The development of maize in shade areas is one of the efforts to increase the national maize production.The study objective was to determine the growth and yield adaptation of hybrid maize in shaded areas. The study was conducted in the sengon forest area of Kalices Village, Patehan District, Kendal Regency from March to September 2020. The study was designed using a randomized block design with split-split plots with treatments including: a) shade density (0%, 20% and 40%) as the main plot; b) cultivation technology (PTT and existing farmers) as sub-plots; and c) varieties (JH 37, Nasa 29 and Bisi 18) as sub-plots. Each treatment was replicated 3 times in order to obtain 18 treatment combinations and each replication was planted in a plot with a size of 350 m2. The parameters observed included the percentage of plants growing, plant height at harvest, age 50% male flowers, age 50% female flowers, cob height, cob length, cob weight, cob diameter, number of rows per cob, number of seeds per row, weight of dry seeds, seed moisture content, yield per plot and yield per hectare. The data were processed by analysis of variance and if there is a significant difference, it was further tested with DMRT at the 5% level. The results showed that the shading had a very significant effect on most of the yield components, namely cob length, number of seed rows per cob, wet and dry shell weight per 10 cobs, wet stubble weight per 10 plants, wet stubble weight, and dry shell weight. However, there is no significant effect on the growth components of growth power, cob circumference and cob position. The growth and yield adaptation of maize was better at 20% shade density compared to 40% shade density. On land with a shade density of 20%, the highest productivity was obtained in the Bisi 18 of 5.9 t/ha with a potential yield of 62.7%, followed by Nasa 29 of 5.8 t/ha with a potential yield of 58.41%, and JH 37 as much as 5.2 t/ha with a potential yield of 25%.

A field experiment was conducted at Nalanda College of Horticulture, Noorsarai, Nalanda during summer 2017 to assess the effect of complementary and sole applications of organic and inorganic fertilizers on the growth and yield of bottle gourd under onion-onion-bottle gourd crop sequence. The experiment consists of seven treatments viz.,T1-Inorganic fertilizers (120 Kg N: 60 Kg P2O5 and 40 Kg K2O); T2-50% NPK through inorganic fertilizer + 50%N through FYM; T3-50% N through FYM + 50% N through VC; T4-1/3 of N through FYM + VC + Neemcake; T5-50% N through FYM + PSB + Azotobactor; T6-T3 + PSB + Azotobactor and T7-T4 + PSB + Azotobactor. These seven treatments were replicated thrice in Randomized Block Design. Results revealed that T1-100% NPK through inorganic fertilizer recorded 225.7 q ha-1 fruit yield, which was statistically at par with T2 and T6 producing (211.8 and 209.5 q ha-1). Vine length differed significantly at all the growth stages. T1 recorded maximum vine length (51.8, 370.3 and 464.7 cm) at 30, 60 and 90 DAS, which was significantly higher over T5 at 30 DAS, over T4 and T5 at 60 DAS and over T5 at 90 DAS. Among organics, T6 recorded longest vine, while T5 recorded shortest. No. of branches were found non-significant at 30 DAS but it become significant at 60 and 90 DAS and found significantly highest in T6 over all the treatments. After completion of the cropping system; onion-onion-bottle gourd, soils were subjected to analysis. pH differed significantly, while non-significant difference were observed in EC and soil Org-C. Similarly, available N and P concentration were also found non-significant due to different fertilizer sources, but the concentration of available K differed significantly and found highest in T1 which was at par with T2. T1-100% inorganic fertilizer sources recorded highest gross return, net return and B: C ratio followed by T2. On the basis of result it has been concluded that T2 having 50% NPK through inorganic fertilizer + 50% N through FYM may found suitable for sustainable bottle gourd production as it performed at par with T1 in respect to crop growth and yield.

O experimento foi desenvolvido no campo experimental da Embrapa Mandioca e Fruticultura Tropical, em Cruz das Almas, Bahia, no delineamento em blocos casualizados, com cinco tratamentos e cinco repetições. Foram obtidos dados biométricos (altura de planta, diâmetro de caule e área foliar) e de produção. Não houve diferença significativa entre as médias de crescimento e produtividade do mamoeiro nos diversos tratamentos, indicando não haver diferença entre as fontes nítrica e amoniacal para fertirrigação. A substituição do sulfato de amônio por nitrato de cálcio como única fonte nitrogenada para o mamoeiro promoveu um ganho de produtividade de 14,79%, elevando, porém, o custo de produção em 649,84%. A aplicação de nitrogênio ao solo no período de 12 meses, considerando 50% do período com sulfato de amônio e 50% com de nitrato de cálcio, não causou acidificação ou aumento do pH do solo. UNITERMOS: Fertirrigação, parâmetros biométricos, produtividade.  SOUZA, T.
