manure, fodder cowpea and greengram (grain) gave higher yields of 4·35, 397 and 3·68 t/ha respectively than the wheat following pigeonpea alone (3·20 t/ha). Similar effects on wheat straw were also recorded. Summer-sown pigeonpea produced 2·38 t grain/ha without any adverse effect of intercrops. However, kharif pigeonpea produced grain yield half of that obtained in the summer-sown crop. Further, the reductions in grain yield of kharif pigeonpea due to dhaincha, cowpea and greengram were 0·60, 0·52 and 030 t/ha, respectively. Summer pigeonpea + dhaincha-wheat and summer pigeonpea+greengram-wheat proved their superiority over other cropping systems.

SUMMARYField experiments on crop compatibility and spatial arrangements in sorghum were conducted at the Indian Agricultural Research Institute, New Delhi in irrigated conditions in 1976 and 1978. Grain yield of sorghum increased when grown in association with the legumes greengram, groundnut, grain and fodder cow peas and soya bean, compared with sole sorghum. Planting of sorghum in paired rows (30:90 cm) with two rows of intercrop in the 90 cm space produced maximum yields of sorghum and intercrops.

The coelidiinae leafhopper genus Baseprocessa Fan & Li is newly recorded from India based on the description of B. patkaensis Meshram sp. nov. and a proposed new combination, B. serratispatulata (Viraktamath & Meshram) comb. nov. Materials are deposited in the National Pusa Collection, Division of Entomology, ICAR-Indian Agricultural Research Institute (IARI), New Delhi, India. Photographic illustrations, checklist and key to species of this genus along with a distribution map are also provided.

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).
