The field study was carried out during two consecutive years of 2013-2014 and 2014-2015 at pilot area of Kannauj, Farrukhabad, Unnao, Hardoi and Mainpuri, C.S. Azad University of Agriculture and Technology, Kanpur, under NABARD and RKVY Projects in 25 villages, where maize and potato are cultivating by farmers as a major enterprises. The cultivars, Azad Uttam and short duration hybrid maize, Kufri Bahar, Kufri Pukharaj, Kufri Pushker, Kufri Ashok, Kufri Anand, Kufri Satlaj, Kufri Jawahar, Kufri Jyoti, Kufri Gulal of potato and ICGV 93468 (Avtar) and Dh 86 of summer groundnut and Sonalika of coriander for green leaves were planted in selected area of 25 villages. The average productivity of maize recorded 30.05 q/ha. The average yield of potato tubers, grown after maize was noted 355.00 q/ha. The summer groundnut yielded by 30.10 q/ha. The coriander grown during mid rainy season between maize and potato crops yielded green leaves by 52.50 q/ha. The highest net return was found Rs. 512875.00 /ha under maize-coriander leaves-potato-summer groundnut. Maize-potato-summer groundnut gave net return Rs. 224480.00/ha. The lowest net return was computed Rs. 121490.00/ha in maize-potato cropping system. The net income of farmers increased 1.80 and 4.22 fold due to maize-potato-summer groundnut and maize-coriander leaves-potato-summer groundnut cropping system, respectively, as compared to maize-potato. Similarly, multiple/relay cropping index increased to the extent of 2.80 and 3.00 by growing of maize-potato-summer groundnut and maize-coriander for green leaves-potato-summer groundnut, respectively, over maize-potato / conventional system (1.80)

Cocoa butter is an important ingredient in the confectionery industries because of its unique physicochemical properties which is given by its peculiar fatty acid composition.

Investigation on the effect of different fertigation levels and soil application of fertilizers was carried out at Dr Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra during rabi season of 2018-19. Akola Safed cultivar (white onion) with spacing of 15 x 10 cm, was used for the study. The treatments comprised of one treatment of application of recommended dose fertilizers (RDF) to the onion crop planted as per traditional system and irrigated by surface irrigation system and three treatments of fertigation with 100%, 80% and 60% of RDF respectively (drip irrigation) with five replications in randomised block design. Fertigation with 100 % RDF recorded highest values of average weight of bulb (148.5 g), total bulb yield (32.28 t/ha), marketable bulb yield (27.85 t/ha), per cent marketable bulb yield (83.17%) followed by fertigation with 80 % and 60% of RDF. The lowest values were recorded in soil application of fertilizers with RDF. 71.7%, 54.87% and 21.58% more yield of onion over conventional method of irrigation and fertilization was obtained by fertigation of 100%, 80% and 60% RDF, respectively. The total water requirement of onion under surface irrigation was found to be 1000 mm, whereas it was found 623.19 mm when drip irrigation was used for fertigation. Thus, by using drip irrigation, 37.68% irrigation water was saved over surface method of irrigation. The crop water use efficiency in surface irrigation was 0.191 t/ha-cm whereas in fertigation with 100% RDF it was 0.518 t/ha-cm followed by 0.467 t/ha-cm and 0.381 t/ha-cm in fertigation of 80% RDF and 60% RDF, respectively. Highest benefit cost ratio 2.77 was recorded in fertigation of 100%, RDF. It is concluded that fertgation with 100 % recommended dose of fertilizers (N:P:K:S) with 11 given splits, is most suitable in order to get maximum yield, water use efficiency and benefit cost ratio for onion crop

In India, maize is emerging as the third most important crop after rice and wheat. Maize is one of the most widely distributed crops in the world and it contributes to food stock in most of the developing nations. It is used directly for human consumption, animal feed, corn starch industry, corn oil production, baby corn and in industrially processing foods. India is the fifth largest producers of maize in the world and contributes 2.5 percent of the global production and has 4.87 percent of the global area. Maize can be cultivated in both kharif and rabi season. The secondary data of area, production and productivity of maize between the periods 1990-91 to 2018-19 was collected from Ministry of Agriculture & Farmers Welfare, Govt. of India. The collected data was analyzed by using of descriptive statistics and linear growth rates (Compound Annual Growth Rate). The study revealed that area and production of maize has been increasing. The productivity of maize is drastically increasing due to availability of high yielding varieties of seeds and new technologies in cultivation methods
