Chubaienla Jamir conducted her research summary at the Sam Higginbottom Institute of Agriculture, Technology and Sciences (SHIATS). The fieldwork for this thesis took place on the farms of SAF-BIN project participants in Madhya Pradesh, India.

Summary

Warm weather during node stage of rice is an increasing problem in rice production in Mandla district of Madhya Pradesh. It leads to high infestation of green semi-looper and hence yield loss. Adaption strategies are required to mitigate these negative climate change effects.

The objective of the study was to assess the effect of different transplanting dates and the application of liquid organic formulations on rainfed rice in regards to growth, yield, economy and quality.

The on farm adaptive research trial was conducted at 18 farmers’ fields in nine villages[1] of Mandla district in Madhya Pradesh during Kharif season, 2013. It was laid out in a randomized block design based on two treatment combinations[2],[3] with 9 replications each. Growth parameters and yield attributes of rice variety MTU1010 as well as % damage due to semi-looper and post-harvest quality factors in addition to economic analysis were measured. Significant difference was tested via F-test.

Modified transplanting date + 3% of matka khad (T1)2 achieved significantly higher values compared to traditional transplanting date + 5% of fermented plant juice (T2)3 for plant height at 30 DAT[4] (31.16 cm, 27.12 cm, resp.), number of tillers hill-1 at 15 DAT (5.00, 3.97, resp.) and crop growth rate at different intervals, e.g. 75 to 90 DAT (2.48, 1.89 g m-2 day-1, resp.). Additionally T1 performed significantly better for panicle length (21.01, 18.04 cm, resp.) and also better for harvest index (35.71, 30.92%, resp.). T1 was also more effective against semi-looper and achieved highest gross (INR 85090 ha-1) and net 64498 ha-1) return and benefit cost ratio (INR 4.13).

For improving the growth and yield of rainfed rice T1 has proven to be most successful for the majority of tested parameters. The success of this on-farm adaptive research trial could be shown through the active participation of the famers. Moreover, it caught also the attention from neighboring farmers, who decided to put the treatments into practice too.
